How we handle air source heat pumps in Lumley
We begin with a room-by-room heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Guesswork leads to systems that are too big or too small. The work covers homes heated by oil, LPG or gas, air-to-water heat pumps and hot water cylinders, and the jobs we see most are radiators that may be too small for a heat pump and plans to switch to electric heating with a heat pump.
In a place like Lumley, some homes are listed, and permitted development does not cover listed buildings, so we check consent first.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

For landlords and property managers
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Tell us who the contact on site is and who should receive the paperwork, and we will keep everyone informed.
Portfolio owners often want one contractor and one number. We work across London and the South East, so work at different addresses can be planned together and kept on a regular cycle.
Safe owner checks
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. Ask us to quote for a move instead.
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
How the visit works
Each visit follows the same order: agree the plan on site, put the dust sheets down, do the work, check the system and explain it all to you. The visit itself takes a few days for most air-to-water installations, with air-to-air systems often quicker. A few photos help us make the most of a visit to Lumley.
- First we find out about the property, the heating you have now and what you’re hoping for.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Before we arrive
- Move furniture away from the wall where we will be working
- Let us know if the units are on a roof, a high wall or in a locked area
- Name a contact who can meet us at the agreed time
Ask for a quote
To help us quote: where the property is and what kind of building it is, a few photos, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Then ring 07833 053749 or write to us at info@aircondoctor.co.uk.

Common questions in Lumley
Is the coast a problem for outdoor units in Lumley?
It can, as Lumley is within about 1 mile of the sea, where salt in the air is hard on coils and fixings. The outdoor unit position, its fixings and regular servicing all help near the sea.
Can I fit a heat pump in Lumley without planning permission?
The answer turns on the property and where the outdoor unit would sit. Around 67 listed entries sit within 0.5 miles of central Lumley. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the local planning authority (for Lumley, normally Havant council).
How much time does a heat pump install need?
Expect it to take a few days on site, depending on the cylinder, the radiators and the pipework involved. How much of the heating changes decides most of the time and the timing is set out with your quote.
Will I get records for the system?
Yes. You get a written record of each visit, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
What warranty do I get?
Warranty is the manufacturer’s own, on its terms. Terms differ by brand, and we set them out on your quote.
Does the grant cover air-to-air heat pumps?
Only in limited cases, with a grant of £2,500. It has to replace the fossil-fuel heating, meet the full heating demand, be fitted by an MCS certified installer, and be in a home.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and tell you why.
Air source heat pumps around Lumley
At about 1 mile from the coast, Lumley is close enough for sea air to matter. Coastal sites are worth mentioning at the survey, as salt air affects the outdoor unit and its fixings. The 2021 Census found about 66% of households in detached or semi-detached houses. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
If your home is near Emsworth station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits. Warblington Castle lies about 1.6 miles west. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.

What the work involves, system by system
Heat loss surveys
Without a proper survey, a heat pump can be too big or too small, and both cause problems.
Air-to-air heat pumps
Air-to-air heat pumps are now covered by permitted development rules in England, subject to conditions. Cooling-only units are not included and need a check with the council.
