Definition
Seasonal Energy Efficiency Ratio 2 — the current standard rating for cooling efficiency over a season. Higher SEER2 means lower summer cooling costs.
Why this matters for your home
SEER2 is the current standard for rating cooling efficiency across a full season, replacing the older SEER metric with more realistic test conditions. The higher the SEER2, the less electricity the system uses to deliver the same cooling.
For a Minnesota home, a higher-SEER2 unit costs more upfront but trims summer electric bills, and the payback depends on how heavily you cool. We help you weigh the rating against your usage and any available rebates so you're not overpaying for efficiency you won't recover.
