Simply impressed and appreciative of Mountain States Heat and Air. They surpassed my expectations. George came over, inspected, and got my boiler heating system up and running in no time. After the system was up and running, he figured out, an air plug had developed in the top zone (I have a total of 3) He carefully inspected my system, and discovered it was in poor shape. (Just a little background: I have had it serviced every year, using the same company, and they always reassured me it was functioning optimally) George of Mountain State Heating and Air, pointed out each area of concern, and replaced valves, pipes, zone controllers. Not only that, he explained where each part was and its purpose, with some general upkeep information. It turned into a big job, but George did it correctly and with great integrity. MY HEATING HAS NEVER WORKED THIS WELL IN THE 5 YEARS SINCE I PURCHASED MY HOME!!!! Mountain States Heat and Air will be my exclusive heating provider!

Great work with steady communication throughout the repair. Was worried about having to replace an older central air unit. George found the problem and promptly fixed it at a fraction of the cost of a new one. I would definitely recommend him to anyone needing any type of HVAC service.

George was amazing. He was super skilled, very intelligent and very kind. He went out of his way to help us and we will always be indebted to him -our furnace would not work late at night and he drove 3 hours round trip at the end of his day to fix it for us. It was a very specific problem that was quite complicated but he went above and beyond by figuring out the solution and fixing it. THANK YOU to Mountain States Heat and Air, INC for keeping our family warm in the very cold.
