How we handle air conditioning repair in Swiss Cottage
Refrigerant does not get used up, so if it’s low, there’s a leak. Simply adding gas means it will leak away again. We find and fix the leak, pressure test, evacuate and recharge to the manufacturer’s charge, then record it in the F-Gas records. Typical jobs include a flashing light and a system that won’t run and air conditioning running but not cooling, on wall-mounted split systems, heat pumps and ducted systems.
London systems in Swiss Cottage often run long hours in summer, and that’s when faults show: weak cooling, water leaks, error codes or a unit that will not start. 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 explain those terms on your quote. Each brand sets its own conditions, and we’re happy to talk you through them.

FAQs for Swiss Cottage
Can I get a fixed-price quote for air conditioning repair in Swiss Cottage?
Send us photos of the room or the system and a few details about the property. Where photos aren’t enough, a survey comes first and the fixed-price quote follows.
Is there an emergency air con repair line for Swiss Cottage?
The emergency line is open around the clock, and Swiss Cottage 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.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and tell you why.
What does F-Gas certified mean?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That isn’t optional: it’s required by law, and AirCon Doctor is certified.
Why is my air conditioning blowing warm air?
Common causes are a blocked filter, the wrong mode or set temperature, an outdoor unit that can’t breathe, a failed sensor or board, or low refrigerant from a leak. Start by checking the filter and the mode, and if that does not fix it, phone us on 07833 053749.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Is the equipment covered by a warranty?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition so it’s worth keeping the service records.
Air conditioning repairs in Swiss Cottage: local notes
The Valuation Office Agency’s council tax figures put about 47% of homes in and around Swiss Cottage before 1919, and the last census (2021) found about 90% of households live in flats. If you live in a flat, mention any roof hatch, balcony or managing agent we will need to get to the outdoor unit. London repairs often depend on reaching the outdoor unit, so access details help us plan. The Belsize Park Conservation Area is within about a third of a mile of the centre of Swiss Cottage. There are 12 conservation areas within a mile of the centre of Swiss Cottage. Listed buildings are part of the picture here: about 123 within half a mile of the centre, such as Belsize Fire Station (grade II*). For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building.
Near South Hampstead station, as anywhere, a photo of the error code on the controller is the quickest way to start a repair. If a system fails at a school such as The UCL Academy, our 24/7 line takes the call, and planned repairs can wait for the holidays.
Swiss Cottage is about 1 mile south of Hampstead, in Greater London. Wherever you are in the NW3 postcode area, we can help with air conditioning repair. Across Greater London, we cover 764 places, and Swiss Cottage is one of them.
The closest recent job we can point to from Swiss Cottage was on East Hill, Wandsworth (SW18), about 6 miles south: installing a Daikin wall-mounted unit in the open-plan living area.
If you need air conditioning repair at a property on Avenue Road, Acacia Road and Harben Road or a nearby road, our engineers can take on the work.

Landmarks near Swiss Cottage
Locally, jobs take us to houses, flats and workplaces close to Cafe Med pub, Holy Trinity CofE Primary School and Primrose Hill, among other places. Nearby too are Cecil Sharp House (1.1 miles east) and St. Mary's Town and Country School (within half a mile north-east). There’s a railway station in Swiss Cottage itself: South Hampstead station. Nearby you will also find Montfichet's Tower (3.7 miles south-east) and Isokon Gallery (0.8 miles north-east). Not far away are The Long Water and Primrose Hill.
What you can do yourself, and what needs us
On air conditioning, the filters in the indoor unit are usually the one part owners can clean where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
Rented and managed buildings
We regularly work with managing agents. Tell us the property, the work and the access arrangements, and we will send a fixed-price quote.
Portfolio owners often want one contractor and one number. We work across London and the South East, so a run of properties can go into one programme and kept on a regular cycle.

What happens if it’s left?
If your system uses R22, the options are narrower. R22 is an ozone-depleting refrigerant and new R22 cannot be used for servicing, so a refrigerant fault on an R22 system normally points to replacement. We explain why and quote for a new system if that’s the right answer. Consents in London blocks can take time, which is another reason to plan the job in Swiss Cottage early.
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you are not sure what’s needed, call us on 07833 053749 or send an email and we will give you an honest view and a fixed price.

How the visit works
Protection comes first: dust sheets over floors and furniture near the work, and we ask before moving anything. Then the electrics are made safe and the work begins. It takes an hour or two to diagnose most faults, with the repair time depending on what we find, and we tidy up before we leave. Let us know who controls access to the building in Swiss Cottage, as that saves time on the day.
- It starts with the symptoms: what the unit is doing, the make and any code on the display.
- The engineer reads the fault codes and checks the electrics, airflow, drain and refrigerant circuit.
- Once the cause is found, we explain it and fix the price for the repair.
- The repair is carried out, and any refrigerant work is leak tested and recorded.
- Before leaving, we run it through its modes and write up what was found and done.
How to prepare
- Keep pets and children away from the work area
- Make sure we can reach the outdoor unit, or where it will go
- Make sure we can reach the consumer unit or fuse board
