What causes high discharge pressure in Addison TRS?
- B
  Bianca CummingsSep 6, 2025
  If your Addison Air Conditioner has a high discharge pressure, several factors could be the cause. Start by checking the TXV setting and calibrate the superheat. Inspect the air inlet to the condenser for dirt or obstructions, ensuring proper clearances and checking for possible air recirculation. The condenser fan motor might be defective, so check the motor and run capacitor. Also, the condenser fan control could have an incorrect setting, so check the calibration of the low ambient head pressure control.

Why Addison TRS Air Conditioner compressor short cycles?
- J
  Jose MarksSep 5, 2025
  If your Addison Air Conditioner's compressor is short cycling, several factors could be the cause. Start by checking the thermostat's location and function, and verify the heat anticipator setting. An improper refrigerant charge could be the issue, so check the subcooling and verify the superheat. A defective high or low pressure control could also be responsible, so check the high or low pressure switch. Consider liquid floodback as a possibility, which can be related to tight bearings. Inspect the TXV and superheat for a defective expansion valve. Poor air distribution can contribute to short cycling, so check the ductwork for recirculating air. High discharge pressure can also cause this, as can leaking discharge valves in the compressor.

What causes Addison TRS Air Conditioner compressor to cut out on oil failure control?
- S
  Scott HollandSep 3, 2025
  If the compressor in your Addison Air Conditioner is cutting out due to the oil failure control, especially in semi-hermetic models, several issues could be the cause. Begin by checking the crankcase sightglass for a low oil level and add oil to bring the level to midway in the sightglass. A defective oil pump could also be responsible, so inspect the oil pump. The oil failure control itself might be defective, so check its calibration. Finally, liquid refrigerant entering the crankcase could be the issue; the compressor will be wet in this case, so check the crankcase heater or the cause for liquid feedback.

Why is Addison TRS Air Conditioner supply air temperature too high?
- J
  James NortonSep 2, 2025
  If the supply air temperature from your Addison Air Conditioner is too high, it could be due to several reasons. There might be a refrigerant undercharge or a leak in the system, so check the subcooling and look for leaks. The evaporator could be plugged with dirt or ice, so inspect the evaporator, airflow, and filter. The expansion valve might be improperly adjusted or defective, so check the superheat, adjust the TXV, and inspect the bulb. Also, the compressor itself could be defective, so check it for proper operation. High discharge pressure can also cause this issue. Check external static pressure because airflow may be too high.

How to fix noisy Addison Air Conditioner unit operation?
- A
  Allison BurnsAug 31, 2025
  If the Addison Air Conditioner unit is operating noisily, several factors could contribute to the problem. Check the blower, motor, and drive for faulty adjustment, noisy bearings, loose parts, or if the blower is out of balance, as these can cause blower rotational noise. Inspect the ductwork to ensure air velocity isn't too high, as this can cause air noise. Check for adequate control voltage, shorts or breaks, thermostat issues, and contact points to address chattering contactors. Finally, dampen tubing vibration by taping or clamping, and bend tubing away from contact points to resolve tubing rattle.

Why is Addison TRS compressor so noisy?
- S
  Stacey TownsendAug 28, 2025
  If your Addison Air Conditioner's compressor is noisy, several factors could be the cause. For scroll compressors, ensure correct wiring at the disconnect switch and verify proper evaporator blower rotation, as these compressors are rotation sensitive. Check the pressures and subcooling for refrigerant overcharge. Verify the oil level in hermetic compressors and check the total ecrankcase for excessive or insufficient oil. Inspect the TXV setting and check for refrigerant overcharge to address liquid floodback. Dampen tubing vibration by taping or clamping, and bend tubing away from contact points to resolve tubing rattle. If none of these address the issue, the compressor itself may be defective, so check internal parts on semi-hermetic compressors.

Why Addison TRS Air Conditioner compressor starts then cuts out on low pressure switch?
- B
  Brian MendezAug 26, 2025
  If the compressor in your Addison Air Conditioner starts but cuts out on the low pressure switch, it could be due to several reasons. Check the sightglass and pressures as there might be a low refrigerant charge. Inspect for restricted airflow, looking for a dirty evaporator coil or filters, closed dampers, iced evaporator, or issues with belt adjustment, motor amps, or duct design. Also, check for any restrictions in the liquid line by checking the head pressure and pressure drop across the filter drier. Finally, the low pressure switch might be defective, so check its calibration.

What to do if Addison TRS compressor starts but cuts out on high pressure switch?
- N
  Nancy WoodAug 23, 2025
  If your Addison Air Conditioner's compressor starts but then cuts out due to the high pressure switch, it could be due to several reasons. You might have a refrigerant overcharge, so check the pressures and charge by subcooling. The condenser fan control might have an incorrect setting, so check its calibration. The fan motor could be defective, so inspect it. Also, the condenser coil inlet might be obstructed or dirty, so check for clearances and air recirculation. Air or non-condensables in the system could also be the cause, so check the high side equalized pressure reading with the outdoor temperature. Finally, the high pressure switch itself might be defective, so check its calibration. Check for restriction in discharge or liquid line.
