Do You Hear That? Yes, It’s Your AC


Your air conditioner can make some pretty scary noises. No, it’s not supposed to make scary noises, but it can and it will if it gets neglected or runs into a problem. In fact, noises can be the easiest way to tell that something is wrong and your first sign to call a professional for help. Before you start wondering whether or not your AC is making a good or bad sound, remember that any uncomfortable or loud noises are not good. Your AC is supposed to work in the background of your home, and if it’s in the foreground then something isn’t right.

That being said, we’re the HVAC company in Grand Rapids, MI that can help you get to the bottom of what noises your AC is making and why. If you need a helping hand, or want some more information as to the different noises your system can make, be sure to call us!

The Noises Your AC Might Make

Take a look below at some common noises an air conditioner might make when it runs into problems.

Rattling and Clanging

Rattling or clanging noises indicate that something is loose or a blower fan is misaligned. This might not seem like a catastrophic problem at first, but it can easily become a bad problem over time. Those loose parts or misaligned components will quickly start to bump into other components and compound into multiple problems that will increase the price of your repair bill. The earlier this is taken care of, the better.


Buzzing often indicates an electrical problem. When capacitors aren’t working, or a wire is frayed inside your system, it will likely make clicking or buzzing noises to indicate that the electrical input isn’t working properly. This can compound into other problems as your system could stop working abruptly, stressing or wearing down certain components.

Hissing and Bubbling

If you’ve ever wondered whether or not your air conditioner is leaking refrigerant, well this is the answer. Hissing or bubbling noises generally indicate that refrigerant is escaping from your system’s refrigerant line, or that oxygen has made its way into the refrigerant line. Either way, this isn’t good and it’s likely going to lead to additional problems if the leak isn’t patched and the refrigerant recharged. Call our team if you suspect that your system is leaking refrigerant and we’ll make sure you’re taken care of.

Shrieking or Grinding

This noise should never come from your air conditioner, and if it is, then you’re in need of some serious help. Shrieking or grinding can be the distinct sound of metal on metal, causing friction and heat which will ultimately lead to an early retirement for your system. Your air conditioner might need lubrication, a part replacement, or some extensive work, but you’ll only really know the true cost when you call to have a professional assess the situation.
