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? Is the price point one you’re comfortable with? Will the HVAC system be quiet enough for your space? How will it impact the air quality? It can be overwhelming. 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 create questions for the average individual. Luckily, the professionals at Service Max Heating & Air Conditioning 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 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 converts 85 percent of the fuel used into useable heat. A system with an AFUE of 90 or higher is considered high efficiency. 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 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. Choosing a high efficiency model may be more expensive on the front end, but you’ll see greater energy savings throughout the years. 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 heating efficiency rating you need to know. You’ll want to look for heat pumps with a higher rating if efficiency is your goal. 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 allow air and particles to circulate through your home. MERV assesses 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 indoor air quality. Make sure to find the rating that works with your home, with your system and change the filter regularly.
