What’s That Sound? 4 Noises Your AC System Shouldn’t Make

Depending on the age of your home and its layout, you’ll hear it make various sounds, especially at night. One of them might be your air conditioner turning on and off. But if you notice your AC system making loud noises, it’s an indication there’s a problem that needs resolving. Read on to learn four noises that should alarm you enough to schedule an air conditioner repair in Lombard, IL.

Banging

If you hear your air conditioner producing a banging noise, it’s probably because there’s a loose or broken part in the compressor. It could be a failing crankshaft, connecting rod or piston pin. An unbalanced indoor blower will also cause banging noises. In the worse case, the banging noise will signal you need to replace the compressor.

Clicking

Hearing a click as your air conditioner turns on and off is normal. But if you notice your AC system making a constant clicking noise, it’s time to investigate the matter. Clicking can signal that you have a defective thermostat or control. Repairing the electrical issue right away is critical to prevent more significant problems later.

Squealing

You might hear squeaks, squeals or rattles coming from your supply vents via the ductwork. This is likely because of failing fan and indoor blower motors. The blower wheel and housing will also cause a squealing noise if they start malfunctioning. The sooner you have this issue repaired, the lower your risk of a costly breakdown.

Screeching

If you hear high-pitched whistling or screeching, turn the AC system off right and contact a professional. Your air conditioner likely has a refrigerant leak, which can damage the system and impact your health. Refrigerant is a delicate substance, and you should never handle it on your own. Seek professional help when dealing with refrigerant issues.

If your AC system is making strange noises, don’t wait for the problem to go away on its own. Contact Bogdan Company today to have your air conditioner inspected by a trained, experienced and friendly HVAC professional.
