View Full Version : How Do I Add Rear Air Conditioning?

I have a 2006 Sprinter 3500 that has been converted for video production use. We currently have a roof a/c unit but it pulls too much power to run when the rest of the on-board computers and equipment are running. I have considered separating its power input but that brings up other problems. I know that there is a rear air conditioner option but I have no idea how to go about finding one and an installer. Can anyone offer any suggestions. Thank you.

Keep in mind that running your Sprinter at idle for long periods of time will clog up your EGR valve, so you don't want to drive the rear AC off of that unless its used only while driving.

I suggest you consider adding a generator rig to your vehicle. The 6000 watt units are probably at the minimum of what you should consider (Honda makes a very reliable unit). Then keep your roof-top unit.

Which A/C unit do you have? You might look at the Coleman Mach 3 PS as it draws much less power than similar BTU models or just get a bigger generator. Both options are probably cheaper than retrofitting the factory rear A/C plus you save the fuel and engine wear as a bonus.

you could build a red neck ac unit like mine.... I made this in just a couple hours. uses ice, water and ice packs.

Look at thread http://sprinter-source.com/forum/showthread.php?t=12571 or http://www.proairllc.com/rear_mounted_evaporators.html .

However, note that they are a serious current draw which could still be a problem at idle. Since you already have a 110 A/C, I'd consider a EU2000i for use when parked- which I have as well for use with a 110 portable A/C routed through the floor.

Does this actually work? Do you have instructions on how to build? Does anyone?

Thanks

Might look into one of those room-sized roll-around ACs, with a window vent hose. You could make an adapter for a front window, or hard-cut a vent in the side. They do require a bit of a venting for air inflo (cracked window), but they're not crazy expensive = about $300-400. If you have a lot of equipment heat gain, they may not be big enough. Not a huge current suck either, I think right around 15amps (1800w)

If you're really hard core, you could look into a semi-truck style APU with AC, Gen and Heat capabilities. They will require some custom mounting / install solution tho. I've thought one would be cool, except for the $$ and the space needed.

I bought my 2003 Sprinter used and it had a RAC (Rifle Air Conditioning) rear ac unit already installed. The ac unit is tied in to the main ac and works very well. The paper work I have on it shows that mine is System 29 Tie In and was installed in 2003. I do not see that system listed on the site.

Here is a link to the manufacturers site. http://www.rifledair.com/

I've thought about one of those in-room roll around AC units too, when I'm hooked up to city power.
But I thought the vent to outside was actually warm air exhaust from the cooling unit, not air in-take.

My van has what looks like an aftermarket under dash unit that you could buy thru JC Whitney.
They took some angle iron and mounted it to the roof just behind the front seats.
Looks like they just plumbed it off of the existing VAN AC.
Looks like there is some sort of adapter manifold under the hood.
Didn't work when I was thinking about buying it.
Had to be repaired for condition of sale
they fixed it, but it don't work now and I have no AC.

Of course in Washington State, people don't see the necessity for AC
Try Florida. Haven’t pursued it yet. Too many other projects.
I’m wondering if the original AC compressor can handle 2 cooling units.

I think I have a leak, thinking about calling the used car dealer to see where he took it
as I have no books, no name plates, nothing to figure out what exactely I have.
Try to find out what they did to it to make it work.
Or just adding some leak fix?????
any ideas?
