Are you contrasting the efficiency ratings of new HVAC systems? Perhaps you want to check the rating on your current HVAC system. Either way, you can determine the efficiency rating and expected yearly operating costs by checking the yellow Energy Guide label along the side of the unit. Here's more information about the various ratings you might read and what they mean.
What Is a SEER Rating?
SEER is an acronym for Seasonal Energy Efficiency Ratio, a measurement of air conditioning efficiency. The SEER rating represents the cooling output of an air conditioner over an entire cooling season, divided by the total amount of energy utilized within that time frame. A higher SEER rating indicates considerably better energy efficiency and lower energy bills.
Today, the minimum SEER rating for recently manufactured air conditioners is 14 SEER in the northern U.S. and 15 SEER in the southern U.S. This is an improvement from the past minimum expectation of 13 SEER in the north and 14 SEER in the south, which was in effect from 2015 to 2022. This modification demonstrates the U.S Department of Energy’s (DOE) ongoing efforts to minimize energy consumption and greenhouse gas emissions.
These days, high-end air conditioners boast ratings of 26 SEER or higher, providing remarkable energy savings. But bear in mind, exceptional SEER ratings normally come with a higher up-front cost. This means you should look at both the initial financial investment and the potential for ongoing savings when choosing a new air conditioner.
What Is an EER Rating?
Even though SEER ratings are more known to consumers, there's a different efficiency measurement you should be aware of. It’s called EER, and it is short for Energy Efficiency Ratio. This rating suggests the effectiveness of an cooling system under distinct operating situations. The EER rating enables you to understand whether the system will handle the demand on the hottest summer days.
Presently, only the southwest area of the nation has a minimum EER rating of 12.2 EER for residential central air conditioners. Peak ratings top out at about 14 EER. Consider that SEER and EER for the most part correspond, with higher ratings signifying stronger overall performance.
What Is an HSPF Rating?
Heating Seasonal Performance Factor (HSPF) ratings are measurements of the energy efficiency of air-source heat pumps when in heating mode. HSPF is a proportion of the overall heat output in British Thermal Units (BTUs) over the heating season to the amount of electricity used in watt-hours. A higher HSPF rating means a more efficient heat pump.
The minimum HSPF rating for new heat pumps is 8.8 HSPF, a boost from the prior minimum of 8.2 HSPF. By calling for higher minimum HSPF ratings, the DOE wants to motivate people to use more energy-efficient heating systems in homes and businesses across the U.S Settling for less efficiency remains an option, but it's a wise choice to invest in a high-end heat pump with a rating of 13 HSPF or higher for the greatest performance.
What Is an AFUE Rating?
Annual Fuel Utilization Efficiency (AFUE) ratings are yet another standard of heating system efficiency, but they only pertain to furnaces and boilers. AFUE is a proportion of the yearly heat output to the energy utilized during that period. The greater the AFUE rating, the more efficient the heating unit(s).
In 2023, the minimum AFUE rating for new gas furnaces has been modified to 81. Previously, the south and southwest had a minimum of 80 AFUE, and the northern states required ratings of 90 AFUE or higher. While you aren't required to install anything above the minimum, you’ll spend less on your heating bills by selecting a furnace rated 95 AFUE or higher.
What Is an ENERGY STAR¨ Rating?
The Environmental Protection Agency (EPA) introduced the ENERGY STAR program in the early 1990s to help homeowners and businesses discover the most energy-efficient equipment and appliances available. HVAC equipment, appliances, water heaters, light fixtures, office equipment, electronics and building products that have a minimum threshold of efficiency can earn ENERGY STAR certification.
ENERGY STAR-rated products go above and beyond the minimum requirements to save energy and decrease emissions without limiting performance or features. You can also look for the ENERGY STAR Most Efficient designation, which recognizes the best performers in energy efficiency and innovation. The EPA is actually revising the qualification requisites given the new minimum HVAC efficiency standards.
