About our air conditioning servicing in Merton
For an annual service, the price is £95–£150 + VAT, confirmed before the visit is booked. Multi-split, ducted and commercial systems are priced once we know what’s there. Either way, you know the cost before the engineer arrives. Typical jobs include an unpleasant odour when the system runs and warning lights on the indoor unit, on air-to-air heat pumps, multi-split systems and ceiling cassettes.
We plan the trip to Merton and can service more than one unit in one visit, which keeps it simple.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

Merton questions
Is Merton within the area you cover?
Yes. Merton is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.
Does my air con in Merton need a yearly service?
Usually once a year for homes, more often for busy business systems. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Can I fit air conditioning or a heat pump myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s the law, not just our preference, and it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.
How long will the engineer be here for the service?
Expect it to take an hour or two for most homes, and longer where there are several indoor units or a ducted system. Access and the number of units decide most of the time, and we will give you an idea when we book.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before you book, and we’re happy to show ours.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
Do you look at the job first?
Yes. Every job is looked at first, on a survey, or from your photos and details where the job is simple. A fixed-price quote follows.

What you can do yourself, and what needs us
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo of the display helps even more.
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Keeping systems in Merton running
Valuation Office Agency council tax records show about 44% of homes in Merton and the neighbourhoods around it were built in 2000 or later, and the 2021 Census found about 76% of households in detached or semi-detached houses. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day. Church of St Swithin, listed at grade I, is one of roughly 8 protected buildings and structures in the half-mile around Merton’s centre. If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit.
Spring is a good time for a service, before the system is needed for cooling. Water dripping from the indoor unit often traces back to a drain that needs clearing.

What air conditioning won’t do

- Heat gains the system was never sized for
- A failed compressor, fan motor or circuit board, which needs a repair

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.”
