Don’t Cover Your Ears; These AC Noises Shouldn’t be Ignored!

woman-looking-surprisedThe Comfort Bear is here again with some more great tips for you.

Today, we’re talking about hearing. No, that’s not a typo–think about the things you hear in your home every day. There are some noises that are so familiar that you might not even really notice them–like the sound of your fridge running, your ice-maker working, a toilet flushing, etc.

You may also hear the hum of your AC fans and a slight clicking after it stops cycling. But what if your air conditioner is making a noise you don’t recognize? If it’s quiet enough, couldn’t you just ignore it? Well, the Comfort Bear probably doesn’t have to tell you this, but even the smallest problem now can turn into a huge emergency later.

So, what should you listen for?

Shrieking/Screeching

Do you hear a loud, mechanical noise coming from your air conditioner that you’ve never heard before? This is most likely a sign of a motor problem, or at least the sign of a motor bearing that’s worn-down (which is not inherently uncommon or bad, but should be repaired as soon as possible).

A worn-down bearing will eventually cause too much friction on the motor, and could permanently damage it. Our professionals will quickly and accurately replace these bearings in order to save your motor and prevent more damage later on down the road.

Grinding

This is another indication of a possible motor problem. The most common cause of this sound is a motor that’s accumulated too much dust and debris, or has lost too much lubrication over time. Again, this is a normal part of AC wear and tear (and something we check for during maintenance). However, it should never be ignored.

Additionally, if the noise is accompanied by an acrid smell coming from the vents, it’s an almost definite sign that your motor is already overheating. Be sure to turn off your air conditioner right away, and give our professionals a call.

Rattling

This may seem like a minor problem, and in some cases it can be. Take, for instance, a loose cabinet door. You can resolve this by yourself, with nothing more than a few twists of a screwdriver.

It could also, however, be the sign of something more serious. You could have loose AC components being knocked around in your blower fan, or bent fan blades. It might even be that your AC system’s cabinet is coming loose from the foundation, or you could have damage to your ducts. If you’re ever in doubt about what a certain sound means for your air conditioner, the best thing you can do is call in a pro.

Hissing/Bubbling

Both of these sounds indicate a detrimental problem for your air conditioner—a refrigerant leak. Refrigerant is not meant to leave your air conditioning system, despite the common misconception that air conditioners consume refrigerant. Alas, it is not a fuel—it is regularly recycled throughout the air conditioner’s lifespan. Well, ideally it is, anyway.

If your system is losing refrigerant, it means there is a leak that must be accurately located and repaired. Without repairs, you could find yourself facing a completely broken down air conditioner in a matter of months or sooner.
