If you are looking for a new heating and cooling system, you have to consider a lot of factors. 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 house? How will it impact the 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 may include can create questions for the average individual. Fortunately, the experts at Home Comfort Heating & Air are breaking down the system ratings to provide more education as you head into the purchasing process:
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. 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 turns 85 percent of the fuel used into useable heat. A system with an AFUE of 90 or higher is considered high efficiency. Lennox has 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. A lot like AFUE, this ratio compares 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 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 makes air conditioners with SEER ratings up to 26—another industry leading rating.
Heating Seasonal Performance Factor (HSPF): Looking into heat pumps? This is the rating to keep in mind. 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, 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 allow air and particles to circulate around the house. MERV measures the size of the holes. The higher the rating, the smaller the holes in the filter—and the fewer debris particles that get into your home. If you’re seeking 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.
Keeping these ratings in mind as you begin looking for a new system will help ensure you find one that meets your needs and will work with your home.
