Went through the same with mine, overcharged. https://www.trifive.com/forums/showthread.php?t=157296

Glad it works a little better for ya now!!

It was DEFINITELY over charged, and in all reality it needs to be re-evacuated and start all over again, but this time don't let your A/C guy go buy what V.A. recommends to fill your system with. The instructions on the unit i put in the more door according to V.A required 36oz, and twice i filled they system with exactly 36oz, and both times it was over charged and the A/C pump would just cycle off and on once it built up to much head pressure just like yours was doing at the NATS.

So the third time I ONLY WENT BUY THE ambient temperature (the higher the ambient temps, the more low & high pressure you are going to expect and read on the gauges) and the high & low pressure readings, and it only needed 24oz and maybe 3 or 4 kisses from the third can, and it has worked GREAT ever since. I really don't under stand how they can give you a set amount of freon to put in when the size of the condenser and how long or short you A/C lines turn out to be dictate how much Freon your system needs.

And on top of that the R-134a is SOOOO much more finicky compared to the old school R-12. The R-134a does NOT LIKE TO BE OVER CHARGED.

I am BY NO MEANS a A/C expert, and i had ALLOT of help from wagzilla to help teach me what the heck i was doing and to figure out the system in the more door, but once i figured it out, IT IS NOT ROCKET SCIENCE

Love your Nomad btw ` John
Thanks John!!!

Congrats on your new 57, and welcome to .

If you have a center console, you might want to look at Vintage Airs complete unit that goes under the passenger side. I installed one in the wife's 57 more door. Pretty good set up, the heat will FLAT run out of the car, and the A/C keeps the entire car comfortable.

The complete unit comes with 4 vents, one for each kick panel, and then 2 you can sink into the center console like i did.

You will be dissapointed with a under-dash unit on the passnger side. It takes a car's air conditioner a long time to cool the whole interior. The cold air blowing on you body is what makes it feel cool. You will get very little cold air in the drivers seat, from a under-dash unit.
I originally installed a small universal unit in my 57. The air at the vent was 34degrees, but there wasn't enough volumn or force to feel it sitting in the seats. I have since replaced it with a tri-5 in-dash unit.

I agree with you 100% on that, but.on the bright side, I think the passenger would be all but freezing

I am even worried that the under the dash unit, or even a full fledged unit for that fact will not keep the Nomad cool enough since there is SO MUCH SPACE you are trying to keep cool in a wagon.

If this does turn out to be the case, I will be going to my upholstery shop, and see what kind of particion he can make me to either put behind the back seat, or the back of the front seat to try and keep the cool air up front. But then that opens up another can of worms trying to see out the rear of the Nomad and using the rear view mirror. The Nomad only has a side mirror on the drivers door, then I woukd have to add one to the passenger side door which I really do not want to do.

I have a friend that uses a clear shower curtain behind the front seat of his Nomad, when he travels.

Here's thinking outside the box, how about a half partition behind the drivers seat with an electric window like they have on limousines, now that would be different.

Thanks! That set up looks a lot like mine and should work really well.

No worries!!

When we drove the 4dr to the NATS in 2015 for the Inaugural show, it was SOOOOO humid, we had condensation coming out if all 4 A/C vents
