Don’t Install Rubber Gaskets or Use Old, Damaged Ones
When the outdoor AC unit is loud and vibrates excessively, it’s often due to faulty rubber gaskets. Outdoor units are exposed to the elements, including rain, sun, and wind, which can take a toll on the rubber gaskets over time.
Weather conditions can cause the rubber to harden, become brittle, or fail altogether, leaving gaps. Loose mounting screws, combined with the operating fan, can result in strong vibrations and loud noises. This issue can be resolved by replacing the rubber gaskets or tightening the mounting screws.

Outdoor Unit Requires Cleaning and Maintenance
Many households focus solely on cleaning the indoor evaporator unit, neglecting the outdoor condenser unit. This oversight can lead to a buildup of dirt and debris, especially when exposed to the outdoor environment. As a result, the internal machinery may not function smoothly, leading to unpleasant noises.
Foreign Objects in the Outdoor Unit
Sometimes, the source of the loud noises and strong vibrations is not limited to dirt and dust accumulation. Foreign objects, such as rodents, lizards, or other creatures, may find their way into the outdoor unit.
When these intruders get trapped and perish, they create an unpleasant odor and contribute to the loud noises. Addressing this issue is essential to ensure smooth and efficient operation.

Malfunctioning Condenser Fan in the Outdoor Unit
Issues with the condenser fan in the outdoor unit are common, especially during the rainy season. In such conditions, the fan operates continuously and is often exposed to rainwater.
This exposure can cause the internal oil to dry out, resulting in unpleasant noises. Additionally, the fan may become misaligned, causing it to spin off-axis. Another issue could be electrical wires touching the fan, creating unwanted noise.
