What do HVAC ratings mean?

Technology

If you are looking for a new heating and cooling system, you have to consider a lot of factors. Is it the appropriate size for your home? Is it energy efficient? Will it work with your budget? Will the system be quiet enough for your house? What kind of air quality can you expect? It can be overwhelming. 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 be confusing for the average individual. Fortunately, the experts at Effective Service Group, LLC 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 associates how much of the fuel you use in your furnace to the amount turned into useable heat. The higher the percentage of heat used, the better the system rating.

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 offers 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. 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. A more efficient system will have a higher SEER rating.

Minimum SEER ratings change between regions. Choosing a high efficiency model may be more expensive on the front end, but you’ll see greater energy savings throughout the years. Lennox carries air conditioners with SEER ratings up to 26—another industry leading rating.

Heating Seasonal Performance Factor (HSPF): Do you own a heat pump or plan to shop for one? 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 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 within your indoor space. 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 get into your home. If you’re seeking 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 on a consistent basis.

These ratings will be important as you search for a solution that meets your needs.
