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 appropriate size for your home? Will it be 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? 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 already know can raise more questions for the average person. Lucky for you, the professionals at Rescue Heating & Air 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 compares 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 makes 85 percent of the fuel used into useable heat. Systems that are highly efficient have 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. Similar to AFUE, this ratio looks at how much of the fuel used to power an HVAC system is converted to cooling output. A more efficient system will have a higher SEER rating.
Minimum SEER ratings change between regions. High efficiency models are generally more expensive, but they provide more energy savings. Lennox offers air conditioners with SEER ratings up to 26—another industry leading rating.
Heating Seasonal Performance Factor (HSPF): Have a heat pump? This is the rating to keep in mind. The higher your heat pump is rated, the more efficient it is. 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 through your home. MERV measures 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 looking for a more efficient filter, find one with a MERV rating of 10 or higher.
Air filters are key 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 regularly.
