Happy Fall! This season brings a welcome relief from summer humidity, but it also signals that cold, crisp Midwest winter nights are just around the corner. Before you switch your thermostat from cool to heat, taking time for routine maintenance ensures your heating system runs efficiently, safely, and without unexpected breakdowns when the first freeze hits. Here is your essential fall HVAC checklist to prep your system for the colder months ahead:
1. Swap Out Your Furnace Filter
-
Why it matters: A dirty filter restricts airflow, forcing your furnace to work harder, raise energy bills, and potentially overheat.
-
Action: Inspect your filter monthly and replace it every 1–3 months, especially if you have pets or active home renovations.
2. Test Your Thermostat Early
-
Why it matters: Catching calibration issues or a failing thermostat now beats discovering your heat doesn’t work on a sub-zero night.
-
Action: Switch your thermostat from “Cool” to “Heat” and set the temperature 3 to 5 degrees above the current room temperature. Listen for the furnace to kick on and verify warm air flows within a few minutes.
3. Clear Vents and Return Grilles
-
Why it matters: Blocked registers disrupt airflow balance, causing uneven heating and extra strain on your system.
-
Action: Walk through your home to ensure rug, curtain, or furniture placement isn’t blocking supply vents or return air grilles.
4. Clear the Outdoor AC Unit
-
Why it matters: Leaves, twigs, and summer debris trap moisture against your outdoor unit, encouraging rust and damage.
-
Action: Clear fallen leaves and brush away from the base of your outdoor unit. Give it a gentle rinse with a hose and let it dry completely before shutting it down for the season.
5. Test Smoke and Carbon Monoxide Detectors
-
-
Why it matters: Gas furnaces and heat sources pose a potential carbon monoxide risk if venting fails or heat exchangers crack.
-
your seasonal tune-up before the winter rush begins!
-
Action: Replace detector batteries every fall and press the test buttons on every level of your home, especially near sleeping areas.
-
6. Schedule Professional Annual Heating Maintenance
-
-
-
Why it matters: While home checks are critical, a trained technician checks electrical connections, inspects the heat exchanger for hazardous cracks, cleans burners, and verifies safe venting.
