Air source heat pumps around Rowley Green
About 41% of homes across Rowley Green and its surrounding area date from 1945 to 1972, according to VOA council tax data, and about 38% of households live in terraced houses, according to the 2021 Census. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Live in one of the older houses around Holy Cross? Expect the survey to look closely at heat loss and at the building’s planning status. Historic houses such as Wyllyotts Manor, about 3.7 miles north-east, are a reminder that listed homes need consent before a heat pump goes in.

Air source heat pumps in Rowley Green, done properly
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales, and as the installer we apply for it on your behalf. Eligibility depends on the property, so we confirm it before anything is agreed. Common call-outs are for working out whether radiators need upsizing and questions about where the outdoor unit can go, on radiator systems, underfloor heating and hot water cylinders.
In a London area like Rowley Green, many homes are flats or terraces with little outside space, which affects which heat pump suits. An air-to-water system needs space outside and normally a hot water cylinder inside, while an air-to-air system needs less space.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

What owners can safely do
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and call 07833 053749.
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Managing agents and facilities teams in Rowley Green
Whether it’s one property or many, you get the same standard: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed-price quote.
After we have gone
Here’s the after-treatment advice, short and simple:
- Find out the grant position at the survey
- Seal draughts where you can
- Do not block radiators or indoor units with furniture
Now and then in cold weather, the outdoor unit defrosts itself. It may give off steam or sound different for a few minutes, and that is normal.
Keep insulation and draught-proofing in good order, as lower heat loss means the system has less to do.

Questions from Rowley Green
Does the Boiler Upgrade Scheme cover homes in Rowley Green?
Yes, the scheme covers homes in England, including Rowley Green, 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.
Do you cover Rowley Green for air source heat pumps?
Yes. Rowley Green is one of the places we cover. Just ring us on 07833 053749 or write to us at info@aircondoctor.co.uk with a few details.
When will I hear back?
On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.
What does F-Gas certified mean?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
How long will it take to install a heat pump?
It takes a few days for most air-to-water installations, with air-to-air systems often quicker. The cylinder, the radiators and the pipework make the biggest difference, and we confirm the timing with your quote.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we will agree what happens next.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
