I recently replaced my gas heat pump with an electric heat pump, and the installers told me that if I wanted the warranty, they had to replace the whole system including the air conditioner with parts they supplied. Now, I am left with a working central air conditioning unit to try to sell and no information about it. I don't have any of the manuals for it or even model information. It looks very similar to the Coleman Comforteer Series. Does anyone have any information about where a model number or name would be located? Does anyone know approximately what the just the unit would be worth?

There should be a model tag with a bunch of information on it attached to the unit. It was there when it left the factory and still should be there unless someone took it off. Other than that I would have no idea what you are talking about.
