When it’s time for you to shop for a new home comfort system, you have to consider a lot of factors. Is it the correct size for your home? Will it be energy efficient? Will it work with your budget? Will the unit be quiet enough for your home? What kind of air quality can you expect? That’s a lot to think about. On top of all the questions you have, 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 Brogan Heating & AC Inc are breaking down the system ratings to give you a better understanding as you begin shopping:
Annualized Fuel Utilization Efficiency (AFUE): This efficiency rating is a ratio that associates 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. A system with an AFUE of 90 or higher is considered high efficiency. 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. Much like AFUE, this ratio compares how much of the fuel used to power a heating and cooling system is converted to cooling output. The higher your unit’s SEER, the more efficiently it runs.
Minimum SEER ratings vary between regions. Choosing a high efficiency model may be more expensive on the front end, but you’ll see greater energy savings throughout the years. 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 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 are in the market for a heat pump that’s ENERGY STAR® efficient, you’ll need 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 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 enter into your home. If you’re looking for a more efficient filter, find one with a MERV rating of 10 or higher.
Air filters are essential 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 frequently.
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.
