For this job we performed an evaluation. Upon arrival the unit was working within normal spec limits homeowner stated that sometime within the day the unit started working again. We could not get the unit to repeat the issue therefore could not diagnose what caused the unit to fail. No fault codes were noted during the inspection and all safeties were tested within normal limits. We recommended homeowner keep an eye on the unit and if the problem repeats to leave the unit as is so that we can reference a fault code and diagnose the issue properly. Thank you for choosing Comfort experts, have a great day!
