If your air conditioner starts acting up, one of the first things you should do is check the filter. If your HVAC filter is clogged with dust, it affects how well your AC works, and a dirty filter can even cause a breakdown. Your air conditioner might start working properly again when you put in a new filter, but if damage has been done, you'll need to call an HVAC repair service for help. Here are some repairs that could be needed due to a clogged filter.
1. Thaw And Clean The Evaporator Coils
When the filter is coated with dirt, the inside of the air handler gets dirty too. Dirt and grime build up on the evaporator coils, and that's not a good thing. Refrigerant flows through those coils, so if they're coated with grime, the refrigerant can't cool your home. Not only that, the situation can cause ice to form on the coils and then your AC won't be able to work and you'll have to deal with a watery mess when the ice melts.
Grimy evaporator coils need attention. This is a repair you can't put off because your AC won't be able to keep your home cool with coils that are in bad shape. An HVAC repair technician might be able to clean the coils with cleaning foam and a brush while they're still inside the air handler, but in extreme cases, the technician might have to take the coils out to clean them and that adds to the cost of the repairs.
2. Replace A Burned Out Blower Motor
Another part of the air handler that can get dirty is the blower. When the blower is coated in grime, it won't spin freely and that puts strain on the motor. This can cause the motor to burn out, and when the blower motor stops working, the air handler won't be able to blow air through the ducts and you'll be left without air conditioning. An HVAC repair technician can fix this problem by putting in a new motor.
3. Fix A Problem With Short Cycling
Short cycling is a problem that wears down your HVAC and drives up your power bill. Instead of kicking on and running several minutes before kicking off, your AC kicks on and off quickly when it short cycles. It does this because the HVAC overheats when it turns on and runs for a few minutes, so it shuts itself off to prevent damage to the equipment. A clogged air filter can cause this because of a lack of airflow. Other things can cause an HVAC to short cycle too, so the HVAC technician has to troubleshoot the equipment to find the cause. If the filter is the cause and no parts were damaged, simply changing the filter might solve the problem.
