In SEER ratings, what is the percentage difference between a 14 and a 16 SEER? How much more efficient is a higher number?Updated 9 months ago

For example purposes, we’ll be comparing 3-ton, 16-SEER vs 14-SEER air conditioners because they are popular sizes and choices in the Phoenix area. 

So, a 3-ton, 16-SEER unit in Phoenix saves you about $81 per year in electricity costs over a 14-SEER unit. 

Take into consideration how long you plan on being in your home and the price difference between the two air conditioners.
