I live in an upper floor condo a packaged unit Magic Chef about 20 years old. Because of space considerations ( the unit basically sits in its own closet ) the recommended replace is also a Magic Chef, the CPG1838-B.

The AFUE rating is on CPG1838-B is about 80%. Would anyone know of any Energy Star equivalent that could be used instead of this model. The air conditioner is part of the package and its SEER is rated at less than 11. I haven't been able to find any packaged units that don't require the unit to sit outdoors.

Any help would be much appreciated!
