Duct Free Systems
Duct free heating and cooling systems make your home's individual rooms or other small spaces more comfortable. Remember, just like whole-home systems, the higher the SEER/SEER2 and HSPF/HSPF2 ratings, the more efficient they will be.
The DOE’s regional breakdown by state is as follows:
- North
- 14.0 SEER/ 13.4 SEER2
- 8.8 HSPF/7.5 HSPF2
- Southeast
- 15.0 SEER/ 14.3 SEER2
- 12.2 EER/11.7 EER2
- 8.8 HSPF/7.5 HSPF2
- Southwest
- 15.0 SEER/ 14.3 SEER2
- 12.2 EER/11.7 EER2
- 8.8 HSPF/7.5 HSPF2

SEER/SEER2 And HSPF/HSPF2
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.
HSPF2 is the newest type of rating system that expands on the basic HSPF scale.
Much like miles-per-gallon for a car, SEER/SEER2, EER/EER2 and HSPF/HSPF2 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 and HSPF/HSPF2).
EER2 vs. 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.
