How we handle air conditioning in Northfields
Thinking about air conditioning but not sure where to start? Send a few pictures of the rooms and the outside walls when you give us a ring on 07833 053749 or send an email, and we will reply the same working day about a survey or a fixed-price quote. Every installation in Northfields begins with a look at the rooms, the walls and where the outdoor unit can go, followed by a fixed-price quote with the brand, model and every part of the job set out.
In Northfields, as across London, the rooms that get hottest are usually under the roof or behind large sunny windows. A single wall-mounted unit in the worst room is often where people start, and a multi-split can cover more rooms from one outdoor unit where space outside is short.
Each manufacturer sets its own warranty period. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

When something else is needed
It’s worth knowing the limits before booking:
- Stuffy rooms that need fresh air rather than cooling
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- Building damp that has a structural cause
Not sure which it is? You can ring 07833 053749 or use the quote form and we’ll tell you honestly.
What the work covers
- Air-to-air heat pumps
- Multi-split systems
- VRF systems
- Ducted systems
- Ceiling cassettes
- Wall-mounted split systems
Aftercare tips
To keep the system working properly:
- Keep the indoor unit’s filters clean
- Flag any change in how the system sounds or performs
- File the paperwork with the manual
If anything is not right after we’ve gone, call us on the same number. Tell us what the system is doing, and any code on the display and we’ll help you sort it out.
Report drips, noises or error codes early. A drip, a noise or a flashing light is often an early sign of a fault and catching it early keeps the repair small.
How the visit works
We keep the work area tidy as we go, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. The visit takes anything from a day for one room to several days for a multi-room or ducted system. Let us know who controls access to the building in Northfields, as that saves time on the day.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Before it runs, the pipework is proved tight and put under vacuum.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Before we arrive
- Let us know where we can park and unload
- Tell us about any building rules, permits or sign-in
- Find the manual or the paperwork for the system, if you have it

Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and simple jobs can often be priced without a visit.

What the work involves, system by system
Multi-split systems
Two rooms on a multi-split are typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. The pipe routes to each room make the biggest difference to the price.
Ceiling cassettes
A cassette needs a void above the ceiling for the unit, pipework and drain, with a condensate pump where the drain cannot fall naturally. We check the ceiling void on the survey.

FAQs for Northfields
Can you do air conditioning in Northfields?
We do: Northfields falls inside our working area. Get in touch with the details and we reply the same working day.
Can I have air conditioning in a flat in Northfields?
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.
How quickly will you reply?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Will I get records for the system?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, while repairs and services get a written note of what was found and done.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it, and the quote is based on that.
What warranty do I get?
Warranty comes from the manufacturer and depends on the brand and product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
What does F-Gas certified mean?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
Air conditioning in Northfields: local notes
About 63% of homes in Northfields and the neighbourhoods around it were built before 1919, according to Valuation Office Agency council tax records, and the 2021 Census found about 36% of households in terraced houses. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. Terraces have little side access, so the outdoor unit usually goes on the rear wall or a flat roof, with the pipe run kept short. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
Boston Manor (roughly 0.5 miles south) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on. If you work from home near Brentford station, a home office that overheats is one of the easiest rooms to cool.
