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 correct size for your home? Is it energy efficient? Will it work with your budget? Will the HVAC system be quiet enough for your space? 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 already know can create questions for the average individual. Luckily, the experts at West Jefferson Plumbing and Heating, 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 converts 85 percent of the fuel used into useable heat. Systems that are highly efficient have 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 measures how much of the fuel used to power a home comfort system is converted to cooling output. A more efficient system will have a higher SEER rating.
Minimum SEER ratings vary 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): Do you own a heat pump or plan to shop for one? 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 to find a solution 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 within your indoor space. MERV measures the size of the holes. The higher the rating, the smaller the holes in the filter—and fewer 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 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.
