Air conditioning installation in Colliers Wood
Single-room systems are typically £1,200–£2,200 + VAT, while a two-room multi-split is typically £2,800–£4,500 + VAT and three to five rooms £4,500–£8,500 + VAT. Those ranges include supply, installation, commissioning and F-Gas documentation, with commercial and VRF systems priced after a survey. A lot of the calls we get from Colliers Wood are about one room that is too hot to sleep or work in. A single-room split system is often the answer, from £1,200 + VAT.
Space outside is often tight in Colliers Wood, as in much of London, so the outdoor unit may end up on a rear wall, a flat roof or a balcony. We look at noise towards neighbours and windows as well as looks, and we plan the pipe route so it’s as short and tidy as the building allows.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

What happens if it’s left?
Size matters more than brand. An undersized unit runs hard and still can’t keep the room cool; an oversized one cycles on and off and wastes energy. Getting the sizing right at the survey stage avoids both problems. In London, hot spells can bring a rush of calls, so planning the work in Colliers Wood before summer avoids the wait.
The cost depends on the type of system and how many units are involved, how easy the units are to reach and what the work involves. You get a fixed price before work begins, so you know where you stand.

When to call us in Colliers Wood
Rooms overheat mostly because of heat they gain during the day. Sun through large windows, roof lights and glazed doors is the biggest source in many rooms, and once the room has warmed up, it holds on to it into the evening.
These are the situations we see most often:
- A portable unit with a hose out of the window
- Commercial rooms that are too warm for staff
- Rooms under the roof that stay hot into the night
Homes near St Nicholas are a good example of where we look up the heritage status of the building before fixing anything to it.
What your quote should include
- Whether the company is F-Gas certified, and whether you can check it
- Whether the manufacturer’s warranty depends on regular servicing
- Whether they looked at the job before pricing it
How it works
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. On site, the work takes a day or more, depending on the number of rooms, the pipe routes and the access. Send us a few phone photos and we can often price a straightforward job in Colliers Wood before visiting.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Preparing for the visit
- Clear the space around the indoor unit, or where it will go
- Let us know where we can park and unload
- Arrange for someone to be there to let us in

Air conditioning around Colliers Wood
About 55% of homes in and around Colliers Wood were built before 1919, according to the Valuation Office Agency’s council tax figures, and about 56% of households live in flats, according to Census 2021 figures. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. In flats, the lease and the freeholder normally decide where an outdoor unit can go, and the permitted development rules for flats are tighter. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
If you work from home near Tooting station, a home office that overheats is one of the easiest rooms to cool.

Before you call an engineer
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and phone 07833 053749 or write to us at info@aircondoctor.co.uk.
FAQs for Colliers Wood
Can you fit air conditioning in a London flat in Colliers Wood?
In many cases, yes, once the lease and the building’s rules are checked. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Can you do air conditioning in Colliers Wood?
We do: Colliers Wood falls inside our working area. Tell us a little about the job and we’ll take it from there.
Do you look at the job first?
Yes. Every job is looked at first, either on a site survey or from photos and details for simple jobs. A fixed-price quote follows.
Do you have a 24/7 line?
Yes. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we will agree what happens next.
Which manufacturers do you install and repair?
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 tell you why.
Where does the outdoor unit go?
We agree it with you on the survey. It needs space around it to breathe and room for an engineer to service it, and walls or roofs facing a road can raise planning questions. We explain the options and any permissions to check.
Who has to arrange F-Gas leak checks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We will work out which band applies to yours.
