Several years ago when we were deciding on a new HVAC and meeting with several companies, we were most impressed with 72 degrees. Today, the technicians still provide great service. However, we have experienced quite a few challenges when contacting the front office to setup an appointment for a tune up. It takes an inordinate amount of time to locate or information and it doesn't always seem to be complete or accurate despite us providing corrections. This is annoying but not a deal breaker. We still plan to use 72 degrees in the future.
