HVAC Efficiency & SEER Ratings
HVAC Efficiency, SEER & SEER2 Ratings in Wisconsin
Understanding SEER and SEER2 ratings helps you choose the right air conditioning or heat pump system for your home.
SEER (Seasonal Energy Efficiency Ratio) and SEER2 measure how efficiently an air conditioning system or heat pump cools your home over a typical season. Higher ratings indicate greater energy efficiency.

SEER vs. SEER2 — What’s the Difference?
As of 2023, federal efficiency standards use SEER2, which reflects updated testing procedures that more accurately represent real-world performance.
SEER2 ratings are slightly lower than older SEER ratings for the same equipment due to revised testing methods. When comparing systems, it’s important to compare SEER2 to SEER2 — not older SEER numbers.
Minimum SEER2 Requirements in Wisconsin
Wisconsin falls under the Northern Region efficiency standards.
Current federal minimums for the Northern Region are:
Air Conditioners: 13.4 SEER2 (equivalent to 14 SEER under the previous system)
Heat Pumps: 14.3 SEER2Higher-efficiency systems exceed these minimums and may reduce long-term operating costs.
What Higher Efficiency Means for Your Home
A higher SEER2 rating generally means:
- Lower energy consumption
- Reduced utility costs
- Improved long-term performance
However, higher-efficiency systems may involve higher upfront costs. The right balance depends on your home, insulation levels, electrical capacity, and long-term plans.
Proper sizing and installation are just as important as efficiency rating.
What Higher Efficiency Means for Your Home
Higher-efficiency HVAC systems may qualify for incentives under IRA, HOMES, HEAR, or Focus on Energy programs, depending on eligibility and program guidelines.
