Air conditioning for homes and businesses in St Mary Cray
Think of it as diagnose, treat and sign off: the survey diagnoses what the rooms need, the installation is the treatment and commissioning is the sign-off. The sign-off includes testing every mode, showing you the controls and handing over the F-Gas records. Air con, air conditioning, a split system: whatever you call it, in St Mary Cray it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
Across London, and in St Mary Cray 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, and we can give you the details they’ll ask for.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

What we do, step by step
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we have done and answer any questions, and anything that needs attention later is pointed out. All told, the work takes anything from a day for one room to several days for a multi-room or ducted system. Before a visit in St Mary Cray, we ask where the van can stop and how we reach the outdoor unit.
- We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
- We size the system for each room, then send a fixed-price quote with the units and where they go.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.
Getting ready for the visit
- Clear a path to the units and the space around them
- Let us know where we can park and unload
- Mention any managing agent or landlord rules we need to follow

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, the quote is fixed before anything goes ahead.

Do you need air conditioning in St Mary Cray?
Everything that uses electricity in a room ends up as heat. A home office with a couple of screens, or a meeting room with a few people in it, warms up quickly, even when it is not especially hot outside.
Any of these is worth a proper look:
- Rooms heated by plug-in heaters
- A portable unit with a hose out of the window
- Rooms under the roof that stay hot into the night
If you work from home near St Mary Cray station, a home office that overheats is one of the easiest rooms to cool.
Questions to ask before booking
- What the manufacturer’s warranty covers and for how long
- Whether the quote shows VAT clearly
- Whether the price is fixed or an estimate

What else we do in St Mary Cray
Why deal with it now?
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. Sizing each room properly on the survey avoids both. Getting the work done in St Mary Cray before summer avoids the busiest weeks.

Owner checks or an engineer?
Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. Ask us to quote for a move instead.
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.
Air conditioning in St Mary Cray: the local picture
The Valuation Office Agency’s council tax figures date about 42% of homes in and around St Mary Cray to the post-war years, 1945 to 1972. Homes of that age typically have cavity or solid brick walls, and we check which before planning the pipe route. London installs often hinge on outside space, the lease and access to the building.

St Mary Cray questions
Do I need permission to put air conditioning in my flat in St Mary Cray?
Normally, yes, though leaseholders normally need the freeholder’s agreement. 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.
Is air conditioning in St Mary Cray permitted development?
It comes down to the building and the spot chosen for the outdoor unit. The half-mile around the middle of St Mary Cray holds about 15 listed buildings and structures. 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 isn’t allowed under those rules. If there’s any doubt, we ask the local planning authority (for St Mary Cray, normally Bromley council).
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
Do you have a 24/7 line?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we’ll talk you through the next steps.
How quickly will you reply?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
How much does air conditioning installation cost?
Single-room systems start from £1,200 + VAT and are typically up to £2,200 + VAT. That covers supply, installation, commissioning and the F-Gas paperwork and is fixed after a survey or from photos.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us in St Mary Cray and across Greater London. Tell us who should receive the paperwork.
