After we’ve gone
Looking after the system is mostly common sense. Our tips:
- Check eligibility for the Boiler Upgrade Scheme early
- Diary the next service
- Leave indoor units unobstructed
After commissioning, the installation is registered under MCS and you receive the certificate. Keep it with the manufacturer’s paperwork for future reference.
Keep radiators and indoor units unobstructed so the heat can get into the room.
Air source heat pumps for homes and businesses in Chaldon
Every installation starts with a heat loss survey. That tells us how much heat the home needs, room by room, so the heat pump and the radiators or indoor units can be sized properly. Guesswork leads to systems that are too big or too small. If you’re dealing with finding a place for the outdoor unit and checking eligibility for a heat pump grant, we can help.
For a home around Chaldon that’s off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

Owner checks or an engineer?
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and call 07833 053749 or write to us at info@aircondoctor.co.uk.
On air conditioning, the filters in the indoor unit are usually the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
How it works
Protection comes first: sheets over the floor and any furniture nearby and nothing is moved without asking you. Then the electrics are made safe and the work begins. The work on site takes from a couple of days to around a week, depending on the system and how much of the heating changes, and we tidy up before we leave. We agree a date with you and plan the visit to Chaldon so we arrive with what’s needed.
- First we talk through the property and the current system.
- 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.
- Then it’s fitted, commissioned and registered with MCS.
Preparing for the visit
- Let us know if the building has a permit or sign-in process
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Make sure we can reach the outdoor unit, or where it will go

Chaldon questions
Will you come out to Chaldon?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and pictures, and we reply the same working day.
Does the Boiler Upgrade Scheme cover homes in Chaldon?
Yes, the scheme covers homes in England, including Chaldon, if they qualify. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. As an MCS certified installer, we apply for it on your behalf.
Which type of heat pump is right for my home?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms, and we help you choose. We install both types.
Who is responsible for leak checks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
How does the warranty work?
Warranty comes from the manufacturer and depends on the brand and product. For instance, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
Do you provide F-Gas records?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
Can landlords and managing agents book you?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Chaldon and across Surrey. Tell us who should receive the paperwork.
What a heat pump looks like in Chaldon
The 2021 Census found about 68% of households in detached or semi-detached houses. Houses typically have space for an outdoor unit and a hot water cylinder. In the mile around Chaldon’s centre, 2 conservation areas have been designated. Historic England lists about 3 buildings and structures within half a mile of the centre of Chaldon, including Rook Farm House (grade II). Where a home is affected, the outdoor unit position is settled with Tandridge council, typically the planning authority here before the heat pump design is finished.
A heat loss calculation decides the size of heat pump your home needs. 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.
