Cheyenne was very knowledgeable. Explained changes in a way that we totally understood the process.

It's the 2nd time Thermall has worked on my furnace. Had the same tech both times. No complaints…he was prompt and efficient.
I could do without the $189.00 service fee for it being a Saturday, but I guess that's how it goes

Mark was very timely, friendly, knowledgeable. He made sure that I understood everything and went above and beyond figuring things out. We have a delicate geothermal system and many outfits do not have the knowledge that it needs. He did a great job!

Every interaction I've had with them has been outstanding. They seem to really care about the quality of their work. Highly recommend!

Every time a technician comes out for service we have an excellent experience. They are friendly, professional, and knowledgeable. Before they leave we get a full report along with ideas to get the most out of our system. Thanks. You nailed it again yesterday!

Great crew! Fair price and great Installation!

Polite, helpful service people.


Excelente service!!!
