Winters in Chicagoland rarely come in slowly. Without warning, temperatures will start to plummet, and families across the area will fire up their furnaces. Some of those furnaces will fail to turn on, leaving homeowners in a bind.

Furnace breakdowns and malfunctions are not usually loud or dramatic, but it is quickly apparent that something has gone wrong when your furnace won’t work.

If this is your situation, chances are one of two things is happening:

Sudden Heat Loss

The most common furnace breakdown scenario is when a furnace shuts off unexpectedly and will not turn on again. Predictably, this often happens at the worst time possible, so families wake up to find their homes freezing cold in the middle of the night.

There are a large variety of issues that could cause sudden heat loss in your home, such as a power outage, a malfunctioning pilot light, or faulty wiring in your furnace. Because there is no straightforward solution, it’s always best to call a trained professional that can assess your furnace and find a way to fix it.

Short Cycling

While this furnace issue is less common, it’s no less of a complication. Short cycling is when your furnace clicks on and off in short bursts instead of running in a sustained duration. When your furnace has these operates for these short bursts, your home fails to warm like it normally would. The start-stop nature of its operation also adds a lot of wear-and-tear to your unit.

The most likely cause of this problem is a dirty filter. A clogged furnace filter restricts its airflow and creates a backup of air and heat. When this occurs, the furnace’s internal temperature spikes too high, which causes the safety switch to power the unit down.

After shutting down, your furnace powers back up in an attempt to heat your home, and the cycle begins anew.
