Portable A/C

The front A/C in my 95' Monaco Windsor has gone out and we are schedules to go to Va. for my grandsons college graduation. I want to put a portable 110 A/C unit and run it using the generator. I don't have time to have the A/c fixed in the motor home. Does anyone see a problem in doing this?

A decent portable A/C will cost about $300.


A replacement rooftop A/C will cost from about $400 on up.

I know time is an issue, but I'm not sure a single trip is worth the portable A/C.

We use a portable aircon in our RV's garage (Class A Toy Hauler) because the factory set-up couldn't keep up in the southwestern heat.

We use the portable in the studs and stucco too, so it was not a wasted purchase like if the intension is to repair a rooftop.

The only issue is the warm air exhaust needs to exit the RV. In our portable that is a single dryer duct style tube. And some portables use 2 ducts for compressor in and out to not waste the aircon on the compressor. You need to figure out how the duct will exit the RV.

Best luck

I used portable AC unit to supplement the basement air in our RV. It worked well. The draw back is it is kind of large and of a pain to move around or in and out of the RV. Setting it up to exhaust out a window was not a problem. I've since repaired the basement air and added a roof AC so don't carry it in the RV but do use it at home as needed. Bottom line it is not a problem as far as I can tell.

Thanks for all the quick replies. I already have a portable A/C unit so I won't have to purchase one. I will get in in the motorhome today and give it a try.
Again, thanks for all the advice. This site is worth it's weight in gold for a newbie RV owner like myself.
