Why is My Air Conditioner So Loud?

Why is My Air Conditioner So Loud?

Air conditioners make noise because they are big machines with a lot of moving parts that make noise as they work hard to keep your home cool. But if the noise of your A/C unit has reached really high levels and you're reaching for the ear plugs, you should probably give us a call for HVAC maintenance. 

There are many noises your air conditioner may make that are completely normal. For example, older units are usually louder than newer units, and regular maintenance and tune-ups can help decrease the noise. Here are some of the most common A/C noises and some of the reasons your air conditioner might be so loud.

Rattling

A rattling noise from the outdoor A/C unit could be a sign that some leaves or sticks fell into the unit. Loose bolts, screws or fasteners could also be causing the rattling noise. A less common, but more serious, cause of a rattling sound could be the air compressor. As the motor in the compressor gets older, it might start making more noise, which is a sign that something could be wrong with it.

Grinding

A grinding sound most likely indicates a problem with one of the fan motors, such as a worn out bearing.

Popping

Popping sounds sometimes occur when the A/C unit is turned on or off. The popping noise is actually coming from the ductwork, not from the A/C. The sound is an indication that your ductwork needs repair or maintenance.

Hissing/Whistling

Hissing or whistling noises are also probably signs of problems in the ductwork. But if you hear hissing coming directly from the A/C, the unit may have a refrigerant leak, which needs to be handled by an HVAC professional right away.

Preventing Air Conditioning Noises

An easy step to prevent air conditioning noise is to regularly change the air filters. Keep a close eye on the filters, as they sometimes need to be changed more often than the filter manufacturer says. Clogged filters can hurt your A/C's performance, which can cause noises and other maintenance problems.
