When I got bids for a new furnace/ac unit they were not the cheapest, but when I talked to them they were professional and knowledgeable. The other bids had widely varying sizes of equipment. Turns out after 10 years that Mountain hit it right on the button. I have them come around every year for a furnace tuneup. They check an amazing number of things. The only problem we did have, they fixed immediately. Steven, thank you for being so nice to work with.
