Great people, Stephanie was wonderful! Answers the phone each time and we speak with real people! Highly recommended!

The owner (Ed) and techs (Eddie, Kirk) were professional and installation of equipment was excellent. We thank the entire staff for all their efforts!

— M. Neals

Our air conditioner was working on and off and Conn Mechanical was the only company that really came to get to the bottom of the issue. They stayed all day and got it fixed for us. Great service and smooth transactions with schedule and proposals to fix.
