Service checklist
What’s included in an air conditioning service?
Every service visit follows a full checklist, and you receive a written report of what we found and did.
Filters cleaned
Washable filters cleaned and replaced; disposable media changed where fitted.
Coils and fan cleaned
Indoor coil and fan barrel treated to remove dust, bacteria and odours.
Outdoor unit checked
Condenser coil cleared of leaves and debris; fan and fixings inspected.
Refrigerant and leak check
Operating pressures and temperatures checked; joints inspected for leaks.
Electrical inspection
Terminals, isolator and cabling checked for wear, heat damage and tightness.
Drain and performance test
Condensate drain flushed, then cooling and heating output measured and logged.
Frequency
How often should air conditioning be serviced?
| Type of system or use | Recommended servicing |
|---|---|
| Home system used mainly in summer | Once a year, ideally in spring |
| Home system used for heating and cooling | Once a year, plus regular filter cleaning |
| Office or shop | Twice a year |
| Restaurant, salon, gym or dusty workshop | Every three to four months |
| Server and comms rooms | Quarterly, with back-up checks |
F-gas leak check requirements
Separately from routine servicing, UK F-gas rules require leak checks on systems by refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tonnes, every six months from 50 tonnes and every three months from 500 tonnes (with longer intervals allowed where automatic leak detection is fitted). Many single-room domestic units fall below the threshold, but commercial and multi-split systems often don’t. We keep the records for you.
Warning signs
Signs your air conditioning needs a service
Don’t wait for a breakdown on the hottest day of the year. Book a service if you notice:
- The room takes longer to cool, or never quite reaches the set temperature
- A musty or damp smell when the unit starts
- Water dripping from the indoor unit
- Louder fan or rattling noises than usual
- Ice on the pipework or outdoor unit
- Electricity bills creeping up for the same use
If the system has stopped working altogether, our repair team can help.

Servicing questions
Common questions about air conditioning maintenance
Can I clean the filters myself?
Yes, and you should. Most indoor units have washable filters that lift out from behind the front panel. Rinse them in lukewarm water every few weeks during heavy use and let them dry fully. Leave coils, refrigerant and electrics to an engineer.
Do you service systems installed by other companies?
We do. We service most brands of split, multi-split, cassette, ducted and floor-mounted systems across Surrey.
Does skipping a service affect my warranty?
It can. Many manufacturers make their extended warranties conditional on annual servicing by a qualified engineer, so keep your service records.
Is servicing an older system worth it?
Usually, yes — a clean, correctly charged older unit often runs noticeably better. If it uses R22 refrigerant or has repeated faults, we’ll advise honestly on replacement.
