We have had problems with are air many time, and we are always told that the problem is that we need a new unit. Witch has never been true. On the spot air come out within a hour of are call and fixed the minor problem immediately. Not only was there a quick resolution but are tech Wesley help me to understand what the problem was. Finally a company that isn't trying to sell us a new unit but fix the problem quickly with great customer service. So happy we have found On the spot air!
