What do HVAC ratings mean?

Technology

If you are looking for a new heating and cooling system, you have a lot of different features to think about. Is it the right size for your home? Is it energy efficient? Will it work with your budget? Will the HVAC system be quiet enough for your home? Will it be beneficial for your indoor air quality? You have a lot to think about when considering the best solution. On top of all the factors you want to learn more about, some HVAC knowledge seems just out of reach. The acronyms and shorthand that industry professionals already know can create questions for the average homeowner. Lucky for you, the team at J.L. Brady Company LLC are breaking down the system ratings you need to know before making a purchase:

Annualized Fuel Utilization Efficiency (AFUE): This efficiency rating is a ratio that associates how much of the fuel you use in your furnace to the amount turned into useable heat. A better system will have a higher percentage of heat used.

If your system has an AFUE rating of 85, that means the system turns 85 percent of the fuel used into useable heat. If you are looking for a highly efficient system, you’ll want one that has an AFUE of 90 or higher. Lennox carries residential furnaces with ratings up to 98.7—the highest in the industry.

Seasonal Energy Efficiency Ratio (SEER): This rating is used in both air conditioners and heat pumps. A lot like AFUE, this ratio compares how much of the fuel used to power an HVAC system is converted to cooling output. A more efficient system will have a higher SEER rating.

Minimum SEER ratings vary between regions. Choosing a high efficiency model may be more expensive on the front end, but you’ll see greater energy savings throughout the years. Lennox offers air conditioners with SEER ratings up to 26—another industry leading rating.

Heating Seasonal Performance Factor (HSPF): Do you own a heat pump or plan to shop for one? This is the heating efficiency rating you need to know. The higher your heat pump is rated, the more efficient it is. If you want a model that’s ENERGY STAR® efficient, that requires a rating above an 8.2—as well as a SEER rating above 12.

Minimum Efficiency Reporting Value (MERV): Air filters have holes that let air and particles to circulate around the house. MERV assesses the size of the holes. The higher the rating, the smaller the holes in the filter—and fewer particles that enter into your home. If you’re wanting a more efficient filter, find one with a MERV rating of 10 or higher.

Air filters are essential to the quality of air in your home. Make sure to find the rating that works with your home, with your system and change the filter regularly.
