When you’re searching for a new HVAC system, you have a lot of different features to think about. Is it the correct size for your home? Is it energy efficient? Is the price point one you’re comfortable with? Will the system be quiet enough for your home? What kind of air quality can you expect? It can be overwhelming. 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 raise more questions for the average individual. Lucky for you, the team at Lanz Furnace and Fireplace 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. 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 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): The SEER rating is used to measure both heat pumps and air conditioners. Much like AFUE, this ratio looks at how much of the fuel used to power an HVAC system is converted to cooling output. The higher your unit’s SEER, the more efficiently it runs.
Minimum SEER ratings change between regions. High efficiency models are generally more expensive, but they provide more energy savings. 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 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, 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 fewer particles that get into your home. If you’re wanting 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.
