- Nancy M.

Air Conditioner Maintenance in Missoula, 59801

“Good afternoon, we would like to give Design Air and their staff an updated excellent review of their timely maintenance program on both our air conditioning and furnace systems. They installed our furnace system in 2019 and our cooling system a few years later. Both are operating as per factory specifications, so we are enjoying worry-free cooling and heating. Recently, Kyler was informative on what he inspected and tested, professional, polite, and respected our home by using shoe coverings which we greatly appreciated. He was friendly with our 13-year-old dog and described his own dogs which was very endearing to us. Overall, we appreciate Design Air and give them two thumbs up!”
