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? Is it energy efficient? Is the price point one you’re comfortable with? Will the system be quiet enough for your home? How will it impact the air quality? You have a lot to think about when considering the best solution. On top of all the questions you have, some HVAC knowledge seems just out of reach. The acronyms and shorthand that industry professionals may include can be confusing for the average homeowner. Fortunately, the professionals at C&C Refrigeration 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. 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. Systems that are highly efficient have 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): The SEER rating is used to measure both heat pumps and air conditioners. Much like AFUE, this ratio looks at how much of the fuel used to power a heating and cooling system is converted to cooling output. The higher the SEER rating, the more efficient your system is operating.

Minimum SEER ratings vary between regions. A high efficiency model that provides more energy savings in the long run will generally be a little more expensive. 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 rating to keep in mind. You’ll want to look for heat pumps with a higher rating if efficiency is your goal. If you want to find a solution that’s ENERGY STAR® efficient, then look for a model with 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 through your home. MERV takes a look at the size of the holes. The higher the rating, the smaller the holes in the filter—and a decrease in the number of particles that enter 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 regularly.

Keeping these ratings in mind as you begin looking for a new system will help ensure you find one that meets your needs and will work with your home.
