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? How does the system work with your finances? Will the HVAC 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 factors you want to learn more about, some HVAC knowledge seems just out of reach. The acronyms and shorthand that industry professionals use can be confusing for the average individual. Fortunately, the professionals at Point Heating & Cooling 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 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 converts 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 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 an HVAC system is converted to cooling output. The higher the SEER rating, the more efficient your system is operating.
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 carries air conditioners with SEER ratings up to 26—another industry leading rating.
Heating Seasonal Performance Factor (HSPF): Have a heat pump? This will be what you’ll want to take a look at as far as heating efficiency. The higher your heat pump is rated, the more efficient it is. 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 move through your home. MERV takes a look at 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 seeking a more efficient filter, find one with a MERV rating of 10 or higher.
Air filters are essential 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.
