I arrived for a position call back on a system I recently repaired. I inspected the system and found the system to respond correctly with every command givin from the thermostat. I cycled the system milt times with the homeowner and we found the system to be running properly. I originally found the thermostat to be set on 67 deg. I set the thermostat to 70 deg to match the customers other thermostat settings. I did not charge the cups for this call but if we come back out for another no heat or no cool call there will be a diagnostic charge and repair charge or a test and verify if no problem shows itself.
