Top Reasons Why AC Systems Vibrate or Shake
While every air conditioning system vibrates to some degree, that motion isn’t typically noticeable. The equipment works hard throughout the warm months of the year, but you shouldn’t see or hear the system operating. When there’s a problem with your air conditioner, however, you may notice your exterior unit or even a nearby wall vibrating when the system runs. You might even hear a shaking noise that raises alarm bells. What’s causing your air conditioner to vibrate?
Loose Parts
One of the most common reasons why an AC system vibrates is because parts are loose. Some of these parts could be screws, panels, or even the fan blade. Depending on the cause, loose parts could lead to significant issues like disconnected electrical wires, a malfunctioning blower wheel, or other problems.
Inadequate Sizing
When your air conditioner works harder than it was designed to, the extra effort can make the unit vibrate noticeably. One reason why your AC system might work harder is if it’s too small for your home’s needs. This might be because the unit was undersized at the time of installation or because your home’s square footage increased, such as from a renovation.
A Blocked Fan
Leaves, small twigs or branches, and other debris can find their way into your AC system’s exterior unit. When the fan moves, this debris can rattle against the metal. Depending on the type and amount of the debris, the vibration and noise caused by the blockage could be significant. Cleaning the exterior unit is an easy remedy to this problem.
Built-Up Dirt
Dust and other debris can also build up in the ducts and on the interior components. When this happens, your AC system won’t operate as efficiently as possible. As it works harder to compensate for poor efficiency, parts can wear out or become loose. The result in some cases is shaking.
Mechanical Problems
Numerous mechanical problems can also cause your air conditioner to shake. For example, if the motor’s rotor isn’t properly balanced, you might notice vibrations. Worn or loose motor shaft bearings can cause increased friction and shaking. Shaking can also be caused by the compressor or blower wheel.
Electrical Issues
Your air conditioner needs a reliable and adequate stream of electricity to function properly. Electrical flow could be impaired by faulty wiring or an inadequate or fluctuating voltage supply. Electrical issues should only be diagnosed and repaired by licensed professionals.
A vibrating AC system is more than an annoyance. It could signal a significant issue with your system that requires professional attention. For all of your AC installation and repair service needs, contact Ridge Heating & Air Conditioning in Panama City, FL today.
