Greater London · Air conditioning installation
Air con installers in Crooked Billet
We cover Crooked Billet for supply, installation and commissioning of air conditioning for homes and businesses, from one room to a whole building. Diagnosis first, a fixed price and proper paperwork when we finish.
- Expensive direct electric heating
- Rooms under the roof that stay hot into the night
- Fans and portables that do not keep up
After we have gone
How well a system lasts depends on use and care. We suggest:
- Report drips, noises or error codes straight away
- Book an annual service
- File the paperwork with the manual
The work area is left tidy: sheets removed, packaging cleared up and pipe holes sealed. Outside, the pipework is neatly fixed and protected as agreed on the survey.
Keep the outdoor unit clear. Anything piled against it, from leaves to garden furniture, reduces the airflow, which makes the whole system less efficient.
Air conditioning in Crooked Billet, done properly
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi are among the brands we fit. We recommend a model on the survey and explain why it suits the room, and the manufacturer’s warranty terms are set out on your quote. If you want air conditioning in Crooked Billet, one call covers the survey, the fixed-price quote, the installation and the F-Gas paperwork.
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.
Across London, and in Crooked Billet too, a lot of air conditioning goes into flats and terraces rather than detached houses. So the first questions are where the outdoor unit can sit, how the pipes get to it and whose permission is needed. In a flat, the lease and the freeholder typically come into it, so we write up the proposed positions for them to see.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

What we do, step by step
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. The visit takes anything from a day for one room to several days for a multi-room or ducted system. Pictures of the space and the outside wall help us plan the work in Crooked Billet.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- The quote is fixed and shows the equipment, where each unit goes and what’s included.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
Getting ready for the visit
- Keep pets and children away from the work area
- Arrange for someone to be there to let us in
- Clear a path to the units and the space around them
Ask for a quote
VAT is set out clearly on every quote, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. For a fixed-price quote, phone us on 07833 053749 or use the quote form.
Related advice
Do you need air conditioning in Crooked Billet?
Most overheating comes from heat gained through the day. Sun through large windows, roof lights and glazed doors is the biggest source in many rooms, and once the room has warmed up, it holds on to it into the evening.
Any of these is worth a proper look:
- Uncertainty over the right type and size of system
- Old electric heaters you’d like to replace with something more efficient
- Working from home in a room that gets too warm
If your home is in one of the older streets near Christ Church, it’s worth checking whether it’s listed or in a conservation area before an install.

When something else is needed
To be straight with you, there are a few things this work will not fix:
- Draughts and missing insulation
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
- A room that cannot take an outdoor unit or pipe route without the landlord’s, management company’s or council’s consent (that consent comes first)
Not sure which it is? You can call us on 07833 053749 or write to us at info@aircondoctor.co.uk and we will tell you honestly before you book.

What an install looks like in Crooked Billet
About 45% of households live in flats, according to Census 2021 figures. For a flat, we look at balconies, flat roofs and rear walls for the outdoor unit, and the lease often needs checking first. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
If you work from home near Raynes Park station, a home office that overheats is one of the easiest rooms to cool.

Common questions in Crooked Billet
Can you fit air conditioning in a London flat in Crooked Billet?
Normally, 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.
Do you cover Crooked Billet for air conditioning?
We do: Crooked Billet falls inside our working area. Tell us a little about the job and we’ll take it from there.
Where will you put the outdoor unit?
We agree it with you on the survey. It needs space around it to breathe and room for an engineer to service it, and walls or roofs facing a road can raise planning questions. We explain the options and any permissions to check.
Is there a survey before the work?
Yes. Every job is looked at first, on a survey, or from your photos and details where the job is simple. A fixed-price quote follows.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
