Owner
Diamond Heating and Air just completed my HVAC project including heat pump/air handler replacement, attic sealing, new ductwork and new ceiling insulation. From the time Bob provided an estimate to completion of the project, they were thorough, very well organized, stayed on schedule and always cleaned their job site before leaving for the day. Bob, Elaine and his work crew kept me informed every step of the project. I highly recommend Diamond Heating and Air.
