I compared this company to 3 others. Sigma were competitive, responsive and delivered a good product. Would use them again

Great support overall from engineers to management. Quality products.Would recommend anytime.

They came up with the ideal aircon solution for my home. I did not have to wait long for the work to be done, and their customer service was excellent.

Impecable, profesional and polite

Excellent service and communication. Job was done swiftly with correct safety measures in place given the current environment. Very happy thanks!

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

Crystal Sigma is a very professional air conditioning company. They carried out the upgrading of our existing ac system with diligent workmanship and cooperative attitude and completed the contract work in a timely manner and to our full satisfaction. I wish they continue maintaining the high standard of their workmanship.

very efficient and value for money service and install

From point of contact to end of job, every interaction with a member of crystal sigma was professional and efficient. They are really helpful and would only ever use their services moving forwards

Excellent firm from start to finish. The job wasn’t as straight forward as we would have wished but the guys at Crystal Sigma found us the right solutions to make it works. I found them to be professional and trustworthy and fair - I can’t recommend these guys enough for all your AC needs.

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.

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!

amazing service from start to end, great company

Good guys installing.
We did have a few issues with some parts breaking early on, but they always came around either the same day or the next day to fix it, which i was really impressed with!

Very professional and prompt in sorting and fixing problems.

Would highly recommended, staff are great as well as being good with communication. The process was smooth and would deal with them again.

Crystal Sigma are really good firm where they are good at responding to us as soon as possible and get work action as quick as possible.

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.
