“I have had IAQ to my home on two occasions. Both times it was well below zero outside and in the 40’s in our home. Pat was the technician on both occasions, he was very prompt, courteous and I knowledgeable. I now know more about two stage furnaces than i ever wanted to know. It is hard enough to find an honest HVAC contractor, we now have a furnace guy we can trust and will use them in the future. Thanks Pat.”
