These days, home air conditioning units are relatively quiet, so when they start making noises, it’s something to be concerned about. Upon the first sign of an unusual sound, you should call a professional and schedule air conditioning service in St. Louis, MO right away. Catching these issues quickly will increase your chances of having your AC unit repaired rather than needing to have it completely replaced, ultimately saving you a ton of money. Here are the most common noises you should not ignore.
A Hammering Noise
When your AC unit starts making a hammering noise, it can mean there’s a loose or broken component floating around the system. If addressed quickly, this part can be replaced or fixed without a problem. However, the longer it is ignored, the more damage it will do to the system’s interior and the more costly it will be for you to fix.
A Squeaking Sound
Your AC system’s fans and indoor blower can sometimes give off a squeaking sound that can be heard through the duct system. This will often mean that the fan or blower is on its way out and will need to be replaced. The noise is heard most often when the system first starts up, but can occur at any time.
A Rattle or Vibration
When you begin to hear a rattling sound coming from your AC unit, you’ll want to first check that outdoor debris such as leaves or branches hasn’t clogged the system. If cleaning up the debris doesn’t fix the noise, check that the unit’s casing screws aren’t loose and creating the vibrating sound. Other causes can be a loose fan or other parts that require tightening and will require an expert to repair.
A High-Pitched Hiss
When you hear a high-pitched hiss or whistle, the cause is likely a refrigerant leak. The hissing sound is caused by the buildup of internal pressure, which can be extremely dangerous. If you think your AC unit is making this sound, it’s important to turn it off right away. Some systems will have a safety feature that turns off your system automatically, and it should be left off if this occurs. Contact an HVAC expert right away so they can examine your system and perform the proper repairs.
A Buzzing Noise
If your AC unit begins making a buzzing noise, there are several potential causes. Your system might be clogged with outside debris, parts might be loose, parts may be grinding against each other or there’s a refrigerant leak. Most importantly, this sound is an indication that your AC unit is in desperate need of some professional attention.
