When the temperatures drop, your furnace becomes the heart of your home’s comfort. But waiting until it’s freezing to realize your system needs attention is never ideal. A little fall maintenance goes a long way in preventing breakdowns, lowering energy bills, and keeping your family warm.
Here are five simple, essential steps to get your furnace ready before winter hits.
Replace or Clean Your Furnace Filter
A clogged filter restricts airflow, makes your system work harder, and decreases efficiency.
- Change your furnace filter every 1–3 months depending on your household (pets, allergies, etc.).
- Use a pleated or high-MERV filter for better air quality.
Test Your Thermostat
Make sure your thermostat is working before cold weather arrives.
- Set it to “Heat” mode and raise the temperature a few degrees.
- Listen for the system to start up and check for warm air.
- If you have a smart thermostat, check for software updates.
Clear Vents and Registers
Blocked vents make your furnace work harder and heat unevenly.
- Walk through your home and make sure vents and registers are open and unobstructed.
- Vacuum dust and debris from grilles to improve airflow.
Check the Exhaust and Intake Pipes
Most high-efficiency furnaces have PVC venting pipes that lead outside.
- Make sure there are no blockages like leaves, snow, or nests.
- A blocked vent can cause safety issues like carbon monoxide buildup.
Schedule a Professional Furnace Tune-Up
Even if your furnace seems fine, a fall tune-up is essential.
- A licensed technician will clean internal components, inspect heat exchangers, check gas pressure, and ensure safe operation.
- Annual maintenance reduces breakdown risk and can even help maintain your warranty.
Bonus Tip: Check Your Carbon Monoxide Detector
Fall is the perfect time to test your CO detectors and replace the batteries. These alarms are critical for homes with gas furnaces.
