Can I use my existing 3 ton evaporator coil and furnace?
You are able to do so as long as the tonnage stays the same and the same refrigerant is being used. However, you are not able to swap out a Goodman condenser with a MRCOOL condenser. MRCOOL cannot work with existing furnaces and coils; you would need to do a full system swap and get the MRCOOL air handler as well. Their air handler has an integrated coil inside as well as a blower motor, which requires a MRCOOL condenser to be matched with it.
