- Deciding on the outdoor unit position
- Comparing heat pump types
The process
Our engineers arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. On site, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. For a place like Cranmore, the timing is set with you and the travel is our side of the planning.
- We start with your plans and the property.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We explain which type of heat pump suits the home and whether a grant could apply.
- The system is installed and connected to the controls.
- After commissioning, you get the MCS certificate and a handover.
Preparing for the visit
- Find the manual or the paperwork for the system, if you have it
- Arrange for someone to be there to let us in
- Let us know where the consumer unit is
How to get a quote
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price so you know the cost before we begin.

Air source heat pumps in Cranmore
An air-to-water heat pump heats water to a lower temperature than a typical boiler, so radiators may need to be larger to give out the same heat. The survey shows which rooms are fine and which need changes, and the quote sets it out. Typical jobs include deciding on the outdoor unit position and plans to switch to electric heating with a heat pump, across air-to-water heat pumps, underfloor heating and radiator systems.
Homes around Cranmore normally have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
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.

When to call us in Cranmore
Homes off the gas grid, heated by oil or LPG, are often good candidates to look at. The Boiler Upgrade Scheme includes an extra £1,500, until March 2027, for air source or ground source heat pumps in homes heated by oil or LPG with no mains gas where the home is eligible.
The things we’re asked about most are:
- Working out whether radiators need upsizing
- An oil, LPG or gas boiler near the end of its life
- Questions about listed buildings or conservation areas
With Swainston Manor about 3.4 miles south-east, it’s worth asking whether your own home is listed before planning a heat pump.
Questions to ask before booking
- If the quote is based on a survey, pictures or a diagnosis
- What records you get at the end
- Whether the electrical work is done by a registered contractor, such as NICEIC approved

Common questions in Cranmore
Is the heat pump grant available in Cranmore?
Yes, if the home and the heat pump meet the scheme’s rules: Cranmore is in England, where it applies. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. As an MCS certified installer, we apply for it on your behalf.
Does being near the sea make a difference to air source heat pumps in Cranmore?
It can, as Cranmore is within about 1 mile of the sea, where salt in the air is hard on coils and fixings. The outdoor unit position, its fixings and regular servicing all help near the sea.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
Does servicing affect my warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
How soon will you get back to me?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
How much time does a heat pump install need?
An installation takes a few days for most air-to-water installations, with air-to-air systems often quicker. The survey lets us set a firm programme, so phone 07833 053749 to arrange one.
Looking after it afterwards
Every system needs looking after, and most of it is easy. Our tips:
- Keep the MCS certificate with the manufacturer’s paperwork
- Keep the outdoor unit clear all year
- Diary the next service
Once commissioned, we register the installation with MCS and give you the certificate. File it with the warranty documents for future reference.
Keep the outdoor unit clear of leaves, plants and stored items. It needs good airflow to collect heat from outside so keep it unobstructed.
For landlords and property managers
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We can quote either party, and the paperwork can go to both.
Air source heat pumps in Cranmore: the local picture
Cranmore lies within about 1 mile of the sea. For a heat pump near the sea, ask about any coastal protection option the manufacturer offers. The centre of Cranmore lies within a conservation area. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where needed, we check with Isle of Wight council, usually the planning authority here. About 35% of homes in the Cranmore area were built before 1919, according to Valuation Office Agency council tax records, and about 87% of households live in detached or semi-detached houses, according to the last census (2021). Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. Houses usually have space for an outdoor unit and a hot water cylinder.
A heat loss calculation decides the size of heat pump your home needs.
