We had a new air conditioner and heating unit in our home. The previous air conditioner was 25 years old. The new one is an incredible upgrade from our old one. The installers were respectful as we were all home and careful (with masks) to keep us safe. They cleaned up all their discards (believe it or not, some installers do not clean up after themselves.) They covered our carpets with heavy floor coverings to keep it all clean. New heating and unit are great!!
