Air conditioning in Coombe Hill
Any installation we do in Coombe Hill follows the same process as everywhere else we work: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. The price is fixed up front and the records are handed over at the end. Air conditioning installation in Coombe Hill starts with a site survey, then a fixed-price quote that names the make and model.
Across London, and in Coombe Hill too, a lot of air conditioning goes into flats and terraces rather than detached houses. So the first questions are where the outdoor unit can sit, how the pipes get to it and whose permission is needed. A freeholder or managing agent often has a say in a flat, so we write up the proposed positions for them to see.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

Coombe Hill: your questions answered
Do you cover Coombe Hill for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Coombe Hill is part of that. Get in touch with the details and we reply the same working day.
Can you fit air conditioning in a London flat in Coombe Hill?
In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and explain why.
How do you keep the place clean during the work?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
How long does it take to fit air conditioning?
It takes a day or more, depending on the number of rooms, the pipe routes and the access. The survey tells us how long your installation will need so there are no surprises.
What does it cost to install air conditioning?
Typically £1,200–£2,200 + VAT for a single-room split, depending on the room, the access and the pipe route. Where you sit in the range depends on pipe length, access, electrics and the model, while commercial systems are priced after a survey.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
Air conditioning in Coombe Hill: the local picture
About 45% of homes in and around Coombe Hill were built between the wars, according to Valuation Office Agency council tax records, and the last census (2021) found about 81% of households in detached or semi-detached houses. Homes of that age typically have cavity or solid brick walls, and we check which before planning the pipe route. A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
About 1.5 miles north-west stands Pembroke Lodge. Listed homes in any area need consent first, so tell us if yours is one. Living close to St John the Baptist? Some older properties in parts like that are protected, and the survey finds out whether yours is.
Coombe Hill is about 2 miles north-east of Kingston upon Thames, in Greater London. We cover Coombe Hill for air conditioning and across the rest of Greater London. Our list for Greater London has 764 entries and Coombe Hill is among them. London, roughly 9 miles off, has its own page on this site.

What the work involves, system by system
Multi-split systems
Indoor units on a multi-split do not all have to look the same, choosing what suits each room, depending on the model. We plan the mix on the survey.
Electrical supply
A dedicated circuit is normally needed. We are NICEIC approved, so we fit and certify the circuit ourselves, which takes care of the Part P notification.
What happens on the day
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 about a day for a single-room system, longer for multi-room and ducted systems, and we tidy up before we leave. Send us a few phone pictures and we can often price a straightforward job in Coombe Hill before visiting.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
Preparing for the visit
- Dig out any previous service or F-Gas records
- Let us know where we can park and unload
- Clear access to the fuse board
How to get a quote
To get a fixed-price quote, ring 07833 053749 with the address and a few details about the rooms or units involved. A few pictures make it quicker. You’ll hear back from us the same working day.

What else we do in Coombe Hill
When something else is needed
It’s worth knowing the limits before booking:
- Building damp that has a structural cause
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- Stuffy rooms that need fresh air rather than cooling
If in doubt, call us on 07833 053749 and we’ll say what we think.
Parts of the system we cover
- Multi-split systems
- VRF systems
- Wall-mounted split systems
- Ducted systems
- Air-to-air heat pumps
- Ceiling cassettes
Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Don’t cover or box in the outdoor unit
- Keep the F-Gas records, commissioning details and warranty information together
- Refit filters properly after cleaning
We clear up before we go: dust sheets lifted, offcuts and packaging cleared, and the holes for the pipework sealed. Outside, the pipework is neatly fixed and protected, so the job looks as tidy as it works.
Do not ignore small changes. Water from the indoor unit, a new rattle or a code on the display normally means something needs attention and catching it early keeps the repair small.
A customer’s words
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
