Here’s what you should know about AFUE & HVAC

As HVAC technology improves, so does the availability of heaters and air conditioners. Manufactured in countless different shapes and sizes, there are plenty of options out there from which to choose. But how you can you make a choice that’s right for both your home and your wallet?

When you’re completely stumped about the seemingly limitless array of opportunities, it’s important to know the different criteria in play. This is especially true when considering the efficiency of the heating models on the market using metrics like AFUE.

What Does AFUE Stand For?

AFUE stands for Annual Fuel Utilization Efficiency, a rating assigned to each heater model to denote the fuel efficiency ratio. Usually displayed on the EnergyGuide sticker on the front of the unit, this number effectively represents how fuel is used in generating heat.

For example, a unit with an AFUE of 80% indicates a heater in which 80% of the fuel used is converted into heat, while 20% is lost in the combustion process. AFUE varies from one brand and model to another, but in the U.S., the minimum allowable AFUE is 78%. A higher AFUE is considered to be a positive when comparing models.

What AFUE Means for You

AFUE is a significant metric when evaluating heaters. Models with lower AFUE often mean higher utility bills, as more energy is required for a substantial output. However, this isn’t always the case.

It’s important to note that electric heaters often have a very high AFUE rating due to the absence of a combustion process. In spite of this, these kinds of units may cost more due to the price difference in electricity versus gas, leading to higher utility costs over time.

In addition, other factors play into furnace efficiency and cost management than simply AFUE. Homeowners should know that a furnace blower fan’s electric use is generally not included in AFUE calculations, leading to higher utility bills than initially assumed. Shoppers should also consider other relevant metrics, like Heating Seasonal Performance Factor, a rating that looks into the heating efficiency of heat pumps.

AFUE is a vital metric in evaluating heaters, but professional help can ensure you find the right fit for you.
