Air conditioning repair for homes and businesses in Dollis Hill
A symptom is only a clue: warm air, drips and error codes can each have several causes. A unit blowing warm air might have a blocked filter, a failed sensor, a fault on the circuit board or a refrigerant leak, so we diagnose before we repair. If you’re dealing with a system that keeps cutting out and poor airflow even with clean filters, we can help.
London systems in Dollis Hill often run long hours in summer, which is when weak cooling, leaks and error codes tend to appear. The error code on the display, the make and the model are the most useful things to send us.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

FAQs for Dollis Hill
Do you cover Dollis Hill for air conditioning repair?
Yes. We work across London and the South East from our base in East Grinstead, and Dollis Hill is part of that. Tell us a little about the job and we’ll take it from there.
Who do I call if my air conditioning fails in Dollis Hill out of hours?
Yes. Our 24/7 emergency line covers Dollis Hill. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Can you still repair R410A air conditioning?
Yes, repairs and recharges on existing R410A systems remain 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.
What does F-Gas certified mean?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
Which accreditations do you hold?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Do you provide F-Gas records?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
How do you keep the place clean during the work?
We start with protection: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.

Honest limits
We’ll always give you a straight diagnosis, so here’s what air conditioning repair will not do:
- A discontinued model with no parts available
- A power cut or a fault on the incoming supply to the building (that’s for the network operator)
- A system that was undersized for the room in the first place (that needs a bigger system, not a repair)
If in doubt, give us a ring on 07833 053749 or fill in the contact form and we will say what we think before you book.

Air conditioning repairs in Dollis Hill: local notes
About 47% of homes in Dollis Hill and the neighbourhoods around it were built between the wars, according to Valuation Office Agency council tax records, and about 48% of households live in flats, according to the 2021 Census. Balcony, roof or high wall? Knowing where a flat’s outdoor unit is helps us bring the right access kit. London repairs often depend on reaching the outdoor unit, so access details help us plan. Dollis Hill’s centre falls inside a designated conservation area. Draw a one-mile circle round the middle of Dollis Hill and it takes in 2 conservation areas. Church of St Michael, listed at grade II, is one of roughly 3 protected buildings and structures in the half-mile around Dollis Hill’s centre. Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first.
Schools such as Our Lady of Grace Catholic Junior School can report a fault on the 24/7 line and have non-urgent work done out of term.

What’s near Dollis Hill

The process
Think of the visit in three stages: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally we test, record and explain. The middle part takes longest, and that takes a single visit for many faults, while some repairs need a second visit once parts arrive. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Dollis Hill.
- Diagnose: test the system until the cause is clear.
- Next, a plain explanation and a fixed price.
- If the repair isn’t worth doing, we say so and explain the options.
- Then the fix, with leaks repaired before any refrigerant is added.
- Sign off: prove it works and record the visit.
Preparing for the visit
- Let us know where we can park and unload
- Have the make and model of any existing unit to hand
- Make sure we can reach the outdoor unit, or where it will go
Getting a price
Every quote shows the VAT clearly, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. To get one, ring us on 07833 053749 or fill in the contact form.
Advice
Common problems we fix in Dollis Hill
Water dripping from an indoor unit is normally about the condensate. The drain may be blocked or kinked, the condensate pump may have failed, or the unit may not be level, and ice on the coil that melts can drip too.
These are the situations we see most often:
- An error code or flashing light on the unit
- Drips from the indoor unit
- A system that will not switch on
If your system near Brent Cross West station stops in a hot spell, our 24/7 line is open.
Questions to ask before you book
- Whether you get F-Gas records where refrigerant is involved
- What’s in the price and what is not
- Whether they looked at the job before pricing it
What the work involves, system by system
Ducted and cassette systems
With ducted and cassette units, most of the system is hidden in the ceiling and access is part of the job. Condensate pumps are common on both, and a failed pump is a frequent cause of water leaks.
VRF systems
VRF systems link many indoor units to shared outdoor units, often across a whole building. We use the system’s fault history and codes, then test to confirm, and repairs are priced before they go ahead.
A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
