Window A/C Units: Other install methods

So David has won the Air Conditioning "debate" so we will be getting one (and the generator that would be needed to operate it). We have decided to install ductwork down the center of the bus under the floor (it would run approximately down the center of the bus). The bus' original fan-forced hydronic heat exchanger that sits in the rear of the bus will be centered under the bus just behind the rear wheels. Along with a large 120v window air unit. They will share a plenum and all the duct work will be run under the floor with vents tucked up in the fronts of cabinets/walls. The Generator (looking at a 6000W genny from Home Depot) will be installed under the bus, hung off the "rails" that run the length of the bus between the rear bumper and the heat/air units. We will most likely have to remove the fuel tank (gravity feed fuel system) and set it next to the rear bumper and add a fuel filler. This generator seems to have an electric start panel that does not appear in the webpage description. We looked at this one in the Home Depot in Los Lunas but need to go back and study it a bit more before we buy. BTW, its rated at 79 DB. Loud but not horrible.

(the Handle folds down and we would remove it)

And then there is this one that is available online only.. same price more watts....

This was some great info on installing a window AC unit but one is thru the roof and the other is in the "basement". Makes you think...

Re: Window A/C Units: Other install methods

I looked at an old Avion trailer many years ago, it had what appeared to be a factory installed AC unit. It looked like it was a window unit mounted low (bad idea) in a wall near the center of the unit. Basically under a storage closet. The only thing visible from the outside was a nice looking grill.

Re: Window A/C Units: Other install methods

I think the duct will work, although I would do some planning for maybe a muffin fan at the outlet if needed just to help things along.

Re: Window A/C Units: Other install methods

Has anyone tried the indoor AC Units in their bus???????? My son is stationed at McCord AFB in Washington state......
This past summer it got really hot there. about 10 - 20 degrees above the norm of 70 - 80....No AC unit in government quarters (his anyway) I understand as they remodel they are adding AC units ...
The moral of the story is he purchased an indoor AC unit to cool his house. worked well but not great, he really needed two of the units . one not enough for the house.
Anyway they only need to but vented outside like the dryer vent. and of course dumping the water tank as it fills. Just wondering if these might work well in a bus?

Re: Window A/C Units: Other install methods

I've heard that they don't cool very well. No practical experience though.

Re: Window A/C Units: Other install methods

just make the ducts large enough. thats half the problem with conentional RV's is that the ducting is too small mostly due to the roof not having proper room.

Re: Window A/C Units: Other install methods

I have an indoor unit in my semi does ok up to about 85 deg after that if the sun's shining it doesn't do very well. Big problem there is no regulation concerning what they can advertise about the unit.

Re: Window A/C Units: Other install methods

I am considering installing a unit in my bus.
I looked at the closed article mentioned in a post here where the guy converted a window unit to a roof top unit.
I looked at his pictures and one thing I didn't see was the vent for the room air to be sucked into and then blown through the evaporator back into the room?
If this intake is in the same box shown in his picture wouldn't the evaporator just ice up on you?
I have also seen other posts where people have put the unit into a cabinet on top of the refer and vented the condenser through the window; BUT again I see where you would be pulling cool room air into the side vent and blowing it out through the condenser? Am I wrong?
I would think the vent to the outside would need to be in two parts; one for exhaust and one to pull outside air to blow back out through the condenser and not using your cool air inside to do that?

Re: Window A/C Units: Other install methods

Window A/C units ("Room Air conditioners) recycle interior air. They do not pull it in from outside. That big huge section under the part that is pushing out cold air is sucking the same air back into it. You need it to get air, whether is is sucking the in the immediate vicinity or pulling it, thru ducts and a plenum, from another part of the "house". Most folks will simply use the air in the immediate vicinity rather than building a duct systems to pull the air from another part of the "house". The window units are made for that... it's why they are called "room " air conditioners. The motor, etc, needs ambient air flow to dump the heat from all the cold air making components. Once you understand how an air conditioner works and how a window A/C unit works and that it only recycles the air, it becomes much easier to figure out how to adapt an A/C unit to fit your specific application. I'm not going thru this again, use the link. We had to explain to one of my daughters how an A/C unit works last night and why she couldn't just plug the window unit (we just bought it up in Albuquerque) in her bedroom with it sitting on a table in the middle of the room. And had to deal with the idiot boyfriend who thinks he knows everything (yet knows nothing) in the process..... heavy blunt object... shallow grave out in the desert... wishful thinking.

Thanks, John
Don't! If you tip an AC unit on it's side (or upside down) you have to wait 24 hours before you can run it after righting it. It's like a refrigerator. There is an UP on them. You can burn up the compressor. Just build a plenum and mount the front of the AC unit to it (section for cold air out and also a return air section). Plenums are easy. They are just junction boxes for routing the ductwork. We built the one for our Class C furnace from lightweight flashing (we just cut it with a pair of kitchen shears... the kind you use to cut up chicken). Just a metal box. Make sure you get the metal tape and tape up any place that air can seep out. Also keeps the bugs out.

Click on the thumbnail to see a bigger picture. If you look at the bottom of the picture, you can see the simple plenum that we built for the furnace. The air just blows down into the opening (see where the red electrical wire is) in the top of the box and the out to the ducts on the sides of the box. You can also see the shiny metal ductwork tape we used. This stuff sticks very well ... to anything it touches... including me.


Very simple to make.
