Signs You Need AC Repair Service

If you notice any of the below signs, it's essential to contact a professional HVAC technician from the Harkey team to assess and address the issues promptly, preventing further damage and ensuring the longevity of your air conditioning system. Regular maintenance can also help prevent many of these issues and keep your AC running smoothly. If you notice any of the following issues, give the Harkey Heating Cooling & Plumbing team a call:

  • Insufficient Cooling: If your air conditioner is running, but your home or space isn't cooling adequately, there may be issues with the cooling components, such as the refrigerant levels, compressor, or condenser.
  • Weak Airflow: Poor airflow from the vents could be a sign of a clogged air filter, a failing blower motor, or issues with the ductwork, all of which may necessitate repair.
  • Unusual Noises: Strange noises such as banging, rattling, or screeching coming from your AC unit may indicate mechanical issues, loose components, or a failing motor that requires attention.
  • Frequent Cycling On and Off: If your AC is cycling on and off more frequently than usual, it may be a sign of a malfunctioning thermostat, electrical issues, or problems with the system's sensors.
  • Leaking or Moisture Around the Unit: Moisture or leaks around the AC unit may indicate refrigerant issues, a blocked drain tube, or other problems that should be addressed promptly to prevent further damage.


  • Unpleasant Odors: Foul or musty odors coming from the vents may suggest mold or bacterial growth within the system, dirty evaporator coils, or other hygiene-related issues that need attention.
  • High Humidity Levels: If your AC is struggling to control humidity levels, it may be a sign of an undersized unit, a malfunctioning compressor, or issues with the refrigerant.
  • Visible Ice on the Unit: Ice buildup on the AC unit or refrigerant lines can indicate issues with airflow, refrigerant levels, or other components that may require professional intervention.
  • Increased Energy Bills: A sudden spike in energy bills without a corresponding increase in usage could be a sign of reduced efficiency, and your AC system may need tuning or repair.
  • Age of the System: If your AC system is aging and has not been serviced regularly, it may experience more frequent breakdowns and require repairs to maintain optimal performance.
