“Amazing service and courteous staff. All done in one day. Great communication from start to finish. They even refitted all my photos and pictures back to my walls in the exact same positions, attention to detail. 10/10”

“Harry and his team did an excellent job. They were very clear when spelling out our options, and the installation work was carried out promptly and very neatly. As promised, we can't see any cables without specifically looking for them.”

“From the moment Harry came to scope the work I knew we had the right guys. I was given all options and no pressure to go with them for the job. It was a big job, not rushed but also completed in a timely manner. Would highly recommend.”

The offer
A fan moves hot air around. It doesn't cool the room.
Most people put up with a hot bedroom for years because air conditioning sounds expensive and complicated. It's one system, one team and one price, and it starts at £1,400 supplied and fitted.
One price, one team. The unit and the installation quoted together, not as two separate bills.
The right size system. Daikin, Mitsubishi Electric and Samsung equipment, chosen for the room you want cooled.
Comfort all year. Every system HT Cooling installs is an air-to-air heat pump: cooling in summer, warmth in winter.
A finish you'd show people. Tidy pipe runs, hidden cabling and a clean finish in your home.

Coping vs cooling
The same hot room, two very different summers.
Fans and open windows
Air conditioning, properly installed
The site survey and the quote are free either way, and there's no obligation to book the installation.
What's included
Three parts, one company.
You don't buy a unit from one place and find a fitter somewhere else. It's handled end to end.
The right system chosen
We look at the room, the glazing and how you use the space, then recommend a system sized for it.
Supplied and installed
Indoor unit, outdoor unit and the work to connect them, agreed in one written price before we start.
Left clean and working
Tested, set up and shown to you properly, so you know how to run it from day one.
