What is SEER2?

SEER2 is an improvement over the previously used SEER rating, which stands for Seasonal Energy Efficiency Ratio. It's important to note that these numbers do not tell you how much electricity an AC unit will use; instead, they tell you how well it will cool your home based on its size and design. The higher the SEER number on your unit's label, the more efficient it will be at cooling your home, saving you money in energy costs over time!

SEER vs SEER2

The most significant difference between SEER and SEER2 ratings is that the latter takes into account all kinds of factors like humidity levels and climate conditions to accurately measure energy usage (and, therefore, savings). With this in mind, if you live somewhere where it gets really humid during certain seasons or even year-round--like me--it might actually make sense to buy something with a SEER2 rating higher than my current unit's SEER 16 instead of getting something cheaper but less efficient!

SEER2 is an improvement over SEER, but it's also more expensive.

SEER2 uses up to 20% less energy than its predecessor 

SEER2 costs about $100-$300 more per unit than regular AC's with the same capacity (i.e., 3 tons).
