  • Thermostat: This device is the control system for your home’s temperature. A temperature-activated switch tells a control board inside the furnace to start the heating cycle by turning on an ignition switch.
  • Draft/Hood Fan: Air is pulled into the burners and mixes with natural gas (the most common type of fuel source in NJ) to create combustion. The fan directs the heat from the burners into the heat exchanger where harmful, exhaust gases, like carbon monoxide (CO), are vented outside.
  • Burners: Furnace burners are a set of tubes where gas is directed to and then burned. A gas valve, igniter, and flame sensor all work together to control the flames. When your thermostat signals your heater to turn on, the gas valve opens and the mixture is ignited. The flame sensor acts as a safeguard that will shut off incoming gas if the flame isn’t present. Dirty burners and flame sensors are common repairs we often see.
  • Heat Exchanger: The burners heat a series of metal tubes in order to warm the air that is being pulled into the furnace. Any damage to the heat exchangers could let gases like CO leak into the house, which is why having a carbon monoxide detector is important to have in your home.
  • Blower: The blower fan will direct air that comes from the return ducts into the hot heat exchanger. The heated air is then blown throughout the home’s ductwork.
  • Flue: A flue vent collects the combustion gases used to create heat and send them outside of your home.
