Ignoring These AC Noises Can Result in a Catastrophic Breakdown

You’ll hear your air conditioning system make slight sounds as it shut on and off. Depending on where you’re sitting or standing in your Durham, North Carolina, home, you might also hear it hum when it operates. But if you hear any one of the following four AC noises and ignore them, you could find yourself in an uncomfortable situation:


Your air conditioning system’s compressor sits outside. If you notice the outdoor AC unit making banging noises, it could be because of a loose fan blade that’s hitting against something in the housing. To avoid the worn fan blade damaging other parts, it’s imperative that you schedule a professional air conditioner repair right away.


A single worn fan blade won’t make rattling noises, but multiple blades can. Another air conditioner problem that can cause rattling noises in the outdoor unit is loose bolts or screws. A part that has a loose bolt or screw will eventually start to vibrate, which sounds like rattling. This can damage other parts and lead to significant AC repairs.


If you have leaks in your ductwork, you’ll notice your energy bills start to rise without reason sooner or later. But you’ll probably hear whistling noises coming from your air ducts before that. Fixing leaky ductwork isn’t an easy do-it-yourself AC repair. Therefore, you should always leave this job to a trained HVAC professional with experience.


Screeching is one of the most unpleasant sounds to the human ear. If you hear your air conditioning system’s indoor unit screeching or squealing, it likely has worn, loose or defective belts. A professional can replace them without hassle.

Ignoring these AC noises can result in catastrophic consequences, including the need for a premature air conditioner replacement. Contact Ted’s HVAC, Plumbing & Electrical today at (919) 823-7344 to schedule an air conditioner inspection right away.
