When it’s time for you to shop for a new home comfort system, there are a lot of factors 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 system be quiet enough for your home? 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 already know can create questions for the average homeowner. Fortunately, the professionals at Jent Mechanical LLC 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 links 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 converts 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): The SEER rating is used to measure both heat pumps and air conditioners. Similar to AFUE, this ratio measures how much of the fuel used to power a home comfort system is converted to cooling output. The higher your unit’s SEER, the more efficiently it runs.
Minimum SEER ratings vary between regions. A high efficiency model that provides more energy savings in the long run will generally be a little more expensive. Lennox makes air conditioners with SEER ratings up to 26—another industry leading rating.
Heating Seasonal Performance Factor (HSPF): Looking into heat pumps? This will be what you’ll want to take a look at as far as heating efficiency. A higher rating indicates a more efficient heat pump. 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 allow 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 the fewer debris 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 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 frequently.
Finding an HVAC system that fits with your home, your energy efficiency needs and your desired comfort starts with understanding ratings.
