Air source heat pumps in Fisher
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. It works on the same principle as air conditioning, run the other way and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. If you’re dealing with planning and permitted development questions and replacing a combi boiler with a heat pump, we can sort it out.
In a place like Fisher, some homes are listed, because permitted development doesn’t apply within the grounds of a listed building, so we check consent first.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

Pricing air source heat pumps in Fisher
We quote each job individually. This is what makes a difference:
- What we find on the survey or diagnosis
- Whether we need access equipment for high-level work
- The pipe route between the units
One room or a whole building, we price it on the same basis: what needs doing, how we get to it and what it needs. The price is fixed before work begins, with VAT shown clearly.
Before you get in touch
Good pictures often save a visit. The most useful are:
- A short video of any fault, such as a noise or a flashing light
- The fuse board and where it is in the property
- The outdoor side of the property, including any roof or flat area
Quotes don’t take long. Call or email with a few details and we’ll come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.
What air conditioning will not do
We’ll always give you a straight diagnosis, so here’s what air source heat pumps will not do:
- Planning decisions, which rest with the council
- Any gas work on the existing boiler
- Formal advice on VAT for your situation
If you are not sure, just give us a ring on 07833 053749 or email us and we will give you a straight answer.

FAQs for Fisher
Is the coast a problem for outdoor units in Fisher?
It can. Fisher is within about 2 miles of the coast, and salt air speeds up corrosion on outdoor units. The outdoor unit position, its fixings and regular servicing all help near the sea.
Is Fisher within the area you cover?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is there a Boiler Upgrade Scheme grant for air-to-air?
The air-to-air grant is £2,500, and only some homes qualify. It must replace fossil-fuel heating and meet the full heating demand of a home with an MCS certified installer.
Does servicing affect my warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we will tell you what your brand asks for.
Can I do the refrigerant work myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Will I get records for the system?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, while repairs and services get a written note of what was found and done.
Will my radiators work with a heat pump?
It depends on each radiator and the room it heats. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
What happens on the day
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. Anything unexpected is raised with you before we go further. From there, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Pictures of the space and where the outdoor unit could go let us plan the work in Fisher.
- We talk through your home, your current heating and what you want from a heat pump.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- You get a fixed-price quote, with any grant you are eligible for and the VAT explained.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
Getting ready for the visit
- Arrange for someone to be there to let us in
- Dig out any previous service or F-Gas records
- Mention any managing agent or landlord rules we need to follow

Other services in Fisher
Safe owner checks
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
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. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Air source heat pumps around Fisher
Fisher lies within about 2 miles of the sea. For a heat pump near the sea, ask about any coastal protection option the manufacturer offers. South Mundham Farmhouse, listed at grade II*, is one of roughly 4 protected buildings and structures in the half-mile around Fisher’s centre. For a heat pump, permitted development doesn’t apply within the grounds of a listed building, and in a conservation area the outdoor unit can’t go on a wall or roof facing a road, so we check with the planning team at Chichester council, which normally handles Fisher where necessary. About 56% of homes in and around Fisher date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and the 2021 Census found about 72% of households in detached or semi-detached houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Houses usually have space for an outdoor unit and a hot water cylinder.
Live in one of the older houses around St Leodegar's Church? Expect the survey to look closely at heat loss and at the building’s planning status. A heat loss calculation decides the size of heat pump your home needs.

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.”
