What our customers say:

Feedback from just a small selection of our many satisifed customers.

The guys helped me choose which air con units would be best and gave me loads of advice on how to set the controls. Really professional and knowledgeable. Would definitely recommend.

Mr M Hove

I was thoroughly impressed with the service provided by Custom Climates. From start to finish, they were so helpful and full of advice about my new Daikin air source heat pump. Thank you for all the long phone conversations!

Mr P Horsham

Custom Climates installed 3 new AC units in our offices. They set the controls for us and talked us through the features. We were very pleased with them and will be using them for servicing next year.
