American Comfort Heating & Cooling is professional. They give you an estimate of the time they will need to do the work and they stick to that time frame. When they arrive, they are always on time. They let you know if they are delayed, and their communication is terrific. They are friendly and personable. We have a maintenance program where they check the heating and air conditioning unit annually. We are very pleased with the service thus far. American Comfort Heating & Cooling has shown us that this is a company we can trust and we are looking forward to their continued services.
