I have a all the Hvac tools and the R407c to put back in it. but Just going to see how much hassle all of this is. Also with this being Winter its not enough ambiant heat outside to really get the moisture out. Edit. just realized the Compressor has had a hole drilled in it as well, so i guess i will end this thread and probably scrap everything but the generator. Thanks for all the replys

Well you should change the filter dryer for sure if it lost charge, but the hole in the compressor could be patch welded...pull a vacuum on it and see what you have, if it holds...then put a Nitrogen charge in and see if it holds.....then, then start to think about putting some 407c in...

So This Whole thing has kinda gone south. After finding the hole in the Condenser Unit i was informed by my coworkers who are HVAC TEch that this unit is not going to be worth fixing due to Moisture from being open to the atmosphere. They said i could charge it and probably run it for a while but that oil would be contaminated with water and create acid. so at this point the Generator may come off the trailer and scrap the rest. We shall see what i decide to do.

Did these HVAC Techs then offer to than the whole sad thing off your hands for trivial payment?

Any creative advice for repair of broken heater elements? Several broken from the outlet cover flapping in the wind.

So I bought 3 units with the same issue. They actually drill a hole in the radiator coil for the auxiliary coolant heat in front of the condenser. This drains all the coolant out of the system. I actually used solder for that fix because its not pressured like an AC system. They drilled a hole in the same area on all mine. I replaced the compressor on the 1st unit but the rest I welded them up. All have run for over a year and they have around 500-1000 hours on them. Dont give up.

do you have a nsn and any experience if you buy them from GP if they drill holes in all the HVAC units before sale

I have maybe 20+ Nordic air ECUs and none of them have been drilled like yours have. Most have been drained and some had their service ports left open. I just vac them out and fill, and they function 75% of the time. Meaning 1 of 4 have some sort of issue that's not worth fixing. Mine are r22 but the newer ones are 407c.
