My Air Conditioner Is So Noisy!
Posted: May 24, 2018 by Andy

"Why is my air conditioner making so much noise?" This is one of the most common questions customers ask us. Just like a car or truck, your AC unit is a sophisticated piece of equipment with numerous moving parts; if it's not working well, it can get pretty loud.

A noisy air conditioner can be caused by many different problems, depending on the type and age of your unit. Generally speaking, a change in the sound of your air conditioner is a bad sign. If your AC starts making harsh or grinding noises, there is probably something wrong, and it's time to give us a call.

Fixing a noise problem is usually relatively simple and low-cost, but beyond cleaning around the unit, it isn't something you should attempt to do yourself. Here are some common causes of a noisy air conditioner. We check for all of these and more during an annual AC tune-up!

Loose components

Rattling or banging sounds usually indicate that something in the system has worked itself loose. The outdoor condenser unit's housing screws could have backed out over the winter, or a piece of your home's ductwork could need reseated and tightened down. We'll inspect and tighten any loose internal and external panels, and we'll also make sure that your unit is installed correctly.

Condenser unit fan issues

If the air conditioner is making a whining or singing sound, one or more of its fan blades might be rubbing against the housing. Fan motors that are improperly or inadequately lubricated will hum loudly. Our expert technicians will diagnose and correct problems like this with the proper lubrication type and amount, or by replacing the motor itself when a lubrication problem has damaged it beyond repair. Either way, we'll ensure that your AC unit's fan motor is performing quietly and efficiently.

Bent coil fins

Your air conditioner's coil fins are somewhat delicate components that become clogged with dirt and get bent easily. Bent coil fins can cause a whistling noise and in severe cases can cause other components to rub against them, which causes even more noise and reduces their lifespan. Our comprehensive annual AC tune-up includes removing dirt and debris from your unit, cleaning it with a specialized chemical solution, and straightening any bent coil fins with a fin comb.

Aside from noise, why do you need an annual AC tune-up?
