 Furnace Maintenance:

If your system isn’t operating as it should, you should call us as soon as possible. Diagnosing a problem early often makes it easier and more affordable to repair.  One of the best ways to prevent heating repairs is to schedule regular maintenance. Plan to have your heating system serviced once a year. Schedule this appointment in early fall, before you turn your system on for the first time after the cooling season.


How A Gas Furnace Works To Heat Your Home:


Thermostat Activation:

  • When your home's interior cools, the thermostat signals the furnace to start its heating process.

Safety Checks Initiation:

  • The furnace control board takes charge, conducting a thorough safety check.
  • The draft inducer motor starts spinning at up to 3500 rpm, creating a vacuum that closes the vacuum pressure switch.

Ignition Process:

  • The igniter begins to glow, and the gas valve, powered by the furnace control board, opens to release gas.
  • The gas combines with the glowing igniter, creating a flame.

Flame Verification:

  • The flame interacts with the flame sensor rod, signaling that a sustained and hot flame is present
  • Blower Activation:
  • Within 30 to 60 seconds, the blower engages.
  • It draws air into the furnace through the 'return air' ducts and pushes it across the now-heated heat exchanger.

Heat Transfer:

  • The heat exchanger in the furnace stores the warmth derived from the gas flame. When room-temperature air flows over the heat exchanger, it absorbs this stored heat, warming the circulating air.

Air Distribution:

  • The blower fan continues operating, distributing the warmed air throughout your home.

Thermostat Set Point Reached:

  • The blower persists until the thermostat registers the target temperature.

Gas Valve Closure:

  • Once the desired temperature is achieved, the gas valve gracefully closes.

Post-Flame Operation:

  • The blower runs for up to 360 seconds after the flame extinguishes.
  • This extended operation ensures the metal heat exchanger cools down and safety switches return to a safe temperature.
