What You Need to Know About Gas Furnaces

Most furnaces in Michigan run on natural gas because it’s widely available and tends to be the most economical choice. A properly maintained heating system should operate for 15 to 20 years before you need to replace it.

As a smart Farmington Hills, MI, homeowner, you will want to know your furnace’s annual fuel utilization efficiency (AFUE) rating. An energy-efficient furnace will have an AFUE rating of 95 percent or higher, meaning it can convert 95 percent of the energy it consumes into heat.

The higher the AFUE rating, the more money you save on monthly utility bills. They also help the environment since they emit a lesser amount of greenhouse gases into the atmosphere.

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.
