A loyal customer for past 16 years, I have purchased two systems for the old house and a new system last year for the new house. David gave me a good price and very pragmatic with no fanfare. Air and Heat hospital is customer orientated and providing top notch good service. Recently I have some problem with the A/C unit. They gave me excellent and speedy service on the same day. David, Michelle , Joe and Ken are to be commended. I am happy with them and will be customer for life. Thank you!!
