Safe owner checks
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
About our air source heat pumps in Sewardstone
We install air source heat pumps in Sewardstone and across Greater London, and we’re 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. The work covers air-to-air heat pumps, homes heated by oil, LPG or gas and hot water cylinders, and people most often call us about finding a place for the outdoor unit and not knowing whether a grant applies.
A terrace in Sewardstone shares walls with its neighbours, which helps keep heat in, provided the outdoor unit can sit somewhere that passes the MCS noise check.
Aftercare is simple, and most of it is in the manual: 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.

What affects the cost of air source heat pumps
You will get a fixed price before we start. It’s based on:
- How easy the units are to reach
- What we find on the survey or diagnosis
- Which make and model is being fitted or worked on
No two properties are the same, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all make a difference.
Asking for a quote
When you contact us, these details help:
- A few pictures of the room and the wall the unit is on, or will go on
- Any error code or flashing light on the display
- Any previous service or F-Gas records
If you need air source heat pumps in Sewardstone, phone us on 07833 053749. Let us know the type of property and what you need, and send a few photos if you can. Enquiries get a reply the same working day.

FAQs for Sewardstone
Is Sewardstone in your area for air source heat pumps?
We do: Sewardstone falls inside our working area. Just give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk with a few details.
Do I need permission to put air conditioning in my flat in Sewardstone?
Usually, yes, though leaseholders normally need the freeholder’s agreement. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Are my radiators big enough for a heat pump?
Some radiators may be fine as they are, and some may need to be larger. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
Can I fit air conditioning or a heat pump 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 you survey before quoting?
Yes. We always look before we price, either on a site survey or from photos and details for simple jobs. A fixed-price quote follows.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We are also Checkatrade members.

Homes in Sewardstone and heat pumps
The Valuation Office Agency’s council tax figures show about 37% of homes in and around Sewardstone were built in 2000 or later. Newer homes typically lose less heat, which tends to suit a heat pump well. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
A heat loss calculation decides the size of heat pump your home needs. If your home is listed, like Forty Hall about 2.8 miles west, listed building consent comes before any heat pump work.

What we do, step by step
On the day, we arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes a few days on site, depending on the cylinder, the radiators and the pipework involved. If your building in Sewardstone has a managing agent, a concierge or sign-in rules, mention them when you book.

“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.”
