Air conditioning servicing in Merton, Greater London

Common problems we fix in Merton
Small refrigerant leaks do not announce themselves. The system just cools or heats a little less well each year and only becomes obvious when the weather is at its extreme.
What we’re most often called about:
- Systems that haven’t been serviced for a while
- Iced-up coils or pipework
- An unpleasant odour when the system runs
For an office near Haydons Road station, servicing can be booked before or after working hours.
What your quote should include
- Whether a new circuit is included and who certifies it
- Whether the company is F-Gas certified, and whether you can check it
- Whether the manufacturer’s warranty depends on regular servicing
How we handle air conditioning servicing in Merton
Whether a leak check is required depends on how much refrigerant the system holds and which refrigerant it is. Under the GOV.UK rules, 5 to under 50 tCO2e means a leak check at least every 12 months, and 50 to under 500 tCO2e means every 6 months. We work out where your system sits and check it accordingly. If the problem is new noises from the indoor or outdoor unit and no service record for the last year or more, we can sort it out.
In Merton, a business system may need a leak check by law as well as a service, depending on its refrigerant charge. The check is recorded, with the next date noted.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

What else we do in Merton
The process
Protection comes first: sheets over the floor and any furniture nearby and nothing is moved without asking you. After that, anything electrical is made safe and we start. It takes an hour or two for most homes, and longer where there are several indoor units or a ducted system, and we clear up before we go. Let us know who controls access to the building in Merton, as that saves time on the day.
- It begins with a few questions about the make, the rooms served and any symptoms.
- Each indoor unit has its covers lifted so the filters, coil and tray can be cleaned.
- The outdoor unit is cleaned and checked, and debris cleared from around it.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- We explain what we found and price any repair before it’s done.
How to prepare
- Let us know where the consumer unit is
- Keep pets and children away from the work area
- Mention any managing agent or landlord rules we need to follow
How to get a quote

Common questions in Merton
How often do you service systems in Merton?
For most homes, once a year. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Can I get a fixed-price quote for air conditioning servicing in Merton?
Send us photos of the room or the system and a few details about the property. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Will servicing keep my manufacturer’s warranty valid?
Warranty terms are set by the manufacturer, not by us. Read the conditions for your brand, as they may include servicing, and keep each service record with the warranty paperwork.
Does my air conditioning need an F-gas leak check?
Under GOV.UK guidance, systems of 5 to under 50 tCO2e need a check at least every 12 months, and 50 to under 500 tCO2e every 6 months. With leak detection fitted, the interval can be doubled, and we can tell you where your system sits.
What does an air con service involve?
We clean the filters and coils, clear the condensate drain and check the fans. The electrics, controls and refrigerant circuit are tested too, with an F-gas leak check where the system requires one.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it, and the quote is based on that.
Aftercare tips
Once we have finished, these simple steps help:
- Check the condensate pipe outside is not blocked or crushed
- Rinse the indoor unit filters every few weeks when the system is in heavy use
- Read the warranty conditions for your brand
After the service, you get a record of what was done, listing the work, the checks and any recommendations. File it with the system’s manual and warranty documents so the service history is in one place.
Check that the condensate pipe outside can still drain. A pipe that’s been knocked or covered can back up into the indoor unit.
Why act early in Merton
Drainage problems tend to grow. What starts as a damp patch under the indoor unit can become water running down the wall, so it’s worth clearing before that happens. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Merton early.
Whatever the property, the quote works the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we’ll explain each part.

Air conditioning servicing in Merton: the local picture
About 42% of homes in Merton and the neighbourhoods around it were built before 1919, according to VOA council tax data, and the last census (2021) found about 49% of households live in flats. In flats, outdoor units are often on balconies, roofs or high walls, so tell us how we reach yours. In London, a yearly clean of the outdoor coil makes a real difference to how well a system cools. The Wandle Valley Conservation Area lies close to the centre of Merton, within about a third of a mile. There are 7 conservation areas within a mile of the centre of Merton. About 15 listed entries lie within half a mile of central Merton, Wheel House at Misters Liberty's Printworks (grade II) among them. We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that.
For a school like Merton Abbey Primary School, maintenance visits can be booked out of term.
