If you are looking for a new heating and cooling system, you have to consider a lot of factors. Is it the right size for your home? Is it energy efficient? How does the system work with your finances? 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 inquiries you have, some HVAC knowledge seems just out of reach. The acronyms and shorthand that industry professionals use can be confusing for the average person. Fortunately, the professionals at Ilten's Incorporated 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 turns 85 percent of the fuel used into useable heat. Systems that are highly efficient have an AFUE of 90 or higher. Lennox carries 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. 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 differ 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): Have a heat pump? This is the rating to keep in mind. The higher your heat pump is rated, the more efficient it is. If you want to find a solution 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 let air and particles to move 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 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 critical to indoor air quality. Make sure to find the rating that works with your home, with your system and change the filter on a consistent basis.
