In an air conditioner, the capacitor is a small cylinder-shaped component that works with the blower motor, the compressor, and the outside fan in your unit.

Signs Your AC Capacitor Needs to Be Replaced

Your capacitor could start failing due to a number of reasons like extreme use, damage, or age. Below are some common signs your AC capacitor is going bad.

  • The system is not cooling your home
  • Your AC doesn’t turn on immediately
  • It doesn’t start at all
  • You hear a humming noise
  • The system turns on but the fan doesn’t
  • AC turns on and off randomly

Temperature and voltage greatly impact the lifespan of AC capacitors. If your unit runs at a high temperature and high voltage your capacitor is prone to failing more quickly. Dust and debris in the compressor unit can affect temperature. In fact, many failed capacitor issues are directly involved with blocked or dirty condenser coils because when the condensate coils are dirty, they cause the compressor to draw more amperage.

If you’re experiencing any of these signs with your system, it may be time to consult our expert air conditioning repair technicians. We’ll inspect your unit, diagnose the problem and fix it quickly and effectively so your unit can provide you with a cool and comfortable home once again.
