Air source heat pumps for homes and businesses in Harlington
We install air source heat pumps in Harlington and across Greater London, and we are MCS certified. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We help you work out which suits your home. Typical jobs include radiators that may be too small for a heat pump and questions about listed buildings or conservation areas, on radiator systems, air-to-air heat pumps and homes heated by oil, LPG or gas.
For flats in Harlington, the lease, the freeholder and the rules for flats all come into it. Permitted development limits are different for flats, so we check the position before we design.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

For landlords and property managers
Facilities teams in offices, schools and public buildings book us too in Harlington and across Greater London. Work can be phased by floor, zone or building around the people who use them.
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. Where a building is let or managed, the lease or contract should make clear who looks after the system and we’re happy to deal with whoever it is.
Air source heat pumps in Harlington: the local picture
About 49% of homes across Harlington and its surrounding area date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Osterley House lies about 3.6 miles east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions. 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.

Harlington: your questions answered
Can I fit a heat pump in Harlington without planning permission?
It depends on the property. There’s a conservation area, the Harlington Village Conservation Area, close to central Harlington. 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 the planning department at Hillingdon council, usually the authority for Harlington.
Does the Boiler Upgrade Scheme cover homes in Harlington?
Yes, if the home and the heat pump meet the scheme’s rules: Harlington is in England, where it applies. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. We hold MCS certification, so the application is ours to make for you.
Which accreditations do you hold?
As the law requires for refrigerant work, we’re an F-Gas certified company. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Will skipping a service affect the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Keep every service record either way.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll tell you what to do first.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.

What air source heat pumps can’t fix
Not every problem is solved by air source heat pumps, and we’d rather say so up front. It will not put right:
- Getting planning permission or listed building consent on your behalf
- A grant for a home that doesn’t meet the scheme rules
- Draught-proofing and insulation upgrades
If in doubt, phone us on 07833 053749 or use the quote form and we will say what we think before you book.
Where we work
- Underfloor heating
- Air-to-air heat pumps
- Homes heated by oil, LPG or gas
- Radiator systems
- Air-to-water heat pumps
- Hot water cylinders
The process
Protection comes first: sheets over the floor and any furniture nearby, and we ask before moving anything. After that, anything electrical is made safe and we start. 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. If your building in Harlington has a managing agent, a concierge or sign-in rules, mention them when you book.
- First, a chat about the property and your goals for the heating.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- The system is installed and connected to the controls.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Preparing for the visit
- Find the manual or the paperwork for the system, if you have it
- Mention any parking restrictions near the property
- Give us access to the outside wall, roof or yard where the outdoor unit sits
Getting a price
To get a fixed-price quote, phone 07833 053749 or write to us at info@aircondoctor.co.uk with the address and a few details about the rooms or units involved. A few photos make it quicker. We reply to enquiries the same working day.
Related advice
Keeping the system healthy
Aftercare is straightforward, and it makes the next visit easier:
- Clear leaves and debris from the outdoor unit
- Know the servicing conditions in your warranty
- Avoid switching the heat pump on and off often
Handover includes the controls and how to get the best from a heat pump. Steady running suits a heat pump better than switching on and off so we set the controls up with you.
Keep radiators and indoor units unobstructed, as the system relies on them giving out heat.

“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.”
