A healthy, comfortable home during a Lake Zurich, IL, winter requires a sound, efficient heating system. The last thing you want to experience is a furnace repair when the temperatures plummet to single digits. To prevent this unpleasant occurrence, you should know the warning signs that signal your heater will soon need repair.


If your furnace is a “tweenager,” the chances are good that it will soon need repairs. Heaters have a typical lifespan of 15 to 20 years; when they approach the 10- to 12-year mark, components will start showing the effects of time and begin wearing out.

Frequent Cycling

Heaters that constantly turn on and off could be triggered by safety switches that monitor heat or gas buildup. A faulty blower motor, malfunctioning thermostat, and a dirty flame sensor are among the reasons for tripped switches.

Odd Noises

As humans age, our bones and joints begin to creak and groan. Heaters also start making strange noises as they near the end of their life cycle. Thumps, bangs, screeches, pops, and scrapes all indicate something is wrong, and a furnace repair is imminent.

Inconsistent Temperatures

Inconsistent heating throughout your home is a significant sign that your heater needs a repair. Inconsistent temperatures can stem from a bad thermostat, leaky ductwork, bad airflow, and an aging heater.

Yellow Burner Flame

Heaters should have a blue burner flame. A yellow flame could mean the presence of poisonous carbon monoxide. Other signs of carbon monoxide include water leaking from the vent or flue pipe, no upward draft in your chimney, excessive rust on flue pipes, and soot streaks.
