How we handle air conditioning repair in Northumberland Heath
Diagnosis call-outs start from £75 + VAT. When the cause is found, the repair is priced before anything else is done, so you can decide with the facts in front of you. Typical jobs include a system that won’t switch on and water leaking from the unit or through the ceiling, on heat pumps, wall-mounted split systems and VRF systems.
In Northumberland Heath, as across London, air conditioning works hard in hot spells, which is when weak cooling, leaks and error codes tend to appear. A photo of the error code and the unit’s label helps us arrive with the right parts in mind.
Each manufacturer sets its own warranty period. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

Northumberland Heath questions
Is there an emergency air con repair line for Northumberland Heath?
The emergency line is open around the clock, and Northumberland Heath is one of the places it covers. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
How do I get a quote for air conditioning repair in Northumberland Heath?
Start with a short message: the address, what you need and a picture or two. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Will skipping a service affect the warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Keep every service record either way.
My system uses R410A. Can it still be repaired?
Yes. Repairing and recharging existing R410A systems is still legal. As the GB phase-down continues, R410A is getting harder and dearer to buy, so for older systems we compare the cost of a repair with a replacement.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before booking, and we’re happy to show ours.
How long does the visit take?
It depends on the job, but as a guide it takes anything from an hour or so to a full day, depending on the fault and the parts. We will confirm it with the quote.
My system uses R22. Can it be repaired?
Replacement is usually the better answer. 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 typically the better investment.
What a repair looks like in Northumberland Heath
3 conservation areas lie within a mile of central Northumberland Heath. Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first. About 40% of homes in and around Northumberland Heath were built between the wars, according to VOA council tax data. If the outdoor unit is high up or behind a locked gate, mention it when you book. London repairs often depend on reaching the outdoor unit, so access details help us plan.
When cooling fails at a school like King Henry School, we can time non-urgent repair work around lessons. Shops and offices around Barnehurst station often can’t wait for cooling to come back, which is what the 24/7 line is for.

How the job changes from property to property
VRF systems
VRF systems often hold enough refrigerant to need regular F-gas leak checks. Any leak we find and repair is recorded for the operator’s records.
Circuit boards and sensors
Circuit boards and temperature sensors control how the system runs. Sensor faults can stop the system or confuse it, and boards can fail after a power surge or with age.
What air conditioning repair can’t fix
Air conditioning repair cannot fix everything, and we will tell you before we start. It doesn’t solve:
- A building problem rather than a system fault
- A discontinued model with no parts available
- A system that was undersized for the room in the first place (that needs a bigger system, not a repair)
Not sure which it is? You can call 07833 053749 or write to us at info@aircondoctor.co.uk and we will tell you honestly before booking.
What the work covers
- Heat pumps
- Ceiling cassettes
- Ducted systems
- Wall-mounted split systems
- Multi-split systems
- VRF systems
What you can do yourself, and what needs us
Do not move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. Ask us to quote for a move instead.
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.

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’ve done and answer any questions, and anything that needs attention later is pointed out. All told, the work takes anything from an hour or so to a full day, depending on the fault and the parts. A note on parking and access helps us plan a visit to Northumberland Heath.
- 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.
- The treatment: the repair itself, with any leak found and fixed before recharging.
- Finally, a check that it’s working and a record of what we did.
Before we arrive
- Arrange for someone to be there to let us in
- Clear access to the fuse board
- Mention any parking restrictions near the property
