When you switch from AC to heat in the fall, there are a few crucial steps: start by changing a dirty filter, testing the thermostat, checking airflow at the vents, and running the furnace before you need it every day. These simple tasks can catch common problems early and help your heating system start the season with less strain.
Here’s what to check in detail as cooling season winds down and colder weather moves into Champaign.
Start With a Fresh Filter and Clear Vents
A clean filter is one of the easiest ways to help your furnace move air properly. If the filter is packed with dust after a summer of heavy AC use, replacing it before heating season can reduce airflow problems and keep the blower from working harder than necessary.
Check supply and return vents at the same time. Make sure furniture, rugs, or other items haven’t blocked them during the summer. Closing vents in unused rooms can also create pressure problems, so leave them open unless your system was specifically designed for zoning.
Test the Heat While the Weather Is Still Mild
Turn the thermostat to heating mode and let the furnace or heat pump complete a few normal cycles. You should feel steady warm air, and the system should shut off once the house reaches the temperature you set.
A brief dusty smell at first startup can be normal after the furnace has been sitting unused. Persistent burning smells, repeated cycling, unusual noises, or weak heat are different. Those signs may call for furnace repair before colder weather arrives.
If you have a heat pump, always test the transfer switch before you really need to use heating mode. That gives you time to schedule heat pump repair if the switch doesn’t work.
Check Your Thermostat Settings for Fall
Review your thermostat schedule instead of carrying summer settings into heating season. Lowering the temperature while you’re asleep or away can reduce heating use, but large temperature swings aren’t always necessary. A steady schedule that fits when you’re actually home is usually easier on both comfort and energy use.
If the thermostat doesn’t respond correctly when you switch modes, don’t assume the furnace or heat pump is the problem. Testing it now gives you time to sort out a control issue before the system is running every day.
Finish the Seasonal Changeover With a Tune-Up
Homeowner checks are a good first step, but they can’t show you what is happening inside the furnace. Professional furnace maintenance can catch wear, dirty components, safety issues, and airflow problems before they lead to a breakdown. We also offer a maintenance agreement that includes a fall heating check and a spring AC check.
