Excellent service from Crystal Sigma
We have recently had 2 air conditioning units installed at home and we would recommend Crystal Sigma and their engineers to anyone looking to get an A/C installed in their home.
Both of the engineers we had install our units were very friendly, professional, and knowledgeable. They worked efficiently and tidily and were able to answer all of our questions.
A big thank you to James, David, and the rest of the Crystal Sigma team!

Diligent, Professional, Great Service!
Sam, Jamie and all of the team at Crystal Sigma have been extremely supportive and helpful through the entire process until completion. We had a tricky grade listed building to get AC for so the planning, design and commissioning process has been full of hurdles but the team have been very diligent and navigating through. Thanks Guys!
