Air conditioning for homes and businesses in Dormers Wells
Thinking about air conditioning but not sure where to start? Send a few photos of the rooms and the outside walls when you phone 07833 053749 or send an email, and you’ll hear back from us the same working day about a survey or a fixed-price quote. Whether you call it air con, air conditioning or an air-to-air heat pump, it’s the job we do every week across Greater London.
Many installs in Dormers Wells can go ahead as permitted development, but listed buildings, conservation areas and flats need more care: we flag that at the survey.
Across London, and in Dormers Wells too, a lot of air conditioning goes into flats and terraces rather than detached houses. That shapes the job: where the outdoor unit can go, how the pipework reaches it and who needs to agree first. A freeholder or managing agent often has a say in a flat, and we can give you the details they’ll ask for.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

What owners can safely do
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. Ask us to quote for a move instead.
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
What happens on the day
Each visit follows the same order: check the plan with you, protect the area, do the work, check the system and talk you through it. The visit itself takes a day or more, depending on the number of rooms, the pipe routes and the access. A few pictures of the room, the outside wall and the fuse board help us plan a job in Dormers Wells.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
Getting ready for the visit
- Clear the space around the indoor unit, or where it will go
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Clear access to the fuse board
How to get a quote
Quotes do not take long. Send a few details and photos, 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.
Advice
Questions from Dormers Wells
Can you fit air conditioning in a London flat in Dormers Wells?
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.
Can you do air conditioning in Dormers Wells?
Yes. We work across London and the South East from our base in East Grinstead, and Dormers Wells is part of that. Just call 07833 053749 or fill in the contact form with a few details.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Dormers Wells and across Greater London. Let us know who the records should go to.
How does the warranty work?
It’s the manufacturer’s warranty, which varies by brand. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
Where does the outdoor unit go?
Wall brackets, ground level and flat roofs are all options, wherever the pipe route, airflow and servicing access work best. We also think about noise near bedrooms and neighbours and position can affect planning.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.
Do you offer emergency call-outs?
Yes, 24/7. Call the emergency line and tell us the make, the symptoms and any error code, and we will talk you through the next steps.
Air conditioning in Dormers Wells: local notes
About 54% of homes across Dormers Wells and its surrounding area were built between the wars, according to VOA council tax data. Homes of that age usually have cavity or solid brick walls, and we check which before planning the pipe route. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.

When to call us in Dormers Wells
Portable units are often where people start, and why they call us. A portable unit has to vent its warm air through a hose out of a window, which lets some heat back in, and its compressor sits in the room with you. With a split system, the compressor lives outside.
Common reasons people call us are:
- Rooms that get too hot to sleep or work in
- Too many options and no clear advice
- A study or office that overheats during the day
Osterley House, about 1.9 miles south, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.
