I know this site says 'DIY', but if this question belongs somewhere else, let me know which site is appropriate for this question. Thank you.
At the beginning of this month, I had a Coleman air conditioner installed and connected to the bottom of the furnace through some foam-covered pipe or coil. Also, I am totally blind. So, although I can feel some of the things that are obvious, some of the stuff, like the boxes on the side of the wall, I am not familiar with. What are these boxes used for? Can you open or lift the cover on each of them? Also, is my air conditioner considered a package system, where the compressor, condenser, and evaporator are all stationed outside, or is it a split system, where only the compressor and condenser are outside, and the evaporator is inside the furnace? Here's a video I took. Let me know if it is clear enough. If not, I'll take another one, and I'll try to include another one of the furnace.
