"I signed up to have one of my HVAC's covered by Tim Kyle. I used the electrical service for over 20 years and the service is exemplary. This is the first time I used the HVAC service. I was impressed. It was a great job performed by a knowledgeable, pleasant tech who was available to answer any questions I had. Most important the HVAC was up and running before the 100 degree days to come later this week. Thanks guys"

"I called yesterday morning, got their answering service (since it was before normal business hours). The woman told me that someone from No-Frost would call me as soon as they opened for the day -- which is exactly what happened. Two hours later, I had a technician at my door. He was extremely polite and professional, and rapidly figured out what was preventing the HVAC system from heating the house. He performed the repair and explained to me what was wrong and what he was doing to correct the problem. I was very pleased with the responsiveness of the company and the competency of its technician."
