When it comes to heating your home, everyone enjoys opening their monthly energy bill to realize that it’s lower than they envisioned. After all, who doesn’t like saving money? As a homeowner, knowing can be half the battle, and in this case, understanding the most utilized HVAC energy efficiency ratings can help you save money when the time comes to replace 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 budget for and what you’d like to use for your home. To help you with your learning, 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 utilized to measure the energy efficiency of the heating part of your heat pump over one heating season. A larger 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 the greatest efficiency.
Seasonal Energy Efficiency Ratio (SEER)*
This could 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 grow, 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 operate with gas or oil, AFUE is the rating that you should be looking for. It references the amount of heat that your system provides 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 indication 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 set by region, so you know your system is perfect for the conditions in Pierre. Be on the lookout for a blue label with the ENERGY STAR logo on its packaging to know for sure.
