Understanding Your Air Conditioner

What do HVAC ratings mean?

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? Is it energy efficient? How does the system work with your finances? Will the system be quiet enough for your space? What kind of air quality can you expect? That’s a lot to think about. 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. Lucky for you, the professionals at Cool Power LLC 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. 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 carries residential furnaces with ratings up to 98.7—the highest in the industry.

Seasonal Energy Efficiency Ratio (SEER): The SEER rating is used to measure both heat pumps and air conditioners. Similar to AFUE, this ratio compares 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. A high efficiency model that provides more energy savings in the long run will generally be a little more expensive. Lennox offers air conditioners with SEER ratings up to 26—another industry leading rating.

Heating Seasonal Performance Factor (HSPF): Have a heat pump? This is the heating efficiency rating you need to know. The higher your heat pump is rated, the more efficient it is. If you want a model 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 circulate through your home. 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 make their way 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 critical 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 on a consistent basis.

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.
