I began having problems with a new HVAC/AC systems only a few months after purchase. The AC just stopped cooling. Shafer fixed it a couple times and it would work for a while. Finally on the Thursday before a three-day holiday it blew and wouldn’t stay fixed. Over the next four days, Shafer put in countless hours trying to solve the problem. Greg, Tom, and Steve were relentless. Finally, Steve found the culprit: a loose wire to the outside condenser. Their dogged pursuit of a tough problem was expert and well reasoned. They kept us informed throughout the process and maintained their senses of humor. Once again Shafer saved the day.
