Homes in St John's Wood and air conditioning
The 2021 Census found about 88% of households live in flats. 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.
With historic houses such as Winfield House about 0.6 miles south-east, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

About our air conditioning in St John's Wood
Any installation we do in St John's Wood follows the same process as everywhere else we work: a site survey, or pictures for simple jobs, then a fixed-price quote, the installation, commissioning and F-Gas records. The price is fixed up front and the records are handed over at the end. A lot of the calls we get from St John's Wood are about one room that’s too hot to sleep or work in. A single-room split system is often the answer, from £1,200 + VAT.
London homes in St John's Wood can be short of outside space, so the outdoor unit may end up on a rear wall, a flat roof or a balcony. We look at noise towards neighbours and windows as well as looks, and the pipe run is planned to be short, neat and out of the way.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork, because it helps with any later warranty question.

Looking after it afterwards
Simple habits make a real difference. Our advice:
- Never run the system with the filters out
- Do not cover or box in the outdoor unit
- Keep to the service interval the manufacturer recommends
We recommend an annual service, and some manufacturers make regular servicing a condition of their warranty. We can remind you when it’s due, so it doesn’t get forgotten.
Book an annual service. A service cleans what you cannot reach and picks up faults before they stop the system and keeps the warranty paperwork right where servicing is a condition.
How it works
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work takes about a day for a single-room system, longer for multi-room and ducted systems. Send us a few phone photos and we can often price a straightforward job in St John's Wood before visiting.
- You send photos, or we visit and survey the rooms and outside.
- Each room is sized and the unit positions agreed, then you get a fixed-price quote.
- Sheets go down first, then the indoor unit and the condenser are mounted.
- Connections are made, checked for leaks and pulled down to a vacuum.
- The system is commissioned, the controls explained and the F-Gas records handed over.
Before we arrive
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Mention any roof access, ladders or high-level work
- Arrange for someone to be there to let us in

What affects the quote in St John's Wood
Your quote is based on your property. We consider:
- The size of the job
- What electrical work the job needs
- What kind of system it is
Our prices page shows typical ranges, but each job is priced on what it involves. For a fixed-price quote, give us a ring on 07833 053749 or use the quote form, and we’ll explain what it covers.
Asking for a quote
Simple jobs can often be priced from photos and some basics. Useful things to send:
- Wide photos of the room or the existing unit
- Any error code or flashing light on the display
- The postcode and whether it’s a home, flat or business
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.
Common problems we fix in St John's Wood
Bedrooms that are too warm at night are a frequent reason for a call. An open window does not always cool a bedroom that has warmed up all day, especially on a still night.
These are the situations we see most often:
- Rooms under the roof that stay hot into the night
- Old electric heaters you’d like to replace with something more efficient
- Not knowing which system, size or brand to choose
Close to South Hampstead station? A small study or box room used for work can usually be cooled with a single indoor unit.

- Whether they looked at the job before pricing it

Common questions in St John's Wood
Do you cover St John's Wood for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and St John's Wood is part of that. To start, call us on 07833 053749 or drop us a line with a few pictures.
Can you fit air conditioning in a London flat in St John's Wood?
In many cases, yes, once the lease and the building’s rules are checked. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Can air conditioning heat my home as well?
Yes, most modern split systems run as heat pumps, so they can heat a room in winter. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. Some cooling-only models exist, so we confirm it for the model on your quote.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.
Should I choose wall-mounted, ducted or cassette?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted units need a void or loft, and cassettes need a suspended ceiling, which we check on the survey.
Can I do the refrigerant work 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 protect the property while you work?
We start with protection: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
