If you are looking for a new heating and cooling system, you have to consider a lot of factors. Is it the correct size for your home? Will it be energy efficient? How does the system work with your finances? Will the system be quiet enough for your home? 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 create questions for the average homeowner. Fortunately, the team at Scott Temperature 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 links 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. 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): Both heat pumps and air conditioners use this rating. Much like AFUE, this ratio compares how much of the fuel used to power a heating and cooling system is converted to cooling output. The higher your unit’s SEER, the more efficiently it runs.
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 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, 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 through your home. MERV measures the size of the holes. The higher the rating, the smaller the holes in the filter—and a decrease in the number of particles that make their way 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 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 frequently.
