Excellent Products And Service

Dealing with Climatech was perhaps one of the best decisions I have made so far this year. From day one, when we received our quote, to post installation, this company has managed to live up to their word and our high standards. We replaced 14 windows and two entrance doors with Climatech. The process was extremely smooth. At no point were we rushed to make a rash decision of any sorts. The installation was scheduled four weeks after we signed the contract. The date was honored, and everything was completed within a few hours. Special thanks to Alex’s installation crew for the amazing job that they did.
