Why Is My Commercial AC So Loud?

Loud units can be distracting and annoying. That is why it’s essential to know why your unit might be making more noise than it should. By understanding the causes of loud commercial ACs, you can take steps to correct the problem and enjoy a quieter office environment. In this blog post, we’ll explore why your AC might be so loud.

Loose or Broken Components

A commercial AC unit is designed to withstand a lot of wear and tear. Eventually, parts such as screws or fan blades can loosen, become unbalanced or break due to corrosion or general wear and tear. This can cause the unit to vibrate and produce unwanted noise.

Unlubricated Motor Fans

If your commercial AC sounds louder than usual, there’s a good chance that it’s because the fan motors are running dry. Fan motors rely on a thin layer of oil in the bearings to keep them running smoothly, but over time this lubricant can begin to evaporate. The motor begins to make noise as the moving parts start to grind against each other.

Clogging in the AC Unit

Leaves, branches, dirt and other outdoor debris can build up on the AC unit’s coils, fan blades and other components. This build-up can lead to a clog and cause the unit to work harder than it needs to, leading to increased noise levels.

Refrigerant Leak

One of the most common reasons for a commercial AC unit to be loud is a refrigerant leak for the AC unit. When the coolant level in the unit gets low, it stresses the compressor. When that happens, you may start to hear unusual noises.
