About our air conditioning servicing in Chiswick
For an annual service, the price is £95–£150 + VAT, confirmed before the visit is booked. Larger systems with several indoor units, ducted units or commercial plant are priced on their details. Either way, you know the cost before the engineer arrives. If you are dealing with frost or ice on the refrigerant pipes and F-gas leak checks falling due, we can sort it out.
In Chiswick, the outdoor unit can be on a balcony, a roof or a rear wall, as that affects how long the service takes. If the building has a managing agent, we can book in with them.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

How the visit works
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work takes a short visit for one split system, longer for multi-split, ducted or commercial plant. If your building in Chiswick has a managing agent, a concierge or sign-in rules, mention them when you book.
- You tell us the brand, the number of indoor units 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.
- Readings are taken on the electrics and refrigerant circuit, and the controls are tried in each mode.
- We explain what we found and price any repair before it’s done.
Before we arrive
- Mention any roof access, ladders or high-level work
- Have the make and model of any existing unit to hand
- Clear access to the fuse board

What a service looks like in Chiswick
The centre of Chiswick lies within the Glebe Estate Conservation Area. 13 conservation areas lie within a mile of central Chiswick. Listed buildings are part of the picture here: about 166 within half a mile of the centre, such as Walpole House (grade I). Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first. About 53% of homes in the Chiswick area were built before 1919, according to the Valuation Office Agency’s council tax figures, and about 59% of households live in flats, according to the last census (2021). 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.
For an office near Chiswick station, servicing can be booked before or after working hours.

What we’re called out for in Chiswick
How often a system needs servicing depends partly on how hard it works. A system used for heating as well as cooling, or one in a busy workplace, sees far more running hours and so builds up dirt more quickly.
These are the situations we see most often:
- Humming, rattling or squealing from the system
- Water dripping from the indoor unit
- Air conditioning that is not cooling as well as it did
For a school like The William Hogarth Primary School, maintenance visits can be booked out of term.
What your quote should include
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- If the quote is based on a survey, pictures or a diagnosis
- Whether the manufacturer’s warranty depends on regular servicing
Looking after it afterwards
Every system needs looking after, and most of it is easy. A few tips:
- Rinse the indoor unit filters every few weeks when the system is in heavy use
- Check the condensate pipe outside isn’t blocked or crushed
- Close windows when the air conditioning is running
The best time to book the next service is now, while you remember. Many people book in spring, before the cooling season, or in autumn if they use the system for heating, though any time of year works.
Check that the condensate pipe outside can still drain. A pipe that is been knocked or covered can back up into the indoor unit.
System by system
Wall-mounted, ducted and cassette units
Cassette units are set into the ceiling and blow air in several directions. The grille drops down for the filters, and the drain and pump are checked inside.
Fans and electrics
We test the controls, the modes and the timers to make sure the system responds properly.
Questions from Chiswick
How often do you service systems in Chiswick?
Typically 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.
How do I get a quote for air conditioning servicing in Chiswick?
The easiest way is to call 07833 053749, or email if that’s easier with a few details and pictures. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
What accreditations do you have?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we’re Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Is Chiswick in your area?
Yes. We work in Chiswick and across Greater London, within the London and South East area we cover. For a fixed-price quote, call 07833 053749 or drop us a line.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is recorded and F-Gas records kept where they apply.
Will you regas my air conditioning on a service?
The service checks how the refrigerant circuit is performing, but does not include adding gas. If it’s low, a leak repair comes first and the regas follows with a fixed price for each step.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Send us the make and model, and any records you have.
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.”
