Installation work

Hidden Cool Ltd

We recently had Hidden Cool LTD install air conditioning in our three-bedroom house in Kennington, and we are really impressed with the results. Since we were restricted from having a bulky outdoor condenser, their internal-only Italian systems were the ideal solution for us. What we love most is how well the units are integrated into the walls; they almost feel like a part of the furniture rather than a typical AC unit. The installation team was fantastic—they were polite, incredibly tidy, and handled the whole process with a lot of care. It is a huge relief to have effective cooling that doe

Perfect internal AC solution—it looks like part of the furniture!

Fantastic experience with Hidden Cool. Our building has strict rules against external AC units, making cooling a challenge. They provided the perfect solution with their water-cooled internal units. The installation was seamless, and the system works perfectly without any outside equipment. From start to finish, the team was professional, tidy, and highly knowledgeable. If you live in a restricted building where external condensers aren’t allowed, I highly recommend Hidden Cool. A high-quality, professional job!

A lifesaver for our restricted apartment

I’m genuinely really happy with the work Hidden Cool did installing the AC units in my apartment in London. From the first message to the final handover, everything was handled professionally and with real attention to detail. They arrived on time, worked neatly, and clearly knew exactly what they were doing. The installation itself is super tidy, and they took the time to explain how everything works and make sure I was comfortable using the system before they left.

What I appreciated most was how smooth and stress-free they made the whole process — good communication, respectful team, and n

Exceptional service and high-quality workmanship

Stay away from this company!
They started a job at my home which proved to be a total disaster. Their work was terrible and all well documented. They admitted it was faulty and incomplete but instead of returning to rectify, they ran off with the money.
Apparently this is a pattern with them! 

STAY AWAY!

Hidden Cool provided outstanding service throughout our air conditioning installation. From the initial site visit, they were clear and thorough in explaining the entire process, which gave us confidence in their approach.

The installation took four days, and the team was professional throughout. They left the site neat and tidy at the end of each day, which we really appreciated. The quality of workmanship was evident in the finished result - the pipework and wiring for the condenser unit were installed very neatly.

Overall, a great experience and highly recommended.
