If you are looking for a new heating and cooling system, you have a lot of different features to think about. Is it the correct size for your home? Will it provide the efficiencies you are looking for? Will it work with your budget? Will the system be quiet enough for your home? Will it be beneficial for your indoor air quality? It can be overwhelming. On top of all the inquiries you have, some HVAC knowledge seems just out of reach. The acronyms and shorthand that industry professionals may include can be confusing for the average individual. Fortunately, the experts at Osceola Air, 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 compares 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. 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): Both heat pumps and air conditioners use this rating. 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 differ between regions. High efficiency models are generally more expensive, but they provide more energy savings. Lennox offers 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. You’ll want to look for heat pumps with a higher rating if efficiency is your goal. If you want to find a solution 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 allow air and particles to flow around the house. MERV assesses 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 enter 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 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 regularly.
Keeping these ratings in mind as you begin looking for a new system will help ensure you find one that meets your needs and will work with your home.
