What do HVAC ratings mean?

Technology

When it’s time for you to shop for a new home comfort system, you have a lot of different features to think about. Is it the correct size for your home? Will it provide the efficiencies you are looking for? Is the price point one you’re comfortable with? Will the system be quiet enough for your house? How will it impact the air quality? It can be overwhelming. 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 raise more questions for the average homeowner. Fortunately, the professionals at Premium Air Services LLC are breaking down the system ratings to provide more education as you head into the purchasing process:

Annualized Fuel Utilization Efficiency (AFUE): This efficiency rating is a ratio that compares how much of the fuel you use in your furnace to the amount turned into useable heat. You’ll find that the better systems have a higher percentage of heat used.

If your system has an AFUE rating of 85, that means the system converts 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 offers 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 a home comfort system is converted to cooling output. The higher your unit’s SEER, the more efficiently it runs.

Minimum SEER ratings change between regions. A high efficiency model that provides more energy savings in the long run will generally be a little more expensive. Lennox carries air conditioners with SEER ratings up to 26—another industry leading rating.

Heating Seasonal Performance Factor (HSPF): Have a heat pump? This is the heating efficiency rating you need to know. A higher rating indicates a more efficient heat pump. If you want to find a solution that’s ENERGY STAR® efficient, you’ll need 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 move around the house. MERV takes a look at the size of the holes. The higher the rating, the smaller the holes in the filter—and the fewer debris particles that make their way into your home. If you’re wanting a more efficient filter, find one with a MERV rating of 10 or higher.

Air filters are critical to keeping the air in your home clean and comfortable. Make sure to find the rating that works with your home, with your system and change the filter on a consistent basis.
