Really easy to work with- Willy found the leak in my unit, patched it, and filled me back up with refrigerant. He was able to come by only two days after I reached out and got the work done at a reasonable price. Highly reccomend

I've had Willy out at my house as well as at my business. Both times he was super honest, worked fast, and was very reasonably priced. Small shops like this win over the big companies every time.

It's not often. I will leave a review. The service has to be exceptionally great. Another HVAC company well-known royally effed up by HVAC when it stopped working and then they left me with no service just abandoning me. It was very cold. I had no heat. I googled HVAC service. Started going down every company on the list to find someone that could come out immediately. Calhoun was about my fifth call. Nobody else could get to me that day. Willy not only picked up the phone himself but he was on his way in 5 minutes or less. He and his assistant worked on my unit for the better part of 2 days. I expected a huge bill but it was half of what I expected. Calhoun mechanical is in my contacts under HVAC. Only company. I will ever be calling again.

10/10 service. Quick and easy. Super friendly and most definitely will be using them again

Really happy with the service provided - downstairs heating wasn’t working and unit was throwing a pressure switch/inverter error, Willy had Kieran come out to troubleshoot. After bypassing the pressure switch we were able to assess that the issue was with the inverter not working efficiently. Willy ordered the new part and installed the following day. Could not be happier with the prompt service provided.

Randomly found Callon Mechanical while looking for HVAC contractors, to look into why my newer HVAC suddenly stopped working, Willie was available right next day to go out and inspect, he found a power surge blew up the control board and a heating element. He kindly reminded me about the warranty I might have, which I found, he picked up the parts from warranty and installed promptly. HVAC works fine again. Courteous and timely.

Willy is the best local HVAC vendor in Nashville. Super responsive, nice guy and expert in his field. Willing to work on the weekend to repair what you need and reasonably priced. So much better than dealing with a large corporate HVAC company. Willy is more like your friend or neighbor that is helping you out. Highly recommend!
