We had the tech out because our thermostat stopped working. Turns out the failsafe had triggered a shutdown due to moisture and gunk in the system. We had had this system undergo routine maintenance in the spring and had to have someone else back out after we found it was leaking water. The tech today found that the failsafe had tripped because the system was not adequately cleaned. Our question is: Why, after a routine maintenance and a service call, was this missed twice? This visit cost us over $400, and while we are happy to have the A/C working again, we wonder if this was all avoidable.
