How do I cut vinyl siding for a through-the-wall air conditioner?
I’ve read some answers concerning outlets, etc. However, I am worried about possible leaking if I don’t do this right. I’m finishing a bonus room and have bought a ptac unit (think hotel air conditioner). It requires mounting through the wall. I can make the header and the hole on the inside, but I’ve never done anything like this through vinyl siding. Any suggestions?
It’s easier (and looks better) if you carefully remove the siding, cut your hole, then reinstall the siding. If your careful, you won’t need to buy any new siding.
* You will need to buy some “j-channel” to go arount the hole first. Caulk at least the top piece of j-channel. This will prevent leaks.
