If you are looking for a new heating and cooling system, you have a lot of different features to think about. Is it the correct size for your home? Will it be energy efficient? Is the price point one you’re comfortable with? Will the system be quiet enough for your space? How will it impact the air quality? You have a lot to think about when considering the best solution. On top of all the inquiries 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. Lucky for you, the team at Four Seasons Air Conditioning and Heating LLC 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 links 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. Systems that are highly efficient have an AFUE of 90 or higher. 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 an HVAC system is converted to cooling output. A more efficient system will have a higher SEER rating.
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 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. You’ll want to look for heat pumps with a higher rating if efficiency is your goal. If you want a model 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 permit air and particles to circulate through your home. MERV measures 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 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 on a consistent basis.
These ratings will be important as you search for a solution that meets your needs.
