When you’re searching for a new HVAC system, you have a lot of different features to think about. Is it the right size for your home? Is it energy efficient? Will it work with your budget? Will the unit 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 may include can create questions for the average person. Fortunately, the experts at Arnold’s Air Conditioning of South Florida 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 compares how much of the fuel you use in your furnace to the amount turned into usable 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 turns 85 percent of the fuel used into usable heat. Systems that are highly efficient have 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): 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 an HVAC system is converted to cooling output. A more efficient system will have a higher SEER rating.
Minimum SEER ratings change 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 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 to find a solution 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 flow through your home. MERV measures 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 looking for a more efficient filter, find one with a MERV rating of 10 or higher.
Air filters are essential 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.
