FAQs for Balham
Can you fit air conditioning in a London flat in Balham?
Typically, 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.
Is Balham in your area for air conditioning?
Yes, Balham is within the area we cover. To start, ring 07833 053749 or email us with a few photos.
Can air conditioning heat my home as well?
Yes, most modern split systems run as heat pumps, so they heat as well as cool. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. We confirm the heating function of the model we quote.
Can I have air conditioning in a flat?
That depends on the lease, the building and where the outdoor unit could go. An outdoor unit can sometimes go on a balcony, roof or rear wall, with consent and the survey looks at every option. This is general information, not legal advice.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
How does the warranty work?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for instance, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
What size air conditioning unit do I need?
Floor area is only part of it. Windows, the direction the room faces, the roof above and the people and equipment in it all count, and we take them all into account on the survey.
About our air conditioning in Balham
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, along with the manufacturer’s warranty terms on your quote. Air conditioning installation in Balham starts with a site survey, followed by a fixed-price quote with the brand, model and every part of the job set out.
Top-floor flats and rooms with big south- or west-facing windows tend to be the first to overheat in London. Many people start with one wall-mounted unit in the room that suffers most, while a multi-split serves several rooms from one outdoor unit, which helps where outside space is limited.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

Air conditioning in Balham: local notes
The Valuation Office Agency’s council tax figures put about 64% of homes in the Balham area before 1919, and about 63% of households live in flats, according to Census 2021 figures. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. For a flat, we look at balconies, flat roofs and rear walls for the outdoor unit, and the lease often needs checking first. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
Plenty of people near Balham station split the week between the train and a spare room, and that spare room is often the first to get a unit. Around Church of St Mary, a quick check of the listing and conservation maps is part of planning any install.

What else we do in Balham
Different systems, different jobs
Ducted systems
A ducted system needs a ceiling void or loft deep enough for the unit and ducts plus an access hatch for maintenance. We check that on the survey before recommending one.
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 route from the outdoor unit to each room is the main variable.
What you can do yourself, and what needs us
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo of the display helps even more.
Why act early in Balham
Fans and portables move warm air around rather than removing it. A fixed system removes the heat to the outside, runs more quietly in the room and can typically heat as well, so it earns its keep all year. In a London building, getting the freeholder’s or agent’s agreement can take a while, so it’s worth starting early.
Homes, offices, shops and public buildings are all priced the same way: what’s needed, how we reach it, the parts and the labour. Ask for a fixed-price quote and we’ll go through it with you.

The process
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then the work itself, and finally we test, record and explain. The middle part takes longest, and that takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Pictures of the space and the outside wall help us plan the work in Balham.
- First comes a site survey, or photos and measurements for a straightforward job.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- 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.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Preparing for the visit
- 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
- Keep pets and children away from the work area

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
