I would not run the A/C for love nor money plugged in to a "regular" house outlet.
Forget arguments. Ask an electrician. A professional. Telephone and ask how much it would cost for a tech to come to your house and give you an estimate of what you will need. I don't ask my barber how to do a valve job.
I HAD a friend throw a fit trying to prove a point about medical advice (his insistence would have been DEADLY wrong for me) and when he started to get insulting about it he is now a once-upon-a-time friend.
I do not need egotistical knotheads trying to bully me into doing things their way. I try to not actually fuel a feud. I smile and say "That's Nice!", ignore them and then mentally strike their position down a notch or two. Some facts and subjects I have experience with. When I am in uncharted waters I ask a range of professionals. If there is general agreement then the correct answer is there.
