How Does a Furnace Work?
Your furnace may seem magical in its ability to produce and maintain heat. However, it is quite simple science at work. Peek behind the curtain and understand how it works.
The Simple Process of Heating With a Furnace
Most modern furnaces use a process called “forced air” heating. This name comes from it forcing air through the system and space. These furnaces use the following process to heat your home.
First, it has to produce the heat. The thermostat sends a signal to the furnace to start the burner when heat is needed. That burner is much like what you find on a gas grill. That heat then travels up to the heat exchanger.
The heat exchanger warms the air that is forced through it by the circulating fan. The circulating fan continues to force that warmed air through the ducts and out into your home.
The circulating fan also draws cool air through the return duct. Most furnaces have the air filter located somewhere in the return duct system. This is usually at either the return register or just before the combustion chamber.
The biggest key is the circulating fan. It keeps cool air moving into the furnace and warm air out into the space.
What Happens When It Doesn’t Work?
Check the air filter and thermostat as a first step any time there is a problem with your furnace. Without proper airflow or signal, the furnace will not run. These are parts anyone can check and fix.
If both of these are good, you want to call a trained professional. Without proper training, trying to do it yourself can result in hazardous leaks and additional broken parts. This is both dangerous and costly.
