If you are looking for a new heating and cooling system, there are a lot of factors to think about. Is it the right size for your home? Will it provide the efficiencies you are looking for? How does the system work with your finances? Will the HVAC system be quiet enough for your home? How will it impact the air quality? It can be overwhelming. 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 use can raise more questions for the average person. Fortunately, the professionals at Bon Air Service Company 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 associates 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 turns 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 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. A lot like AFUE, this ratio measures how much of the fuel used to power a home comfort system is converted to cooling output. A more efficient system will have a higher SEER rating.
Minimum SEER ratings vary 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 will be what you’ll want to take a look at as far as heating efficiency. The higher your heat pump is rated, the more efficient it is. If you want a model 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 move through your home. MERV measures the size of the holes. The higher the rating, the smaller the holes in the filter—and the fewer debris particles that get 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 critical to indoor air quality. Make sure to find the rating that works with your home, with your system and change the filter regularly.
