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.

Highly recommended Crystal Sigma installed 2 air conditioner units in our house in London. We cannot be happier with their service and the final product. They were very easy to deal with, we had builders at home and they met with them and agreed on a plan to work together to install the units. Amazing job, thank you!

Excellent workmen Excellent workmen; trouble with the office.
