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? Is it energy efficient? How does the system work with your finances? Will the unit be quiet enough for your house? 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 factors you want to learn more about, some HVAC knowledge seems just out of reach. The acronyms and shorthand that industry professionals may include can be confusing for the average homeowner. Lucky for you, the team at Stephen Hurst Pack Heating and Cooling, 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. 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. 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 a home comfort system is converted to cooling output. The higher the SEER rating, the more efficient your system is operating.
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 offers air conditioners with SEER ratings up to 26—another industry leading rating.
Heating Seasonal Performance Factor (HSPF): Looking into heat pumps? This will be what you’ll want to take a look at as far as heating efficiency. You’ll want to look for heat pumps with a higher rating if efficiency is your goal. If you want a model that’s ENERGY STAR® efficient, you’ll need 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 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 make their way into your home. If you’re wanting 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 regularly.
