If you own a commercial building or large property in Phoenix, Anthem, or surrounding Arizona communities, a packaged rooftop AC unit is likely doing the heavy lifting when it comes to cooling. But what happens when that unit starts shaking, rattling, or vibrating more than usual?
A little vibration is normal. Violent vibration is not. In fact, it could be a warning sign that something needs immediate attention.
Why Do Packaged AC Units Vibrate?
Your packaged AC contains several moving components, including fans, motors, and compressors. Over time, wear and tear can throw these parts out of balance.
One common cause is a damaged or unbalanced fan blade. Even a small crack can create significant vibration as the fan spins at high speeds. Loose motor mounts can also allow components to move more than they should, creating excessive shaking.
Problems With The Rooftop Curb Mount
The curb mounting system acts as the foundation for your rooftop unit. If the mounting bolts become loose or the curb begins to deteriorate, vibrations can become much more noticeable.
Arizona’s intense heat and seasonal weather changes can cause materials to expand and contract over time. This gradual movement may weaken mounting points and allow the unit to shift during operation.
Compressor Issues Can Be The Culprit
Have you noticed loud humming or shaking when the system starts up?
The compressor may be to blame. As compressors age, internal components can wear down, causing excessive vibration. Ignoring this issue can eventually lead to expensive repairs or complete system failure.
Why Ignoring Vibrations Is Risky?
Many property owners assume a noisy rooftop unit is simply part of getting older. Unfortunately, that assumption can be costly.
Excessive vibration can damage electrical connections, loosen components, wear out motors faster, and even create structural stress on the rooftop curb. What starts as a minor issue can quickly turn into a major repair bill.
The Importance Of Professional Inspection
The best way to protect your investment is through regular HVAC inspections. A trained technician can identify loose components, worn bearings, failing motors, or mounting issues before they become serious problems.
