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!
