- Error codes or flashing lights on the indoor unit
Air conditioning servicing in Gillette Corner, done properly
A service is not the same as a regas. The refrigerant circuit is sealed, so a system that’s short of gas has a leak somewhere. If the performance checks point to a leak, we explain the options for finding and fixing it rather than just topping up. If the problem is a unit showing a fault code and leak check records that need bringing up to date, we can sort it out.
Commercial systems in a London area like Gillette Corner may need F-gas leak checks as well as a service, depending on its refrigerant charge. We record the checks and tell you when the next one is due.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

How we price air conditioning servicing
The survey or diagnosis tells us what the work involves. The main factors are:
- What electrical work the job needs
- The brand, model and parts involved
- Access, including height, roofs and ladders
Several rooms, units or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.
Asking for a quote
When you contact us, these details help:
- Where the outdoor unit is, or where you’d like it
- Any error code or flashing light on the display
- The postcode and whether it’s a home, flat or business

Keeping systems in Gillette Corner running
About 51% of homes in and around Gillette Corner were built between the wars, according to the Valuation Office Agency’s council tax figures. If the outdoor unit is high up or behind a locked gate, mention it when you book. City dust and debris build up on London outdoor units, which is why servicing matters. Roughly a third of a mile or less from central Gillette Corner, you reach the Osterley Park Conservation Area. Draw a one-mile circle round the middle of Gillette Corner and it takes in 5 conservation areas. About 21 listed entries lie within half a mile of central Gillette Corner, Brentford and Isleworth Quaker Meeting House (grade II*) among them. If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit.
Schools such as Marlborough Primary School can book servicing for half term or the summer break, when rooms are empty. Businesses close to Syon Lane station can book an early or late slot so the service does not get in the way of trade.

How it works
If the system has to be off for part of the visit, we tell you before any work starts, so you can plan around it. For businesses, we can typically work room by room or zone by zone. On site, it takes an hour or so for a single wall-mounted unit, longer for a multi-split system. The more we can see beforehand, the smoother the visit to Gillette Corner will be.
- First, we agree a time and confirm the cost of the service.
- We switch the system on and check it in operation.
- Then the cleaning: filters, coils, fan and the drain line.
- The electrics, controls and refrigerant performance are checked, with a leak check where required.
- A final test run follows, then you get the service record.
Before we arrive
- Let us know if the units are on a roof, a high wall or in a locked area
- Make sure we can reach the outdoor unit, or where it will go
- Let us know if the building has a permit or sign-in process

System by system
Fans and electrics
Both units rely on fans to move air. The engineer listens for noise and checks for wobble or wear and clean the indoor fan where dust has built up.
Condensate drains and pumps
Some indoor units rely on a small pump to move the water. We check the pump runs and switches as it should since a stuck pump often means water from the unit.

What air conditioning will not do
We’d rather tell you now than sell you work that won’t help, so these are the things it won’t cover:
- A system that is too small for the room it serves
- A refrigerant leak, which needs finding and repairing, not topping up
- Poor original installation, such as drains without a proper fall
If you are not sure, just phone us on 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll give you a straight answer.

Your questions about air conditioning servicing in Gillette Corner
How often do you service systems in Gillette Corner?
Typically once a year for homes, more often for busy business systems. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Can you do air conditioning servicing in Gillette Corner?
Yes. We work across London and the South East from our base in East Grinstead, and Gillette Corner is part of that. To start, call 07833 053749, or email if that’s easier with a few pictures.
Is a regas part of an air conditioning service?
Not as a routine part of the service. The refrigerant circuit is sealed, so a system that’s short of gas has a leak. Where the checks point to a leak, we explain the options for finding and fixing it.
What do you check on an air conditioning service?
Both the indoor and outdoor units are checked and cleaned: filters, coils, drains and fans, then the electrics, the controls and how the refrigerant circuit is performing. A service record follows.
Do you offer air conditioning maintenance contracts?
Yes, and the schedule is set around your system. The price is fixed with your quote, and each visit is recorded.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for problems that can’t wait for a planned visit. Call 07833 053749 and tell us what’s happened.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Tell us the make and model and send any paperwork you have.
