What You Need to Know About Furnaces

Most furnaces in Georgia and South Carolina run on natural gas because it is widely available and tends to be the most economical choice. A well-maintained gas furnace should operate efficiently for 15 to 30 years before you need to replace it.

You can trust our NATE (North American Technician Excellence) certified team of professionals to choose a furnace that takes into account the size of your home and existing air ducts, or ductwork. A properly sized furnace delivers warmth and comfort without wasting energy and overworking itself. Our professionals will calculate the square footage in your home and how well each room is insulated to determine the right-size furnace for your needs.

High-efficiency furnaces deliver warmth and save money on your heating bills. To understand your furnace efficiency, you need to know your furnace’s annual fuel utilization efficiency (AFUE) rating. A furnace with a 95 percent AFUE rating can convert 95 percent of the energy it consumes into heat.

The higher the AFUE rating, the more money you save on energy bills. Keep in mind that maintaining your ductwork and properly sealing the windows and doors in your home are key factors in energy efficiency. If your home is poorly insulated, your furnace will struggle.

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. Simply enter your current unit's AFUE value and compare it to a newer, more efficient system. You can even customize it to better match your home's system for a more accurate calculation.
