Air conditioning servicing for homes and businesses in Heston
Many manufacturers attach conditions to their warranties, and some of those may include regular servicing. The terms differ from brand to brand, so it’s worth reading yours and we are happy to go through them with you. Our service record shows the work was done. The work covers VRF systems, multi-split systems and wall-mounted split systems, and the jobs we see most are error codes or flashing lights on the indoor unit and new noises from the indoor or outdoor unit.
In Heston, 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.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Why it’s worth doing now in Heston
Smells from an indoor unit tend to come back each time it runs. The cure is cleaning where the dirt has built up instead of covering it up. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Heston early.
The cost depends on the system and the number of rooms or units, how easy the units are to reach and what the work involves. You get a fixed price before we start, so you know where you stand.

What happens on the day
You do not need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we’ve done. A few pictures of the room, the outside wall and the fuse board help us plan a job in Heston.
- A date is fixed and the service price confirmed in advance.
- The engineer runs the system and checks how it’s performing.
- We clean the filters, coils and fans and clear the condensate drain.
- The electrics, controls and refrigerant performance are checked, with a leak check where required.
- A final test run follows, then you get the service record.
How to prepare
- Have the make and model of any existing unit to hand
- Let us know where we can park and unload
- Tell us about any building rules, permits or sign-in
Getting a quote
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
Advice
Signs you need air conditioning servicing in Heston
A slow leak can go unnoticed for a long time. The system just cools or heats a little less well each year, until it cannot keep up on the hottest or coldest days.
Common reasons people call us are:
- Weaker cooling than last year
- Warning lights on the indoor unit
- Drips or damp patches below an indoor unit
Schools such as Westbrook Primary School can book servicing for half term or the summer break, when rooms are empty.

Common questions in Heston
What’s the best way to get a price for air conditioning servicing in Heston?
Use the quote form, or email, with a description of the job. We reply the same working day, and the quote is fixed before any work starts.
How often should air conditioning in Heston be serviced?
Once a year suits most home systems. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.

Do you top up refrigerant during a service?
The service checks how the refrigerant circuit is performing, but does not include adding gas. If gas has been lost, the right step is a leak search and repair, then a regas with a fixed price for each step.

What a service looks like in Heston
The Heston Village Conservation Area is within about a third of a mile of the centre of Heston. Draw a one-mile circle round the middle of Heston and it takes in 5 conservation areas. Listed buildings are part of the picture here: about 5 within half a mile of the centre, such as Church of St Leonard (grade II*). Swapping an outdoor unit on a listed building or in a conservation area may need consent, so we will flag it if a replacement is needed. About 44% of homes in Heston and the neighbourhoods around it were built between the wars, according to the Valuation Office Agency’s council tax figures. Tell us where your outdoor unit is and how to reach it, so we can plan the visit. In London, a yearly clean of the outdoor coil makes a real difference to how well a system cools.
Booking before the first hot spell means the system is ready when you need it.
