For individuals suffering from allergies or asthma, air conditioning can be both a blessing and a curse.
In this post, we’ll explore how air conditioning affects allergies and asthma, offering practical tips to keep your home comfortable without triggering respiratory issues.
While air conditioning might not cure allergies or asthma, it can help alleviate symptoms in certain situations. Here’s how:
Air conditioners filter out dust, pollen, and other allergens, which can help reduce the number of irritants in the air. This can be especially beneficial for people with hay fever or seasonal allergies, who often find their symptoms worsen during high pollen seasons. A well-maintained AC unit with a high-quality filter can help improve indoor air quality.
Heat and humidity can worsen asthma symptoms, triggering attacks or making breathing more difficult. Air conditioning can help regulate temperature and humidity, creating a more stable and comfortable environment. Maintaining cooler and drier air can prevent the growth of mould, dust mites, and other allergens that thrive in warm, humid conditions.
During allergy season, being outside exposes you to pollen, dust, and other allergens. Air conditioning allows you to stay indoors with filtered air, reducing your exposure to outdoor irritants. This is particularly important for people with asthma, who may find that even moderate levels of outdoor pollutants can trigger an attack.
While air conditioning can provide relief, it’s not without its potential drawbacks. Poorly maintained systems or improper usage can exacerbate allergy and asthma symptoms.
If air conditioning systems aren’t regularly cleaned and maintained, they can become breeding grounds for mold, bacteria, and dust. These contaminants can circulate throughout the air, making things worse for people with respiratory conditions. Mould spores, in particular, can trigger asthma attacks and allergic reactions.
Tip: Regularly clean and replace the filters in your AC unit, and consider having the ducts professionally cleaned if you suspect a buildup of dust or mold. Also, use a dehumidifier if necessary to keep humidity levels low.
Air conditioners can dry out the air, which may irritate the nasal passages, throat, and lungs, especially for asthma sufferers. Dry air can make breathing feel uncomfortable and increase the risk of respiratory infections.
Tip: Use a humidifier alongside your AC to maintain a balanced humidity level. This will help prevent your respiratory system from becoming too dry while still enjoying the cooling benefits of your air conditioning.
Closed windows and poor airflow can lead to a buildup of indoor air pollutants, including volatile organic compounds (VOCs) from household products, pets and cigarette smoke. When the air is stagnant, these pollutants can concentrate, making it harder for people with asthma or allergies to breathe.
Tip: Ensure your home is properly ventilated, even when using air conditioning. Open windows when possible or use an air exchange system to improve airflow.
To maximize the benefits of your air conditioning while minimizing the risks, consider these simple yet effective practices:
High-Efficiency Particulate Air (HEPA) filters are designed to trap microscopic allergens like dust, pollen, and pet dander. By upgrading to a HEPA filter for your air conditioning unit or using standalone air purifiers in your home, you can significantly improve air quality.
Regularly change or clean your air conditioner’s filter according to the manufacturer’s instructions. You should also clean the evaporator and condenser coils, as well as the drain pan, to prevent mould and bacteria buildup.
Try to keep your indoor temperature between 20°C to 22°C. Extremely cold air can aggravate asthma symptoms, so it's best to avoid setting your AC to an overly low temperature. Keeping it at a moderate level will help manage both comfort and respiratory health.
Aim for indoor humidity levels between 40-60%. Too much humidity promotes the growth of mold and dust mites, while too little can irritate the respiratory system. You can use a hygrometer to measure humidity and adjust accordingly with a humidifier or dehumidifier.
Even with an AC system in place, it’s important to monitor other allergens in your home. Wash bedding frequently, vacuum carpets with a HEPA filter vacuum, and keep pets out of bedrooms to minimise buildup. Also, avoid smoking indoors, as secondhand smoke can exacerbate asthma and allergies.
While air conditioning can provide significant relief from heat and humidity, it’s important to use it properly when managing allergies and asthma. Clean and well-maintained air conditioning systems can help filter out allergens, reduce exposure to outdoor irritants, and regulate indoor temperature and humidity. However, if neglected, air conditioners can also contribute to respiratory issues by circulating dust, mould, and dry air.
By following the right practices—such as using HEPA filters, maintaining proper humidity levels, and keeping your AC unit clean—you can enjoy the cooling comfort of air conditioning while minimising its potential impact on your health. If you have specific concerns, consult your healthcare provider or an allergy specialist for tailored advice.
We’ve all been there. It’s a blistering hot summer day, you’ve got a cold drink in hand, your favourite show queued up, and you just settled into the couch... when suddenly, your air conditioner throws a tantrum. The room gets warmer, the air turns sticky, and the only thing colder than your attitude is the ice cream melting in your bowl.
But before you resort to yelling at your air conditioner (because let's be honest, we’ve all done it), let’s take a moment to understand why our cooling buddies have such a short fuse. Air conditioners can be picky, and they demand a little TLC to keep them from acting out. So, before your A/C locks itself in the "OFF" position, here’s how to keep it in a good mood and working like a charm.
Imagine if you never took a shower and then had to run a marathon. Yeah, that's what it’s like for your A/C when you don’t clean its filters regularly. Air conditioners have a filter that needs cleaning about once a month, especially during peak usage times. When filters get clogged with dust and dirt, airflow gets restricted, and your A/C has to work harder to cool the room. It starts to overheat, and before you know it, it's throwing a tantrum and shutting down on you.
Tip: Remove the filter and clean it with warm water and mild soap. Let it dry completely before replacing it. Pro tip: If you have pets, clean the filter more often—your A/C doesn’t need your cat's fur as an extra insulation layer.
You wouldn’t expect your A/C to cool your whole block, right? But sometimes, we try to make it do just that. Overworking your air conditioner by setting the temperature too low or running it all day long in a space that’s too large can lead to overheating or, worse, a total breakdown.
Tip: Set your thermostat to a reasonable temperature (around 75°F is ideal). If you’re not home, don’t make your A/C work for no reason—set it to 78°F while you’re out. Your wallet and your A/C will thank you.
Just like you need a break from Netflix binges, your air conditioner needs a little rest, too. Running it continuously without giving it some downtime can wear out its internal components. Think of your A/C like a workaholic employee—you need to give it some time off, or it’ll get grumpy.
Tip: If you're home, open a window and let some fresh air in to cool things off for a little while. If you're working from home, don’t keep it cranked up all day. Schedule breaks when the outside temperature is cooler.
The condenser coils and evaporator coils inside your air conditioner are like its lungs—if they’re dirty, your A/C can’t breathe properly, and it’ll start to overheat. Just like you can’t function well when you’re choking on dust bunnies, your A/C can’t do its job properly if it's covered in grime.
Tip: Take a quick peek at the coils and make sure they aren’t caked in dirt. You can use a soft brush or vacuum with a brush attachment to clean the coils. But, if you're not sure how to do this safely, calling a pro might be your best bet.
Just like we seek out the shade during a heatwave, your A/C also appreciates being kept cool. If your unit is sitting directly in the sun, it has to work harder to cool the air. Plus, prolonged exposure to sunlight can cause wear and tear on the unit, leading to breakdowns when you need it most.
Tip: If possible, place your unit in a shaded area, or use a sunshade to block direct sunlight. The less your A/C has to fight the sun, the better it will work.
Air conditioners hate indecision. Don’t constantly adjust the thermostat. When you keep switching the temperature by 5 degrees every hour, you’re just confusing your A/C. It’s like trying to follow a GPS that keeps changing directions.
Tip: Pick a temperature and stick with it. The more consistent you are, the better your A/C will perform. Plus, you won’t keep your A/C in "I’m not sure what you want from me" mode.
It’s tempting to rearrange furniture, but if you’ve placed a sofa right in front of the air vents, you’re basically asking your A/C to cool your house through a wall of fabric and cushions. A/Cs need clear airflow to function efficiently. Blocked vents mean it’s trying to cool a room with less air, which can cause stress and overheating.
Tip: Ensure all vents are unobstructed, and if you’ve got furniture or curtains in the way, move them. Your A/C needs to breathe just like you do!
Just like your car, your air conditioner benefits from a little maintenance now and then. Regular inspections by an HVAC professional can help catch minor problems before they turn into full-blown meltdowns.
Tip: Hire an HVAC technician to give your A/C a check-up once or twice a year. It’s like sending your A/C on a spa day, and it’ll thank you by working longer without drama.
If your air conditioner starts making weird noises, it’s like your pet scratching at the door—you need to pay attention. Unusual sounds might be a sign of a mechanical issue or a buildup of debris, and ignoring them could lead to bigger, more expensive problems down the line.
Tip: If your A/C is rattling, buzzing, or hissing, call a technician. The sooner you address the issue, the less likely your A/C is to pull a dramatic meltdown on a hot day.
If you’ve ever had your air conditioner quit on you mid-summer, you know the frustration is real. But don’t let your A/C become a diva—treat it with care, respect, and regular maintenance, and it’ll be your cool, calm, collected partner through the hottest months of the year. By following these tips, you’ll not only prevent your air conditioner from throwing a tantrum, but you’ll also extend its lifespan and enjoy a cooler, happier home all summer long.
Now, go give your A/C a little TLC ❄️

Air conditioning is often seen as a luxury during hot summer months, or as a tool to maintain comfort in the colder weather. However, its benefits go far beyond just keeping us cool or warm. Whether in a home, office, or commercial space, air conditioning (AC) plays a crucial role in improving health, productivity, and overall well-being. Here, we explore the various benefits of air conditioning beyond just regulating temperature.
Air conditioning units come equipped with filters that can capture dust, pollen, and other airborne particles. This helps improve indoor air quality by removing allergens and pollutants that can lead to respiratory issues, asthma, or allergies. Clean air promotes better lung health and makes breathing easier, particularly for people with pre-existing conditions.
Modern air conditioning systems even include high-efficiency particulate air (HEPA) filters or ionizers that can trap bacteria and viruses, reducing the presence of harmful pathogens in indoor environments. This feature is especially important in public spaces like offices, schools, and healthcare facilities, where maintaining clean air is vital to reducing the spread of illnesses.
Extreme temperatures can be distracting and uncomfortable, affecting your concentration and productivity. Whether you're working from home, studying, or running a business, a consistent, comfortable environment is essential for performance. Air conditioning helps to maintain an optimal indoor climate, making it easier to focus and perform tasks efficiently.
In workplaces, especially those with electronic equipment that generates heat (like servers or computers), air conditioning also prevents overheating, ensuring that both people and machines can function optimally without interruptions.
Humidity is a key factor in overall comfort and well-being. High humidity can make the air feel sticky, uncomfortable, and oppressive, while also creating an environment conducive to mold and mildew growth. Excess moisture in the air can damage furniture, electronics, and fabrics, as well as cause structural damage over time.
Air conditioners help to regulate humidity levels by removing excess moisture from the air, ensuring a more comfortable and healthier indoor environment. By maintaining balanced humidity, air conditioning helps protect both your home and your health.
It’s no secret that temperature plays a major role in sleep quality. When it’s too hot, falling asleep can be difficult, and staying asleep even more so. The discomfort of overheating can lead to restless nights and poor-quality sleep.
Air conditioning helps to maintain a cool, comfortable sleeping environment, which can improve both the quality and quantity of sleep. Studies show that cooler rooms promote deeper, more restful sleep, reducing the chances of waking up in the middle of the night or experiencing disturbed sleep cycles.

Most electronic devices, such as computers, smartphones, and TVs, generate heat while in use. Over time, exposure to excessive heat can damage internal components and shorten their lifespan. Air conditioning helps mitigate the risk of overheating by maintaining a consistent temperature, thereby protecting your valuable gadgets from potential damage and ensuring they perform optimally.
In businesses and data centers, air conditioning is especially critical. Server rooms filled with sensitive equipment require precise temperature and humidity control to prevent failures, downtime, or data loss. AC units are essential for keeping this equipment safe and running smoothly.
While outdoor environments can be noisy due to traffic, construction, or weather conditions, air conditioning units provide a steady white noise that can help mask these sounds. This can be particularly beneficial in urban areas, where external noise pollution can interfere with concentration, relaxation, and even sleep.
By dampening disruptive external noises, air conditioning creates a quieter, more serene indoor environment. This is especially important in offices, homes, and healthcare facilities where maintaining a calm atmosphere is key to productivity and mental well-being.
Humidity and fluctuating temperatures can take a toll on furniture, artwork, books, and other valuable items in your home. Wood furniture can warp or crack, paintings may fade, and books or documents could get damaged by moisture. Air conditioning helps to maintain a stable indoor environment, which protects these items from the harmful effects of humidity and heat.
In addition to protecting physical items, AC can also prevent the growth of mold and mildew, which thrive in warm, damp conditions. By keeping the indoor air dry and cool, air conditioning extends the lifespan of your belongings.
Prolonged exposure to extreme heat can cause dehydration, heatstroke, and other serious health issues. For vulnerable populations, such as the elderly, children, or people with pre-existing medical conditions, heat can be particularly dangerous. Air conditioning helps reduce the risk of heat-related illnesses by maintaining a safe and consistent temperature indoors.
By keeping temperatures under control, AC not only provides comfort but also helps protect your health during hot weather.
The comfort provided by air conditioning contributes to better mental health. Extreme heat can lead to irritability, stress, and fatigue, making it difficult to concentrate and remain positive. When you’re comfortable in your environment, it’s easier to relax, enjoy time with loved ones, or focus on your work.
Air conditioning can help reduce stress levels by providing a comfortable and controlled environment, which has a direct impact on emotional well-being. For individuals living in areas with high heat and humidity, AC can be a crucial factor in maintaining a calm and peaceful atmosphere at home.
Homes and properties with installed air conditioning systems are more attractive to buyers, especially in regions where temperatures rise during summer months. The presence of AC can increase the resale value of your home, making it a smart investment for homeowners looking to enhance the appeal and functionality of their property.
Additionally, as people become more aware of the long-term health and comfort benefits of air conditioning, homes with efficient, modern AC systems may become even more desirable in the future.
Air conditioning is much more than just a tool for controlling temperature. It plays an essential role in enhancing air quality, boosting productivity, regulating humidity, and improving health and comfort. Whether you're seeking relief from allergies, a better night's sleep, or a more productive workspace, the benefits of air conditioning extend far beyond mere cooling.
Investing in a quality air conditioning system can improve your quality of life in many ways, making your home or business a more comfortable, safe, and enjoyable place to be. So next time you enjoy the cool comfort of an AC unit, remember that it’s doing far more than just keeping you comfortable—it’s actively contributing to your health, well-being, and peace of mind.
Air conditioning systems are essential for keeping your home cool and comfortable, especially during the hot summer months. However, like all appliances, they don’t last forever. Over time, even the best AC units can show signs of wear and tear. So, how do you know when it’s time to upgrade your air conditioning system?
Here’s a guide to help you determine when it’s the right time to invest in a new AC unit.
The average lifespan of an air conditioning unit is between 10 to 15 years. If your AC unit is approaching or has surpassed this age range, it may be time for a replacement. As your AC ages, it becomes less efficient, and parts may start to wear out or break down more frequently.
Modern systems are far more energy-efficient than older models, so upgrading to a new system can save you money on utility bills and reduce your environmental impact. Additionally, newer units are often quieter and more reliable.
If you find yourself calling a repair technician more than once a year, it’s a red flag. Frequent repairs not only become costly but also signal that your AC is nearing the end of its useful life. Repairing an old system over and over may not be the most cost-effective solution in the long run.
Consider this: if the cost of repairs in a year exceeds 50% of the price of a new system, it’s likely time to replace it. Continuous breakdowns also leave you without cooling at the worst times, making the upgrade worthwhile for long-term peace of mind.
One of the most obvious signs that your air conditioner is no longer operating efficiently is a significant increase in your energy bills. Older units are often less energy-efficient, meaning they consume more electricity to achieve the same level of cooling. Modern air conditioners, especially those with the ENERGY STAR label, are designed to be far more efficient, saving you money on your monthly utility costs.
If your energy bills have been creeping up over the years, despite the same usage patterns, this could indicate that your AC is struggling to keep up, and it may be time for an upgrade.
Is your home always warm, even though your air conditioner is running? Uneven cooling is a sign that your AC isn’t functioning properly. It could be due to issues with refrigerant levels, a clogged air filter, or a malfunctioning compressor. While some of these issues may be repairable, if the problem persists or worsens over time, you might need to replace the entire unit.
Similarly, if you notice poor airflow in certain areas of your home, this could be a sign that your AC system isn’t operating at full capacity. A replacement could address the issue and help maintain consistent comfort throughout your home.
Your air conditioner should run relatively quietly, with just the normal hum of the fan and compressor. If your AC is making strange noises, such as grinding, rattling, or buzzing sounds, it’s a signal that there could be a major internal issue. In some cases, these noises can be fixed with a repair, but if they are persistent or caused by worn-out parts, it may indicate that the unit is nearing the end of its life.
Similarly, if your air conditioner is emitting unpleasant odors like mold, mildew, or burning smells, it could point to electrical issues, mold buildup, or a malfunctioning motor. These smells can also indicate the need for a replacement, especially if they persist after cleaning or minor repairs.
Refrigerant is the substance responsible for cooling the air in your AC system. If your system is leaking refrigerant, it will struggle to cool your home effectively. In the past, refrigerant was commonly used in AC units, but modern systems often use more eco-friendly alternatives.
If your AC system is low on refrigerant, it’s possible to refill it, but leaks are a major concern. If your unit is older and leaks refrigerant frequently, it could be a sign of serious internal damage. Repairing a refrigerant leak can be expensive, and in some cases, it may not even be possible. Upgrading to a new system that’s more efficient and eco-friendly is often the best solution.
If your air conditioning unit uses R-22 refrigerant (also known as Freon), it’s time to start thinking about an upgrade. R-22 was phased out in 2020 due to its harmful environmental impact, and it is no longer produced in the United States. While it’s still possible to find R-22 refrigerant, it is becoming increasingly expensive and difficult to obtain.
If your system is still running on R-22, it’s a sign that your AC is outdated and should be replaced with a newer, more eco-friendly model that uses R-410A or another environmentally safe refrigerant.
Air conditioners do more than just cool your home—they help filter and circulate air. If you’re noticing an increase in dust, pollen, or other allergens in your home, it could be a sign that your AC system is no longer doing its job properly. Old air conditioners may have clogged filters, inefficient air purifiers, or other components that hinder their ability to provide clean, fresh air.
If you've been noticing more allergies or respiratory issues at home, upgrading to a newer model can help improve your indoor air quality.
If you're preparing to sell your home, a new AC system can increase its value and appeal to potential buyers. Buyers are often looking for homes with modern, energy-efficient appliances, including air conditioning systems. A new AC unit can be an attractive selling point and may help you command a higher price for your home.
An air conditioning system is a major investment, but when it begins showing signs of wear, inefficiency, or breakdowns, it’s important to consider upgrading. Replacing an outdated, inefficient AC system with a new, energy-efficient one will save you money on repairs and utility bills, improve your home’s comfort, and give you peace of mind for years to come.
If you’re experiencing any of the issues mentioned above, it may be time to contact a HVAC professional for an assessment and explore your options for upgrading your air conditioning system. ❄️
Air conditioning (AC) is a technology typically associated with hot climates, and in the past, it was often seen as a luxury in the UK, where cooler, temperate weather dominated the majority of the year. However, in recent years, the demand for air conditioning in the UK has surged, marking a significant shift in how residents and businesses approach indoor comfort. This growing trend is not just about coping with the occasional heatwave; it reflects a broader change in climate patterns and lifestyle choices. Let's explore the factors driving this demand and what it means for the future of air conditioning in the UK.
The most obvious driver behind the rise in demand for air conditioning in the UK is the changing climate. Over the past few decades, the UK has seen a noticeable increase in the frequency and intensity of heatwaves. According to the UK Met Office, the country is experiencing more days with temperatures exceeding 30°C (86°F), and such occurrences are predicted to become more common in the future due to global warming.
In 2019, the UK recorded its hottest-ever summer, with the temperature reaching 38.7°C (101.7°F) in Cambridge. This marked a turning point in the way the public and businesses viewed the need for cooling solutions. What was once an occasional inconvenience during a hot spell has now become a growing concern as the heatwaves seem to be getting longer and more intense.
Urban areas, particularly large cities like London, Birmingham, and Manchester, experience what is known as the “urban heat island” effect. This phenomenon occurs when concrete, asphalt, and other man-made materials absorb and retain heat, making cities significantly hotter than surrounding rural areas. As urbanization increases, the demand for cooling solutions becomes even more critical in these environments.
The urban heat island effect is a double-edged sword: it not only drives up the temperature but also exacerbates the environmental impact of air conditioning, as buildings and infrastructure require more energy to stay cool. As a result, there's been a push to adopt more sustainable cooling technologies, but the need for air conditioning in cities is undeniable, particularly during peak summer months.
The way people live and work is also contributing to the rising demand for air conditioning in the UK. A few decades ago, it was common for homes to be designed with natural ventilation in mind, relying on the cool British breeze to maintain comfort. However, the trend towards modern, energy-efficient buildings with sealed windows and more compact living spaces has made it harder for people to cool their homes without mechanical assistance.
Moreover, as working from home becomes more common, people spend more time indoors, which means they are more likely to seek cooling solutions when the weather turns sweltering. AC units are no longer just a luxury for large offices or retail spaces—they are becoming an essential part of home comfort, especially as remote work continues to grow in popularity.
Another factor contributing to the rise in air conditioning demand is the growing awareness of the health risks associated with extreme heat. In 2022, a report by Public Health England warned that rising temperatures could lead to more heat-related illnesses, particularly among vulnerable groups such as the elderly, children, and those with pre-existing health conditions.
Prolonged exposure to high temperatures can cause dehydration, heatstroke, and cardiovascular strain, and in extreme cases, can be fatal. As heatwaves become more common, the need to protect the most vulnerable members of society has led to a growing demand for air conditioning, both in homes and in public spaces like hospitals, care homes, and schools.
Historically, the upfront cost and installation process of air conditioning units deterred many UK residents from investing in them. However, recent advancements in AC technology, along with a decrease in installation costs, have made air conditioning more accessible to a wider range of people. Newer models are more energy-efficient and environmentally friendly, helping to address concerns about both energy bills and carbon footprints.
In addition, with the rise of smart home technologies, air conditioning systems have become more convenient to use. Many systems can now be controlled remotely through mobile apps, allowing users to pre-cool their homes before they arrive or adjust settings on the go. This convenience, combined with improved energy efficiency, makes air conditioning more appealing to a broader audience.
It’s not just residential homes that are driving the demand for air conditioning. Businesses, too, are recognizing the need to maintain a comfortable working environment for employees and customers. Retailers, office buildings, and hospitality venues rely on AC systems to ensure a pleasant atmosphere during peak summer periods. In competitive sectors, offering a comfortable working or shopping environment can be a key differentiator.
For businesses that operate in industries where precision climate control is essential—such as data centers, laboratories, or manufacturing plants—air conditioning is not a luxury but a necessity. As such, commercial demand for air conditioning is also on the rise, pushing the industry to innovate and offer solutions tailored to a variety of business needs.
Despite the growing demand for air conditioning, the environmental impact of cooling systems remains a significant concern. Traditional AC units rely heavily on refrigerants, some of which are potent greenhouse gases. Additionally, the energy required to power AC systems can contribute to higher carbon emissions if the electricity is sourced from fossil fuels.
However, there is increasing pressure on manufacturers to develop more sustainable air conditioning solutions. Some companies are focusing on using natural refrigerants or improving the energy efficiency of their units. Solar-powered air conditioning and the integration of renewable energy sources are also gaining traction as ways to reduce the environmental footprint of cooling systems.
As the demand for air conditioning continues to rise in the UK, it is clear that the country is adjusting to the reality of hotter, longer summers and more frequent heatwaves. The growing need for comfort, health protection, and productivity in the face of extreme weather is pushing air conditioning from a luxury to a necessity for many households and businesses.
At the same time, the push for sustainability and energy efficiency will likely drive innovation in the industry. As the UK continues to grapple with climate change and adapt to new weather patterns, it’s clear that air conditioning will play an increasingly important role in shaping how we live, work, and stay healthy in a warming world.
As the demand grows, it will be interesting to see how both technological advancements and societal shifts influence the way the UK cools down in the years to come. ❄️
Whether it's summer or winter, the last thing anyone wants is to deal with a malfunctioning air conditioning system. One common issue that people face is their air conditioning systems leaking. Whether it’s water pooling around your unit or refrigerant leaks causing performance issues, understanding the root causes of leaks can help you avoid further damage and costly repairs. Here are some common reasons why your air conditioning system might be leaking:
1. Clogged or Dirty Condensate Drain Line
Air conditioners work by removing moisture from the air to cool your home. This moisture is collected in the form of condensate, which should then flow through the drain line and out of the unit. Over time, dirt, dust, mold, and algae can clog the condensate line, preventing the water from draining properly. This can cause water to back up and leak inside or around the unit.
Solution: Regular maintenance and cleaning of the condensate drain line can prevent clogs. If you’re unsure how to clean the drain line, a professional HVAC technician can help clear it to restore proper water flow.
2. Frozen Evaporator Coils
The evaporator coils inside your air conditioner absorb heat from the air, but if the coils freeze up due to airflow problems or low refrigerant levels, they can thaw and cause excess water to drip. This happens because the ice melts and overflows the condensate drain.
Solution: Check for signs of frozen coils, such as poor cooling performance or frost buildup on the coils. A blocked air filter or low refrigerant could be the culprits. Make sure your filters are clean, and contact an HVAC technician to check refrigerant levels and fix any underlying issues.
3. Low Refrigerant Levels
Refrigerant is responsible for absorbing and transferring heat from your home. If the refrigerant level is low due to a leak in the system, it can cause the evaporator coils to freeze, which in turn leads to excess water when the ice melts. Low refrigerant not only causes leaks but can also damage your air conditioner if left unresolved.
Solution: Low refrigerant typically signals a leak, and fixing this issue requires a professional HVAC technician. They can locate and repair the leak, then recharge the system with the proper amount of refrigerant.
4. Damaged or Broken Pump
Some air conditioning systems come equipped with a condensate pump that helps remove excess water from the unit. If this pump malfunctions or becomes damaged, water may back up and start leaking around your unit.
Solution: If you suspect the pump is faulty, it’s best to contact an HVAC professional who can inspect and replace the pump if necessary.
5. Improper Installation or Sizing
If your air conditioning unit was not properly installed or is the wrong size for your space, it can struggle to perform efficiently. An oversized or undersized unit can lead to moisture issues, including leaks.
Solution: If you’ve noticed persistent leaking issues after installation, it may be worth having your system assessed by an HVAC professional. Proper installation and sizing can improve performance and prevent long-term problems.
6. Leaky Ductwork
In some cases, air conditioning systems may experience leaks due to issues with ductwork. If ducts are damaged or improperly sealed, condensation can accumulate and leak out. This is particularly true in the case of ducts that pass through attics or unconditioned spaces, where temperature differences can lead to condensation buildup.
Solution: Inspecting and sealing ducts is a job best left to a professional. Proper insulation and sealing of ducts can prevent condensation and potential leaks.
7. Aging or Worn-out Components
As air conditioning systems age, parts can wear down, causing issues like leaks. Older units may experience corrosion in the coils, drain pan, or other components, which can lead to water leakage.
Solution: Regular maintenance can help spot signs of wear before they turn into significant problems. If your unit is approaching the end of its lifespan, you may want to consider replacing it to avoid ongoing repairs.
Air conditioning systems can develop leaks for several reasons, ranging from simple issues like clogged drain lines to more complex problems like refrigerant leaks. Regular maintenance and prompt attention to any issues can help you avoid costly repairs and keep your system running efficiently. If you’re experiencing leaks or other problems with your air conditioning system, it’s best to consult a professional HVAC technician to diagnose and resolve the issue before it leads to more serious damage.
Stay cool and comfortable—address air conditioning leaks as soon as you notice them! ❄️
For many years air conditioning in a home, or even a small office, was regarded as an unnecessary expense or luxury item. However, these days air conditioning is the norm and is becoming more and more popular each year that passes.
Many people looking to purchase a home or business premises may find a building with an existing air conditioning installation, that both heats and cools all year round, very attractive.
With the Governments push to try to move away from the use of gas for our space heating and hot water, a house with an alternative heating source may give potential purchasers peace of mind that they are already prepared for any changes in legislation that might arise in the future.
One of the main attractive features about an air conditioning installation in a property, is that they provide a much cheaper alternative to heating than gas does. Knowing that they will save on energy bills throughout the winter months could be a huge bonus for potential buyers.
Don't forget though, the installation of any air conditioning or air source heat pump system, must be installed by an F-Gas certified engineer. Keep all the relevant commissioning and service certificates (or ask your installer for them) if you are wanting to sell your property.
So, if you have a professionally installed air conditioning system in your premises, there are many different reasons as to why this can make your home much more attractive to potential buyers!
When you hear the words air conditioning you may think of walking out of the hot sun into a nice cool environment, such as a hotel room or supermarket, but more and more people are starting to also realise the amazing heating benefits they provide. In fact, we and many others actually find the heating side of the system even more impressive that the cooling side.
Heat Pump
Almost all modern air conditioning systems now use a piece of technology known as a heat pump. This technology allows the system to reverse the cooling process and heat a room(s) as well as cool. There are various types of heat pumps on the market but the most common ones are the following:
- Air to water heat pumps
These systems tend to only provide heating although some manufacturers have systems that can also cool. These systems work by absorbing heat from the ambient air and transferring that heat into water. This water is then typically used for heating a building via heat emitting devices such as radiators or underfloor heating. An air to water heat pump will heat stored water within a cylinder which can then be used for showers and baths etc.
- Ground source heat pumps
Rather than absorbing heat from the air a ground source heat pump utilizes the thermal energy within the ground and then transfers it to the water in the same way an air to water heat pump does. These systems can also provide cooling in the summer.
- Air to air heat pumps
Air to air heat pumps are typically air conditioning systems. They absorb heat from the outside air and transfer this to a fan coil unit within a building which is then used to heat the room(s). Typically smaller systems do not heat stored water although some manufactures have larger systems that have the option to add this feature.
How does it work?
Reversing valve
The reversing valve is the main component within an air to air heat pump that allows the system to heat and it works by reversing the flow of the refrigerant.
When in cooling mode the job of the system is to absorb heat from a warm room and as the refrigerant is pumped through the evaporator (the indoor unit), it collects the heat from the air that is being pulled over the evaporator coil via a fan. Then as the refrigerant leaves the evaporator and starts its journey back to the compressor (which is situated within the outdoor unit) it is now carrying lots of heat.
The compressor will then pump the refrigerant to the condenser coil which will also have a fan that helps cool the refrigerant of the heat it has collected and the cycle continues until enough heat has been removed from the room.
When in heating mode the reversing valve diverts the flow of refrigerant in the opposite direction which enables the outdoor unit condensing coil to now absorb heat from outside (taking on the job of the evaporator in cooling mode). The compressor then pumps the heat filled refrigerant to the indoor unit coil (which now becomes the condenser) whilst the fan pulls the air over the coil where it picks up the heat. Again this cycle continues until the room has reached the desired temperature.
Pros of heat pumps over traditional forms of heating
- Energy efficiency
Whether air to air, air to water, or ground source you should expect the system to be much cheaper to run than traditional gas, oil and certainly electric heaters. A modern gas boiler typically runs at around 90% efficiency, older boilers much lower. A good quality heat pump will run at between 300% and 400% efficiency meaning it is a much cheaper method of keeping your home warm in the winter.
- Grants / VAT exemptions
There has been a huge push recently on the use of renewable energy and to help people struggling with the cost of living crisis, the government have expressed their desire to move away from the use of fossil fuels such as gas and in an attempt to encourage this they have put in place various grants and VAT exemptions to help with the cost of installing these systems.
- Contributing to a more sustainable society
Many people who own businesses and homes feel they want to “do their bit” and play a part in trying to combat climate change and help provide a better future. Lots of businesses like to showcase their attempts at running a “greener” business and homeowners also benefit from this and should expect the value of their home to increase and become more attractive to potential buyers in the future.
- Cool environment in the summer
The obvious advantage to a heat pump (specifically air to air heat pump) is that it will also provide cooling in the summer, this enables you to have the perfect temperature all year round.
Cons of heat pumps
- Installation costs
Although much cheaper to run than traditional heating methods heat pumps are typically more expensive to install than gas boilers.
- Disruption
With an air to air heat pump disruption to existing property and services is usually minimal, however an air to water or ground source installation may involve more disruption than the typical gas boiler installation. Often on retrofit installs radiators and existing pipe sizes may need to be increased which can often cause disruption.
- Labour shortages
Although heat pumps have been around a number of years, when it comes to air to water and ground source there is a still a shortage of engineers when compared to gas and heating engineers. However this is not the case with air to air heat pump (air conditioning) engineers.
Summary
When it comes to air source heat pumps, whether air to air, air to water, or ground source, they appear to be here to stay and are the future of heating/cooling in this country. Summers are becoming hotter, winters are becoming colder, and awareness on climate change is increasing and the cost of fossil fuels continues to rise, so it is in no doubt that heat pumps will become more and more popular.
Many countries around Europe have embraced heat pumps and are much further ahead than the UK, but it does look like we are looking set to follow.
It's important to do your research when considering a heat pump and ensure the company you consider has all the knowledge required to provide you with the best system for both yourself and for your properties needs .
These systems are installed high up on a wall inside your room. They can be installed on an internal or external wall. Wall mounted units are typically the most affordable, and least disruptive, systems to install - especially if installed on an external wall.
There are now many different designs available on the market to suit your requirements and preferences from the classic white systems to the prestigious Mitsubishi Electric Zen, LN or Toshiba Hoari systems, which come in a range of colours!
Wall mounted systems typically range from 1.5kw to 12.5kw (brand and range dependent) so they are suitable for most sized rooms within a home or business.
Many systems come with additional features such as wifi compatibility, allergen filters, sophisticated louvres enabling you to control the direction of the air and weekly or daily timer settings.
All systems come with option to cool and heat and they also have a dehumidify option!
Some systems come with additional features, such as the below:
- plasma quad filters - these eliminate 99% of air-born viruses, bacteria and mould, 98% of allergens such as pollen and also 97% of mites and dust.
- Sensors which monitor room occupancy and body temperatures to help achieve the most comfortable temperature.
Have you ever wondered how air conditioning works?
Here is a simple explanation of the process!
Air conditioning works by removing heat from the air within a space. This is done through a process that involved a refrigerant, which absorbs heat and then releases it elsewhere.
The refrigerant travels through the refrigeration cycle, from the compressor that is usually situated in the outdoor unit. The refrigerant is pumped through a condenser coil (also known as a heat exchanger) to remove unwanted heat. Then the refrigerant travels through pipes that are connected to an indoor unit (also known as an evaporator). The indoor unit also has a coil and a fan within the unit, which pulls air into the system and over the coils. The refrigerant running through the pipes inside the coil, absorbs heat from the air. This air is blown out of the system, back into the room, at a much cooler temperature.
The refrigerant carrying the heat from the space then travels back to the outdoor unit condenser coil via the pipework where it releases the heat absorbed by the refrigerant into the outside air. This process continues until the desired temperature is reached. ❄️🏠
Below is a more detailed explanation on what each component of an air conditioning system does.
The different components of an air conditioning system
Evaporator
The evaporator plays a crucial role in the cooling process of an air conditioning system . It is typically located inside the indoor unit of the system and works by absorbing heat from the air inside the room.
The evaporator, in essence, is a long coil of pipe that has a flowing refrigerant passing through it that is at a low pressure and low temperature. When warm air from the room passes over the coil, the refrigerant absorbs the heat from the air, causing it to evaporate into a vapour. This cools the air and removes the moisture, creating a more comfortable indoor environment.
Overall, the evaporator is responsible for cooling and dehumidifying the air in an air conditioning system, making it a crucial component for maintaining a comfortable indoor climate.
Compressor
The compressor for an air conditioning system is typically located in the outdoor unit. It is responsible for the circulation of refrigerant around the system when the refrigerant leaves the evaporator. It is pulled into the compressor where it is then compressed, which increases the pressure and temperature. It is then pumped out of the compressor to the condenser.
Condenser
The condenser is also typically located in the outdoor unit of an air conditioning system and is responsible for releasing heat from the refrigerant gas to the outside environment. By releasing heat to the outside environment, the condenser helps to cool down the refrigerant and prepare it to absorb heat from the indoor air in the evaporator. This process allows the air conditioning system to effectively remove heat from the indoor space and maintain a comfortable temperature.
Expansion Valve
The expansion valve plays a key role in controlling the flow of refrigerant and regulating the pressure and temperature of the refrigerant as it moves through the system. It is typically located between the condenser and the evaporator . It's primary function is to create a pressure drop in the refrigerant, which causes the refrigerant to expand and evaporate into a low-pressure, low-temperature gas. This process allows the refrigerant to absorb heat from the indoor air in the evaporator, cooling the air and removing moisture.
A common belief with air conditioning is that it brings in fresh air from the outside - what if we were to tell you that this is actually false?
What air conditioning actually does is exactly what the name suggests - it "conditions the air".
Air conditioning works by taking away unwanted heat from a space and transfers that heat elsewhere. This heat is carried away via the refrigerant that is cycling through the system. It is not bringing in cold air from the outside, it is merely removing the heat from the air already in the room.
If having fresh air and ventilation is a priority to our customers then we suggest that they have a simple supply fan, which does pump fresh air in from outside. Or there are more sophisticated mechanical ventilation heat recovery systems that are available on the market.
These heat recovery systems will bring in fresh air from the outside, whilst also extracting waste air from within the room. During the winter months when the heating is on, rather than force the heating to work harder by forcing fresh, cold air inside, the heat from the waste air can be extracted and used to heat the new fresh air back up. This way the heat is recovered from the waste air making it a very efficient process and prevents any unnecessary waste!
A question we get asked a lot during the summer months...which is better, portable or fixed air conditioning?
The answer depends on each individuals needs and if it is a question you are currently asking yourself, then hopefully the following will help you.
Portable Air Conditioning
About
A portable air conditioning system is a compact unit that can easily be moved around from room to room without the need for any permanent installation, or an air conditioning specialist.
It uses the same technology as a fixed AC system by absorbing heat from the air and expelling it outside (please see our "How Does Air Conditioning Work" article for more information on this).
The portable systems usually sit on the floor and has an extendable flexible duct that can be hung out of an open window for the heat to escape.

Fixed Air Conditioning
About
Although fixed air conditioning can be removed and reinstalled elsewhere, this is usually costly and can be disruptive, which is why these systems are considered a permanent installation (the clue is in the name!)
Unlike portable air conditioning systems, fixed systems have more components and require a certified F-Gas engineer to carry out the installation with the specialist tools and equipment needed.
Fixed air conditioning systems require an indoor fan unit and an outdoor fan unit to be installed, and they have a pipe and cable which interconnects the two parts (unlike portable air conditioning which is an all in one system).

How often does my air conditioning need "re-gassing"?
A common misconception is that air conditioning units need regular re-gassing when a service takes place. We get many customers asking us why we haven't "re-gassed" their systems during a service.
You may find you are re-gassing the air conditioning in your car annually before the summer months and assume the same is necessary for a fixed air conditioning system.
Although there are occasions when an air conditioning system may need re-gassing, generally you should expect a system to last the duration of its running life without the need to be re-gassed.
It is important that your air conditioning installation is carried out by an experienced and competent engineer. Please also ensure that the engineer, or company, holds an F-Gas certification (this allows them to legally and safely handle the refrigerant found within air conditioning systems).
This will ensure that the system is installed correctly and the engineer will have both the knowledge and the tools to carry out all the necessary procedures during the installation - including a pressure/leak test.
What is a pressure/leak test?
Once an engineer has finished an installation they will carry out a pressure test on the system. This involves forcing oxygen-free nitrogen into the system to raise the pressure inside to a higher pressure than the refrigerant inside would ordinarily run at. This helps the engineer be confident that all mechanical and brazed joints are strong enough to hold the pressure and this will not allow a leak to take place.
With all the above considered we can now see how we should expect (if installed correctly) your system to last it's entire lifetime without being re-gassed.
Exceptions
As with everything, there are exceptions, and leaks can occur. If you have a leak on your system, the following is likely to be one of the reasons why:
To summarise, although air conditioning systems shouldn't leak if they have been correctly installed, there are exceptions to this as described above. Regular servicing is the best way to be assured there are no leaks on your systems, and if one is found it can be repaired quickly so there is no disruption to the use of your system.
How much does air conditioning cost to run?
When purchasing air conditioning for your home or business an important thing to consider is the efficiency of the system and how much you can expect it to cost. It would be especially helpful to know how much it would cost to keep it running during the summer months at a temperature to keep you comfortable.
In the UK our summers are pretty unreliable, so the following applies providing we have what we would regard as a "good" summer!
If you are installing air conditioning for the first time then hopefully the following will give you some sort of idea on what to expect regarding running costs.
All manufacturers and types of systems vary slightly but for this example we will take a standard 2.5kw split system (a typical system used in a domestic installation or small office). Typically you can expect this type of system to cost between 10p-40p per hour to run.
