Do you hear banging, clicking, or other strange sounds every time your system kicks on? If your HVAC system has started making noises you’ve never heard before, you’re probably wondering if it’s something minor or the start of a much bigger problem.
These strange sounds are your system’s way of warning you that something is wrong, before it becomes something worse.
Here’s what to listen for.
Common Noises and What They Mean
If you hear any of these sounds, it’s an indication that your system might need maintenance or repair:
#1. Banging or Clanking
Usually points to a loose or broken part inside the blower assembly, like a connecting rod or piston pin; this can cause serious internal damage.
#2. Squealing or Screeching
Often a sign of a worn-out blower motor belt or a motor bearing that needs lubrication, this can be an easy fix if taken care of as soon as possible.
#3. Clicking
A repeated clicking that repeats and doesn’t just occur at startup could mean a failing relay or a thermostat issue causing the system to cycle on and off too often.
#4. Hissing
May indicate a refrigerant leak, which affects both cooling performance and efficiency.
#5. Rattling
Sometimes as simple as loose screws or panels, but can also mean debris caught in the ductwork or outdoor unit.
