"They were very attentive, and explained what they were doing as they went. I appreciated how quickly they would respond to my calls when the unit would break down again since it was during winter. They would usually show up later that day, or the next day or two if it wasn't an emergency. We ultimately had to replace our unit since they couldn't get it working again. Turns out our hvac unit was too big for the house, and the heat was backing up causing it to shut off due to a safety feature in it. Wasn't obvious at first, but they tried everything they could think of before deciding we had to replace it. I will definitely be calling them next time I have a problem.They ended up replacing our hvac unit &amp; modifying the intake vent. This was after several visits to try and diagnose the problem, and fix our current unit."
