If your gas furnace is not blowing warm air or is making strange noises, it’s time to check for obstructions in the blower motor or ductwork. Here’s a simple guide to help you clear them out and get your furnace running smoothly again.

Blow Away the Blower Motor

The blower motor is responsible for circulating warm air throughout your home. If it’s blocked, it can prevent the furnace from heating your space effectively. To check for obstructions, first turn off the power to the furnace at the circuit breaker or fuse box.

Next, locate the blower motor. It’s usually in the combustion chamber or near the furnace’s filter. Use a flashlight to inspect the motor and remove any visible debris like dust, lint, or pet hair. A soft brush or vacuum cleaner can help you reach into tight spots and remove smaller particles.

Declutter the Ductwork

The ductwork is the network of tubes that distributes warm air from the furnace to your rooms. If the ducts are clogged or blocked, it can restrict airflow and reduce the furnace’s efficiency.

To inspect the ductwork, follow the ducts from the furnace to the vents in your rooms. Look for any visible obstructions, such as dust bunnies, pet toys, or even dead mice. If you find anything blocking the ducts, carefully remove it.

If you have access to the ductwork’s access panels, open them up and check inside. You may find more obstructions or dirt that needs to be cleaned out. Use a vacuum cleaner with a soft brush attachment to remove any debris.

That’s a Wrap!

Once you’ve cleared any obstructions from the blower motor and ductwork, turn the power back on and restart the furnace. If the problem persists, there may be other issues that require professional attention. But don’t worry, you’ve already taken care of the most common causes of airflow problems.

Remember, regular maintenance is key to keeping your gas furnace operating at its best. Schedule an annual checkup with a qualified technician to ensure your furnace stays clean, efficient, and safe for years to come.
