Air Authority’s Guide to SEER Ratings and HVAC Systems

If you’re in the market for a new air conditioner, you’ve probably come across the term “SEER” once or twice. Are you feeling confused? No worries! You’re certainly not alone. So let our experts at Air Authority dive in to help you better understand what an HVAC system’s SEER rating means and how it will affect you.

What Are SEER Ratings?

SEER stands for “Seasonal Energy Efficiency Ratio,” which measures an HVAC system’s overall efficiency. A SEER rating calculates by taking the total amount of heat removed from the conditioned space (expressed in Btu) and dividing it by the total electrical energy consumed during the same season (defined in watt-hours).

Keep in mind that an HVAC system’s SEER rating is its maximum efficiency rating. This means it could be less efficient depending on certain conditions, like your ductwork and the size of your home. As a result, even if your AC has the best SEER rating possible, you’ll still want to use other energy-saving tips during the peak summer season.

What Is a Good SEER Rating for HVAC Systems?

Generally speaking, the higher the SEER rating, the better. For example, most air conditioners have a SEER that’s anywhere from 13 to 21. However, according to the U.S. Energy Information Administration, the newest standards (effective in 2023) require a SEER rating of no less than 14 for residential systems in the northern U.S. and no less than 15 in the southern part of the U.S. 

However, a lower SEER rating doesn’t mean a system is inefficient. Even the most flawed SEER-rated HVAC system will still be more efficient than an older one that you purchased years ago.

If you’re searching for a new air conditioner or heat pump and the system’s SEER rating is important to you, keep in mind that any unit with a higher SEER rating than the system you currently have is a good purchase. It will still be more efficient and save you money down the line, even if it’s not the most efficient system available on the market.
