This is an excellent business to do business with! Michael came to our home and was knowledgeable and personable. The heating was not working properly in our home and the extremely cold weather would have us sleeping in the living room with a space heater tonight if Mountain Air hadn't came to our rescue. Tasha was kind and relayed our Winter emergency to the technician and all was well in no time. Thanks to the staff at Mountain Air/Ft. Smith, AR.
