When it comes to heating your home, everyone enjoys opening their monthly energy bill to realize that it’s less 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 common HVAC energy efficiency ratings can help you save money when it comes time to replace your current system.
Of course, there are a wide range of efficiencies for each heating and cooling product line, but because you’re an informed homeowner, you can understand what you can afford 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 an explanation of what they mean:
HSPF is the rating used to measure the energy efficiency of the heating portion of your heat pump over one heating season. A higher HSPF rating indicates 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.
This may 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 higher the SEER rating, the greater the efficiency. Currently, the federal minimum for new systems is 13 SEER, and as technology continues to evolve, the top rating continues to go higher, providing you with systems that can cool more efficiently and are better for the environment. You can also expect to see lower energy costs with a higher SEER rating.
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 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 during its conversion process, which means savings for you month after month. There haven’t been any systems developed that perform without wasting any fuel, but the Lennox SLP98V operates with a 98.7% AFUE rating.
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 determined by region, so you know your system is optimized for the conditions in Canada. Be sure to look for a blue label with the ENERGY STAR logo on its packaging to know for sure.
