Why Does My Air Conditioner Keep Shutting Off?

What can be more irritating than an air conditioner that suddenly turns off while enjoying some ice cream in your home or sleeping soundly? AC owners expect efficiency. There are a few common reasons for this problem, so you can fix it independently without contacting a technician for HVAC repair in Naperville, IL.

How to Tackle an Air Conditioner That Frequently Shuts Down?

  • Issues With The Thermostat: If your air conditioner unexpectedly turns off, it may be due to the thermostat. The thermostat controls when and how your air conditioner will work.
  • Dirty Air Filters: Dirty air filters are the main reason of several problems. When you contact a technician for help, they check your air filters first for cloggings. Dirty air filters will not allow your air conditioner to function correctly, no matter how efficient.
  • Refrigerant Leakages: When you hear a weird or hissing sound from your air conditioner, check the refrigerant levels, as there may be leakage. Refrigerant leakage will force your system to stop working.
  • Wrong Size: If your newly-bought air conditioner suddenly stops working, it may be due to size issues. A small air conditioner in a large room or vice versa will invite problems like unwanted breakdowns and short cycling.
  • A Malfunctioning Compressor: A compressor compresses refrigerant and takes it to the condenser to cool your home. If the compressor malfunctions, there will not be any refrigerant transfer, and the system may temporarily stop working.
  • A Faulty Capacitor: Capacitors act as batteries for the motors of the fans in your air conditioners. Capacitors give an initial kick to the engines so that the fans start circulating cool air in your home.
