Jim was great.
My technician was Jim Gauch. He wasn’t on the list of techs; he’s new! But Jim was great. Neat, clean, professional, very nice! Cleaned up after himself, friendly.
Barbara Cramer
Great job, Brian!
Great job, Brian! My water pressure in my geothermal loop was extra low. Brian quickly isolated the problem and fixed it.
Bob Sylvester
Knowledgeable and Efficient Technician
The technician, Alex and his partner, arrived during the given time window. He seemed very knowledgeable. I had a new Carrier HVAC system installed. He had a hard job as the HVAC system had to be installed in an unfinished basement with several very steep steps. He was efficient and quick. He took time after the installation to answer my questions about the HVAC and the new digital thermostat.
