Understanding Efficiency Ratings: SEER vs. SEER2 and EER vs. EER2

Minimum SEER Efficiency Ratings

At Krane Heating & Cooling, we understand the importance of selecting the right air conditioner for your home. The energy efficiency of air conditioners is quantified using ratings like SEER (Seasonal Energy Efficiency Rating), SEER2, EER (Energy Efficiency Ratio), and EER2. These ratings help you gauge how much bang you’re getting for your buck in terms of energy usage.

Understanding Efficiency Ratings: SEER vs. SEER2 and EER vs. EER2

  • SEER and SEER2: These ratings measure the energy efficiency of air conditioners over an entire cooling season. SEER2 is a newer standard that aims to provide a more accurate reflection of typical home operating conditions compared to the original SEER, which was based on ideal conditions.
  • EER and EER2: These ratings evaluate the efficiency of air conditioners at a single, high-temperature point (95°F for EER2). EER2 is useful for understanding how an air conditioner performs during the hottest days of the year.

The Department of Energy (DOE) has set minimum efficiency standards that vary depending on your geographical location:

  • North: Minimum 14.0 SEER / 13.4 SEER2
  • Southeast and Southwest: Minimum 15.0 SEER / 14.3 SEER2, and 12.2 EER / 11.7 EER2
