Heat Pump Maintenance in Mt Sterling, KY 40353

“Just recently our heat pump needed a UV bulb replacement. John Winters was the technician that performed the replacement. He. Kept me informed of his arrival time, very much appreciated. While here he displayed a very professional appearance, positive attitude, and a good business work ethic. John seemed to be genuinely concerned about my system he was working on and was more than willing to address any and all concerns I brought up during his time here. I was very pleased with his knowleadge of my system and his openly friendliness. As a company employee, I’m sure he is a valued asset. I give him a 5 star thumbs-up.

Thank you for being such a good company.
