Football season in Pittsburgh means one thing: the weather is about to change. The same weeks that bring the first Steelers games also bring the first cool nights, the first mornings where you reach for a sweatshirt, and the first time you think about whether your furnace is ready. Here is what to check before you need it.

Replace the filter before the first cold snap

The air filter is the easiest maintenance item a homeowner can handle, and it is the one most often skipped. A clogged filter restricts airflow, makes the system work harder, and can cause the furnace to overheat and shut down on its safety switch. Replace it now, before you need heat, and you will start the season with a clean system.

Test the heat before you need it

Switch the thermostat to Heat and set it a few degrees above room temperature. The furnace should fire within a few minutes. If it does not, or if it makes unusual noises when it starts, you have time to schedule a service call before the cold arrives — rather than calling for emergency service on the first cold night of the year.

Check the carbon monoxide detectors

The start of heating season is a good time to test your CO detectors and replace batteries. Carbon monoxide is odorless and colorless — a working detector is your only warning. If any detector is more than 5–7 years old, replace it.
