Customer mentioned after the storm, the thermostat has been a little finicky. It is a Goodman 2008 R22 system. Thermostat is currently working. Customer will hold off on replacing the thermostat. If it happens again, customer said she will replace the thermostat. checked electrical components temperature readings, and refrigerant levels. The unit is cooling well at this time. The indoor unit does have rust. The ductwork is older and has some tears added some tape to a few spots. I would consider investing towards a new system and ductwork.
