Why Did My AC Stop Working?


With the hot, humid summers in the Lakeland area, it can be very frustrating when your air conditioner breaks down, especially if you have to wait a while for repairs. While most problems should be handled by a professional, there are some simple things you may be able to correct yourself.

Common Causes of AC Breakdowns

When your air conditioner suddenly stops working, you may be able to save the hassle and expense of a service call by checking the basics first. Here are some of the common causes of breakdowns and some easy troubleshooting tips:

  • Wrong thermostat settings – If the settings on the thermostat were accidentally changed or the batteries are low, the system may shut off. Replace the batteries, if necessary, and verify that the thermostat is in cooling mode and set to the correct temperature.
  • Clogged filter – A clogged air filter or a duct obstruction can restrict airflow, causing the compressor to overheat and the system to shut down. Check the filter and replace it, if necessary. Make sure that none of the vents are blocked by furniture, drapes or other objects.
  • Tripped breakers – On especially hot days, excessive loads may cause the breakers for the air conditioner to trip. To restart the system, simply turn the breakers all the way off, then back on. If the breakers trip frequently, there may be a more serious problem.
  • Clogged condensate drains – As the air conditioner removes moisture from the air, it is drained away by the condensate system. If the condensate drain is clogged, a float switch may shut the system down. Check the condensate drain for clogs, and use a vacuum, compressed air, or a thin wire to remove any you find.
  • Blocked condenser – To remove heat from your home effectively, there must be good airflow over the outdoor condenser coils. Make sure there is no debris in the condenser, such as plastic bags or trash, and clean an area of two feet around the condenser unit of all debris to promote proper airflow.

If none of these tips help to restart your air conditioner, it may be time to call a professional to have the system diagnosed properly.
