What do HVAC ratings mean?

Technology

When it’s time for you to shop for a new home comfort system, you have to consider a lot of factors. Is it the right size for your home? Is it energy efficient? Is the price point one you’re comfortable with? Will the unit be quiet enough for your home? Will it be beneficial for your indoor air quality? That’s a lot to think about. On top of all the questions you have, some HVAC knowledge seems just out of reach. The acronyms and shorthand that industry professionals already know can raise more questions for the average individual. Lucky for you, the experts at Eco Fresh HVAC 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 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 makes 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 has 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. Similar to AFUE, this ratio looks at how much of the fuel used to power a heating and cooling 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 carries air conditioners with SEER ratings up to 26—another industry leading rating.

Heating Seasonal Performance Factor (HSPF): Looking into heat pumps? This will be what you’ll want to take a look at as far as heating efficiency. 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 within your indoor space. 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 get into your home. If you’re looking for a more efficient filter, find one with a MERV rating of 10 or higher.

Air filters are key 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.
