System by system
Radiators and underfloor heating
At lower water temperatures, radiators give out less heat so we check them against each room’s heat loss.
Hot water cylinders
Existing cylinders may not be suitable for a heat pump, and we explain whether yours can stay.
Air source heat pumps in Ewhurst
Every installation starts with a heat loss survey. That tells us how much heat the home needs, room by room so the system is sized to match. Guesswork leads to systems that are too big or too small. Typical jobs include wanting to stop using oil, LPG or gas for heating and an oil, LPG or gas boiler near the end of its life, across homes heated by oil, LPG or gas, underfloor heating and hot water cylinders.
Space for an outdoor unit is rarely an issue near Ewhurst, so the design focuses on heat loss and radiators.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

The 2021 Census found about 70% of households in detached or semi-detached houses. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
If your home is one of the older properties near Church of St Peter and St Paul, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Every heat pump design starts with a room-by-room heat loss calculation.

Your questions about air source heat pumps in Ewhurst
Can I fit a heat pump in Ewhurst without planning permission?
That depends on the building and where the outdoor unit goes. Central Ewhurst is a short walk from the Ewhurst Conservation Area. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with Waverley council, which is typically the planning authority for Ewhurst.
Will you come out to Ewhurst?
Yes, smaller places are covered as well as towns. A few pictures and the postcode are enough to get things started.
Can you set up regular servicing?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Do you work on systems someone else installed?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Is the equipment covered by a warranty?
Warranty is the manufacturer’s own, on its terms. Terms differ by brand, and we set them out on your quote.
Can I do any of the installation myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Who has to arrange F-Gas leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
What affects the cost of air source heat pumps
Every job gets its own quote. This is what makes a difference:
- How many units are involved
- The brand, model and parts involved
- The pipe route between the units
No two properties are the same, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all play a part.
What to send for a quote
When you contact us, it’s useful to have:
- The postcode and whether it’s a home, flat or business
- The outside wall, roof or yard where the outdoor unit sits or would go
- Photos showing the indoor unit and the space around it
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. After a look at the job, by pictures or a survey, the price is fixed. To get going, phone us on 07833 053749 or write to us at info@aircondoctor.co.uk.
Safe owner checks
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
What a customer said
“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.”
