Power for second ac unit

[david-steph2018]

Thank you for the replies. I tried the NCVT Monday and wasn't able to pick up voltage through the wall or ceiling. Got to thinking about what exactly they mean by front vs rear AC. I had been thinking of the AC unit in my living room/kitchen as the front unit, and the rear would mean the garage. Nope. Found the front AC wire in the front bedroom vent, so the rear is the living room/kitchen unit. So, good input, david-steph2018! By the way, the front vent has a blank termination (basically looks like a receptacle with no outlet). This makes it super apparent where the AC pre-wiring is, and it is live with the F AC breaker on. Unfortunately, it does me no good. The bedroom is cooled just fine with existing AC unit in the living area, while my garage does not get sufficient cooling through the one ceiling vent. I use it as my office when working remotely, and it got pretty hot in there last summer. Had to use a fan blowing from the living area into the garage to help, but it simply needs it's own AC unit.

Now that I know this, my plan is to fish a wire from the garage cabinet receptacle up through the ceiling to the garage vent and add a 13K BTU unit. I have fairly decent access in the cabinet, and the speaker opening in the ceiling. The 13K unit should be fine on the 15 amp circuit, as the only other things I'll have plugged in is my laptop and monitors.

Can you run a wire from the breaker panel thru the underbelly to the cabinet. Then go like your plan.
If you do as you plan, consider adding a soft start to the AC unit, it may help you with starting current if you have more plugged in to the circuit.

I considered going under, but have no access from the underbelly to the ceiling, without significantly tearing open the RV. I will look into the soft start.

Have you thought about one of the small, roll-around, portable AC units for your garage? These use a flex hose (like a dryer exhaust hose) that attaches to a universal window adapter to remove the hot exhaust air outside.

Yes, thanks, that's an option if I can't fish the wire, or encounter some other unknown surprise I haven't come across yet. I'd rather not have something taking up floor space though.
