Signs You Need Furnace Repair Service

If you notice any of the below signs, it's essential to contact a professional HVAC technician from the Harkey team to assess and address the issues promptly, preventing further damage and ensuring the longevity of your heating system. Regular maintenance can also help prevent many of these issues and keep your furnace running smoothly. If you notice any of the following issues, give the Harkey Heating Cooling & Plumbing team a call:

  • Insufficient Heating: If your furnace is struggling to maintain a comfortable temperature, it could indicate issues with the heating elements, thermostat, or other components.
  • Unusual Noises: Strange sounds such as banging, rattling, or whining may indicate mechanical problems, loose parts, or issues with the ignition system that require prompt attention.
  • Increased Energy Bills: A sudden spike in energy bills without a corresponding increase in usage could signal reduced efficiency in the furnace, prompting the need for repairs.
  • Frequent Cycling On and Off: If your furnace is cycling on and off more frequently than usual, it may be a sign of a malfunctioning thermostat, a clogged filter, or other issues affecting the system's operation.
  • Inconsistent Pilot Light: For gas furnaces, an inconsistent or yellow pilot light may indicate issues with the burner or the gas supply, requiring professional inspection and repair.


  • Poor Air Quality: Dust, soot, or an increase in indoor allergies could be indicators of a malfunctioning furnace that requires attention to maintain proper combustion and ventilation.
  • Visible Signs of Wear or Corrosion: Inspect the furnace for any visible signs of wear, corrosion, or rust on components. These issues could affect the furnace's performance and efficiency.
  • Strange Odors: Unusual smells, especially those of burning or gas odors, should not be ignored. They may indicate problems with the combustion process or gas leaks, necessitating immediate attention.
  • Age of the Furnace: If the furnace is approaching or exceeding its expected lifespan, it may be more prone to breakdowns. Regular maintenance and timely repairs become crucial for older units.
  • Thermostat Malfunctions: If the thermostat is not responding accurately to temperature adjustments, it could lead to uneven heating or cooling. This may require recalibration or replacement.
