Air conditioning in Coulsdon
Thinking about air conditioning but not sure where to start? Just call 07833 053749 or write to us at info@aircondoctor.co.uk with pictures of the rooms and the outside of the property, and we’ll reply the same working day to arrange a survey or a quote. Air con, air conditioning, a split system: whatever you call it, in Coulsdon it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
Top-floor flats and rooms with big south- or west-facing windows tend to be the first to overheat in London. Many people start with one wall-mounted unit in the room that suffers most, while a multi-split serves several rooms from one outdoor unit, which helps where outside space is limited.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual so it’s to hand next time.

Safe owner checks
Don’t 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 electrics need care too. Ask us to quote for a move instead.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and ring 07833 053749 or email us.
Why deal with it now?
The outdoor unit’s position is worth getting right first time. Placing it well keeps noise away from bedrooms and boundaries and makes servicing easier, and it can make a difference to planning. It’s agreed on the survey, not on the day. Planning ahead in Coulsdon means you choose the date, not the weather.
No two properties are the same, so we price each one individually. The system, the access, the pipe routes and the parts involved all play a part.
Why book with us
- MCS certified heat pump installers
- One contact for properties across the South East and London
- We work on all the leading brands
- F-Gas company certification
How it works
Our engineers arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. The work itself takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Pictures of the space and the outside wall help us plan the work in Coulsdon.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
How to prepare
- Make sure we can reach the consumer unit or fuse board
- Let us know if the units are on a roof, a high wall or in a locked area
- Arrange for someone to be there to let us in

What else we do in Coulsdon
Common questions in Coulsdon
Do I need planning permission for air conditioning in Coulsdon?
That depends on the building and where the outdoor unit goes. Around 3 listed entries sit within 0.5 miles of central Coulsdon. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with Croydon council, which is typically the planning authority for Coulsdon.
Can I have air conditioning in a flat in Coulsdon?
Often, yes, but the lease and the freeholder usually have a say. 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.
Do you provide F-Gas records?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for breakdowns that cannot wait. Call 07833 053749 and tell us what’s happened.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re 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.
How much is air conditioning for one room?
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 pictures.
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 tell you why.
Air conditioning in Coulsdon: local notes
The Valuation Office Agency’s council tax figures show about 38% of homes across Coulsdon and its surrounding area date from 1919 to 1939, and about 62% of households live in detached or semi-detached houses, according to the last census (2021). We check the wall construction on homes of that age, as it decides how the pipework goes through. 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 4.9 miles north-west stands Nonsuch Mansion. Listed homes in any area need consent first, so tell us if yours is one. Older streets near St Andrew's Church may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes.
