The process
On the day, we arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. If your building in Coulsdon has a managing agent, a concierge or sign-in rules, mention them when you book.
- It begins with your house and the heating it relies on now.
- We measure heat loss for every room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- Cost, grant and VAT appear on one fixed-price quote.
- Then it’s fitted, commissioned and registered with MCS.
Getting ready for the visit
- Find the manual or the paperwork for the system, if you have it
- Plan for pets to be kept clear during the visit
- Let us know where we can park and unload
Getting a quote
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.
Advice
Air source heat pumps for homes and businesses in Coulsdon
A heat pump takes heat from the outside air and moves it into your home, using electricity to drive the process. It works on the same principle as air conditioning, run the other way, and air-to-air heat pumps are sometimes simply called air conditioning. Typical jobs include radiators that may be too small for a heat pump and moving away from fossil-fuel heating, on underfloor heating, air-to-water heat pumps and air-to-air heat pumps.
In a flat in Coulsdon, the lease and the freeholder normally decide where a heat pump can go. The planning rules for flats are stricter than for houses, and we check before designing.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

Air source heat pumps in Coulsdon: the local picture
VOA council tax data show about 38% of homes in the Coulsdon area date from 1919 to 1939, and about 62% of households live in detached or semi-detached houses, according to the last census (2021). Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Houses usually have space for an outdoor unit and a hot water cylinder. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Older homes near St Andrew's Church may need extra checks for planning and heat loss before a heat pump is designed.

Coulsdon questions
Can you fit air conditioning in a London flat in Coulsdon?
Often, yes, but the lease and the freeholder normally have a say. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Does the Boiler Upgrade Scheme cover homes in Coulsdon?
Yes, the scheme covers homes in England, including Coulsdon, if they qualify. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. You do not apply yourself: the MCS certified installer does, which is us.
Do you offer emergency call-outs?
Yes. There’s a 24/7 emergency line for breakdowns that can’t wait. Call 07833 053749 and tell us what’s happened.
Which type of heat pump is right for my home?
Air-to-water suits homes with radiators and a cylinder; air-to-air suits rooms that need heating and cooling. The survey helps decide. We install both types.
Will skipping a service affect the warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and explain why.
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
System by system
Air-to-water heat pumps
Air-to-water systems take heat from the air and put it into your central heating and hot water. It replaces the boiler as the main heat source, and is MCS certified when we install it.
Air-to-air heat pumps
Since 2025, air-to-air heat pumps can also be permitted development in England, subject to the conditions. Cooling-only units are not included and need a check with the council.
When something else is needed
Not every problem is solved by air source heat pumps, and we’d rather say so up front. It won’t put right:
- Draught-proofing and insulation upgrades
- Planning decisions, which rest with the council
- Grants for hybrid systems or replacements of low-carbon systems
If in doubt, call us on 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll say what we think.

What we are called out for in Coulsdon
Homes off the gas grid, heated by oil or LPG, are often good candidates to look at. Until March 2027, an extra £1,500 is available for air source and ground source heat pumps in homes heated by oil or LPG with no mains gas where the home is eligible.
These are the situations we see most often:
- Deciding on the outdoor unit position
- Choosing between air-to-water and air-to-air
- Questions about listed buildings or conservation areas
Historic houses such as Nonsuch Mansion, about 4.9 miles north-west, are a reminder that listed homes need consent before a heat pump goes in.
