If you have some carpentry skills it generally isn't that hard to resize your opening, but it's a chore. You can probably find something modern and efficient that will blow freezing cold air and fit easily into the existing opening with minimal alteration. You're definitely going to get spendy if you want to retrofit an old house with central A/C. You could blow through $10,000 pretty easily depending on the house. 16,276 posts, read 44,896,608 times Originally Posted by Coldjensens yes - a window unit fit into the wall. so, this is something you think i can just pull out of the wall and put a new one in? i don't feel as though this is something i can do myself....i'm not saying i'm not handy, i just thought that since the unit must vent to the outside, there would be some sort of sealing involved?

If you want some free advice on how to hack-up your house you could try to post a picture and I'm sure you will receive lots of it.

I have no idea why, they look the same to me. At any rate I have decided that when the unit dies out I am going to fill the hole, possibly with a window and install a mini-split/heatpump system in the room.
