You can easily fix a noisy outdoor AC unit by following these simple tips. During the hot summer months, air conditioners are used more than ever. If your AC unit suddenly starts making unusual loud noises, check the outdoor unit for any issues before calling for repairs.
Missing or Old Rubber Padding
This is one of the most common reasons for a loud and vibrating outdoor unit. As it is usually placed outdoors, the components are exposed to harsh weather conditions, including rain, sun, and wind. Over time, the rubber pads (insulation pads under the base of the outdoor unit) may harden, crack, or even break, creating gaps.
Additionally, if the base-fastening screws are loose, the outdoor unit’s fan will vibrate and create noise. You can simply replace the rubber pads or tighten the screws to resolve this issue. However, if the installer forgot to install the rubber pads initially, it is indeed a serious oversight that needs to be addressed immediately. Having to fix such mistakes can be frustrating for many.
Neglected Cleaning of the Outdoor Unit
If the outdoor unit is not cleaned regularly, dust and dirt can accumulate due to its exposure to the outdoor environment. This buildup can lead to inefficient operation and unwanted noise.
Foreign Objects Entering the Outdoor Unit
Another possible reason for loud noises coming from the outdoor unit is the intrusion of foreign objects. This situation is similar to the third cause, but instead of dust and dirt buildup over time, there might be a sudden intrusion of an object, such as a mouse, lizard, etc., that gets stuck inside.
This can result in loud noises and unpleasant odors coming from the unit. If you suspect this has occurred, inspect and address the issue immediately.
Issues with the Outdoor Unit’s Fan
During the rainy season, the outdoor unit’s fan operates continuously and is exposed to rainwater, which can dry out the lubrication in the unit, resulting in annoying noises. Additionally, if the fan blades are damaged or broken, the fan will not spin smoothly. Occasionally, the indoor unit’s wires may also hit the fan blades, creating loud noises.
