Your air conditioning system is the one appliance you rely on the most this time of the year. Your cooling system keeps you comfortable and refreshed through the long, hot, dry season that can often become unbearable. And it doesn’t just last a few months like it does in other parts of the country.

That being said, you’ll likely still be using your AC system for a while, and therefore you must address any problems that crop up right away to avoid a completely broken down system when you need it the most. There’s a certain sound in particular that should never be neglected—and that’s a banging noise. Read on to learn more.

Blower Fan

The motor of your system’s blower fan is located in the indoor air handler and is one of the most important components of the cooling system. The blower fan is tasked with extracting warm air from your home and sending cool air through the various air ducts in your home. The motor is vital to the functionality of your AC system.

If something goes wrong with the blower fan, such as a loose blade, the most common symptom is a banging sound. An issue such as this can create significant damage to your air conditioner, so be sure to call for repairs as soon as you notice the noise.

Compressor

Don’t neglect your outdoor unit. Inside this unit is your compressor, which is the heart of your cooling system. Banging coming from this part of the cooling system is typically indicative of a loose part or damaged fan blade. Or, it could be a sign of a problem with the compressor itself, like a loose connecting rod, piston, or other important internal part of the compressor.
