This was the first time Brandon came out to do our regular maintenance and he was great! Checked everything and changed our filters. He was professional and efficient. Very nice too!


Excellent Installation




Review of Interstate Heating & Air Conditioning

I received quotes from three local HVAC companies, and Interstate was the only dealer who took the time to explain why they were proposing their system, and the different between the various systems. They were a bit higher, but they were more interested in doing the job correctly than lowballing it. Install took two days as predicted, and sales rep and installers were great to work with.


Typical friendly professional service.

I had been putting off having this service performed. Kianoosh explained everything perfectly and did a superior job. No regrets about having Interstate A/C perform this service for me. I would not hesitate to recommend this service to others.
