When you’re searching for a new HVAC 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 space? How will it impact the air quality? You have a lot to think about when considering the best solution. 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 create questions for the average person. Luckily, the team at SchagrinGAS Company 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. A better system will have a higher percentage of heat used.
If your system has an AFUE rating of 85, that means the system converts 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): This rating is used in both air conditioners and heat pumps. Similar to AFUE, this ratio looks at how much of the fuel used to power a heating and cooling system is converted to cooling output. A more efficient system will have a higher SEER rating.
Minimum SEER ratings vary 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): Looking into heat pumps? This is the rating to keep in mind. 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 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 a decrease in the number of 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 essential to indoor air quality. Make sure to find the rating that works with your home, with your system and change the filter frequently.
