Energy Efficient Furnaces

Posted on: January 10, 2013

If your old furnace isn’t operating very efficiently and you are considering upgrading to a new energy efficient furnace, there are many things you need to consider before making a decision. Below are several things you should keep in mind when you are looking for furnace installation in San Diego.

Annual Fuel Utilization Efficiency (AFUE)

AFUE is a measurement of how well a furnace—or any other gas appliance—converts fuel to heat over the course of a year. AFUE is the industry standard for measuring a furnace’s efficiency. New furnaces are required by law to state their AFUE and provide a comparison to other models of furnaces. You’ve probably seen this on appliances in the past and never realized what it was:

In this example, this furnace s 82.7 percent efficient, which ranks pretty low compared to other models on the market. Today, a good AFUE rating is between 90 and 98 percent.

These ENERGYGUIDE stickers are required by the U.S. Department of Energy with the goal of helping consumers make decisions with energy efficiency in mind when upgrading appliances. We carry many energy efficient brands of furnaces. Schedule a free consultation with our furnace professionals today to learn more about the brands and models we carry.

Energy Efficiency Steps You Should Take Before You Buy

Keep in mind, however, the AFUE rating measures only the efficiency of the furnace itself. If your home has leaky duct work or piping, your heating system may not operate as efficiently as you would expect. Before you upgrade to a new energy efficient furnace model, you should improve the energy efficiency of your home by sealing air leaks in your ducts and around windows and adding insulation. Improving the energy efficiency of your home will help your furnace professional more easily determine the size of heating system you need. A more efficient home will also require a smaller furnace—decreasing upfront costs as well as ongoing heating costs!

How to Keep Your Furnace Operating Efficiently

Even very efficient furnaces can operate inefficiently if they are not properly maintained. The best way to keep your furnace operating as efficiently as possible is to have regular furnace maintenance. Keeping your baseboards, air registers, and air filters maintained and cleaned annually can shave hundreds off your annual heating costs. After having a new energy efficient furnace installed, we recommend signing up for our HVAC maintenance plan to keep your system operating at peak performance for longer.

Why Upgrade?

Still not convinced? An energy efficient furnace can actually cut your heating bill in half! Beyond the financial reasons, there are health and environmental reasons to consider as well. Older furnaces can develop leaks that could lead to carbon monoxide poisoning or other health problems. Old inefficient furnaces also produce far more carbon dioxide emissions and smog particulate that create poor air quality problems. A new energy efficient furnace benefits not only your finances, but also your family and neighbors!
