Some Common Repairs Your Furnace May Require

Furnaces are one of the most commonly-used home heating systems, and with an average lifespan of 15-20 years, it is likely you will need to schedule your furnace for repair at least once during its lifetime. There are some furnace repairs our technicians see more than others when it comes to furnace repairs, and we’ll outline some of them below. But no matter what your particular heating repair issue in Elk Grove Village might be, the trained and certified technicians at Service King can help you.

Common Furnace Repairs

Here are some of the more common furnace repairs we see at Service King:

Problems with the Blower

The blower in your furnace pushes the hot air generated by the heat exchanger into your home. The blower has a motor, a fan belt, ball bearings and other small components that can develop problems that will affect the blower’s operation. Some typical issues that can develop with your blower are issues with frayed or corroded wiring, dried out ball bearings, worn or broken belts and loose or broken fan blades. Anything problems that affect the fan’s ability to move the air in your system correctly can create issues with air flow in your system.

Ignition Issues

There are 3 ways your furnace can ignite:

  • Standing pilot
  • Intermittent pilot
  • Hot surface ignition

Standing pilots are pilot lights that are on constantly; intermittent pilot and hot surface ignition are both types of electronic ignition and are only on when igniting the system. Today’s furnaces are no longer manufactured with standing pilots as electronic ignition is more energy efficient, but there are many furnaces that have standing pilot lights. Some of the common problems that can develop with ignition are problems with the thermocouple (standing pilot lights), lack of electronic spark (intermittent pilot) or a cracked probe (hot surface ignition). Each type of igniter can develop its own set of problems, but the results from each can be no heat. If your furnace is having problems igniting, call for a technician.

Low Air Flow

As mentioned above, low air flow can be caused by problems with your blower, but a secondary cause of low air flow is a dirty filter. Your furnace’s air filter should be changed every 3 months to remain effective and not become clogged. A clogged air filter can seriously restrict your system’s air flow, resulting in less air being delivered to your home and more stress on your heating system.
