We've been using One Hour Heating and Air Conditioning for so many years, I can't even remember how long. They've taken care of our heating and cooling for a long, long, long, long time! One Hour Heating has installed new units in our home, done repairs, and performed regular maintenance. They are always easy to reach, and responsive to our calls. The technicians show up promptly and are polite. They are also very careful not to make a mess. They wear little booties inside the house. If they have to go back out to their truck, the booties come off, then go back on. They are respectful as well as being good at their job! I highly recommend One Hour Heating and Air Conditioning! We are very satisfied with their work!
