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 correct size for your home? Will it provide the efficiencies you are looking for? Is the price point one you’re comfortable with? Will the system 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 person. Fortunately, the professionals at Breathe Healthier Air 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 associates 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. A system with an AFUE of 90 or higher is considered high efficiency. 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. A lot like AFUE, this ratio compares 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. A high efficiency model that provides more energy savings in the long run will generally be a little more expensive. Lennox carries air conditioners with SEER ratings up to 26—another industry leading rating.
Heating Seasonal Performance Factor (HSPF): Have a heat pump? This is the heating efficiency rating you need to know. The higher your heat pump is rated, the more efficient it is. If you want a model 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 allow 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 the fewer debris particles that make their way into your home. If you’re seeking a more efficient filter, find one with a MERV rating of 10 or higher.
Air filters are critical 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.
Finding an HVAC system that fits with your home, your energy efficiency needs and your desired comfort starts with understanding ratings.
