Zach Pond1/28/2025 - I have used Callon a couple of times. The first job they did for me was replace a condenser. There was a factory defect in the unit and Callon solved the problem quickly. On the second job he worked on a very old package unit for me. I appreciate that he did not push to sell me a new unit. He informed me of the problem and reminded me my unit is ancient and gave me options to solve the problem. Then he let me decide.read moreread less

Cindy Holden5/01/2024I simply can't say enough good things for CM and Willy! The routine of HVAC technicians who spend the last ten minutes of their visit pitching various unnecessary products is exhausting. It's always a challenge to tell what actually needs to be done versus what they are trying to sell. However, Willy is a refreshing exception. He steers clear of any upselling, focusing solely on fixing what truly needs attention and generously offering advice on maintaining the system's performance. Easy to get ahold of, straightforward and local!read moreread less
