About our air source heat pumps in Surrex
We begin with a room-by-room heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Sizing by rule of thumb isn’t good enough. If you are dealing with working out where a cylinder could go and deciding which kind of heat pump suits the home, we can help.
In a place like Surrex, some homes are listed, because permitted development does not apply within the grounds of a listed building, so consent comes first.
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.

Your questions about air source heat pumps in Surrex
Can you do air source heat pumps in Surrex?
Yes. We work across London and the South East from our base in East Grinstead, and Surrex is part of that. Tell us a little about the job and we’ll take it from there.
Is Surrex within the area you cover?
Yes. Surrex is within the area we cover across London and the South East. A few pictures and the postcode are enough to get things started.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
How does the warranty work?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for example, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
Can you set up regular servicing?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for problems that can’t wait for a planned visit. Call 07833 053749 and tell us what’s happened.
Why does F-Gas certification matter?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before you book and we will gladly show you ours.
Other services in Surrex
Owner checks or an engineer?
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.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
What we do, step by step
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work takes a few days for most air-to-water installations, with air-to-air systems often quicker. We agree a date with you and plan the visit to Surrex so we arrive with what’s needed.
- We talk through your home, your current heating and what you want from a heat pump.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.

When something else is needed

- Draught-proofing and insulation upgrades
- Planning approval where permitted development doesn’t apply

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
