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 appropriate size for your home? Is it energy efficient? Will it work with your budget? Will the unit be quiet enough for your home? What kind of air quality can you expect? That’s a lot to think about. On top of all the questions you have, some HVAC knowledge seems just out of reach. The acronyms and shorthand that industry professionals may include can raise more questions for the average person. Fortunately, the team at YES R&M Inc. 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. 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 carries 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 compares how much of the fuel used to power a home comfort system is converted to cooling output. The higher your unit’s SEER, the more efficiently it runs.
Minimum SEER ratings vary between regions. High efficiency models are generally more expensive, but they provide more energy savings. Lennox carries 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. A higher rating indicates a more efficient heat pump. If you want to find a solution 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 circulate around the house. 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 wanting a more efficient filter, find one with a MERV rating of 10 or higher.
Air filters are key to indoor air quality. Make sure to find the rating that works with your home, with your system and change the filter regularly.
Finding an HVAC system that fits with your home, your energy efficiency needs and your desired comfort starts with understanding ratings.
