Is a higher SEER2 worth it?

For homes that use AC heavily (most of Asheville's summer), yes — higher efficiency pays back through lower bills. We help you compare the payback for your home.

What's the difference between SEER and SEER2?

SEER2 is the updated testing standard that better reflects real-world conditions. All new systems now use the SEER2 rating.

What Is SEER2?

SEER2 (Seasonal Energy Efficiency Ratio 2) is the current standard for measuring air conditioner and heat pump cooling efficiency. The higher the SEER2 rating, the more cooling you get per unit of electricity — meaning lower energy bills, especially through Asheville's long cooling season.

What Ratings Are Available?

Today's minimum efficiency starts around 14 SEER2. Standard systems range from 14–16 SEER2, while high-efficiency systems range from 16 to 20+ SEER2. Higher ratings generally use variable-speed compressors that run quieter and more efficiently.

How to Choose the Right Rating

The right SEER2 rating balances upfront cost with long-term savings. A higher rating costs more upfront but lowers monthly bills. For homes that run the AC a lot (most of Asheville's humid summer), higher efficiency pays back faster. For lightly used systems, a standard rating may be the better value. We help you compare the payback based on your home and energy use.
