We’re Be Cool Refrigeration. Family-run, London-based, fitting commercial AC and refrigeration across the M25 since 2004. Our install team has done 2,000+ commercial fits. The store is new. The engineers behind every order are the same ones in our Google reviews. When you call 0203 488 1889, that’s who picks up.
Sourcing through a national distributor means 40 minutes on hold to confirm stock, a chatbot that can’t tell you if the indoor unit clears the soffit, and a quote that lands Wednesday afternoon. That’s an afternoon you don’t have on a job. We built this store so trade buyers stop losing days to the chain.
