Upon arrival spoke with customer and went to indoor unit. Pulled door off found no leaks on indoor coil, blower amped at 1.1amps. Coil was ice cold but felt hot on duct. Found white wire was getting call from state. Looked at stat and it is set up correctly. Explained to customer that the thermostat was bad. Also noticed no safety’s in system, priced up new stat, new safety’s, and also to pull white wire at unit so heat will stop. Customer explained he is going to fix it him self. System is working but not correct at this time.
