Customer called for AC out. Customer had a power outage yesterday afternoon and didn’t realize AC wasn’t functioning until they were in bed. System had multiple communication errors stored which is common with power out calls. Customer checked breaker and disconnect and both were good. They left stat in off position overnight. I turned thermostat to cool and system engaged inside and out. Checked outdoor pressures and they look great. Went over reset procedures with customer in case they have another power outage so they can get up and running sooner. Thank you!
