Scorching highs and frigid lows make having a functioning HVAC system a must in the Las Vegas, Nevada, area. That’s why you need to pay close attention to the sounds your HVAC system is making. New and unusual sounds are signs of trouble. Keep an ear out for new HVAC system sounds so that you can take prompt action and avoid facing the heat or dealing with an expensive breakdown.

Thumping or Banging

Thumping or banging could mean that there’s an issue with the blower or motor. Typically, the sound you’re hearing is a component that has come loose and is rattling around inside the unit. This could be the motor mount, motor bearings, or some other part, and it is best to turn off the unit to prevent further damage.

Screeching or Squealing

These HVAC system sounds typically indicate a problem with the compressor belt or the motor bearing. If you hear screeching or squealing, it could be due to the pistons of the compressor wearing down—which is a tell-tale sign that it’s time to replace these parts. If you ignore these noises, your blower could stop functioning completely.

Humming or Buzzing

It’s normal for your HVAC unit to make a little humming noise when it’s starting up. However, if you still hear this sound as the unit continues to operate, it could be a sign of a problem with the compressor or isolation feet (small pieces of rubber upon which the compressor sits). In some cases, the inside of the unit might even be freezing up.

Clicking

You might hear a soft click when your HVAC unit turns on or off. However, if you still hear a clicking sound while the unit is operating, it could be a problem with the control panel, outside compressor, or the interior electrical controls.
