Furnace Maintenance

To verify proper operation
Every 1-3 months
  • Replace air filter regularly based on manufacturer’s recommendation.
  • If you ever smell natural gas, leave your home immediately. Call your natural gas provider after you’ve left your home.
  • Turn on system only when outside air temperature is below 65 degrees Fahrenheit.
  • Set thermostat at desired temperature. If the system does not operate, check to see that thermostat is set to “HEAT” setting. Also check that fan panel on furnace unit is secure.
    • There is a switch behind the panel that will keep the furnace from operating if the panel is loose.
    • If that doesn’t work, check the circuit breakers. Verify that breakers are in the “ON” position. If any breakers relating to the fan or compressor are tripped, switch them to the “OFF” position then to the “ON” position.
    • Otherwise, consult with a qualified HVAC contractor for assistance as necessary.
  • If the system is operating properly, confirm that noticeably warm air is blowing out of the air vents. A mild odor is common the first time you turn on the heat and should dissipate shortly.
  • Check that any auxiliary heaters are operational (heat pump).
  • Occasionally, heat pumps will activate a defrost cycle which will melt ice buildup on the internal coils of the outside unit. When this occurs, steam will be seen rising from the unit. This is normal and not cause for concern, but use your best judgment if things don’t seem right.
  • Make sure the fresh air duct near a natural gas unit is open and unobstructed.
  • Consider installing ceiling fans where desirable. They help with air circulation and enable the system to operate more efficiently.
  • Allow sunlight to enter your home during the warmest parts of the day.
  • Make sure all heating and return air vents are clean, clear, and unobstructed.
  • Set air vent vanes downward on lower floors and slightly upward on upper floors.
