During the hot summer months in Lost Creek, KY, we find solace in our cool air-conditioned houses. Occasionally, unfamiliar sounds emitted by the air conditioner can disrupt our moments of relaxation. Presented below are three unusual AC noises and their corresponding explanations:

Popping Noise

Loud popping noises from your air conditioner are likely due to issues with your ductwork, not the AC system itself. The popping noise can occur when the AC system starts or stops. This causes air to rush into or out of the ducts, resulting in popping sounds at the joints. While bothersome, this issue won’t harm your AC system’s efficiency or cause damage.

While addressing this issue, it’s also important to check the quality of your insulation. By using solid ducts and proper insulation, you can improve your air conditioner’s efficiency.

Squealing Noise

Squealing noises are often indicative of slipped blower or fan bearings. If the belt system is skipping, you may hear these squealing noises inside and outside the house. The motor bearing issue in the condenser fan leads to high-pitched squealing sounds in your air conditioner.

However, it’s important to note that older air conditioning models generally utilizes the belt system. More recent models usually employ direct-drive motors that don’t require belts. Repairing squealing sounds in your air conditioner is essential, regardless of its drive system.

Banging Noise

Banging provides yet another compelling motive to promptly shut down the system. It serves as a definitive indication that an internal component has become dislodged within the air conditioner. Regardless of the specific element, the air conditioning system relies on that part to operate effectively.

Banging noises spell trouble, signaling potential negative outcomes. Unsecured components can damage internal equipment, leading to fan malfunction or motor damage.
