I found a guy selling Coleman/York 4 ton package for $XXXXX in the box with 5 year warranty for parts and the condenser, 10 year for furnace.
He is selling them online and will personally deliver to my area.
I am new to this and not sure if i shoud trust him, or this brand.
I would have to have someone else install it. Any advice on whether this is a good idea or not?
