About our air source heat pumps in Thornton Heath
We install air source heat pumps in Thornton Heath and across Greater London, and we’re MCS certified. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We help you work out which suits your home. The work covers underfloor heating, air-to-air heat pumps and air-to-water heat pumps, and the jobs we see most are no space for a hot water cylinder and finding a place for the outdoor unit.
A terrace in Thornton Heath shares walls with its neighbours, which helps keep heat in, provided the outdoor unit can sit somewhere that passes the MCS noise check.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

How we price air source heat pumps
Jobs vary more than people expect. What affects the quote:
- Whether we need access equipment for high-level work
- A single visit or a regular plan
- The type of system, from a single split to a larger system
Homes, offices, shops and public buildings are all priced the same way: the equipment, the access, the work involved and the time it takes. Call for a fixed-price quote and we’ll go through it with you.
Helping us quote
When you contact us, these details help:
- A short video of any fault, such as a noise or a flashing light
- Your consumer unit or fuse board
- Your installation or service records
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and many jobs can be priced from that.
Rented and managed buildings
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to and we’ll copy in whoever needs it.
If you look after several properties, we can plan visits across the portfolio and price them together. Each property gets its own records, so each one has its own history.
How the job changes from property to property
Heat loss surveys
Getting the survey right avoids undersized or oversized systems and that matters for comfort and running.
The Boiler Upgrade Scheme
There’s one grant per property, and you cannot get a grant to replace a low-carbon system. Hybrids are excluded.
Heat pumps in Thornton Heath: local notes
About 53% of homes across Thornton Heath and its surrounding area were built before 1919, according to the Valuation Office Agency’s council tax figures, and about 39% of households live in terraced houses, according to the 2021 Census. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. In a terrace, the outdoor unit position and the MCS noise check need particular care. For a London home, the outdoor unit position and the MCS noise check need careful planning.
If you live near Thornton Heath station, the survey compares air-to-water and air-to-air for your home before anything is quoted. Kingswood House lies about 2.4 miles north-east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.

Thornton Heath: your questions answered
Can I have air conditioning in a flat in Thornton Heath?
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.
Is the heat pump grant available in Thornton Heath?
Thornton Heath is covered, as the scheme runs across England and Wales. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and is not an add-on to a boiler. The installer applies, and we’re MCS certified.
Do I get paperwork after the visit?
Yes. Every visit is written up, including F-Gas records for any refrigerant work. File them with the system’s paperwork.
Can I do the refrigerant work myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Will my radiators work with a heat pump?
Some radiators may be fine as they are, and some may need to be larger. Heat pumps run at lower flow temperatures, so radiators give out less heat, and the survey checks each one.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re also Checkatrade members.
Do you work on all makes?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.

How it works
Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. Then the electrics are made safe and the work begins. The work on site takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes, and we clear up before we go. Photos of the room and where the outdoor unit could go let us plan most of a visit to Thornton Heath in advance.
- It begins with your house and the heating it relies on now.
- Every room’s heat loss is worked out on site.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Then it’s fitted, commissioned and registered with MCS.
Before we arrive
- Mention any roof access, ladders or high-level work
- Find the manual or the paperwork for the system, if you have it
- Let us know where the consumer unit is
