London homes in Brentford can be short of outside space, which means a rear wall bracket, a flat roof or a balcony is often the best spot for the outdoor unit. Neighbours’ windows and noise matter as much as appearance when we choose the position, and the pipe run is planned to be short, neat and out of the way.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

What affects the cost of air conditioning
Your quote is based on your property. We consider:
- The size of the job
- What electrical work the job needs
- Whether it’s a one-off job or part of a maintenance contract
Every job is different, so we price each one individually. The system, the access, the pipe routes and the parts involved all make a difference.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Where the outdoor unit is, or where you’d like it
- The paperwork from the last service, if you have it
- Your consumer unit or fuse board
Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. Once we’ve looked at the job, from pictures or on a survey, you get a fixed price. To get going, phone us on 07833 053749 or send an email.
What happens on the day
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we’ve done and answer any questions, and anything that needs attention later is pointed out. All told, the work takes a day or more, depending on the number of rooms, the pipe routes and the access. If a freeholder or agent needs to agree the work in Brentford, we can send them the details.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
How to prepare
- Unlock any gate, garage or side passage we need
- Have the make and model of any existing unit to hand
- Make sure we can reach the consumer unit or fuse board
How to get a quote
Quotes don’t take long. Send a few details and pictures, and we reply the same working day. If we need to see the property first, we book a survey at a time that works for you.

What else we do in Brentford
Air conditioning in Brentford: the local picture
VOA council tax data show about 38% of homes across Brentford and its surrounding area were built in 2000 or later, and the 2021 Census found about 66% of households live in flats. Newer homes normally have cavity walls and loft space that make pipe runs easier, though some estates have planning conditions or covenants worth checking. 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.
Kew Palace (roughly 0.5 miles south-east) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on. Plenty of people near Brentford station split the week between the train and a spare room, and that spare room is often the first to get a unit.
Brentford is about 2 miles south of Ealing, in Greater London. Whether you’re in the middle of Brentford or further out, we cover air conditioning, from a single room to a whole building.

Owner checks or an engineer?
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
Don’t move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
What the work involves, system by system
Multi-split systems
Two rooms on a multi-split are typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. The pipe routes to each room make the biggest difference to the price.
Pipework and condensate drains
Cooling produces water as the air is dried, which the condensate drain takes away. Where it can’t fall naturally to a drain, a condensate pump lifts it, and we plan that on the survey.
Common questions in Brentford
Do I need planning permission for air conditioning in Brentford?
It depends on the property. Central Brentford is a short walk from the St Paul's Brentford Conservation Area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask Hounslow council, which is normally the planning authority for Brentford.
Can you do air conditioning in Brentford?
Yes. Brentford is one of the places we cover. To start, ring us on 07833 053749 or use the quote form with a few pictures.
How long does air conditioning installation take?
It takes about a day for a single-room system, longer for multi-room and ducted systems. The survey tells us how long your installation will need, so you can plan around it.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
How soon will you get back to me?
On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
