Preparing Your Furnace for Winter: Essential Checks for Homeowners
Updated: 5 days ago
Why Fall is When Furnace Problems Show Up
A furnace that has sat unused since March doesn't fail gracefully. It typically fails on the first cold night when you actually need it. Dust that has settled in the system over summer, a pilot light that has gone out, or a crack that developed during the off-season all tend to surface the moment the system kicks back on.
What a Home Inspector Checks on a Furnace
During an inspection, we pay close attention to several key aspects of your furnace:
Age and Condition of the Unit: Most furnaces last 15–20 years.
Visible Rust, Corrosion, or Soot: We check around the burner and vents for any signs of wear.
Flue/Exhaust Venting: Proper venting is crucial for safety and efficiency.
Condition of the Air Filter: A clean filter is essential for optimal performance.
Signs of a Cracked Heat Exchanger: This is a critical safety concern.
Thermostat Communication: We ensure the thermostat and system are communicating correctly.
The One Defect That Matters Most: A Cracked Heat Exchanger
A cracked heat exchanger can allow carbon monoxide to leak into a home's air supply. This is one of the more serious issues we look for during a fall inspection. It's rarely visible without opening up the unit and does not announce itself like a strange noise might.
Simple Things Homeowners Can Check Before Calling Anyone
Before calling for professional help, homeowners can perform a few simple checks:
Replace the Air Filter: A clogged filter is behind many "no heat" calls.
Test the Thermostat Batteries: Ensure your thermostat is functioning properly.
Clear Surroundings: Remove anything stacked around the furnace or vents.
Listen for Unusual Noises: Pay attention for banging, rattling, or a burning smell when you first turn it on this fall.
Gas Smell: If you ever smell gas, leave the house immediately and call your gas provider. Don't wait for an inspection in that case.
