Excellent workmen Excellent workmen; trouble with the office.

A very professional team of fitters. The fitters arrived on time and worked hard throughout the day, until they were fully satisfied that the unit was working as it should. They were very courteous and ensured that I was happy both with the siting of the unit and the operation of it. They worked very well as a team and afterwards left the room tidy and clean, as it was before. I can highly recommend this company.

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!
