What Are Some Common Signs It's Time to Repair a Furnace?

Recognizing when your furnace may need repair is key to avoiding a complete breakdown. Here are some common signs that your furnace could be in need of a service or repair:

  • Unusual Noises: Banging, whistling, or groaning sounds from your furnace can indicate mechanical problems, airflow blockages, or issues with the blower motor.
  • Inconsistent Heating: If some rooms are too cold while others are too hot, or if the furnace struggles to maintain the set temperature, there could be an issue with the furnace itself or the thermostat.

  • Increased Heating Bills: An unexpected rise in heating costs can signal that your furnace is no longer operating efficiently and may need repairs.
  • Frequent Cycling: If the furnace turns on and off more frequently than it should, this could be a sign of a faulty thermostat, improper air circulation, or a clogged filter.
  • Yellow Pilot Light: For gas furnaces, a pilot light that is yellow instead of blue can indicate the presence of carbon monoxide, which is a serious issue that should be addressed immediately.
  • Difficulty Starting the Unit: If the furnace struggles to start up or doesn't start at all, there could be a problem with the ignition system or the pilot light.
  • Poor Air Quality: An increase in dust, dirt, or even signs of rust in the air or around the vent registers can suggest that the furnace filters need replacement or that the furnace itself requires maintenance.
  • Age of the Furnace: Furnaces typically last between 15-20 years. If your furnace is old and experiencing issues, it might be time for repairs or possibly a replacement.
  • Carbon Monoxide Detector Activation: If your carbon monoxide detector goes off, it's a clear sign that your furnace could be leaking this dangerous gas and needs to be serviced immediately.

If you notice any of these warning signs, it’s advisable to contact a professional HVAC technician to inspect your furnace and carry out any necessary repairs.

Common Furnace Repair Questions

Common furnace problems include a malfunctioning thermostat, issues with the pilot light or ignition system, worn-out bearings or belts, dirty filters leading to poor airflow, and cracks in the heat exchanger that can lead to carbon monoxide leaks.

It’s recommended to service your furnace annually to ensure it’s running safely and efficiently. Ideally, this should be done in early fall before the heating season begins.

The cost for a furnace tune-up varies by region and service provider but typically ranges from $80 to $200. This service usually includes inspecting and cleaning the furnace, checking for leaks and wear, testing its efficiency, and ensuring that it’s in good working order for the season ahead.

A furnace problem is considered an emergency if it poses a safety risk or significantly affects your comfort during extreme weather. Indicators of an emergency include strange smells like burning or gas, which could signal a fire hazard or gas leak; any signs of carbon monoxide presence, such as a headache, dizziness, or a CO detector alarm; unusual loud noises that could precede a breakdown; or complete loss of heating when the outdoor temperature is very low. If you encounter any of these issues, turn off your furnace and contact a professional immediately.

Delaying furnace repairs can lead to more serious and costly issues down the line. Small problems can quickly escalate into major malfunctions, potentially requiring a full system replacement. There’s also the risk of increased energy bills due to decreased efficiency, and most critically, there’s a safety risk — a malfunctioning furnace can lead to dangerous situations like gas leaks or carbon monoxide poisoning. It’s always best to address furnace repairs as soon as issues are noticed to ensure safety and optimal operation.
