Why is My Air Conditioner So Loud?

We all love the modern convenience that is the air conditioner, but if your HVAC system is loud, it could leave you with a headache! There are many things that can cause your air conditioner to be louder than usual, but whatever the cause, the issue should be addressed right away.

Common Causes of Noise + How to Fix Them

A noisy AC is almost always a sign that something has gone awry within your HVAC system, so make sure you attend to the problem sooner rather than later. There are numerous things that can cause your air conditioner to operate louder than you’re used to, but these are some of the most common culprits:

A dirty fan: The fan is an integral part of your AC system and it needs to be kept clean in order for it to function. If your AC is louder than usual, a dirty fan may be to blame. To resolve this issue, simply open the air conditioner cabinet and locate the fan. If you see any debris or buildup on the blades, remove this first. It’s possible that the debris has found its way into the cabinet and is being jostled around. If this doesn’t resolve the issue, check to see if any of the fan blades are loose or crooked.

Loose screws: When your HVAC system is working, it tends to vibrate. This vibration, however, can cause screws to become loose and fall out. As loose screws are jostled around, they can make an unpleasant noise. Luckily, this is an easy fix and can be remedied by checking for loose screws in the panels throughout the unit.

Clogged coils: The coil fins are an important part of your HVAC system. Over time, these coil fins can become dirty and clogged, making the unit noisy as a result. If you suspect this is the culprit, clean the coil fins gently with a vacuum and brush attachment and remove any excess dirt or debris.
