Air Conditioners

Compare cooling-efficiency ratings, understand why minimum standards can vary by region, and discuss air-conditioner options for your home.

Minimum air-conditioner efficiency standards can differ by U.S. region and may change over time. Confirm the current requirements for your location and review the proposed system’s published specifications before choosing equipment.

Understanding the ratings

SEER2 is a Department of Energy testing update intended to better reflect typical operating conditions than the earlier SEER method. SEER/SEER2 and EER/EER2 can help compare efficiency, but compare like-for-like ratings. EER2 measures performance at a 95°F outdoor condition; SEER2 reflects cooling across a season and a range of conditions.

• EER2 measures efficiency at a peak cooling temperature of 95°F.
• SEER2 measures efficiency across a cooling season; the published guide describes a test temperature range of 65°F to 104°F.
