Your furnace keeps the house warm in the coldest months, which is also when the system tends to encounter issues and needs furnace repair. Below are some of the most common issues you may experience with your heating installation this season.

Common Furnace Problems

1. Slipping or Worn Belt

The blower belt is responsible for the fan running at optimum efficiency. If it becomes damaged and worn or slips, a professional should replace it so that you avoid high energy bills and insufficient heating. If the belt experiences any of these problems, it emits a loud squealing noise when the fan is on. How often you should replace the belt depends on the type of unit and how often you use it. In any case, have a reliable heating contractor inspect it yearly for signs of damage.

2. Clogged Filters

Clean or change your furnace filters every few months or at the frequency recommended in your user’s manual. Without regular maintenance, they can become clogged, leading to a number of issues. Your furnace may stop putting out hot air due to limited airflow, and sediment and grime can circulate throughout the system and reduce efficiency. It can also damage the limit switch sensors, which tell the fan when to turn on and off, requiring furnace repairs to fix.

3. Yellow or Extinguished Pilot Light

In a gas furnace, your pilot light provides the flame the system needs to ignite the fuel when it kicks on. If your pilot light is out, there’s no ignition, and your furnace doesn’t work. A pilot light that won’t stay lit could indicate a dirty or bent thermocouple, or a faulty gas supply or regulator. If your pilot light is yellow instead of blue or white, it indicates a high output of carbon monoxide, which can be hazardous to your health. In either case, a professional should check and replace the affected parts.
