They were fast and reliable They were fast and reliable. I needed AC units installed asap and they were happy to help and do it in my timeline. They came recommended and they didn't fail to deliver.

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.

Excellent job by a professional team Excellent job and done on time and a good price. Any issues resolved quicky without impacting rest of the operation. Will use Crystal Sigma for future installations and also the maintenance contract is a must. Good job, well-done team. Happy customer. Definitely would recommend.

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
