Crystal Sigma Ltd

Extremely professional and responsive with very high standards, from Jamie’s planning and advice through to the installation. Great system and great guys. I’m very grateful after a disastrous experience with a competitor that shall not be named. It is so refreshing when things are done properly.

The installation of our Daikin air conditioning units by Crystal Sigma Ltd was excellent. Samir coordinated the installation brilliantly - his team were professional, clean and tidy and installed the units very painlessly in two days. Would not hesitate to recommend.

Excellent ! This is the second time I've used Crystal Sigma for a residential a/c installation in my own home. They are highly professional, easy to work with, prompt & thoroughly reliable. I will use again.

We had 2 twin units installed in one of our Colleges, the service from start to finish from Crystal Sigma was impeccable, they were transparent throughout the install, the quality of the work is second to none. Thank You for your service.

I was hugely impressed with the service; from obtaining the quote to the final install it was all completely painless and very quick. The installers on site were excellent, friendly and professional and extremely clean and tidy – we didn’t have to clean up after them at all. Overall very happy and would certainly recommend.
