    Why is my Goodman GPC 13 SEER H not cooling enough?
    • L
      laura56Aug 17, 2025
      Insufficient cooling in your Goodman Air Conditioner can stem from several issues. First, consider whether the unit is properly sized for the space. Recalculate the load to ensure it matches the unit's capacity. Next, check the airflow, which should be approximately 400 CFM per ton. Also, verify the refrigerant charge, following the procedure on the unit's service panel. Finally, ensure the voltage at the compressor terminals is within 10% of the nameplate volts when the unit is operating.

    Why is my Goodman GPC 13 SEER H compressor short cycling?
    • M
      Michael WellsAug 19, 2025
      Short cycling in your Goodman Air Conditioner's compressor can be due to a defective overload protector (replace and check for correct voltage) or the unit cycling on low-pressure control. Check the refrigerant charge and/or airflow to resolve this.

    What causes a Goodman Air Conditioner evaporator coil freezing or frosting?
    • A
      Adam LopezAug 22, 2025
      Evaporator coil freezing or frosting in your Goodman Air Conditioner can be caused by low airflow (check that it should be approximately 400 CFM per ton, and ensure air filters are clean and all duct outlets are open), low refrigerant charge (properly charge unit), or operating the unit in cooling mode below 65°F outdoor temperature (install or check low ambient control; it should be open below 65°F outdoor temperature).

    Why is my Goodman Air Conditioner's registers sweating?
    • J
      Jeremy RyanAug 26, 2025
      Registers sweating on your Goodman Air Conditioner is often due to low airflow. Increase the blower speed or reduce restrictions, such as replacing air filters, to resolve this issue.

    What to do if my Goodman Air Conditioner unit will not run?
    • C
      Charles LaraAug 27, 2025
      If your Goodman Air Conditioner unit won't run, check the following: * Verify unit voltage at the contactor. * Reset the thermostat if it's out of calibration or set too high. * Check the contactor for 24 volts at the coil and replace it if the contacts are open. * Replace any blown fuses or reset tripped breakers. * Check the transformer wiring and replace the transformer if defective. * Reset the high-pressure control or check the unit charge (high-pressure control opens at 425 psig, low-pressure control opens at 25 psig). * Replace the compressor, waiting at least 2 hours for the overload to reset.

    What to do if Goodman Air Conditioner compressor doesn't run but condenser fan does?
    • A
      Amy RiceAug 30, 2025
      If the condenser fan runs but the compressor doesn't on your Goodman Air Conditioner, check for the following: * Loose connections: Check for unit voltage at the compressor and tighten all connections. * Stuck, grounded, or open winding compressor: Wait at least 2 hours for overload to reset; if still open, replace the compressor. * Low voltage connection: Ensure voltage at compressor terminals is within 10% of nameplate volts when the unit is operating. * Defective capacitor: Check the capacitor and replace it if defective.

    Why is there high head and high or normal suction in my Goodman GPC 13 SEER H?
    • J
      Joseph Elliott MDSep 2, 2025
      High head pressure with high or normal suction in your Goodman Air Conditioner may be caused by a dirty condenser coil (clean it), an overcharged system (correct the system charge), or a condenser fan not running (repair or replace the fan).

    Why does my Goodman Air Conditioner have low suction and a cool compressor with an iced evaporator coil?
    • J
      Jennifer SantanaSep 5, 2025
      A low suction, cool compressor, and iced evaporator coil in your Goodman Air Conditioner are often due to low indoor airflow. To resolve this, increase the blower speed or reduce any restrictions, such as replacing air filters.

    How to fix high suction pressure on a Goodman Air Conditioner?
    • L
      Leah StoneSep 8, 2025
      High suction pressure in your Goodman Air Conditioner can be caused by an excessive load (recheck the load calculation), a defective compressor (replace it), or a reversing valve not seating properly (replace it).

    What causes low head and high suction in a Goodman GPC 13 SEER H Air Conditioner?
    • J
      Jill WilsonSep 10, 2025
      Low head and high suction in a Goodman Air Conditioner can be attributed to an incorrect flowrator (replace with the correct one), defective compressor valves (replace the compressor), or a flowrator not seating properly. For the latter, check for debris under the flowrator or a deformed flowrator; remove any debris or replace the flowrator.
