Understanding Your Air Conditioner

What do HVAC ratings mean?

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? 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 to provide more education as you head into the purchasing process:



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.


Heating Seasonal Performance Factor (HSPF): Do you own a heat pump or plan to shop for one? This is the heating efficiency rating you need to know. 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, 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 measures 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 looking for a more efficient filter, find one with a MERV rating of 10 or higher.
