How we handle air conditioning repair in Heathrow
Think of it as a doctor’s appointment for your air conditioning: find the cause, put it right and check it’s healthy before we leave. Guessing is expensive, and replacing a board when the fault is a sensor leaves the problem in place. The work covers wall-mounted split systems, ducted systems and ceiling cassettes, and common reasons people get in touch are a system that needs topping up again and ice on the pipework or the coil.
In a village like Heathrow, most air conditioning we repair is in homes, garden rooms and the occasional pub or village business. Describe the fault and send a photo of the unit’s label so we can plan the visit.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

When air con fails in Heathrow
At about 16 miles from central London, Heathrow sits inside the area we cover across London and the South East.
For a home or office near Heathrow Terminals 2 & 3 Rail station, tell us the make, model and error code when you call, so we can plan the repair. Schools such as Bedfont Primary School can report a fault on the 24/7 line and have non-urgent work done out of term.
Heathrow is about 2 miles north-west of Feltham, in Surrey. Heathrow gets the same approach as every job we take on: diagnosis first, a fixed price and proper paperwork when we have finished. Heathrow is one of 395 towns, villages and districts in Surrey where we work. London is in our area too, around 16 miles away.
Our nearest recent job to Heathrow was on Church Street, Staines-upon-Thames (TW18), about 3 miles south-west: installing two LG wall-mounted units in the main office area and a single unit in the client meeting room.
If your postcode is in TW6, you’re inside the area we cover. Close to Heathrow, our area also takes in West Bedfont (1 mile south-west), Hatton (1 mile east), Bedfont (1 mile south-east), Stanwell (1 mile south-west) and Harlington (1 mile north-east).

What else we do in Heathrow
Rented and managed buildings
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.
When the building owner and the occupier are different, the lease or tenancy agreement normally sets out who maintains what. We are happy to deal with either side and send the records to whoever needs them.
Why act early in Heathrow
Waiting for hot weather to see whether a fault sorts itself out rarely works. If the system is faulty now, it will be faulty in a heatwave, when you need it most, so it’s worth having it diagnosed while you can plan the repair. For a village like Heathrow, booking ahead lets us plan the trip properly.
A single unit or a whole estate, the quote is built the same way: the work involved, the access and the equipment. You will have a fixed price before we start, and the quote sets out the VAT.

How the job changes from property to property
Refrigerant leaks
Adding refrigerant without a repair isn’t a fix and the gas simply leaks out again. That’s why we repair the leak first.
Condensate drains and pumps
Most water leaks from indoor units come back to the condensate system. Drains block with dirt and growth, pipes get kinked and pumps fail, and a unit that is not level can spill water too.
How it works
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. On site, the work takes an hour or two to diagnose most faults, with the repair time depending on what we find. Rural lanes and tight entrances are worth mentioning before a visit to Heathrow.
- Diagnose: test the system until the cause is clear.
- Then the prescription: what’s wrong and what it will cost to put right.
- Where a repair doesn’t make sense, you’ll hear it from us, with the alternatives.
- Then the fix, with leaks repaired before any refrigerant is added.
- Finally, a check that it’s working and a record of what we did.
Preparing for the visit
- Tell us about any building rules, permits or sign-in
- Plan for pets to be kept clear during the visit
- Clear the space around the indoor unit, or where it will go

FAQs for Heathrow
Who do I call if my air conditioning fails in Heathrow out of hours?
Yes: ring the emergency line, day or night, from anywhere in Heathrow. Say what the system is doing and whether it shows a code, and we will advise on the next step.
Can you do air conditioning repair in Heathrow?
Yes. We work across London and the South East from our base in East Grinstead, and Heathrow is part of that. Tell us a little about the job and we will take it from there.
What causes ice on the indoor coil?
When airflow drops or refrigerant is lost, the coil gets cold enough to ice. A dirty filter is worth checking first and if that isn’t it, we will find the cause.
Is there a survey before the work?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
How much is an air conditioning call-out?
A diagnosis call-out is from £75 + VAT. When we have found the fault, the repair is priced before we do it. The cost depends on the fault, the parts and access to the units.
Can you repair an R22 air conditioning system?
Replacement is typically the better answer. R22 can’t be topped up with new gas, and parts for old models are scarce, so we’ll quote for a modern replacement and explain why.
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.”
