How furnace works
A furnace is a device used to heat a space or building. It burns fuel, such as natural gas, oil, or propane, to create heat. The heat is then distributed throughout the building using a system of ducts and vents.
The furnace has several components, including the burner, heat exchanger, blower, and thermostat. When the thermostat senses that the temperature in the building is lower than the desired temperature, it sends a signal to the furnace to start heating.
The burner ignites the fuel, which creates a flame that heats the heat exchanger. The heat exchanger is a metal component that allows the heat from the burner to transfer to the air blown over it.
The blower then pushes the heated air through the ducts and vents, distributing it throughout the building. Once the desired temperature is reached, the thermostat signals the furnace to stop heating.
Regular furnace maintenance is important to ensure its proper functioning and efficiency. This includes changing the air filter, cleaning the ducts, and having a professional inspection and cleaning of the furnace components.
