How Does a Furnace Work?
Furnaces are exquisite appliances that often receive little attention while keeping you and your family warm and cozy. At least, that’s true until something breaks down. Knowing how one works and what you can do to maintain the unit will help it last longer.
The Process of Providing Heat
The furnace works on a basic process of circulating air through your home. It takes in cooler air and sends it out warmer. That seems simple enough. Here’s a more detailed explanation.
First, the furnace has to produce heat. When the thermostat sends a signal to turn on, the mechanism burns natural gas or propane to create that heat. As this happens, the heat warms up the heat exchanger.
This heat exchanger is responsible for actually heating the air. When it reaches the right temperature, the circulation fan activates and forces air through the exchanger.
The circulation fan then pushes this warm air out through the duct system into your home. While this is happening, that fan also draws cooler air through the return duct. This creates a circular flow of air throughout the house until the entire residence is at the right temperature.
Dealing With Problems
Like anything mechanical in your home, a furnace will malfunction eventually. At the first sign of trouble, be sure to check the batteries in your thermostat and the condition of your furnace filters. These control the activation signal to your furnace and its airflow, respectively. Either of them can inhibit the furnace’s function and potentially damage other components.
If both check out okay, it’s time to bring in trained professionals. All the other components in a furnace deal with the gas supply or the combustion mechanism. When untrained hands tinker with these, the results can be hazardous.
