What do HVAC ratings mean?

Technology

When you’re searching for a new HVAC system, there are a lot of factors to think about. Is it the right size for your home? Will it be energy efficient? How does the system work with your finances? Will the system be quiet enough for your house? How will it impact the 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 use can raise more questions for the average individual. Fortunately, the experts at Bell Air Conditioning Inc. 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 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. A system with an AFUE of 90 or higher is considered high efficiency. Lennox carries residential furnaces with ratings up to 98.7—the highest in the industry.

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

Minimum SEER ratings vary between regions. High efficiency models are generally more expensive, but they provide more energy savings. Lennox offers air conditioners with SEER ratings up to 26—another industry leading rating.

Heating Seasonal Performance Factor (HSPF): Looking into heat pumps? This is the heating efficiency rating you need to know. A higher rating indicates a more efficient heat pump. If you are in the market for a heat pump 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 allow air and particles to move around the house. MERV measures the size of the holes. The higher the rating, the smaller the holes in the filter—and the fewer debris particles that enter into your home. If you’re seeking a more efficient filter, find one with a MERV rating of 10 or higher.

Air filters are essential to indoor air quality. Make sure to find the rating that works with your home, with your system and change the filter on a consistent basis.

These ratings will be important as you search for a solution that meets your needs.
