Here's what some of our customers had to say...

Shaun Bell | Joshua James Jewellery Ltd | Hull and York

“I have used Caltech for over 10 years now for all of our air conditioning installations and maintenance. They are a highly professional family firm that have the ability to give the personal touch. I have recommended them time and time again and will continue to do so.”

Pam Dunn | Europa Crown Ltd | Hull

“Caltech offer competitive price and professionalism. They are always polite and work to a very high standard. Would highly recommend.”

David Giddings | Opulent Designs Ltd | Ilkley North Yorkshire

“Before the air conditioning was installed in the shop I was concerned about how much mess and disruption would be caused during the installation. In the event I was really pleased by the way they tidied up after themselves. Many Thanks.”
