As the seasons transition to the colder months, people switch to using the furnace to keep warm. As you do, it's a good idea to know how your furnace works, when is the best time to start using it, as well as some common signs that you may need a furnace repair. Here's what you need to know.

How Your Furnace Works

A furnace has three main components: a burner, a heat exchanger, and a blower motor. The burner heats air, which then passes through the heat exchanger, transferring its energy into the air that's pushed out by the blower motor. This air is circulated through your home via air ducts. The result is a warmer winter in your home.

After being dormant all summer long, it's important for a professional to check each of these components for any blocked passages or corrosion before you turn on your furnace.

Turning It On for the Season

Once a technician has checked all of your parts for any blockages or corrosion, you can turn your furnace on for the season. It's generally advised to do this around mid-October when temperatures start to drop, though many people try to wait till November. During this time, you should also change or clean the air filters so that they are fresh for the new season. All of this can help you avoid needing furnace repair.

When using your furnace for the first time after being off all summer, keep an eye out for any signs of malfunction or failure. Common signs might include loud noises from the motor, strange odors coming from vents, weak airflow, a pilot light that won't stay lit, or yellow flames instead of blue ones. If you notice any of these signs, it's best to contact a professional technician who can inspect and service your furnace.
