An office manager in a Farringdon serviced office block called us because tenants on the top floor were complaining about a grinding noise coming from above. It had started as a faint rumble a week earlier and progressed to a sound one tenant described as “like a shopping trolley being dragged across a car park.”...
A catering manager at a hotel in Kensington checked the walk-in freezer at 6am and found it sitting at -10°C. It should have been at -18°C. The HACCP temperature logger had been alarming since 2am but the overnight duty manager had silenced the alert thinking it was a glitch. Four hours of rising temperature with...
A deli owner in Islington sent us a photo of his serve-over display counter. The glass was completely misted up from the inside — customers couldn’t see a thing. He’d been wiping it down every twenty minutes during the lunch rush, but the condensation came back within five. His staff were opening the sliding doors...
A pub landlord in Bermondsey came down to the cellar on a Monday morning and found the beer lines frozen solid. The cellar thermometer read -2°C. Two casks of real ale had been ruined — frozen, expanded, and pushed the shives out. The keg lager was borderline. He’d lost a weekend’s worth of cask stock...
A head chef at a busy Indian restaurant in Brick Lane called us mid-service. Smoke from the tandoor was filling the kitchen instead of being pulled up through the canopy. Front-of-house staff were propping open the fire escape to clear the haze. Customers could smell it in the dining room. The extract system had been...
A restaurant chain asked us to investigate why their energy bills had increased by 25% across three London sites. No obvious faults — all the systems were running, all the temperatures were roughly where they should be. But “roughly” was the key word. Every system across the three sites was running 1-2°C warmer than set...
An office manager in Holborn described the problem perfectly: “The AC makes a noise like it’s starting up, runs for about two minutes, then clicks off. Five minutes later it does the same thing. It’s been doing it all day and the office is getting warmer.” That’s short cycling — the compressor starts, runs briefly,...
A hotel kitchen manager in Kensington called us worried about his electricity bill. It had jumped 40% over three months and he couldn’t figure out why. We found the answer in the basement — his walk-in cold room compressor hadn’t cycled off in weeks. It was running 24/7, pulling the temperature down to 1°C, then...
We get called to high-pressure trips more than almost any other refrigeration fault. A pub in Clapham, a restaurant in Soho, a cold store in Barking — the story is always similar. The condensing unit has been running fine for months or years, then one day it trips on the high-pressure safety switch and won’t...
A facilities manager in a Moorgate office block rang us in a mild panic because every indoor unit on three floors was flashing an error code simultaneously. Fifty staff sitting in a building with no climate control, the MD asking questions, and all the FM company could tell him was “it’s showing a fault.” The...
