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? Will it provide the efficiencies you are looking for? How does the system work with your finances? Will the HVAC system be quiet enough for your space? How will it impact the air quality? That’s a lot to think about. On top of all the inquiries you have, some HVAC knowledge seems just out of reach. The acronyms and shorthand that industry professionals already know can create questions for the average person. Lucky for you, the experts at Cool Air Solutions are breaking down the system ratings to give you a better understanding as you begin shopping:

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 converts 85 percent of the fuel used into useable heat. Systems that are highly efficient have 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): This rating is used in both air conditioners and heat pumps. Much like AFUE, this ratio compares how much of the fuel used to power an HVAC system is converted to cooling output. The higher your unit’s SEER, the more efficiently it runs.

Minimum SEER ratings differ 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): 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 a model 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 move around the house. MERV measures 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 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 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.
