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!

Have used these guy's on a number of… Have used these guy's on a number of occassions for new installs and repairs and found them to be reliable and tidy with their work. Easy to deal with and listen to what your requirements are to achieve a good result and very competitive prices.

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!

Well priced, helpful and friendly We got in touch after receiving a quote elsewhere we perceived to be extortionate. within days of enquiring, Crystal Sigma were in the premises and produced a quote which was far more competitive. Following that within a week or so we had the Unit fitted. Very pleased with the service from the office staff as well as the two guys who fitted the unit. Very impressed with the entire service
