How we handle air conditioning servicing in Chessington
A manufacturer’s warranty can come with conditions, and regular servicing may be one of them. Each brand sets its own terms and we are happy to go through them with you. Our service record shows the work was done. The work covers ducted systems, ceiling cassettes and VRF systems, and people most often call us about iced-up coils or pipework and a unit showing a fault code.
In a London area like Chessington, many systems run hard in summer and for heating in winter, so a yearly service keeps them efficient. Outdoor units on balconies and roofs pick up city dust and debris, which a service clears.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

Safe owner checks
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Chessington questions
Can you do air conditioning servicing in Chessington?
Yes. We work across London and the South East from our base in East Grinstead, and Chessington is part of that. Tell us a little about the job and we will take it from there.
Does my air con in Chessington need a yearly service?
A yearly visit is right for most households. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
How much time does an air con service need?
A typical service takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Ducted units in ceiling voids and outdoor units in awkward places can add time, and we will tell you in advance.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Do you top up refrigerant during a service?
A service does not include adding refrigerant. If a system has lost refrigerant, it has leaked from somewhere. Where the checks point to a leak, we explain the options for finding and fixing it.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we’ve done.
Which accreditations do you hold?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Keeping systems in Chessington running
Listed buildings are part of the picture here: about 4 within half a mile of the centre, such as Church of St Mary the Virgin (grade II). We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that. About 43% of homes in and around Chessington were built between the wars, according to Valuation Office Agency council tax records. Access to the outdoor unit is the one detail that most changes how a visit is planned. London outdoor units collect city dust and grime, so the outdoor coil gets particular attention on a service.

What air conditioning servicing can’t fix
Before booking, it helps to know what’s not included:
- Heat from large windows, roof spaces or equipment beyond the system’s capacity

- Poor original installation, such as drains without a proper fall
If you’re not sure, just give us a ring on 07833 053749 or send an email and we will give you a straight answer before booking.
Parts of the system we cover
- Ceiling cassettes
- Ducted systems

- Wall-mounted split systems
What we are called out for in Chessington
The outdoor unit lives outside. Leaves, grime and plant growth gather on the fins and around the unit, which makes it harder for the unit to shed or pick up heat.
If any of these sounds familiar, it’s worth a diagnosis:
- A service that is overdue
- Error codes or flashing lights on the indoor unit
- Smells coming from the indoor unit
Site managers at schools like Castle Hill Primary School can have the site’s units serviced during a holiday.

How it works
On the day, we arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. On site, it takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. If a freeholder or agent needs to agree the work in Chessington, we can send them the details.
- We start with the details of the system and anything you’ve noticed.
- The indoor units are opened up and the filters, coils and drain trays cleaned.
- The outdoor unit gets its own clean, with leaves and debris cleared away.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- If a repair is needed, you hear why and what it costs before anything is done.
Preparing for the visit
- Keep pets and children away from the work area
- Let us know if the building has a permit or sign-in process
- Give us access to the outside wall, roof or yard where the outdoor unit sits
