Common AC Problems and Troubleshooting Tips

  • The AC Unit Won’t Turn On
    If your AC unit won’t turn on, the first thing to check is the thermostat. Ensure it’s set to “cool” and the temperature is lower than the current room temperature. If the thermostat is working correctly, check the circuit breaker to make sure it hasn’t tripped. If it has, reset it and try turning the AC unit on again. If the unit still doesn’t turn on, there may be a problem with the wiring or the motor, which will require professional assistance. You may need to replace your system entirely in some instances. In such a case, rely on our knowledgeable technicians for expert AC installation services in Garden Grove, CA. 
  • Poor Airflow
    If you notice poor airflow from your AC unit, the first thing to check is the air filter. A dirty filter can restrict airflow, forcing your AC unit to work harder, and potentially leading to more severe problems. Replace your air filter every one to three months, depending on usage. 
  • The AC Unit is Blowing Warm Air
    If your AC unit is mishandling warm air, check the thermostat first. Ensure it’s set to “cool” and the temperature is lower than the current room temperature. 
  • The AC Unit is Making Strange Noises
    If you hear strange noises from your AC unit, such as grinding, squealing, or rattling, immediately turn off the unit and contact a professional. These noises may indicate a serious problem, such as a loose or broken part, and should not be ignored.
  • Water Leaks
    If you notice water pooling around your AC unit or dripping from the indoor unit, there may be a problem with the condensate drain line. This line removes excess moisture from the air and must be clear to function correctly. Check the drain line for blockages and clean it if necessary. 
  • Frozen Coils
    If you notice ice on your AC unit, it may be due to frozen coils. A dirty air filter, low refrigerant levels, or a problem with the blower motor can cause this. Turn off your AC unit and let the ice melt, then check the air filter and refrigerant levels. 
  • Short Cycling
    If your AC unit turns on and off frequently, this is known as short cycling. A dirty air filter, low refrigerant levels, or a problem with the thermostat can cause this. Check the air filter and refrigerant levels, and make sure the thermostat is functioning properly. 
  • High Energy Bills
    If you notice a significant increase in energy bills, your AC unit may not function efficiently. A dirty air filter, low refrigerant levels, or a problem with the blower motor can cause this. Check the air filter and refrigerant levels, and consider scheduling maintenance to ensure your AC unit is functioning at peak efficiency.
  • Bad Odors
    If you notice foul odors from your AC unit, it may be due to mold or mildew growth. A dirty air filter, clogged drain line, or excess moisture in the unit can cause this. Check the air filter and drain line, and clean them if necessary. 
  • Uneven Cooling
    If some rooms in your home are colder than others, there may be a problem with the ductwork or the AC unit’s zoning system. Check the air vents in each room to ensure they’re open and unobstructed.
