Understanding Air Conditioner Efficiency Ratings

Understanding Air Conditioner Efficiency Ratings

Choosing an A/C that will suit your home can be difficult—especially if you have no idea about air conditioner ratings. Below is a rundown of air conditioning that will help you determine which cooling equipment fits your needs and lifestyle.


Seasonal Energy Efficiency Ratio (SEER) refers to the primary efficiency rating applied to split-type A/C systems. To calculate the SEER of an air conditioner, simply divide the cooling output by the electrical power that goes into the equipment. The higher the number, the more efficient your A/C is.

What Does Energy Star Mean for Air Conditioners?

HVAC manufacturers are ideally not allowed to sell split-system A/Cs with SEER numbers lower than 14. The SEER must be at least 15 to qualify for the federal government’s energy-efficiency credential.

With incremental surges in SEER that amounts to hundreds of dollars, high-efficiency systems do cost money. When looking for a new central A/C, you have to think of how much you will get out of your new system.

If you want to run your cooling system continuously while expecting to live in the same home for several years, then you should try investing in a high-SEER air conditioning. As time passes, the lower operating costs will pay for the additional upfront cost. However, if you do not plan to stay in the same home for a couple of years, it would be best to choose a low-end SEER system.
