When it’s time for you to shop for a new home comfort system, there are a lot of factors to think about. Is it the correct size for your home? Will it be energy efficient? How does the system work with your finances? Will the unit 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 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 individual. Lucky for you, the team at Central Air 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 compares 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 offers 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. A lot like AFUE, this ratio looks at how much of the fuel used to power an HVAC system is converted to cooling output. The higher the SEER rating, the more efficient your system is operating.
Minimum SEER ratings differ 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): Looking into heat pumps? This is the heating efficiency rating you need to know. 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, 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 allow air and particles to circulate around the house. 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 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 essential to keeping the air in your home clean and comfortable. 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.
