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 correct 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 home? Will it be beneficial for your indoor air quality? You have a lot to think about when considering the best solution. On top of all the inquiries you have, some HVAC knowledge seems just out of reach. The acronyms and shorthand that industry professionals may include can create questions for the average individual. Lucky for you, the experts at True Temp Heating & Air Inc 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 links 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 converts 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 carries residential furnaces with ratings up to 98.7—the highest in the industry.

Seasonal Energy Efficiency Ratio (SEER): Both heat pumps and air conditioners use this rating. Similar to AFUE, this ratio measures 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 change 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): 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 are in the market for a heat pump 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 allow air and particles to circulate through your home. MERV measures 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 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.
