Arrived to no cool System is an early 2000s model ( data plates are all faded and rotted ), York , gas heat unit. Indoor blower motor has been replaced and motor is hard wired to high voltage, fan runs continuously. Inducer motor is hard wired to high voltage and runs continuously. None of these faults will have a huge impact on overall cooling. Tested system from thermostat in cooling and system energized. System is slightly ( 1-2 lbs ) low on R22 refrigerant and fan speed could be adjusted up one speed tap. The major fault with the equipment was the filters. Extremely impacted and hadn’t been changed since 2019 which was greatly reducing airflow into the building. Filters have been removed. Filters required (1) 14202, (1) 14252, (1) 16202 System is currently cooling with a 24* temp split between return and supply

Arrive to No Heat Call mechanical heating components of failed. Heat exchanger is cracked to the point you can see daylight through the metal tubing. The front plate of the heat exchanger behind the burners is completely rusted. The inducer motor housing is rusted to the point that the mounting hardware is falling apart. The inducer motor is locked ( should draw no more than .50 amps, currently drawing .68 ) and the inducer fan will not turn. Tested in cooling, system functions as designed Disconnected heat wiring at control board. Cool and fan will still function. Model # KGA048S4 Serial # 5615G05263 System nor any components within system are under warranty
