Air Conditioners

While air conditioners may appear similar, their Seasonal Energy Efficiency Ratings (SEER2) and Energy Efficiency Ratio (EER2) are crucial factors that can significantly differ. These ratings, set by the Department of Energy (DOE), establish the minimum efficiency standards for air conditioners, which vary by region. Therefore, where you reside will influence your AC unit choice.

The DOE’s regional efficiency minimum breakdown by state is as follows:

• North
  • 13.4 SEER2
• Southeast
  • <45K/14.3 SEER2
  • >45K/13.8 SEER2
• Southwest
  • <45K/14.3 SEER2/11.7 EER2
  • >45K/13.8 SEER2/11.2 EER2

EverRest Extreme Comfort Can Help You Choose

EverRest brand air conditioners currently offer a range of models meeting local minimum ratings, with options ranging up to a 22.5 SEER2. Air conditioners with higher SEER2/EER2 ratings may reduce your electric bill, depending on your average usage.

Get ready to experience a new level of comfort with our range of feature-rich air conditioners. These include high-efficiency inverter- and 2-stage compressors, variable-speed fan operation, and advanced connected control systems. Your local EverRest dealer can design a system with these features that enhance your home's comfort and maximize energy savings.

SEER Versus SEER2

SEER2 is not just a random number. It is an updated rating standard introduced by the DOE, designed to assess typical home operating conditions more accurately than the older SEER rating standards. The SEER2 standards incorporate updated testing procedures, providing a more realistic indication of how a unit operates in real-world scenarios.

Like miles-per-gallon for a car, SEER2 and EER2 provide a simple method to compare the efficiencies of various products – the higher the rating, the more efficient the unit.

EER2 Versus SEER2

EER2 and SEER2 both evaluate an air conditioner’s energy efficiency, but they apply to two different types of temperature conditions:

• EER2 measures an air conditioner’s efficiency at the peak cooling temperature of 95°F.
• SEER2 measures an air conditioner’s efficiency throughout an entire cooling season, with temperatures ranging from 65°F to 104°F.
