5 HVAC System Sounds You Don’t Want to Hear

April 20, 2019

When your HVAC is working, you may hear an occasional click when the system turns on or off. Any strange sounds means it’s time to call a professional repair company to your home. Here are five sounds that you don’t want to hear from your HVAC unit.

1. Rattling Noises

You should never ignore a rattling sound. In most cases, this means there’s a loose part or debris in the housing of the unit. You may also hear rattling from the ventilation system. When you turn to Cooper Heating & Cooling, we can clean and check your ductwork anywhere in the Denver area.

2. Squealing Sounds

If you hear this noise, it can be a sign of a loose belt. The squealing comes from lost lubrication in the fan’s housing unit. Belt replacements are an easy fix for a technician. When you hear a squealing sound, it’s important to schedule a service visit right away. If you wait, you can cause more damage to your HVAC system.

3. Buzzing

There are several different issues that can cause a buzzing sound from your HVAC unit. You might have excess dust in the vents. On the other hand, a part or component might be loose. If a component has lost lubrication, then you may hear a slight buzz as well. In any case, you want a trained technician to check out the source of this strange sound.

4. Excessive Clicking

You’ll hear an occasional click when your HVAC starts to operate. If you hear rapid clicking sounds, that’s not a good sign. These clicks indicate that something has failed in the electric panel. This sound needs to be inspected by one of our trained technicians.

5. Thumping

Thumping sounds are caused by an obstruction in the blower blade compartment. Blades are striking an obstruction and can break in the unit. A technician can inspect your HVAC system and remove any debris from the vents.
