Brewer Heating and Cooling did a minor repair under extended warranty on a component that failed on a heat pump they installed 10 years ago, the first repair since installation. Service was quick, and professional. Their NATE (North American Technician Excellence) certification was one factor in selecting Brewer H&C originally. Short-cuts are more often taken than not in installation of HVAC systems, which can shorten the life of the system, and result in higher heading / cooling bills. Brewer mechanical did an exceptional job in installing the system per the proper procedures. They also listened to my concerns and issues I had with my original system (by another contractor) and addressed those in the new system. The result is after 10 years, the system performance as measured is as good as when it was installed.
