A Malfunctioning Blower Fan Could Be Why Your AC Has Ice on It

One of the AC services you could need is help with a frozen air handler. The air handler and the condenser can both get iced over when your air conditioner malfunctions. A few things can cause this problem, and one is poor airflow because the blower fan isn't working properly.

If you notice poor airflow before ice forms, you can have repairs done and save yourself the problems of melting ice dripping on your floor. Here are some signs of a bad blower fan and what an air conditioning repair service might do if your AC has ice on it.

Signs The Blower Fan Isn't Working

When the blower isn't spinning as it's supposed to, the amount of air coming from your AC vents is reduced. Without maximum cool air, your house doesn't cool down. Your air conditioner may need to run longer to trigger the thermostat to shut down.

If the problem goes on long enough, you might notice a higher power bill. A bad blower might also make noises that you're not used to hearing. If your AC runs, but it doesn't keep you very cool, call an air conditioning service to make repairs because the problem might get worse if nothing is done.

Reasons Ice Forms Due To Low Airflow

Your AC is designed to have a certain amount of air flowing over the refrigerant coil. If the airflow is low, the coil can get too cold and this can lead to ice formation because of condensation on the coil. Condensation naturally forms on the coil because the air that passes over it is warmer than the coil. The condensation keeps building, and if you don't catch the problem early, your evaporator coil can get covered in ice.

Ways To Deal With The Ice And The Blower

Once ice forms, you have two problems to deal with: ice and a bad blower. Call qualified HVAC contractors and let them know your problem. They might have you turn off the air conditioner and just run the fan so the ice can start melting while you wait for help.

The technician needs to repair the blower so the problem doesn't repeat itself. They may test all the parts that help the blower work such as the motor, fan, and wiring connections. Sometimes, the problem is an accumulation of dust in the blower. Once cleaned, the blower may start working again. If the motor is malfunctioning, the technician may need to put in a new motor so the blower has the power it needs to operate at maximum speed.
