Looking after your system
How well a system lasts depends on use and care. We suggest:
- Book a yearly service
- Ask about the grant before you commit
- Leave space around the outdoor unit
Equipment warranties come from the manufacturer. We explain the terms for your brand, including any servicing conditions.
Keep the outdoor unit clear of leaves, plants and stored items. Airflow is what it runs on, so keep it clear all year.
About our air source heat pumps in Crawley Down
Many air source heat pumps can be installed as permitted development in England, without a planning application. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit cannot be used solely for cooling or sit within the curtilage of a listed building. We check the rules for your property as part of the survey. We’re often asked to deal with working out where a cylinder could go and checking whether planning permission is needed, across homes heated by oil, LPG or gas, air-to-water heat pumps and radiator systems.
If your home near Crawley Down has no mains gas, the grant can be bigger. Homes heated by oil or LPG with no mains gas can get an extra £1,500 on the Boiler Upgrade Scheme until March 2027, for an air source or ground source heat pump.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork so it’s to hand next time.

What we do, step by step
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. On site, the work takes a few days for most air-to-water installations, with air-to-air systems often quicker. Let us know how to reach the outside wall or outdoor unit at your property near Crawley Down.
- 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.
- The job ends with commissioning, the MCS certificate and a walk through the controls.

Safe owner checks
Owner care supports servicing; it doesn’t replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
On air conditioning, the filters in the indoor unit are normally the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.

Common questions in Crawley Down
Can I get the Boiler Upgrade Scheme grant in Crawley Down?
Yes, the scheme covers homes in England, including Crawley Down, if they qualify. The amount depends on the type of heat pump, and the survey confirms which applies. As an MCS certified installer, we apply for it on your behalf.
Do I need planning permission for a heat pump in Crawley Down?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 4 buildings and structures within half a mile of the centre of Crawley Down. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with Mid Sussex council, which is usually the planning authority for Crawley Down first.
What does an air-to-water heat pump cost?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
Can I do the refrigerant work myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Do I get paperwork after the visit?
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.
What accreditations do you have?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re also Checkatrade members.
Can landlords and managing agents book you?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Crawley Down and across West Sussex. Let us know who the records should go to.
How the job changes from property to property
The Boiler Upgrade Scheme
There’s one grant per property, and you cannot get a grant to replace a low-carbon system, and hybrid systems are not eligible.
Radiators and underfloor heating
Underfloor heating suits a heat pump’s lower flow temperature, and we can connect to it where it’s already in.
Heat pumps in Crawley Down: local notes
About 78% of households live in detached or semi-detached houses, according to Census 2021 figures. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
If your home is listed, like Saint Hill Manor about 2.4 miles south-east, listed building consent comes before any heat pump work. Period properties close to All Saints Parish Church can suit a heat pump, though insulation and any heritage protection are checked first.
