What a repair looks like in Chells
About 29 miles out from central London, Chells is part of the South East area we work across. The Valuation Office Agency’s council tax figures date about 56% of homes across Chells and its surrounding area to the post-war years, 1945 to 1972, and the last census (2021) found about 49% of households in terraced houses. With a terrace, access to the rear for the outdoor unit is the main thing to tell us.
For a school like The Nobel School, urgent repairs can be booked right away and bigger work in the holidays. The rating label on the unit gives the model number, which helps us bring the right parts.

About our air conditioning repair in Chells
Age alone doesn’t decide whether a repair is worth it. A system with a failed fan motor may be well worth repairing, while one with a failed compressor might not be. We look at the fault, the parts, the refrigerant and how well the system suits the room, then give you an honest view. If you are dealing with ice on the pipework or the coil and a unit blowing warm air, we can sort it out.
In a place like Chells, outdoor units can be close to hedges and gardens, where leaves and cuttings can clog the coil and cut the cooling. We check the coil early on.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Chells: your questions answered
Do you cover Chells for emergency air conditioning repairs?
Yes: ring the emergency line, day or night, from anywhere in Chells. Say what the system is doing and whether it shows a code, and we will advise on the next step.
Do you cover Chells for air conditioning repair?
We do: Chells falls inside our working area. Tell us a little about the job and we’ll take it from there.
When will I hear back?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Send us the make and model, and any records you have.
How much is an air conditioning call-out?
The first step is a diagnosis, from £75 + VAT, and then you get a fixed price for the repair. Nothing goes ahead without your agreement.
Why is water dripping from my indoor unit?
The condensate drain or pump is the usual cause: a blocked pipe, a kinked hose or a failed pump. Turn the system off to stop the water and give us a call.
Does servicing affect my warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Either way, keep a record of every service.
What happens if it’s left?
For a newer system, a fault may be covered on the manufacturer’s terms. Send us the make, model and installation date and we’ll explain how the manufacturer’s terms are likely to apply first. Getting the date in early helps for a job in a place like Chells.
The price reflects the work, not guesswork. That is why we look at the job first, from photos or on a survey, and the price is agreed before we start.

How the visit works
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us.

- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Prescribe: tell you the cause and the fixed cost of the cure.
- Where a repair doesn’t make sense, you will hear it from us, with the alternatives.
- Then the fix, with leaks repaired before any refrigerant is added.
- Sign off: prove it works and record the visit.
Getting ready for the visit
- Make sure someone can let us in at the agreed time
- Move furniture away from the wall where we will be working
- Plan for pets to be kept clear during the visit

Advice
What the work involves, system by system
VRF systems
On larger VRF systems, the refrigerant charge can be big enough to need regular leak checks under the F-gas rules. Leak repairs are written into the F-Gas records for the operator’s records.
Refrigerant leaks
A low refrigerant charge always means a leak. The leak is found and fixed, then the circuit is tested, evacuated and recharged and every step is recorded.
