Company are brilliant Company are brilliant, emailed them and got back to me straight away regarding attending a site and quoting the works that are required. Got a phone call after they surveyed site and advised they will send costs over which I received shortly after. They kept in contact after regarding any updates. Great company and very helpful.

Professional with a personal touch from… Professional with a personal touch from start to finish. The team explained everything clearly and enabled us to make the best decision for our property. They managed to squeeze installation in around a busy schedule at short notice. We have a newborn and we’re very worried about the heat in our bedroom - the engineers stayed beyond the end of their shift to make sure it was up and running. Essentially Crystal went above and beyond to help us out, and we are very grateful. I highly recommend them, and will do so to all my friends and family.

Recommendation I recommend Crystal Sigma

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!

5* Service, from a 5* Company! Professional, honest and reliable company that can not do enough to make your experience with them smooth and easy. Punctual, ensuring that they are always ready to start the job on time. Very obliging too with times and days. They keep to their word and know their stuff!
