Understanding Your Air Conditioner

What do HVAC ratings mean?

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 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 already know can create questions for the average person. Lucky for you, the experts at Durable Service 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 converts 85 percent of the fuel used into useable heat. A system with an AFUE of 90 or higher is considered high efficiency. 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 a home comfort 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 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. A higher rating indicates a more efficient heat pump. If you want a model 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 permit air and particles to circulate 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 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 essential to the quality of air in your home. Make sure to find the rating that works with your home, with your system and change the filter frequently.
