About us
Yes, it's really our name

Dang, It's Hot is named after our founder, Jason Dang. It's a pun, it's his surname, and it's the exact sentence every Londoner says three or four times each summer now. We figured a company should say what everyone's thinking.
Jason grew up in London, in homes like most of the city's: built to trap heat, because for a hundred years heat was the thing worth trapping. Then the summers changed. Top-floor bedrooms that never dropped below 28°. Fans pointed at beds. Sleepless August nights that everyone treats as normal, and shouldn't. British homes weren't designed for the weather they now get.
The answer most people reach for is air conditioning. What fewer people know is that the same unit, an air-to-air heat pump, also heats your home efficiently in winter. So we're not selling a summer luxury: we're fitting one system that keeps a room comfortable all year.
Getting it installed today usually means finding a local trade, waiting for a visit, getting a “quote” that's really an estimate, and hoping the day goes to plan. The installers are often skilled; the experience is stuck in 1995. We want it to feel as clear as ordering broadband. Your price online first, a proper survey to confirm it, a timeline you can see, and an install that's documented step by step.
We're starting small and local: our first homes are in a handful of London postcodes, few enough that every one gets our full attention. Longer term we want to look after the whole life of your system, not just the install day.
What that looks like in practice
Your price up front
You see a real price online in about two minutes, before anyone visits. A home survey then confirms it, and if anything changes, your proposal says exactly why.
A proper survey
We measure every room, photograph where the units and pipes would go, and check your fuse board, so your design starts from your house, not a guess.
One clear timeline
Price, survey, proposal, booking, kit, install, handover: every step on one page, with real dates and nothing marked done until it is.
Done properly, and written down
Every step of every install is photographed, measured and checked against a list. What we learn on one job goes into the checklist for the next.
Keeping London comfortable, street by street.
We're starting deep in a few postcodes rather than shallow everywhere. And yes, the dog in the drawing makes the important decisions.
