What we do: air conditioning and heating in London

We cover the full range of air conditioning and heating work short of gas and refrigerant jobs that legally require a certified specialist, and on those we bring in a Gas Safe registered engineer or F-gas certified technician as part of the same booking. Most clients call us about one of two things: a cooling problem in summer or a heating problem in winter. We handle both.

Air conditioning

• Split and multi-split air conditioning installation, including wall-mounted units for bedrooms, living rooms and home offices
• Portable air conditioning unit setup and exhaust hose fitting
• Through-wall air conditioning units for flats without outdoor space
• Air conditioning servicing: filter cleaning, condensate drain checks, gas pressure checks carried out by our F-gas certified technician
• Air conditioning repairs: units not cooling, leaking, tripping the fuse board, or making unusual noise
• Heat pumps that both heat and cool, a growing choice for London period properties with no gas supply nearby

Heating

• Radiator fitting, moving and replacement, including upsizing an undersized radiator in a cold room
• Thermostatic radiator valves (TRVs) supplied and fitted
• Radiator bleeding and system balancing when some rooms heat up and others do not
• Electric heaters and heated towel rails, wired or plug-in
• Underfloor heating repairs, including fault finding on electric mat systems
• Smart thermostats: Nest, Hive, tado and similar, fitted and connected to your heating zones

Gas boiler installation, servicing and repair is only ever done by a Gas Safe registered engineer. It is illegal for anyone else to touch gas appliances or pipework, and we will not pretend otherwise just to win a job. Likewise, any work on an air conditioning unit's refrigerant circuit, such as regassing or replacing a compressor, is handled only by a technician holding an F-gas certificate. We book these specialists in directly so you are not left chasing two different tradespeople.

Air conditioning and heating in London homes

London throws up problems that a generic air conditioning and heating guide never mentions, mostly to do with the building rather than the kit. A split system that goes in without trouble in a 1990s semi in Essex can turn into a three week negotiation in a Kensington mansion block.

Period properties

Houses in Chelsea, Notting Hill, Holland Park, Hampstead and Primrose Hill tend to have solid walls, original sash windows and, often, listed status or conservation area restrictions. Running refrigerant pipework through a solid wall needs careful routing to avoid damage to cornicing or original brickwork, and any external condenser unit visible from the street in a conservation area may need planning consultation before it goes up. We check this before quoting, not after installing.

Flats and managed buildings

In mansion blocks and managed apartment buildings across Marylebone, St John's Wood, Knightsbridge and South Kensington, the freeholder or managing agent usually has the final say on anything fixed to the exterior of the building. An outdoor condenser unit on a balcony rail or external wall is exactly the kind of thing that gets flagged. We always recommend getting written consent from the freeholder or management company before we install, even if your lease seems to allow it. A through-wall unit or a portable system avoids this issue entirely where consent is likely to be refused.

The most expensive mistake we see: a resident in a mansion block installs an outdoor condenser unit without freeholder consent, the management company issues a removal notice, and the owner pays twice: once for the original install, again to remove it and fit a through-wall or portable alternative instead. Always confirm consent in writing before any outdoor unit goes up, particularly in Belgravia, Mayfair and other managed buildings with strict exterior rules.

Access and parking

Terraced streets in Wimbledon, Fulham, Battersea, Clapham and Putney often mean no parking directly outside, and some boroughs run controlled parking zones that charge by the hour. We factor realistic access time into every quote so there are no surprises on the day. For properties in Canary Wharf and other high-rise developments, we also confirm lift access and any booking requirement for the goods lift before the visit, since that can add significant time to an otherwise simple job.

If you are also dealing with wider upkeep on the building, from gutters to decorating touch-ups, our property maintenance in London service covers the rest of the property alongside heating and cooling work.

How a visit works

You get a free quote in minutes, either by phone or through a short form describing the job and the property type. For straightforward jobs, such as fitting a smart thermostat or bleeding radiators, we can often quote and book from that description alone. For air conditioning installation or anything involving an outdoor unit, we usually ask for a few photos of the proposed location and confirmation of any freeholder consent needed, so the quote reflects the real job rather than a guess.

On the day, the engineer arrives in the agreed window, confirms the scope with you before starting, and carries out the work. If the job turns out to need a Gas Safe registered engineer or F-gas certified technician that was not part of the original booking, such as a leak that turns out to be a refrigerant issue rather than a loose fitting, we tell you before any extra work starts, not after.

For heating or cooling failures that cannot wait, our emergency handyman London service covers same day call-outs where availability allows.
