Air conditioning repair in West Hampstead, done properly
When air conditioning stops cooling, leaks water or shows an error code, the symptom rarely tells you the cause. 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. Common call-outs are for ice forming on the indoor unit or pipes and a suspected refrigerant leak, on wall-mounted split systems, VRF systems and ducted systems.
In a managed building in West Hampstead, the repair may need booking through the agent or building manager, so let us know who needs to know we’re coming. Roof access can need keys or permits, which is worth sorting before the visit.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

Before you call an engineer
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. Ask us to quote for a move instead.

What we do, step by step
Our engineers arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes an hour or two to diagnose most faults, with the repair time depending on what we find. Parking bays, permits and roof or balcony access are the first things we ask about in West Hampstead.
- First, a few questions by phone or email about the brand, the fault and anything shown on the controller.
- The engineer reads the fault codes and checks the electrics, airflow, drain and refrigerant circuit.
- We explain the cause and give you a fixed price for the repair before any work goes ahead.
- The fix goes in, with any refrigerant work tested and written into the F-Gas records.
- We run the system, check it’s working properly and note anything else that needs attention.
Getting ready for the visit
- Keep pets and children away from the work area
- Clear access to the fuse board
- Let us know if the units are on a roof, a high wall or in a locked area

West Hampstead: your questions answered
Can you do air conditioning repair in West Hampstead?
Yes. West Hampstead is one of the places we cover. Get in touch with the details and we reply the same working day.
Do you cover West Hampstead for emergency air conditioning repairs?
Yes. Our 24/7 emergency line covers West Hampstead. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Do you look at the job first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Will I get records for the system?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.

If you live in a flat, mention any roof hatch, balcony or managing agent we will need to get to the outdoor unit. In London buildings, outdoor units can be on roofs or in light wells, so let us know where yours is. Central West Hampstead is inside the Redington Frognall Conservation Area. 7 conservation areas lie within a mile of central West Hampstead.

Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first.

Common problems we fix in West Hampstead
Ice on the pipework or the indoor coil is a symptom, not the fault. Low airflow from blocked filters or a failing fan, or low refrigerant from a leak, are the common causes. Switch the system off and let it thaw before calling us.
The things we are asked about most are:
- Air conditioning running but not cooling
- A unit that has lost refrigerant
- Water dripping from the indoor unit
If your system near Finchley Road & Frognal station stops in a hot spell, our 24/7 line is open.
What your quote should include
- Whether they hold F-Gas company certification, not just individual qualifications
- If the quote is based on a survey, pictures or a diagnosis
- What records you get at the end
When it’s something else
Before booking, it helps to know what’s not included:
- No power to the building at all
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is usually the answer)
- A building problem rather than a system fault
