Help With Air Conditioning Problems: 3 Troubleshooting Tips That Work

Posted by Paul Wadsworth on Wed, Jun 19, 2013 @ 03:27 PM

Like any mechanical system, your air conditioner will eventually begin to show signs of wear and may start to malfunction. When your home cooling system gives you problems, here are some troubleshooting tips you can use to check the system out and possibly even get it running again:

Air conditioner won't start or run

  • help is on the way buttonCheck the basics. Make sure that both indoor and outdoor units have power and are working.
  • Make sure the A/C has been set to "cool" rather than "fan" or another setting.
  • Check the thermostat to be sure it has been set below room temperature.
  • Many thermostats operate on battery power, so make sure that the batteries are fresh and there is no battery icon showing on the display.
  • Check to see if any fuses have blown or circuit breakers have been tripped. Replace any blown fuses or reset breakers and try to start the A/C unit again.
  • Look over the wiring, plugs, switches and other components for visible damage.

No air, or not enough air, flowing from the ducts and registers

  • Check for problems in the ductwork system, such as blockages, bent or damaged ductwork sections, loose or missing sections or dampers that have been closed.
  • Make sure ice hasn't built up on the indoor cooling (evaporator) coil or near the air blower.
  • Check the unit's air filter to see if it's clogged with dirt and preventing air from flowing through it.

Not enough dehumidification

  • Check the room temperature to make sure it's falling.
  • Check the ductwork and airflow system for proper size and function. Often drapes, furniture or bedding is blocking the air vents.If your A/C can't get enough airflow, you may need to have a professional improve the air ducts.
  • Open interior doors so that the air conditioner is cooling a larger space.
  • Oversized air conditioners frequently fail to provide adequate dehumidification. An HVAC technician can help you determine if your equipment is too large for your home.
