About our air conditioning repair in Gillette Corner
A sealed system shouldn’t lose refrigerant, so a low charge means a leak somewhere. Topping up without a repair only delays the next breakdown. We find and fix the leak, pressure test, evacuate and recharge to the manufacturer’s charge and write it up in the F-Gas records. If you are dealing with ice forming on the indoor unit or pipes and an error code or flashing light on the unit, we can sort it out.
London systems in Gillette Corner often run long hours in summer, and that’s when faults show: weak cooling, water leaks, error codes or a unit that won’t start. The error code on the display, the make and the model are the most useful things to send us.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

Keeping the system healthy
Once we have finished, these simple steps help:
- Leave space around the outdoor unit
- Only let an F-Gas qualified engineer work on the refrigerant
- Have the system serviced once a year
Once the fault is fixed, we test the system in operation. We check it’s cooling or heating as it should and that the fault hasn’t left anything else behind and point out anything else we spotted.
Keep the outdoor unit clear. Anything blocking the outdoor unit makes the whole system strain and debris drawn into the fan can cause noise and damage.
Air conditioning repair in Gillette Corner: the local picture
The Osterley Park Conservation Area lies close to the centre of Gillette Corner, within about a third of a mile. 5 conservation areas lie within a mile of central Gillette Corner. Listed buildings are part of the picture here: about 21 within half a mile of the centre, such as Brentford and Isleworth Quaker Meeting House (grade II*). Swapping an outdoor unit on a listed building or in a conservation area may need consent, so we will flag it if a replacement is needed. Valuation Office Agency council tax records show about 51% of homes in and around Gillette Corner date from 1919 to 1939. Let us know where the outdoor unit sits and whether a ladder is needed to reach it. London repairs often depend on reaching the outdoor unit, so access details help us plan.

Your questions about air conditioning repair in Gillette Corner
Do you cover Gillette Corner for air conditioning repair?
Yes, Gillette Corner is within the area we cover. Get in touch with the details and we reply the same working day.

Can you repair an R22 air conditioning system?
In most cases, we recommend replacement. New R22 cannot be used to service systems, and parts for older units are getting harder to find, so a new system on a modern refrigerant is usually the better investment.
Can you still repair R410A air conditioning?
Yes. We find and fix the leak, then recharge with R410A and record it in the F-Gas records and we’ll give you an honest view on whether it’s worth it.
Which brands do you work with?

What warranty do I get?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
What does F-Gas certified mean?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.

How it works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. So on the day, you don’t need a separate electrician for the electrical side. On site, it takes anything from an hour or so to a full day, depending on the fault and the parts. Some blocks in Gillette Corner need contractor details in advance, so tell us what your building needs.
- It starts with the symptoms: what the unit is doing, the make and any code on the display.
- We diagnose on site, checking the codes, electrics, airflow, drain and refrigerant pressures.
- Once the cause is found, we explain it and fix the price for the repair.
- The repair is carried out, and any refrigerant work is leak tested and recorded.
- Before leaving, we run it through its modes and write up what was found and done.
Getting ready for the visit
- Keep pets and children away from the work area
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Find the manual or the paperwork for the system, if you have it

Advice
How the job changes from property to property
VRF systems
In a VRF system, many indoor units share outdoor plant. Faults are diagnosed through the system’s own fault codes and controls, then confirmed by testing, and repairs are priced before they go ahead.
Ducted and cassette systems
With ducted and cassette units, most of the system is hidden in the ceiling, so access matters. Condensate pumps are common on both, and a failed pump is a frequent cause of water leaks.
A customer’s words
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
