The Four Most Common HVAC Energy Efficiency Ratings

Published on March 24, 2015
The-Four-Most-Common-HVAC-Energy-Efficiency-Rating

When it comes to heating and cooling your home, homeowners usually enjoy opening their monthly energy bill to realize that it’s lower than they expected. After all, who doesn’t like saving money? As a homeowner, knowing can be half the battle, and in this case, understanding the most used HVAC energy efficiency ratings can help you save money when you get rid of your current system.

Of course, there are a large range of efficiencies for each heating and cooling product line, but because you’re a savvy homeowner, you can understand what you can pay for and what you’d like to use for your home. To help you with your education, here are the most commonly used HVAC energy efficiency ratings and a breakdown of what they mean:

Heating Seasonal Performance Factor (HSPF)*

HSPF is the rating developed to measure the energy efficiency of the heating part of your heat pump over one heating season. A higher HSPF rating points out that the system is functioning at a more efficient level than a lower rating. In the U.S., new systems have ratings ranging from the federal minimum of 7.7 to 9.4 for the systems with top efficiency.

Seasonal Energy Efficiency Ratio (SEER)*

This might be the most well-known of the energy efficiency ratings, as it measures the efficiency of your system over the cooling season. As with most ratings, the larger the SEER rating, the greater the efficiency. Now, the federal minimum for new systems is 13 SEER, and as technology continues to develop, the top rating continues to go higher, providing you with systems that can cool more efficiently and are more green. You can also expect to see lower energy costs with a higher SEER rating.

Annual Fuel Utilization Efficiency (AFUE)**

For heating systems that utilize gas or oil, AFUE is the rating that you should be on the lookout for. It references the amount of heat that your system offers for every dollar you spend on fuel. So if you have a system that has a high AFUE rating, it is wasting less fuel through its conversion process, which means savings for you month after month. There haven’t been any systems produced that perform without wasting any fuel, but the Lennox SLP98V operates with a 98.7% AFUE rating.

ENERGY STAR® Certification

While it’s not a rating, ENERGY STAR® certification is another way to know that you’re getting an energy efficient system. In 1992, the U.S. Environmental Protection Agency established ENERGY STAR so that businesses and homeowners could save money and protect the environment by using energy efficient products. ENERGY STAR certification has its own set of requirements that products must meet through third-party testing in a lab setting. These requirements are decided by region, so you know your system is ideal for the conditions in Hilton Head Island. Be on the lookout for a blue label with the ENERGY STAR logo on its packaging to know for sure.

Of course there are more ratings we could speak about, but these are a few of the most common HVAC energy efficiency ratings that we receive questions about at Epperson Service Experts Heating & Air Conditioning. If you have any questions about the right system or efficiency level for your home, feel free to give us a call at 843-619-3781 or schedule an appointment online with one of our pros.
