Portable a/c unit?

No it won't. But I guess that depends partly on your definition of "works fine".

It will cool ONLY the immediate area where the cold air is blowing......while making the rest of the interior space hotter.

See my previous post.

I bought a MH with w/d in it. Took it out as unnecessary for us. The mt space under the kitchen counter is perfect for a portable a/c. It has its own circuit, water drain and a hole in the sidewall with a dryer hood to the outside.
I've never needed to use it but it is perfect for an a/c.

We had to use a 10,000 BTU unit from Home Depot or Lowe's and it does a good job but as mentioned above, the heat from the hose puts a lot of heat back in the coach. The closer you can get to the exhaust window the better. We bought some fiberglass insulation with alum. backing and wrapped the entire thing which helped dramatically. The floor models do take up a lot of space but I don't have any window that would fit a window A/C unit. Do not bother with the units that do not use an exhaust hose as the others are trying to make the swamp cooler effect in your RV and it just doesn't cut it.

A Class A? I don't know of any units that could keep one cool. The problem is in the exhaust hose... they emit a LOT of heat, and you'll be fighting to keep that heat down while cooling everything else.

I use a 12,000 BTU Delonghi Pinguino I picked up at Sam's for about $300. I would imagine it would take two of these to cool a class A, as this is barely adequate in my 20 foot C on a hot day.

Thank you. I plan on using it as an additional unit along with the bedroom unit if it's feasible. Maybe use the portable in the living room area while running the bedroom unit. Are you saying the hose emits a lot of heat, or just the unit if you didn't use a hose? The heat from the vent hose was going to be another question.

The hose itself radiates heat, as its just a thin plastic flexible hose, similar to a dryer hose, only larger. The hot air running through it and out the window will heat the hose up. I wrap an old blanket around the hose to insulate it a bit, and in my C I can put it between the front seats, vent out the passenger window, and fold out the front bunk, draping more blankets off the bed to keep the heat in the cab area (venting that area with the wing windows).

It will work fine as a supplemental unit. In my case, however, I have no roof top unit, so its my only source of cooling the house when parked.

We have a window unit that we use in the back. $80 off Craigslist. The window unit and the front air conditioner together keep the whole RV ice cold even in the worst summer weather. It doesn't take up floor space and all the heat goes outside.

Seems like a lot of people don't understand this but.....a single hose unit is just a cruel joke.

The air that is heated in the unit and blown out through the hose has to come IN from somewhere. Stop and think about that for a minute.

When it is hot outside, then hot air is sucked in through small cracks and crevices all over the RV....or house if used in a house.
That air coming IN means that your over effective cooling can be pretty close to NILL. That is NOTHING.

If you really want to do this and want something that is really effective, get a double hose unit. Otherwise you will just be wasting your money. A single hose unit likely will spot cool one small area.....at the expense of making the whole rest of the interior less cool.

I have used a SPT heat pump/AC unit for several years. It is a single hose unit and uses less then 10 amps. The model I used is WA-1061H. It makes a great addition on a hot day and we have used it as a heat pump in temps just below zero. I used it as an add on to my roof top AC.

I can't find what you're describing, is it mounted on your roof?

Go to Amazon and put in SPT WA-1061H. It is a portable unit. All of the heat generated by the unit is vented to the outside.

Howdy!

During our stay in Florida last summer our AC could not keep up with the heat. We also purchase one from Sams Club. It worked well but as stated you have to vent them they produce a lot of heat.
