Spooky Sounds Coming From Your HVAC Unit

Halloween is almost here, and your HVAC system might be making some spooky sounds as you turn on the furnace for the cold weather. There are some sounds that are perfectly normal, but other noises can signal that your HVAC unit is ready for a checkup and possibly some repairs. Here are three sounds that you should have an HVAC repair professional check out.

Banging or Clanking

If you hear a banging or clanking sound, you might imagine ghouls in the attic or basement clanking chains, but it's probably just a loose part on your HVAC system. An HVAC professional can pinpoint where the sound is coming from and replace the part that has broken off or needs to be tightened.

Squealing

If you wake up in the middle of the night to the sound of squealing you might feel a little on edge. Is it a poltergeist trying to make contact with you through your home's appliances? More than likely, it's not. Squealing sounds often indicate that there's an issue with the fan or motor in your furnace.

Screaming

A screaming sound doesn't mean that a banshee has taken residence in your garage. It usually means that there's a coolant leak with your air conditioner. You want to address this as soon as you hear it because, if the problem isn't corrected, this can turn into thousands of dollars in repairs. If you hear this sound, shut off your system immediately and call a professional HVAC repairman.

There are a lot of spooky sounds that you hear around Halloween, but not all of them mean that your house is haunted. If you notice any of the sound effects listed above, it might be time to call in the professionals to have your HVAC unit looked at.
