i was thinking about removing all my ac underdash components seeing as i have no care for putting ac back in my car in the future...so what exactly can be removed and would it in anyway affect my heating or air flow??

 

Their is a big black box behind the glove box that is AC related and can go if you buy the AC replacement duct.

 

You can remove all of the a/c components and you heat will not be affected. If you are not sure if the a/c blower is the same as the heat blower, disconnect it and try the heat first, before you remove it.
From underhood you can remove the dryer, the compressor, the condenser, all of the lines and the fan.

 

This item under your dash is called the evaporator, If you would like to remove that you would need the replacement piece that comes in cars that are not equiped with A/C. Go to your local junkyard and it can come out of any 88-91 civic that doesn't have a/c it should be $5-10.... these pieces transfer the air from the blower motor to the vent system. If your in the bay area, my buddy might still have his, I helped him put a/c in his car a few weeks ago.
