"Excellent on-time service at competitive rates. I have used DT Air for years for everything from entire system replacements to semi-annual checkups and they have always been great to deal with."

"I had a great experience with Dana / DT during the estimate process and then Zee along with his team during the install. Zee and his team did a professional job explaining the install in detail and a little extra with a few issues they noticed during the install. I’d highly recommend DT air conditioning."

Googe Business Profile

"This is at least the 8th year of receiving 5 star service at a reasonable price from DT Air-conditioning and Heating for my personal residence and all of our rental properties.  They are the only vendor that Kapar Legacy LLC has used and not had any reason to change."
