Furnace

A heating appliance that warms air using natural gas, propane, oil, or electricity and distributes it through your home's ductwork.

What Is a Furnace?

A furnace is the most common type of central heating system in Southern Oregon homes. It works by burning fuel (usually natural gas) or using electric heating elements to warm air, which is then pushed through ductwork by a blower fan. Modern furnaces come in single-stage, two-stage, and variable-speed models, each offering different levels of comfort and efficiency. The efficiency of a furnace is measured by its AFUE rating — the higher the number, the more heat you get from every dollar spent on fuel.
