I just had a very good experience with Mountain States Heat & Air. My old furnace was overheating and thermostat was not working properly. The service person George was very polite and pleasant to deal with. I was able to set up an in person inspection and appointment in a very short amount of time and in my convenience. George had deep knowledge of heating systems. He suggested the most cost efficient solution to my problem, fixed it quickly and in satisfactory manner. The best part was that he said my old system works just fine and only needs some tune up and some inexpensive parts. I am definitely calling him back if I need efficient cooling off in summer. Thank you for everything. Very satisfied customer. :)

Our air conditioner was making a loud unusual noise. I called George on Saturday. He had recently worked on our air conditioner for a different issue. He came between his other jobs and quickly diagnosed the problem. We needed a new fan motor. George said he would try and get one but there was only one supplier open on Saturday. He said he would be back on Tuesday if he could get the part. Of course the temperature has been in the 90s and would be for the next week. Later that same day George called and said he had the part and if we were home he would install the new fan motor. Within a couple of hours he had the air conditioner working and checked out. Again he did this between jobs. George could have just waited until Tuesday. George is very hard working and knowledgeable of what he does. He is pleasant and easy to work with. I would highly recommend him to anyone needing AC repairs.
