The furnaces we install typically include a burner, blower, controls, and safety devices. A burner includes a heat exchanger, draft inducer, and venting that work together to produce hot gases, transform them into cool gases, and push them into venting pipes, which take them throughout the house. The blower draws air into the ductwork system and blows the air out through the heat exchanger and into the supply ductwork to be distributed throughout the home.
The controls our furnaces come with include a gas valve, ignition control, ignitor, flame sensor, transformer, limit control, blower control board, and flame roll-out switch. If the furnace overheats, our limit control will open the electrical circuit to the ignition control to stop gas flow.
