Arrived to No Cool on 2nd floor System #1 : Model #TWE06044AAA03A00 Serial #20102751BA System #2 :Model #TWE06044AAA03A00 Serial #20101344BA Identified faulty remote temperature sensor on System #2. Reading 0 ohms of resistance through sensor. Replaced remote temperature sensor with System #1s remote temperature sensor to confirm fault, System #2 detected temperature and functioned as designed. Once system #2 was operating, identified low pressure lockout, identified belt had come off the indoor blower sheaves. Belt is in horrible condition, photo attached. Recommend replacing A42 belt. Put belt back on to test system, checked system, identified extremely low refrigerant levels, (diagnostics photos attached), identified two leaks in system. first leak identified in evaporator coil, coil is severely rusted, second leak identified on lineset, leak is on backside of horizontal portion of 90 degree elbow (photo attached). Factory charge is 10.5 pounds of R-410 based on system pressure

Returned to Replace filters and charge system with R22 refrigerant, replaced filters with 14x25x1, 14x20x1, 16x20x1, added 1lb of R22 to the system PSI 63/198, SH 14, SC 16, DeltaT 20, did not have to adjust blower speed at this time, system is running but due to age and condition multiple part failure is possible at anytime.

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

Call for Home inspection, Performed a Safety inspection on the the Heat Exchanger using a inspection camera and surfactant test and did not find a Compromise at this time, the Evaporator coil drain pan is rusted flushed water through to test if it is leaking and noticed water did start to leak out of the pan, the Aux. drain pan does not cover the entire Coil and would need a larger one.
Brad N.
