What are the Most Common Furnace Problems and Repairs?

While daytime temperatures in Kyle, Texas, are still relatively warm, the nighttime lows have bordered on freezing at times. As a result, you’ve likely turned to your heating system to maintain a comfortable environment at home. Don’t let a faulty furnace stop that from happening. If you notice these furnace problems, schedule a repair right away:

No Heat in the Home

First, check your thermostat to ensure it’s set to “Heat” and that the temperature is low enough to make the heater turn on. If your furnace still fails to blow warm air into your home via the supply vents, you might have an electric ignition or a pilot control problem. In either case, you’ll need a professional service technician to take a closer look.

Loud Squeals or Scraping

It’s normal for your furnace to make noises while it turns on and off. But if you hear squeals or scraping, something is definitely wrong. Squeals indicate a slipped or frayed blower belt, while scraping signals worn ball bearings.

Yellow Pilot Light

If you have a gas furnace, you should check its pilot light periodically to make sure it’s lit properly. If it’s flickering or yellow, there’s likely excess carbon monoxide in your gas furnace. The pilot light should burn blue. If it doesn’t, turn off your furnace and contact an HVAC professional right away to prevent endangering you and your family.

Frequent Cycling

Frequent cycling wastes energy. There are numerous reasons your furnace might cycle on and off frequently, including a clogged air filter or a wrong thermostat setting. For optimal operation, you should change your furnace’s filter every 30 to 90 days. By doing so, you’ll not only help avoid straining the furnace but also prevent poor indoor air quality.
