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 correct size for your home? Will it be energy efficient? How does the system work with your finances? Will the system be quiet enough for your house? Will it be beneficial for your indoor 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 already know can raise more questions for the average homeowner. Lucky for you, the team at LTS Plumbing & Heating Inc. 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. You’ll find that the better systems 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): Both heat pumps and air conditioners use this rating. Similar to AFUE, this ratio compares 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 differ 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): Do you own a heat pump or plan to shop for one? 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 are in the market for a heat pump 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 permit air and particles to circulate around the house. MERV takes a look at 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 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 on a consistent basis.
