Uh Oh…Is Your AC Blowing Warm Air?


It’s one of the hottest days of the year and you just came home from work to a hot house. When you feel the air coming out of the vents, it’s hot. You run and check your thermostat to see if someone accidently turned the heat on, but to your surprise…your air conditioner is on at full blast. Now panic hits you as you have visions of an enormous repair bill or an unplanned replacement of your air conditioner.

What Should You Do
Hold on…take a moment, take a deep breath and perform a few simple steps before calling for service:

           Turn off the thermostat. You already checked to see if the heat is on, but check the temperature that it is set at. Reset the thermostat and lower the temperature to see if cooled air begins to flow through your vents.

           Look for a tripped breaker. Take a look in your circuit box to make sure the breaker for your air conditioner’s condenser hasn’t tripped. If it has, reset it and wait a few minutes to see if your air conditioner starts blowing cool air. If the breaker trips again, you should leave the air conditioner off and call for repair. You may have an electrical issue or the condenser might be overheating and then shutting itself down to prevent further damage.

           Check your air filter. Have you checked or changed your system’s air filter lately? During the hot summer months, you should probably be changing it at least one a month. If the filter gets clogged with dust or pollen, it will reduce the amount of air that is able to reach the coil in your air conditioner.

           Speaking of the coil. If you are able to access the coil inside your system’s air handler check to see if it is covered with dust or soot that can cause it to freeze up because of the lack of air reaching it.

           Look at the condenser unit outside. Check to see if tall grass or weeds are blocking air from circulating through the aluminum fins in the condenser’s cabinet. Remove the vegetation and any debris from the cabinet ONLY after turning off the power to your air conditioner from the circuit panel.
