Common Late-Heating Season Furnace Repairs


As we get deeper into the heating season, you begin to appreciate what a workhorse your furnace is, tirelessly keeping your home warm and cozy. However, after months of continuous use, they may start exhibiting signs of wear and tear.

Addressing these issues promptly is crucial to ensure uninterrupted comfort and prevent more significant problems down the line. In this blog post, we’ll explore some common late-season heating issues homeowners may encounter that warrant a call for furnace repair in Fresno, CA, along with tips on troubleshooting and preventive maintenance. 

Common Late-Season Heating Issues

  • Dirty or Clogged Filters: Dirty filters restrict airflow, leading to reduced efficiency and potential damage to the furnace components. Regular filter replacement or cleaning is essential to ensure proper airflow and heating performance.
  • Faulty Thermostat: A malfunctioning thermostat can result in inaccurate temperature readings or failure to communicate with the furnace. Calibration or replacement may be necessary to restore proper functionality.
  • Worn-Out or Faulty Blower Motor: A malfunctioning blower motor can result in weak airflow or unusual noises. Depending on the severity of the issue, repair or replacement may be required to restore proper airflow and heating efficiency.
  • Ductwork Issues: Leaks, blockages, or damage in the ductwork can hinder airflow and reduce heating efficiency. Regular inspection and maintenance are essential to ensure the integrity of the ductwork and prevent potential problems.

Signs of Furnace Trouble

  • Uneven Heating: Despite setting the thermostat, you may notice cold spots in certain rooms, indicating potential airflow issues or thermostat malfunctions.
  • Strange Noises: Rattling, banging, or squealing noises emitting from the furnace can be alarming. These sounds often indicate loose or worn-out components that require attention.
  • Increased Energy Bills: If you notice unexpected spikes in your heating bills, it could be a sign of reduced furnace efficiency due to underlying issues.
  • Frequent Cycling: A furnace that turns on and off more frequently than usual may be struggling to maintain the desired temperature, signaling potential problems with the thermostat or airflow.
  • Weak Airflow: Reduced airflow from vents could be caused by clogged filters, ductwork issues, or a malfunctioning blower motor.
  • Pilot Light Issues: Difficulty in keeping the pilot light lit or changes in its flame color may indicate problems with ignition or gas supply.

Preventive Measures and Maintenance Tips

  • Regular Filter Replacement: Replace furnace filters every 1-3 months to ensure proper airflow and heating efficiency.
  • Professional Inspection: Schedule annual furnace tune-ups with our team to identify and address potential issues before they escalate.
  • Keeping Surroundings Clear: Ensure proper airflow around the furnace by keeping surrounding areas free from clutter or obstructions.
