Very clean install in newly refurbished house Samir came up with the ideal solution for my house and Vali and his team did an impeccable job with the install. We were concerned as our house was recently renovated and AC was an afterthought, but Samir and Vali fit the system in a very clean and discreet way. We thought an AC install would be a large project and cause a lot of disruption but that was not the case with CS - highly recommended.

The service is very satisfactory The service is very satisfactory , finishing the job on time is not

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.

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

Recommendation I recommend Crystal Sigma
