How we handle air source heat pumps in Hammer
A heat pump takes heat from the outside air and moves it into your home, using electricity to drive the process. The technology is close to air conditioning, which is why we install both, and air-to-air heat pumps are sometimes simply called air conditioning. The work covers air-to-air heat pumps, underfloor heating and radiator systems, and the jobs we see most are plans to switch to electric heating with a heat pump and choosing between air-to-water and air-to-air.
For a home around Hammer that is off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

What we do, step by step
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes from a couple of days to around a week, depending on the system and how much of the heating changes. For a village like Hammer, tell us about narrow lanes, gates and parking when you book.
- It begins with your house and the heating it relies on now.
- We measure heat loss for every room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- You get a fixed price, with any grant and the VAT set out.
- We install, commission and register the system under MCS.
Getting ready for the visit
- Mention any managing agent or landlord rules we need to follow
- Keep pets out of the rooms we are working in
- Make sure we can reach the outdoor unit, or where it will go

Advice
Heat pumps in Hammer: local notes
About 40 miles out from central London, Hammer is part of the South East area we work across.
Every heat pump design starts with a room-by-room heat loss calculation. Older homes near St. Stephen's Church may need extra checks for planning and heat loss before a heat pump is designed.
Hammer is about 9 miles south of Farnham, in Surrey. Whatever kind of property you have in Hammer, our engineers can help with air source heat pumps. You will hear back from us the same working day, and there’s a 24/7 emergency line. Count every place we list in Surrey and you reach 395, with Hammer on the list. The nearest of our city pages is Guildford, around 14 miles from Hammer.
Not far from Hammer, a recent job of ours was on Petworth Road, Haslemere (GU27), about 1 mile east: installing a Mitsubishi Electric multi-split system serving the master bedroom, two further bedrooms and the basement games room.
Our engineers cover all of GU27 and the roads nearby. You will find streets such as Hammer Lane, Moor Road and Copse Road, all of which are in our area. Close to Hammer, our area also takes in Woolmer Hill (1 mile south), Hammer Bottom (1 mile west), Shottermill (1 mile east), Bramshott Chase (1 mile north) and Linchmere (1 mile south-west). We also work in nearby towns such as Guildford (14 miles north-east), Farnham (9 miles north), Cranleigh (12 miles east) and Ash (11 miles north).

Locally, jobs take us to houses, flats and workplaces close to The Prince of Wales pub and Camelsdale Primary School, among other places.

Looking after it afterwards
Simple habits make a real difference. We recommend:
- Store the MCS certificate and warranty documents together
- Clear leaves and debris from the outdoor unit
- Ask about the grant before you commit
If anything does not seem right after installation, call 07833 053749 or email us and we’ll talk it through. Annual servicing helps keep the system working well.
Let the heat pump run steadily rather than switching it on and off as explained at handover.
Safe owner checks
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. Ask us to quote for a move instead.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and call 07833 053749 or write to us at info@aircondoctor.co.uk.
Rented and managed buildings
If you look after several properties, we can plan visits across the portfolio and price them together. Every address has its own paperwork, so the files stay tidy.
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.
Hammer: your questions answered
Will you come out to Hammer?
Yes, and the size of the place makes no difference to how we work. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is a heat pump in Hammer permitted development?
It depends on the property. The River Wey Conservation Area is close to the centre of Hammer. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask Waverley council, which is typically the planning authority for Hammer.
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’ll take it from there.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before booking and we will gladly show you ours.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, we work the same way: a look first, a fixed-price quote and written records.
What a customer said
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
