When it’s time to purchase a new furnace in Monroe, NC, you have a lot to consider. Along with who you’ll hire to install your new furnace, you should also consider the furnace’s efficiency rating. Every new furnace comes with an Annual Fuel Utilization Efficiency (AFUE) rating. It’s listed as a percentage, but what does that percentage mean?
What Does an AFUE Rating Measure?
Basically, this rating measures how efficient a furnace is at heating your home or business. For example, let’s say that your new furnace has an AFUE rating of 90%. This means that 90% of the energy that the furnace consumes is turned into heat for your home. The remaining 10% would be lost elsewhere, including heat lost through piping or ducts. Thus, quality heating systems have a higher AFUE rating.
Most low-rated furnaces have out-of-date features. For instance, new furnaces don’t have a continuous pilot light, which reduces how much fuel that they use while on standby.
What Is Considered a High AFUE Rating?
Typically, a system with an AFUE rating of 90% or higher is considered highly efficient. A midrange system typically has a rating of 80% to 89%. Any unit below that threshold is considered to have low efficiency. Compared to new systems, most old systems aren’t very efficient and have a relatively low AFUE rating.
Of course, upgrading your furnace doesn’t just lower your energy bills. It can reduce your family’s carbon footprint as well. Upgrading a gas furnace that has an AFUE of 56% to one that has a rating of 90% reduces your carbon emissions by 1.5 tons every year. If your furnace uses oil, an upgraded model could save 2.5 tons in carbon emissions per year.
