What our customers say

Some of your neighbors think we're great.

“We had called one company prior to Desert State Air and they recommended full replacement. Javier with Desert State was out the next morning and they recommended just replacing the compressor and their price was lower and very fair.”

Carrie M.

“Mike and Sandy are the most caring business owners I have ever known. I've been their customer for over 20 years. My AC went out on a Sunday and in less than 24 hours, the problem was assessed and repaired.”

Paula E. · Facebook recommendation

“Mike was quick to respond. Very friendly, answered my questions and gave a competitive price.”

John B.

“Their quote was very much below the other quotes for the exact same equipment.”

Joyce M.
