Air conditioning installation in Keyhaven
Thinking about air conditioning but not sure where to start? Send a few photos of the rooms and the outside walls when you phone us on 07833 053749 or fill in the contact form, and you’ll hear back from us the same working day about a survey or a fixed-price quote. For air conditioning in Keyhaven, you get one team and one number from survey to sign-off, wherever you are in Hampshire.
Planning permission isn’t typically needed for a house if the unit qualifies as permitted development, but listed buildings, conservation areas and flats often need consent first: we flag that at the survey.
Space outside is rarely the problem in a place like Keyhaven. The questions are more often the age of the walls, the electrics and how far the pipes need to run.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Homes in Keyhaven and air conditioning
At about 1 mile from the coast, Keyhaven is close enough for sea air to matter. That is worth knowing for an install, as salt air speeds up corrosion on outdoor coils and fixings, so we choose the position and fixings with that in mind. About 71% of households live in detached or semi-detached houses, according to the 2021 Census. With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it.
If your home is in one of the older streets near Church of All Saints, it’s worth checking whether it’s listed or in a conservation area before an install.

What air conditioning will not do
Not every problem is solved by air conditioning, and we’d rather say so up front. It does not solve:
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- Damp from leaks or a lack of ventilation
- Work that needs permission from a landlord or the council

What else we do in Keyhaven
Before you call an engineer
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, 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.
Do not move, re-route or disconnect units or pipework yourself. 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.
Do you need air conditioning in Keyhaven?
Not everyone is after cooling. Direct electric heaters convert electricity into heat one for one, while an air-to-air heat pump moves heat from outside, which means more heat out than electricity in. That is how most modern split systems work.
Common reasons people call us are:
- Rooms that get too hot to sleep or work in
- Not knowing which system, size or brand to choose
- A home office that warms up with screens and equipment
A loft bedroom or a glazed extension is often the room that prompts the first call.

FAQs for Keyhaven
Will you come out to Keyhaven?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can I fit air conditioning in Keyhaven without planning permission?
That depends on the building and where the outdoor unit goes. Central Keyhaven sits inside the Keyhaven Conservation Area. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where necessary, we check with the local planning authority (for Keyhaven, normally New Forest council).
How does the warranty work?
Warranty is the manufacturer’s own, on its terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Do you survey before quoting?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
How long does it take to fit air conditioning?
Most single-room systems take a day. Multi-split, ducted and cassette systems take longer, and we tell you how long on the quote.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We are also Checkatrade members.
What we do, step by step
Where something has to be switched off during the work, we agree it with you first so it doesn’t catch you out. In a business, work can often be done one area at a time. The work takes about a day for a single-room system, longer for multi-room and ducted systems. If a lane or gateway near Keyhaven is tight for a van, let us know and we’ll plan for it.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Preparing for the visit
- Clear the space around the indoor unit, or where it will go
- Tell us about any building rules, permits or sign-in
- Name a contact who can meet us at the agreed time
