Well after all that I went and got some 10/2 Romex. Only cost me 12 bucks. Gonna wire it up today.

Just thinking along the lines again of "overkill is under rated".

Do you see there being any problem with it? AC is now up and running.

When we install mini splits we run 12-2 for 18000btu or less and 10-2 for 18k+... This is due to the amperage spike every time the compressor kicks on. You 15amp circuit may pull 70 amps or more when the compressor kick on.... It is also nice to install a quick pull disconnect in the circuit somewhere, oh and rain tight conduit.

I do this stuff every day of the week so if you have any other questions feel free to ask.

Yeah, I made sure I had good contact.

Next project haha, got to find a good exhaust fan my barn. I mounted the compressor inside so it's gonna get hot come summer time.

That will be a new thread coming soon.

Thanks again HITH.

Thanks OhighO, any advice for folks who mount their compressors inside their barn?

Haha... You could build a fan shroud that sucks the hot air expelled from the condensing unit"outdoor part" and duct it outside. You are going to lose effeciency very quickly when it gets hot outside... Or build a room around the condensing unit and move a shit load of air through it. Your best option is definitely to move it outside though... We mostly sell Mitsubishi s and they are so quiet you can't even hear them run when standing next to it.
If you decide to go this route I could draw a wirin diagram that would kick on the fans only when the unit is running.

Interesting idea. If I built a 4x4x8 room around it how much cfm you think it would take to keep it at or slightly above ambient?
