I couldn't be more satisfied with this company. They did everything they said they would and more. My 5 ton system went out so I started getting estimates. 7,8,9 thousand for a new system. Then I found Calahan. They got me up and running with a complete, nearly new two stage system for 3,600. I didn't have to break the bank or finance my life away for cold air, thanks to them! Highly recommend!
