How to Fix Your Furnace Filter Systems for Efficient and Safe Operation

The primary function of a furnace filter is to remove dust, dirt, and debris from the air entering your home. However, if these filters become clogged or damaged, it can lead to inefficient combustion, reduced airflow, and even safety hazards. In this article, we will explore how to fix common issues with your furnace filter systems.

Signs of a Clogged Furnace Filter

Identify the following signs to determine if your furnace filter needs attention:

• A decrease in air flow or heating output
• Coughing, choking, or difficulty breathing
• Frequent start-up and shut-down of the furnace
• Unpleasant odors from the furnace

Fixing a Clogged Furnace Filter

If your furnace filter is clogged, try these simple steps to clean it:

1. Turn off the power to the furnace at the circuit breaker or fuse box.
2. Remove the air filter cover and gently brush away any debris from the filter.
3. Use a vacuum cleaner with a soft brush attachment to remove any remaining dust and dirt from the filter.
4. Reassemble the air filter cover and replace it if necessary.

Replacing a Clogged Furnace Filter
