We got called to a restaurant on Mount Street last year. Michelin-starred, 90 covers, AC had gone down during a heatwave. Their previous contractor had been “servicing” the system for three years. We opened up the ceiling cassettes and the filters were original — never changed. The condensate drains had never been flushed. The condenser on the roof was so packed with pigeon feathers and grime that it was a miracle the system had lasted this long.
That’s a true story, and it’s not uncommon in this part of London. Mayfair and Soho are full of high-end businesses paying premium rents, but the HVAC maintenance behind the scenes is often shockingly poor. We’ve made it our business to be the contractor that actually does the work.
Mayfair and Soho sit side by side but they’re different worlds. Mayfair is Georgian townhouses, luxury retail on Bond Street, five-star hotels, private members’ clubs, and restaurants where the wine list has more pages than the menu. Soho is denser, louder, grittier — packed restaurant kitchens on Dean Street, bars on Old Compton Street, independent shops, creative agencies in converted Berwick Street buildings.
What they have in common is this: almost every building is old, space is tight, access is difficult, and Westminster Council has opinions about what you can put on the outside of a building. That combination makes HVAC work in this area genuinely specialist.
From planned preventative maintenance to handling urgent faults, our Mayfair and Soho engineers cover the full range of HVAC and refrigeration needs.
Most of Mayfair and large parts of Soho are in conservation areas. That means you can’t just bolt a condenser to the side of the building and run some pipes. The outdoor unit placement needs to consider sightlines, noise levels, and planning requirements. In some cases, you need a planning application just to install an AC system.
We’ve done this enough times to know the process. We specify compact, low-noise outdoor units — Daikin‘s Stylish series for smaller installations, or VRV units with acoustic enclosures for larger ones — and we know where to position them to satisfy both the client and the planning authority. Behind a parapet, in a lightwell, on a flat roof section that’s not visible from street level. Each building is different and there’s no formula.
If there’s one thing that defines our work in Mayfair and Soho, it’s restaurants. The density of restaurants per square metre in Soho is among the highest in Europe. Mayfair has some of London’s most prestigious dining rooms.
Kitchen ventilation is a constant conversation. Soho’s restaurants are typically crammed into tight footprints — a 40-cover restaurant with a kitchen the size of a large wardrobe, running a six-burner range, a charcoal grill, and a combi oven. The extraction system has to handle the heat load without being so loud that it disturbs the dining room or the neighbours. That’s a proper engineering challenge, and getting it wrong means a kitchen at 45°C during service or a noise complaint from the flat upstairs.
Commercial refrigeration in these restaurants ranges from small under-counter units to walk-in cold rooms squeezed into basements accessible only by a narrow staircase. We’ve manoeuvred compressor units down Victorian cellar steps that weren’t designed for anything wider than a wine barrel. It’s not glamorous work, but it’s the work that keeps these kitchens running.
AC for dining rooms needs to be quiet, effective, and invisible. A Daikin ceiling cassette in a Mayfair dining room can’t hum audibly — guests paying those prices expect comfort without being aware of the system. We select equipment with the lowest possible sound levels and commission it to run at the minimum fan speed that still meets the cooling load.
Mayfair’s office market is mostly boutique — small to medium floors in converted townhouses and mansion blocks rather than glass towers. The AC systems tend to be multi-split or small VRF installations, often with the outdoor units tucked onto the roof or into a rear courtyard.
Bond Street and Mount Street retail means luxury brands with strict climate control requirements — some fashion houses specify temperature and humidity ranges for their stock, and the AC system has to deliver that consistently. We work with several retail operators along Bond Street and New Bond Street on both installation and ongoing maintenance.
The hotels — from the large five-stars on Park Lane to the boutique properties on Albemarle Street and Half Moon Street — are a different proposition again. Guest room AC, kitchen refrigeration, ballroom climate control, back-of-house ventilation. A hotel is never just one system; it’s dozens of systems, all of which need to work simultaneously, and the guests shouldn’t know any of it exists.
We work from our Covent Garden office, which puts us within walking distance of both Mayfair and Soho. Our engineers know these streets. They know which buildings have rear access via the mews. They know that a Friday evening callout in Soho means navigating crowds that make driving impossible. They know that noise restrictions in residential parts of Mayfair mean some installation work can only happen during specific hours.
This isn’t a sales pitch — it’s the practical reality of working in one of London’s most demanding postcodes. A contractor who doesn’t know the area will spend half the job figuring out logistics that we’ve already got dialled in.
We’ve published practical guides on problems like air conditioning leaking water and AC thermostat reading wrong temperature so you know what to expect and when to call for help.
