Removed old equipment and installed new Rheem 2 ston a/c with 90%+ gas furnace. Installed new supply plenum, new return plenum with 16x25x4 filter, new emergency drain pan, new pan safety switch, new drain line safety switch, new thermostat and new 8” return. Reconnected high voltage, low voltage, drain line, gas line, vent pipe and all duct work. Tested system operations in heating and cooling.

Upon arrival found office furnace flashing code “pressure switch open”. Inducer motor was hot to touch and not spinning checked amps 1.4. Removed inducer motor to check if anything had gotten into it, inducer and flue are both clear. Motor isn’t locked up but there is a lot of resistance when spinning the blades. Reattached inducer motor, inducer motor started operating however it didn’t sound normal and motor was starting to overheat. Inducer motor is failing. Photos and videos attached. Scoped heat exchanger and found that heat exchanger is compromised on right cell. Flames are fluffing and starting to roll out due to air getting into the exchangers via crack. Compromised heat exchangers have an increased chance of getting carbon monoxide into the air or having rollouts (when flames become unstable and “roll out” the furnace chamber) office furnace is beginning to roll out. Photos and videos attached. Need to replace heat exchangers and inducer motor or upgrade furnace for proper op

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
