Replacing furnace, need opinions on evaporator coil


This isn't exactly a DIY question, but I can't think of any other community with this expertise.

I am replacing my old furnace from the 80s through a contractor. I intend to get AC installed in the future so should I have the evaporator coil installed as well? Would it be easy to install one after the furnace has been installed?

I live in California, and I'm being quoted an extra chunk for the evaporator coil install.

You should only get the coil put in if you know exactly what a/c you want installed in the future, and only if u intend to do it 1 year or less after the furnace since models change.

The coil has to be properly matched to the outdoor unit. Size, seer rating, and manufacturer can change the coil required.

13 seer uses a smaller coil than 14+ for the same outdoor unit tonnage. 16 seer uses an even larger coil.

You get a cleaner install with the coil included since they can put it in before closing the plenum or it can be a cased coil perfectly matching the width of the furnace. When you add a/c after, they cut a hole to put the coil in and patch it with sheet metal.
