Bone Up on Potential A/C Problems With This Guide

A properly maintained air conditioner (A/C) lasts for years, but issues can occur from time to time. Before you call a professional for service, troubleshoot to identify potential A/C problems you may be able to resolve yourself. Before you begin troubleshooting, though, check the thermostat to make sure it is set to “cool” and at a lower temperature than the actual room temperature. If you experience problems after this, it’s time to troubleshoot.

  • No power: Check your fuses or circuit breakers that power your air conditioner. Reset the breaker or replace blown fuses and your system should resume normal operation.
  • Refrigerant leaks: Low refrigerant levels typically result from improper installation or leaks. A certified technician should fix this issue and then properly charge your system.
  • Inadequate maintenance: Dirty air filters are a common potential A/C problem caused by poor maintenance of your system. Check your air filter at least once a month and replace or clean the filter if it is dirty to ensure efficient operation and to prolong service life.
  • Electric control failure: Over time, the compressor and fan controls can wear out. This is a common issue when the air conditioner turns on and off frequently, or if your central air system is oversized. Electrical problems should be inspected and addressed by a certified technician.
  • Sensor: The thermostat sensor in room air conditioners measures the air temperature to help the unit determine when it should turn on and off. If this is knocked out of position, gently bend the wire that holds it in place so the sensor is near the coil but not touching.
  • Drainage issues: Check the condensate drain to ensure your air conditioner is draining properly and is not clogged. If you have a room air conditioner, make sure it is mounted level so it can drain properly.

If troubleshooting potential A/C problems does not reveal the cause of your air conditioner system, call a technician for service.
