How it works
Where something has to be switched off during the work, we agree it with you first so it does not catch you out. In a business, work can often be done one area at a time. The work takes a few days for most air-to-water installations, with air-to-air systems often quicker. Photos of the existing unit and its label help with repairs and servicing near Knaphill.
- It begins with your house and the heating it relies on now.
- Every room’s heat loss is worked out on site.

- Cost, grant and VAT appear on one fixed-price quote.
- Installation, commissioning and MCS registration complete the job.

Air source heat pumps for homes and businesses in Knaphill
An air-to-water heat pump heats water to a lower temperature than a typical boiler which means some radiators may need upsizing. We check each radiator against the room’s heat loss and anything that needs changing is in the quote. Typical jobs include planning and permitted development questions and choosing between air-to-water and air-to-air, across air-to-water heat pumps, air-to-air heat pumps and homes heated by oil, LPG or gas.
Homes around Knaphill normally have space for an outdoor unit and a hot water cylinder, so heat loss, radiators and the electrics are what we check.
Nothing is signed off by word of mouth: 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.

Homes in Knaphill and heat pumps
Knaphill is about 26 miles from central London, well within the area we cover from our base in East Grinstead. Draw a one-mile circle round the middle of Knaphill and it takes in 2 conservation areas. Whitfield Court, listed at grade II*, is one of roughly 5 protected buildings and structures in the half-mile around Knaphill’s centre. Where a home is affected, the outdoor unit position is settled with Woking council, normally the planning authority here before the heat pump design is finished.
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.

Safe owner checks
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 ring us on 07833 053749 or email us.
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.

What happens if it’s left?
From 1 April 2027, VAT on heat pumps in homes rises from 0% to 5%. It’s a date to bear in mind when planning, though the right time also depends on your home and heating. A system that’s left with a fault, or without a service, normally costs more to run.
A single unit or a whole estate, the quote is built the same way: what needs doing, how we get to it and what it needs. The price is fixed before we start, and the quote sets out the VAT.

Questions from Knaphill
Can I get the Boiler Upgrade Scheme grant in Knaphill?
Knaphill is covered, as the scheme runs across England and Wales. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. As an MCS certified installer, we apply for it on your behalf.
Is Knaphill within the area you cover?
Yes. Knaphill is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Do you look at the job first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it and the fixed price is built on it.
What does F-Gas certified mean?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That is not optional: it’s required by law, and AirCon Doctor is certified.
Do I need to service the system to keep the warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we’ll tell you what your brand asks for.
A customer’s words
“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.”
