Air conditioning servicing in Keston
For homes with one or two units and businesses with many, we can set up a maintenance contract. The visits, the scope and the cost are fixed with your quote, so the system is looked after on a regular schedule. Common call-outs are for no service record for the last year or more and weaker cooling than last year, across wall-mounted split systems, air-to-air heat pumps and multi-split systems.
In Keston, a business system may need a leak check by law as well as a service, depending on how much refrigerant it holds. We record the checks and tell you when the next one is due.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Servicing in Keston: local notes
Central Keston is inside the Keston Village Conservation Area. There are 4 conservation areas within a mile of the centre of Keston. Historic England lists about 6 buildings and structures within half a mile of the centre of Keston, including Leafy Grove House (grade II). That only matters for replacements, where a new outdoor unit on a protected building can need consent. Valuation Office Agency council tax records show about 31% of homes in the Keston area date from 1919 to 1939, and about 79% of households live in detached or semi-detached houses, according to Census 2021 figures. Access to the outdoor unit is the one detail that most changes how a visit is planned. City dust and debris build up on London outdoor units, which is why servicing matters.
A service once a year suits most home systems, and some business systems need more. Schools such as Keston Church of England Primary School can book servicing for half term or the summer break, when rooms are empty.

The process
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we have done and answer any questions, and anything that needs attention later is pointed out. The visit takes anything from an hour for a simple split system to most of a day for a larger installation. A few pictures of the room, the outside wall and the fuse board help us plan a job in Keston.
- When you book, we ask what make it is, how many rooms it serves and whether anything seems wrong.
- We run the system first and see how it’s performing.
- We clean the filters and coils and make sure the condensate drains away.
- Electrical connections, controls and refrigerant performance are checked, with an F-gas leak check where the system requires one.
- You get a service record, with anything that needs attention explained.
How to prepare
- Make sure we can reach the consumer unit or fuse board
- Tell us about parking and loading
- Arrange for someone to be there to let us in

Questions from Keston
How do I get a quote for air conditioning servicing in Keston?
Send us pictures of the room or the system and a few details about the property. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
How often do you service systems in Keston?
Once a year suits most home systems. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Is a regas part of an air conditioning service?
A service doesn’t include adding refrigerant. If a system has lost refrigerant, it has leaked from somewhere. We check the refrigerant performance, and if we suspect a leak we explain how it can be found and repaired.
Is an F-gas leak check a legal requirement for my system?
The requirement starts at 5 tCO2e. Plenty of small splits sit under it, as 3 kg of R32 works out at about 2.0 tCO2e. We read the charge from the label and work it out for you.
How long does the work take?
The work itself takes a short visit for one split system, longer for multi-split, ducted or commercial plant. Bigger or more complicated systems take longer, and we will tell you what to expect.
Is Keston in your area?
Yes. Our area takes in London and the counties of the South East, Keston included.
After we have gone
Looking after it is simple, and it helps at the next service:
- Keep doors and windows closed while the system is cooling
- Clear leaves and debris from around the outdoor unit
- Keep to an annual service, or more often if needed
Run the system for a while after the visit and check it feels right. If anything seems off, ring 07833 053749 or use the quote form and we’ll look into it.
Make sure condensate pipes outside are not crushed, blocked or buried. If the outlet is blocked, the water has to go somewhere, and that is usually back towards the indoor unit.
Rented and managed buildings
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party and send the records to whoever needs them.
From a single flat to a whole estate, you get the same standard: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
A customer’s words
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
