Air Conditioning Servicing and Maintenance
An annual service keeps running costs down, protects your warranty and keeps the air clean. Domestic systems and commercial maintenance contracts across Surrey.
Why it matters more than people think
Air conditioning does not fail suddenly very often. It degrades. Filters clog, coils fur up with dust, the drain silts, and the system quietly works harder every year to achieve the same result. You do not notice because it happens slowly — you just find the electricity bill creeping up and the room taking longer to cool.
The other half of it is air quality. The indoor unit draws room air across a damp coil. A clean system is fine. A neglected one is a warm, damp surface with a fan behind it, which is not something you want blowing at you while you sleep.
What we check
- Filters cleaned or replaced
- Indoor and outdoor coils cleaned
- Condensate tray and drain cleared and tested
- Refrigerant pressures checked against the manufacturer's figures
- Any sign of a refrigerant leak investigated rather than noted
- Fan motors and bearings checked for wear
- Electrical connections checked and tightened
- Controls and sensors tested through a full cycle
- Running temperatures recorded, so next year has something to compare against
You get the actual readings, not a sticker with a date on it. That record is what turns next year's service into a comparison rather than a guess.
Your warranty almost certainly requires it
Nearly every manufacturer warranty on air conditioning requires documented annual servicing. Skip it and cover can be void, which turns a compressor failure in year four from a warranty claim into a bill. It is the single most common reason people lose cover they believed they had.
Commercial maintenance
For offices, shops, salons and restaurants we can put a maintenance schedule in place and work around your opening hours. For businesses the argument is simpler still: an air conditioning failure in August in a shop or a salon costs you trade for every hour it is down.

Emergency water leak in kitchen
★★★★★
We had an emergency water leak. CGR was able to attend very quickly and help to isolate and stop the leak. It was near the stopcock and underneath some kitchen drawers so it required some cutting of wood to access and took a few hours, but he worked hard to fix it and then cleaned up thoroughly afterwards.
Boiler and radiator fault repair

I had a boiler fault that was actually caused by an airlock in my central heating. Chaudray identified the potential issue quickly and clearly communicated the steps required to fix it. He carried out the work then and there, and the problem was solved. He was very courteous and tidy, too.

Questions
How often does air conditioning need servicing?
Once a year for a domestic system. Commercial systems, and anything running long hours, are usually better on a six-monthly schedule.
Can you service a system you did not install?
Yes, and it is a good idea if you have inherited one with a property and have no service history for it.
Can you service my boiler at the same time?
Yes, and most people do. One visit rather than two, and it keeps both service records in one place.
What if the service finds a problem?
We tell you what it is, what it costs and how urgent it is. Nothing gets fixed without you agreeing first.
