Common AC Noises and What They Mean in Tellico Plains, TN

You don’t want to ignore your air conditioner if it makes loud and unusual sounds. Even if the AC system still produces the set temperatures in your Tellico Plains, TN home, unusual noises are signs of trouble. Here are a few strange AC noises that you shouldn’t ignore, what they mean and some preventative practices:

Banging Noise

Banging noises are a telltale sign of a loose or broken part in the air conditioner, such as the piston pin or connecting rod. It could also mean that the indoor blower isn’t balanced, or you need to replace a faulty or worn-out compressor. Whichever the cause, hire a qualified AC repair service technician to inspect the unit, diagnose the issue to eliminate the banging noise.

Clicking Noise

It’s normal for an air conditioner to produce clicking sounds from the electrical components when stopping or starting. However, a continuous or constant clicking noise isn’t normal because it might indicate a failing thermostat or faulty control. Since the AC system has several electrical components, it’s vital to call a professional for inspection and early air conditioning repairs before the issues escalate.

Hissing Noise

Leaking refrigerant is often the reason for a hissing AC noise. Refrigerant leaks can damage the air conditioner and your family because the refrigerant is poisonous. You need a certified professional to fix the leak and refill the refrigerant because the unit needs it to operate correctly.

Squealing Noise

A high-pitch squealing sound might mean that the AC compressor is faulty, causing high internal pressure inside the air conditioner. A worn-out belt in the AC system’s outside unit is perhaps the reason behind a low-pitch squealing noise. Your AC service technician can easily replace the belt before it snaps and shuts down the air conditioner.

You need to act swiftly by calling an air conditioning repair service technician if you hear these AC noises. Routine maintenance, such as changing air filters and clearing debris, helps to reduce the number of AC repairs. Call Pol’s Heating and Cooling, LLC today to schedule an AC maintenance appointment.
