"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!"

"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"
"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."
