When it’s time for you to shop for a new home comfort system, you have a lot of different features to think about. Is it the appropriate size for your home? Is it energy efficient? How does the system work with your finances? Will the unit be quiet enough for your space? How will it impact the air quality? 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 Solar Air Inc. 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 compares 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 makes 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. Much like 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. Choosing a high efficiency model may be more expensive on the front end, but you’ll see greater energy savings throughout the years. Lennox offers 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 is the rating to keep in mind. A higher rating indicates a more efficient heat pump. 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 allow air and particles to circulate 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 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 essential 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.
