First of all, the guy that answered the phone on Thursday accessed my records and got the detail on my thermostat and tried to help me over the phone to save me needing a service call. It didn't work out but he tried and he got me someone to come next day rather than a Monday appointment. Then the repairman came and within just a few minutes discovered the trouble and resolved it. I'm only getting charged for the service call and 15 minutes of time. It couldn't have been a better experience.
