But before we dive in, let’s start with the basics…
What Is An Air Conditioner and How Does It Work?
An air conditioner is an appliance designed to cool and dehumidify the air in your home or workplace. It works by drawing in warm air from the room, passing it over a set of refrigerant-filled coils to remove the heat, and then circulating the cooled air back into the space. This cycle repeats continuously until your desired temperature is reached, keeping you comfortable no matter how hot it gets outside.
Understanding how your system works makes it much easier to spot when something isn’t quite right, which brings us to maintenance…
How To Maintain Your Air Conditioning Unit
How To Maintain Your Air Conditioning Unit
Maintaining your air conditioning unit is one of the most important things you can do to protect your investment and keep your energy bills under control. A neglected system has to work harder, costs more to run, and is far more likely to break down when you need it most. Here are the key maintenance steps to stay on top of:
Clean or replace your air filter regularly. A clogged filter restricts airflow, forces the unit to work harder, and reduces cooling efficiency. We recommend checking it every month and replacing it at least every three months.
Check the condenser coils periodically. Dirty coils can’t transfer heat effectively, which means your system will struggle to cool the air properly. If you’re unsure how to check these yourself, our team are happy to help.
Ensure the unit is properly ventilated. Blocked or restricted airflow around your unit — whether indoors or outdoors — will significantly reduce its performance. Clear any leaves, debris, or obstructions from around the external unit regularly.
Book a professional service every year. Just like a boiler service, an annual check by a qualified engineer keeps your system running efficiently, helps catch small problems before they become expensive ones, and can extend the life of your unit considerably.
Common Air Conditioning Problems and What To Do
Even with good maintenance, issues can arise. Here are the most common call-outs our engineers attend across Birmingham, Tamworth, Solihull, Lichfield, and the rest of the Midlands — and what they usually mean:
AC Not Cooling Properly If your unit is blowing warm or lukewarm air, the most likely causes are low refrigerant levels, a blocked filter, or a failing compressor. This isn’t something to attempt to fix yourself — refrigerant handling requires a qualified engineer, and attempting DIY repairs may void your warranty. Give us a call and we’ll diagnose the issue quickly.
Strange Noises from the Unit Humming, rattling, or grinding sounds are warning signs that something internal may be loose, worn, or failing. The sooner these are investigated, the less likely you are to face a costly breakdown. Our engineers are experienced at diagnosing unusual sounds and getting systems back to full operation.
Water Leaking Around the Unit Water pooling around your air conditioning unit is usually caused by a blocked condensate drain, frozen coils, or an installation issue. Left untreated, this can cause damage to walls, flooring, and nearby electrics. If you spot a leak, switch the unit off and contact a professional promptly.
Bad Odours or Musty Smells Musty or unpleasant smells from an AC unit are often a sign of mould or bacteria growth inside the system, or a clogged filter. Beyond being unpleasant, this can affect air quality and aggravate allergies. A professional clean will resolve the issue and restore fresh, clean airflow.
Unit Won’t Turn On If your system fails to power on at all, the cause could be a tripped circuit breaker, an electrical fault, or a thermostat problem. For safety reasons, always have a licensed technician inspect electrical components rather than attempting to investigate yourself.
Cooling Tips to Get the Most From Your Air Conditioning
Beyond maintenance, a few simple habits can make a big difference to how effectively your system cools your home or workplace:
Keep windows and doors closed while the system is running. Every time warm air enters from outside, your unit has to work harder to compensate. Close doors to unused rooms to concentrate the cooling where you need it most.
Block out direct sunlight. Close curtains or blinds in rooms that get direct sun, particularly during the hottest part of the day. This alone can make a noticeable difference to how hard your system has to work.
Don’t position anything directly in front of or above the unit. Furniture, curtains, or other objects blocking the airflow will reduce efficiency significantly.
Use fans to circulate the cooled air. A ceiling or desk fan used alongside your air conditioning can help distribute cool air more evenly around the room, making the space feel cooler without turning the thermostat down further.
If you’re away for an extended period, raise the temperature setting rather than switching the system off entirely. This keeps the space from heating up excessively while saving energy.
Have a trusted, professional check and inspect your air conditioning every year
An air conditioning unit is a significant investment, and like any other investment, it’s essential to have it checked out by a professional every year. A professional will clean the filters, check the coils, and ensure everything runs correctly. Then, if there are any problems, they can be fixed before they worsen. Not only will this keep your air conditioning unit running smoothly, but it will also help extend its life.
Bonus Money-Saving Tips!
- Set the thermostat to a comfortable temperature and no lower. This will save you money because the compressor won’t have to work harder than necessary.
- Close your blinds and seal cracks in your home during the day when rooms aren’t being used for an extended period. This will also help keep your home cooler and stay cooler longer when needed most.
- Close doors to unused rooms. This will make the air conditioner work less, and your costs go down.
- Close drapes/curtains at night during the summer months. If you have ever slept with your window open, you know that it can become chilly in just a few hours. This will keep your house cooler longer after you turn off the air conditioning unit for the evening.
