1. Regularly Change or Clean Filters

The filter is one of the most crucial parts of your furnace, yet it’s often overlooked. A dirty filter can restrict airflow, making your furnace work harder than necessary.

Steps to Change/Clean Filters:

• Turn Off Your Furnace: Always turn off your furnace before accessing the filter.
• Locate the Filter: Most filters are located near the blower compartment.
• Remove the Old Filter: Slide it out carefully to avoid releasing dust and debris.
• Check the Filter: If it’s a disposable filter, replace it with a new one. If it’s a reusable filter, clean it according to the manufacturer’s instructions.
• Install the New or Cleaned Filter: Ensure it’s properly secured and facing the right direction.

Frequency:

• Disposable Filters: Every 1-3 months.
• Reusable Filters: Clean every 1-3 months and replace annually.

2. Inspect the Thermostat

Your thermostat controls your furnace, so keeping it in good working order is vital.

Steps to Inspect:

• Check the Settings: Ensure it’s set to “heat” and the temperature is set correctly.
• Clean the Thermostat: Gently clean the outside to remove any dust or debris.
• Test the Functionality: Set the thermostat a few degrees higher and listen for the furnace to start and run smoothly.

3. Clean the Furnace Area

Keeping the area around your furnace clean can prevent debris from clogging the system.

Steps to Clean:

• Turn Off the Furnace.
• Vacuum Around the Unit.
• Wipe Down Surfaces with a damp cloth to remove dust.

4. Check Vents and Registers

Blocked vents can restrict airflow and make your furnace work harder.

• Steps to Check:
