Four Sounds You Don't Want To Hear From Your Air Conditioner

If your air conditioner system is working properly, you should barely even know that it exists. Outside of proper maintenance and the occasional repair job, an air conditioner's job is to operate silently in the background, providing cool air year-round.

If you start hearing sounds coming from your HVAC system, it might cause you to raise an eyebrow or two. Outside of the steady hum whenever it clicks on, you shouldn't really hear any sounds at all coming through your vents; if you do, there are a few specific noises to keep an ear out for. If you hear any of the below sounds, schedule an HVAC company to perform an air conditioning repair as soon as possible, before the problem gets worse.

Rattling

While the sound of the baby rattle might be pleasant, a rattling through your HVAC system could mean that a part is loose. Sometimes a loose bolt will fly off and rattle around inside the ductwork, while at other times, you could have an entire part that snapped loose inside of your air-conditioning unit. Either way, it's a good idea to have an HVAC company come out and perform an AC repair.

Squealing

There is very little inside your air conditioning unit that should cause a squealing sound, but one thing that definitely will is your fan motor. If the belt is old and the bearing has gone bad, it'll crack and make a squealing sound as it operates. You want to schedule an air conditioning repair to fix this because replacing the belt is a whole lot easier than replacing the entire blower. Not to mention, it's a lot less inconvenient.

Hissing

Whether it's loud or soft, a hissing sound is usually indicative of air that is leaving your house somewhere. The normal culprit is a duct that is broken or has sprung a leak, in which case, you'll need a professional to reseal it for you. Diagnosing an air leak is a difficult job in the first place, but patching it up is a whole other beast entirely.

Slapping

Though a slapping sound shouldn't indicate that your air conditioning unit is about to fail, it is incredibly annoying and could lead to rapid deterioration inside the unit. The usual culprit is a loose fan blade that is hitting the sides as it rotates, which requires a professional to perform air conditioning repair to get inside the unit and fix the problem.
