My 2019 Bighorn had the same problem. Took about 30mins to start cooling. Dealer replaced the "H" valve. they also said the factory had put in the wrong freon which screwed up their evacuator system. when I finally got my truck back the A/C works good.I had a 2017 Bighorn for about a year & a half. I took it to that dealer to have the A/C checked shortly after buying it. The dealer said everything checked out & the temps were within normal operating range. After it was totaled back in January 2019, I purchased a 2019 Bighorn. IMHO, it takes my 2019 a little longer to cool, but it does the job. I haven't gotten cold air out of either one of them.
Not to derail this subject, but when I bought my 2019 back in February, I did not realize the trim levels had been changed. It was a trim level one, just like my 2017, but some things were not the same. My wife truly misses the heated seats I had in my 2017.The cool seats are “to die for”. Best option every........
MY "Silver" 15 Laramie was excellent and would freeze me out of the truck. 19 is no where near as cold.... its also "black" and has the full length sunroof that probably doesn't help.For the guys who've had previous gen rams, does the a/c in the 2019 work better? My 08 and 15 both didn't quite cool as cold as I would like.
It is a new system they started to introduce in 2014 but not all Rams. I have a 16 3500 with the old system and I can hang meat that it can get that cold. But I have two friends that have this new 1234yf system. One says his works fine and the other has had it in the shop twice and still not happy. Current prices for this new refrigerant are around $120 a pound and of course the dealers are the only ones that have itFor the guys who've had previous gen rams, does the a/c in the 2019 work better?

All well and good, but nobody should have to "hack" a brand new truckHere is the link to the AC fix https://5thgenrams.com/community/threads/air-conditioning-hack.10150/
Yeah, I don't think anyone would argue that; I'm just trying to post information to help someone. I guarantee next summer a crapload of guys with 2019 and 20's will be complaining about how hot their AC is and they will try the AC Hack. I did, because I don't want any dealership idiots tearing into my dash (because that's where the problem is, behind the dash where the mixing door is) or anywhere else on my truck and then returning it to me without it working properly. This is a manufacture screw-up and sometimes you have to take matters into your own hands. Oh, and if you think FCA is going to come out with a fix, be ready to wait forever. Reason being, for this to become a real issue, the AC has to show it can't keep up with 50% of what the ambient temp is outside. Meaning, if it's 100 degrees out, the AC only has to blow 50 degree air at the vents with the truck running down the freeway (that's their spec). With the current issue, the AC systems can do that, but that is not good enough as an owner. Getting in a hot truck and blowing 50 degree air is lame as hell. It takes like 45 minutes to cool the cab and even then it's barely keeping up.All well and good, but nobody should have to "hack" a brand new truck
