What do HVAC ratings mean?

Technology

If you are looking for a new heating and cooling system, you have a lot of different features to think about. 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? Will it be beneficial for your indoor 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 may include can raise more questions for the average person. Fortunately, the professionals at Osceola Air, LLC are breaking down the system ratings you need to know before making a purchase:

Annualized Fuel Utilization Efficiency (AFUE): This efficiency rating is a ratio that associates 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. 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): 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 vary between regions. High efficiency models are generally more expensive, but they provide more energy savings. Lennox makes air conditioners with SEER ratings up to 26—another industry leading rating.

Heating Seasonal Performance Factor (HSPF): Have a heat pump? This will be what you’ll want to take a look at as far as heating efficiency. 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 allow air and particles to move through your home. MERV assesses the size of the holes. The higher the rating, the smaller the holes in the filter—and the fewer debris particles that enter into your home. If you’re wanting 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 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.
