air conditioner troubleshooting

Although the average air conditioner is designed to be trouble-free throughout its life, there’s always an exception or two. If you’re one of the few exceptions to the rule, then these air conditioner troubleshooting tips should help you get back to being comfortable as soon as possible.

Air Conditioner Troubleshooting

  • Make sure the air conditioner’s outdoor cabinet is clear of debris. When leaves and dirt pile up around the bottom of the cabinet, it prevents the condenser inside from receiving the airflow it needs to vent heat. Keeping this area free of debris is a simple way of fixing most A/C issues.
  • Make sure the ducts are free of debris. Even the best air filter won’t block every single speck of dust and debris. Over time, it can accumulate within the ducts and create airflow issues. Cleaning up the ducts can help restore your air conditioner’s performance.
  • If you’re constantly adjusting the temperature, try readjusting the thermostat heat anticipator. It’s usually set so that the unit cycles on before your home reaches an undesirable temperature.
  • Check the condensate pump in case of pooling water or humid air. A broken or unpowered condensate pump not only causes water spillage, but it also prevents the A/C from cooling effectively. A simple test involves pouring a small amount of water into the pan. If it doesn’t start when you do this, then the pump needs servicing or replacement.
  • Right-size the air conditioner.  Many air conditioning problems occur because the unit itself is either too large or too small for the space being cooled. If you've recently remodeled your home, then you may want to upgrade to a system offering the proper BTU for your home's square footage.
