Types of Furnace Noises
There are several reasons why you may have a loud furnace. Some of the primary types of furnaces noises include:
- Loud banging
It is important to remember that all furnaces will make some type of noise, particularly when they first start. The most common start-up noises are clicking or popping. After turning on, a furnace (specifically, an older unit) might make a humming sound.
If noises persist or become louder, there could be underlying problems. Here are some of the top causes of furnace noises:
- Loose blower wheel
- Furnace blower motor issues
- Broken belt
- Clogged air filter
- Loose panels or parts
- Problems with ignition

Regularly replacing your air filter and checking around the furnace to keep it clean is critical. Regular furnace maintenance in Denver, CO, can improve energy efficiency and safety. If you start hearing loud rattling, you could also check for any obvious loose parts that need simple tightening.
What Is a Furnace Blower Motor Noise?
How can you tell when your furnace blower is making noise? Some of the most common noises associated with your furnace blower motor are:
There are many components that could be affecting the furnace blower motor, from loose parts to debris caught between the blades. Without prompt maintenance, repairs, or checks, you could wear out your motor and accrue costly repairs. Properly caring for your furnace blower motor can prolong your furnace’s lifespan, which typically lasts between 15 and 30 years.
The blower includes the motor, fans, and electrical system. While any one of these parts may need repairing, newer furnaces should have auto shut-off functions if electrical problems arise, like overheating.
If you start noticing your furnace turning off and on repeatedly, you could have issues with the motor, and the electrical system is overriding it for safety concerns. Other than noises, poor air flow from vents is another indicator of problems with the furnace blower motor.
