Crystal Sigma Ltd

"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."

"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."

"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."

"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."

"I’ve not used the services of Crystal Sigma in a few years but they are still top quality and very reliable. The job turned out to be more complicated than originally anticipated but they still completed works in the agreed time frame with no question of additional charges - very impressed!"
