Let me explain how furnaces work

The furnace is a very cool invention that has completely changed how we heat our houses today.

Without furnaces, we would still be in the dark ages when it comes to heating our homes.

Many people take their furnaces front granted, and they have no idea what their furnace does to keep their house warm. If their furnace breaks down, the only person that understands how and why furnaces work and break down are the HVAC technicians. Well, today, I am going to explain how your furnaces work so that you will have a better understanding and appreciation for how you stay warm. First, it all starts with the fuel. On gas-burning furnaces, a small spark is created inside the combustion chamber that ignites the natural gas inside. Once the flame reaches a certain temperature, a component of the furnace tells the furnace to add more fuel to create a larger fire. As the heat from this fire is generated, it is forced throughout your home in HVAC ducts and vents with a blower. While there are many different components, this is the basic function of your furnace. With an electric furnace, the process is very similar. The only difference is that the electricity heats up coils that air is passed through to create heat. In both furnaces, the thermostat is the device that signals to your furnace that it is time to kick on and start heating your house. Isn’t that so cool? I wish that I could have been the one to discover how to create a furnace. The whole HVAC unit is a genius idea.
