Keeping inside of bus cool

Is there an air conditioning unit that doesn't require the typical full A/C system . Looking for a way to keep the bus cool while working inside during the upcoming heated days in the Houston area. Don't think a fans gonna cut it. Anything 120v out there?

A couple of decent window units would be the easiest temporary arrangement.

I'd suggest a swamp-cooler, but the humidity is too high in Houston and they require a well-insulated space to work effectively.

The ducting would need to be changed and most window AC units are taller than roof top units and are likely to be scraped off in the first gas station. I'd recommend a sweat band and going nekked. Jack

Most RV rooftop units have that type mount. They are pricier than the window units.

Just google "portable ac unit". They work like a window unit without the hassle of installation. They are reasonably priced and fairly effective.

The two hose portable units are more efficient than 1 and if you insulate the exhaust hose, even more so.

A roll-around unit that uses a 4" vent hose to direct hot air out...

First of all, howdy from just barely south of you on I-45 in League City! So when it comes to coastal Texas heat and humidity, I know exactly what you are talking about...

If you are just setting up AC so you can work on the bus in the Houston summer, and of course this is going to depend on #1. How big the bus is, and #2. Are you keeping any of the windows?

How big will determine how much AC you will need, windows will determine where you can put it.

Portable ACs exist, I have one in my garage workshop. It's better than nothing, but not by much. Although they DO allow you to vent in a much more flexible way. Check the reviews on the portable units though. For the most part, and I am sure there has GOT to be one that isn't like this, but all of them I have seen are of incredibly poor build quality, leak condensation like crazy, and, well just don't cool well when they are working.

If you have to go rooftop, just go ahead and fork over the $$ for rooftop RV AC units and install / run them as you work. You are going to need them anyway if you are going to be staying anywhere near Houston metro from April through November...
