\"old-ac-unit\"You\u2019re having a cookout in your backyard and suddenly your AC unit begins making a horrible grinding noise. All eyes inevitably turn toward you wanting to know what that\u2019s all about. Or maybe you have guests over for dinner, and horror movie-style squealing and shrieking begins coming out of the AC vents throughout your house. Once again, everyone will look to you as if to ask, \u201cHow could you let this happen?\u201d Don\u2019t worry: There are a variety of causes (and cures!) for these noises coming from your AC which we\u2019ll cover below.<\/p>\n

Sources of the Sound Coming from Your AC<\/h2>\n

No matter the source of the sound coming from your AC, the problem won\u2019t go away on its own. Sure, you may breathe a sigh of relief when an intermittent noise disappears for the moment, but this typically indicates a more serious issue. Talk to your local AC experts<\/a> to determine the cause of the problem as well as the best way to address it.<\/p>\n

1. Thumping and Banging<\/h3>\n

Sounds like this coming from your exterior AC unit can be a clear sign of trouble with the compressor such as a broken connecting rod or crankshaft. You\u2019ll need to cut off the system immediately and call for expert help. If you need to replace the compressor, that\u2019ll likely cost at least $1,500. Then again, if it\u2019s a loose fan blade \u2013 which can sound equally bad \u2013 you may have a significantly lower repair bill.<\/p>\n

2. Buzzing and Rattling<\/h3>\n

The sources of these noises vary widely: an air filter which needs replacing, dirty cooling coils, or just loose parts which need tightening. No matter what, it\u2019ll be difficult for the average homeowner to determine the exact cause of these sounds or exactly how to deal with them.<\/p>\n

3. Hissing and Whistling<\/h3>\n

Best case scenario, the source of these sounds will be leaking ductwork. While you don\u2019t want to fix these leaks on your own, a professional will have the right supplies to deal with them. Then again, this could be a sign refrigerant is leaking out of your system, and in that case, you need to call for help right away.<\/p>\n

4. Screeching and Squealing<\/h3>\n

These noises make it sound like you\u2019re in the middle of a scary movie as they travel through and are amplified by ductwork. They\u2019re usually caused by belts in the interior unit wearing out or being loose. You might also have a fan out of balance.<\/p>\n

5. Clanging and Grinding<\/h3>\n

These sounds usually indicate a problem with your fans: either their motors are going out or there is a problem with the ball bearings. You\u2019ll need a professional assessment to determine the best course of action.<\/p>\n
