Cody call was at the end of the day. Despite this he was thorough in his review of our system and took the time not only to review the current issue of the internal fan not shutting off but also give me the tools, should the situation resurface, to detect if it is a thermostat issue or an electrical problems in the heat pump. He also did a quick assessment of our 15 year old system. A 5 star rating across the board from this guy. I will be contacting your team for all future heat pump needs.
