Why is My AC Rattling?

Why is My AC Rattling?

When your air conditioner starts to make loud and funny noises, it can be a sign that it needs some attention. As a homeowner, hearing your AC rattling can be troubling and stressful. But a loud air conditioner is not uncommon. There are a number of different sources that can cause a noisy AC. Here are some of the most common reasons for these bothersome sounds.

• If you hear a rattling sound coming from the exterior AC unit, it is likely that something has simply fallen inside. Leaves, rocks, sticks or other parts of nature that get inside of the vents can cause this rattling sound. This debris can be damaging and requires attention as soon as possible.
• The most common cause of a rattling AC is that something is loose. Loose panels are another simple explanation for a loud air conditioner. The panels that house the condenser can become loose from screws that weren’t screwed in tight enough after repair. When an AC unit is working, it vibrates. These vibrations are what cause the screws to come loose. A simple fix in the mounting of the screws can ease your loud air conditioner.
• Poor installation or improper AC repair is another big issue that causes a noisy AC. If the refrigerant level is too high, it can cause problems that may damage destroy the compressor.
• Sometimes the misalignment of the blower can cause a rattling noise. If this is the case, a technician should assess the motor assembly because this can cause damage to the unit.

All in all, a rattling sound may not mean an expensive AC repair is headed your way. A simple tightening of a screw or a spring cleaning can ease the noise and your mind.
