Physical Symptoms and Noises:

  • Unusual noises such as banging, rattling, or loud sounds from the blower.
  • Reduced airflow through the vents or uneven temperatures across different rooms.
  • A pilot light flame that appears yellow, which indicates incomplete combustion.
  • Short cycling, where the furnace turns on and off too frequently.

Operational Issues:

  • Thermostat malfunctions resulting in inconsistent heating.
  • A sudden increase in energy bills, often indicating the system is operating up to 15 percent less efficiently.
  • Constant dust buildup from area pollen affecting the blower motor.

Safety Warning Signs:
