Why Is My Air Conditioner Making a Loud Noise?
Sure, it’s normal for your air conditioner to make enough noise for you to notice that it’s running. However, there may be cause for concern if that noise can be classified as loud or even disruptive. You might be panicking—”Do I need to replace my AC?” It all depends on what kind of noises you’re hearing. Below we’ve listed the most common noises homeowners hear and the causes behind each.
If you’re concerned about how much noise your AC is making, call Metro Heating & Cooling at (314) 845-5900 to talk to an AC specialist now!
Why Is My Air Conditioner Buzzing Loudly?
If your system is older, you might notice a buzzing sound that is most likely connected to an electrical issue. The source could be a faulty relay switch or condenser fan motor, an issue with your circuit breakers or electrical connections, or even a frozen AC unit. The unit will probably need to be repaired.

Why Is My Air Conditioner Squealing/Screeching?
A failing belt will certainly cause a squeal or screech to come from your blower motor. Replacing the belt before it breaks is fairly inexpensive, but your blower will no longer turn if the belt does break. There is also a chance that your motor simply needs lubricant. An expert will be able to tell you which of these is causing the problem.

Why Is My Air Conditioner Rattling, Thumping, Banging & Clanking?
Rattling and clanking are indications that you have a loose part in your AC system. Having this repaired before it completely detaches is important, because a loose part can cause significant damage to other areas of your unit. Loud banging or thumping may mean that the part has already broken off and is being thrown around your system.
There are some instances in which a rattling noise means that your air conditioner’s motor mounts have become loose or that the blower has become misaligned. You’ll need an HVAC technician to solve any of these issues.
We can fix that annoying AC clanking. Call (314) 845-5900 or contact Metro Heating & Cooling online today!
Why Is My AC Unit Making a Loud Whacking or Thwapping Noise?
Remember the sound a playing card would make when you attached it to your bicycle spokes? While it may have been a fun noise as a kid, as an adult homeowner, it’s not something you want to hear from your AC unit. While not critical, it can mean that some kind of debris has gotten caught in your blower blades. You’ll want to clean it out to avoid wearing down your motor.

Wait! What If My AC Makes a Loud Rattling or Screaming Noise from the Outside Unit?
A rattling sound coming from your outside compressor is a sign of loose hardware or a failing motor. While a squeal when your unit kicks on is normal, if the noise sounds more like a scream (and it doesn’t stop), your compressor is likely failing.
