When you’re searching for a new HVAC system, there are a lot of factors 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 house? What kind of air quality can you expect? 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 be confusing for the average individual. Fortunately, the professionals at Goode Bros AC & Heating 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. 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. If you are looking for a highly efficient system, you’ll want one that has 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): This rating is used in both air conditioners and heat pumps. Similar to AFUE, this ratio compares how much of the fuel used to power a heating and cooling system is converted to cooling output. The higher the SEER rating, the more efficient your system is operating.
Minimum SEER ratings vary 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 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. A higher rating indicates a more efficient heat pump. 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 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 enter into your home. If you’re seeking a more efficient filter, find one with a MERV rating of 10 or higher.
Air filters are essential to indoor air quality. Make sure to find the rating that works with your home, with your system and change the filter on a consistent basis.
