Packaged Units
Packaged systems (also called Packaged Air Conditioners, Packaged Gas Furnaces & Air Conditioners, Packaged Heat Pumps, and Packaged Hybrid Heat) combine all major components into one cabinet outside the home. They’re ideal where indoor space is tight, and can be mounted at grade or on the roof with supply/return ducting into the home.
Just like individual furnaces, air conditioners and heat pumps, these package units carry SEER/SEER2, EER/EER2, AFUE and HSPF/HSPF2 ratings. The higher the rating, the more energy efficient the unit is. The Department of Energy’s (DOE) new minimum efficiency standards vary by region, so your choice of package units will depend on where you live.
The DOE’s regional breakdown by state is as follows:
- North
- 14.0 SEER/13.4 SEER2
- 8.0 HSPF/6.7 HSPF2
- 80% AFUE
- Southeast
- 15.0 SEER/14.3 SEER2
- 8.0 HSPF/6.7 HSPF2
- 90% AFUE
- Southwest
- 15.0 SEER/14.3 SEER2
- 8.0 HSPF/6.7 HSPF2
- 90% AFUE

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, AFUE 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 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.
