Common Furnace Repairs

While furnaces can last anywhere from 15-35 years, their internal parts do need a tuneup from time to time to keep them running at optimal efficiency
Its purpose is to provide the flame needed to light the gas coming out of the main burner. When the furnace "turns on", a valve releases gas into the burner and the pilot light ignites that gas.
Flame Sensor Ignitor
A Flame Sensor is a crucial safety feature on your gas heating equipment. During the ignition sequence, your gas furnace undergoes a process where either a spark or a hot surface igniter will actually ignite the gas. As the gas is ignited, the flame sensor creates a current of electricity.
A Blower Motor takes the heated or cooled air created within the furnace and circulates it throughout the home in order to ensure the temperature reaches what it is set at on the thermostat. it does this by spinning a fan, which blows the air through the ventilation system of your home.
The inducer motor is able to clear out any combustion gases that might be lingering in the heat exchanger from the previous heating cycle. Those gases are pushed into your system's flue pipes and vented out of your home
A pressure switch is designed to sense the negative pressure by the draft inducer motor during the furnace start up and to shut down the furnace ignitor, if the air pressure is inadequate.
