What Does AFUE Mean?
AFUE stands for annual fuel utilization efficiency. This rating system gives you a quick way to see how cost-effective an HVAC unit is.
Older, lower-tier furnaces typically have an AFUE of 56 to 70 percent. That means little more than half of the fuel they consume gets used. Not exactly the most productive use of resources. Fortunately, furnaces have come a long way since then, burning as high as 98.5 percent AFUE.
How Much Money Can a New Furnace Save You?
Our AFUE energy savings calculator can help determine how much you could save on your utility bills. Just enter your current unit’s AFUE value and compare it to a newer, more efficient system.
A new furnace does more than save you money on energy costs—it lowers your home’s carbon emissions. Switching out from your old 56 percent AFUE clunker to a 90 percent AFUE efficiency model can reduce your carbon footprint by a significant margin, according to the U.S. Department of Energy (DOE).
What Is a Variable Speed Furnace?
Single-stage furnaces only blow hot air at one speed. They are the most affordable upfront—but the most expensive to operate. Additionally, they have the most temperature variance, sometimes a 4 to 6 degrees difference between rooms.
Two-stage furnaces can distribute hot air at a full-speed or half-speed setting. This allows for more comfort and efficiency without breaking the bank.
Variable speed furnaces have fully dynamic and responsive blower speeds. This is the most energy-efficient option by far. Also, your home will be a near-uniform temperature, within a fraction of a difference between all rooms.
How Does a Furnace Work?
Gas furnaces heat using combustion. Once you set your thermostat, your furnace gets to work.
The ignitor lights the gas. Newer models use an electric starter to ignite, while older models use a pilot flame.
The combustion chamber lets in oxygen. This keeps the combustion efficient and clean. It also gets rid of byproducts, sending them through your flue.
The heat exchanger captures the heat rising from the combustion chamber. It has metal tubes that warm up. The heat from the tubes gets distributed through your air ducts with blowers.
