Don’t Get Spooked by Strange HVAC Noises This Halloween: Austin’s Guide to a Fright-Free, Cozy Home

As October rolls in, Austin finally starts to cool down. The evenings are crisp, the pumpkins are glowing, and maybe… your HVAC system is making unsettling noises. Before you assume your house is haunted, take a closer listen. Those spooky sounds might just be your system calling for help.

Here’s what those eerie noises could mean:

Banging or Clanking: Loose parts, a failing blower motor, or something trapped in the fan can all cause these rattling chains of sound.

Whistling: A ghostly whistle often means air is escaping through leaky ducts or a clogged filter is restricting airflow.

Squealing or Screeching: This spine-chilling sound is usually a worn belt or motor bearing — a quick fix before it turns into a full-blown nightmare.

Rattling: Sometimes it’s just loose screws or panels, but persistent rattling could point to ductwork issues.
