What do HVAC ratings mean?

Technology

When you’re searching for a new HVAC system, you have to consider a lot of factors. Is it the right size for your home? Will it be energy efficient? Will it work with your budget? Will the unit be quiet enough for your space? What kind of air quality can you expect? You have a lot to think about when considering the best solution. On top of all the questions 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 homeowner. Fortunately, the professionals at Abilene Air-Tech Inc 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. 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 turns 85 percent of the fuel used into useable heat. A system with an AFUE of 90 or higher is considered high efficiency. Lennox carries residential furnaces with ratings up to 98.7—the highest in the industry.

Seasonal Energy Efficiency Ratio (SEER): The SEER rating is used to measure both heat pumps and air conditioners. Much like AFUE, this ratio measures 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 vary 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 makes air conditioners with SEER ratings up to 26—another industry leading rating.

Heating Seasonal Performance Factor (HSPF): Looking into heat pumps? This is the rating to keep in mind. The higher your heat pump is rated, the more efficient it is. If you are in the market for a heat pump that’s ENERGY STAR® efficient, that requires 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 move within your indoor space. MERV takes a look at 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 wanting a more efficient filter, find one with a MERV rating of 10 or higher.

Air filters are key to indoor air quality. Make sure to find the rating that works with your home, with your system and change the filter frequently.

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