I have a heat pump on the roof. It is a Carrier from 1984. I have owned the house since 1993 and have replaced the contact breaker once and the condenser fan once. It is serviced annually. It has been super reliable regardless of age and therefor is somewhat of a freak. Location is Scottsdale AZ. Three weeks ago my tenant called to report the system was not blowing any air and the compressor was not turning on. Nothing, zip, nada. I called my tech of 18 years and he diagnosed a bad thermostat which makes sense. The system returned without any other requirements and ran like it always does without issue. Four or five days later the same symptoms return, the tech replaces the thermostat and the system returns without further issue. OK, maybe we got a bad thermostat, I guess it happens. Ten day pass since the replacement stat was replaced which brings us to today, Sunday at 6pm, and the tenant tells me we have the same symptoms again. Tomorrow the tech will be on the site to evaluate. Does anyone have any ideas should the stat be found out to be the culprit again? I mean, how unlikely is that! I cannot begin to imagine that the heat pump has anything to do with it. I am not a tech but I fully grasp the theory and mechanicals of how systems function. Thank you in advance.
