My whole condo complex has GE AJ...series wall air conditioners. As our forced air heaters are dying with no repair/replacement seemingly available, some owners had put in AJ units with heat pump feature. Apparently they no longer are made like that, just straight cool. Anyone have different info???

Our FAU are Suburban Dynaceil. I believe they went out of business shortly after selling Pardee Builders several hundred units! For at least 15 years we have been told that there are no parts...heat exchangers, control board, etc. available. Because of how they are installed...they are pancake units to fit in a shallow soffit...and direct horizontal flue and combustion intake.....there is no replacement available from anyone.

Any other ideas?
