Air Conditioners
Air conditioners may look similar, but their Seasonal Energy Efficiency Rating (SEER/SEER2 and EER/EER2) can vary widely. For air conditioners, the Department of Energy’s (DOE) new minimum efficiency standards vary by region, so your choice of AC units will depend on where you live.
The DOE’s regional breakdown by state is as follows:
- North
- 14.0 SEER/ 13.4 SEER2
- Southeast
- 15.0 SEER/ 14.3 SEER2
- 12.2 EER/11.7 EER2
- Southwest
- 15.0 SEER/ 14.3 SEER2
- 12.2 EER/11.7 EER2
SEER Versus SEER2
SEER2 is an updated rating standard introduced by the DOE. SEER2 standards are intended to provide a better gauge of typical home operating conditions whereas the older SEER rating utilized very precise protocols to determine ratings in ideal conditions. SEER2 standards include updated testing means that give a better indication of how a unit will operate in the real world.
Much like miles-per-gallon for a car, SEER/SEER2 and EER/EER2 offer an easy way to compare efficiencies of different products – the higher the rating, the more efficient the unit. Just be sure you are comparing either SEER vs SEER or SEER2 vs SEER2 (same for EER/EER2).
EER2 Versus SEER2
EER2 and SEER2 both evaluate an air conditioner’s energy efficiency, but they’re concerned with 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.
Colonial Heating & Air Inc Can Help You Choose
We currently offer a line of air conditioners that meet the local minimum rating and go all the way up to a 24 SEER2. Depending on your average usage, higher SEER2/EER2 air conditioners can significantly reduce your electric bill.
Additionally, we offer many air conditioners that have advanced features, such as 2-stage compressors and variable speed fan operation. These features not only improve the comfort level of your home but can provide additional energy savings as well. Call us now at 770-922-6506.
