I'm installing a small minisplit for my garage. The garage is part of the house (front right corner of the house) and I have to put the minisplit condenser in the back of the house.
My breaker panel is outside at the front right corner of the house. If I go straight through the back of the panel, I'm in the garage. I need to get power to the rear right corner of the house.
What I've come up with for options is the following..run pipe from the bottom of the panel down to the area where the slab and stucco meet. It varies between 6 and 8" off the ground. Then follow that down the side of the house to the back, make the turn to the back and run up to a disconnect where I need it. I would pull individual wires. Is there any issues running pipe like that?
The other option is to go into the garage, pipe it to where the lineset will be going up into the space between the first and second floor and follow the lineset out the back of the house. but this means the wire would partially be in pipe and partially be in a rafter space. That means I can't use individual wires. I'd have even more pipe in my finished garage. I'm also unclear the proper way to exit the building. When I exit I have to pipe it to the disconnect correct?
I'm in Phoenix, so no issues with snow. Thanks.

Since you are running your lineset inside run your power along with the line set. Conduit up the wall from the panel enter the house and change over to NM cable. Or run n conduit inside your choice. Run to the back wall. Most Electrician’s will use an LB conduit body to enter the home (and or exit). Run down to your disconnect with conduit.
To me that sounds like the cleanest install but you can run your conduit at the foundation. There is less chance of the conduit getting damaged up and inside schedule 40 pvc conduit inside would not be that hard to put in. Schedule 80 will be needed at the foundation level of using pvc. EMT can be used in both locations also. I prefer emt over pvc I think it is easier for sizes under 1” but that’s just an opinion many people use pvc. Note; You will probably need an expansion joint with pvc outside along the foundation.
