Mid June Florida Pan handle and main room unit not cooling

[FajahRogers]

My 355th main unit not cooling, blowing but not cool air, kinda wrecked a week long vacation in Carrabelle Fl.

There was a guy in the park that told me his main unit was never any good and GD sent him a new one and he paid to have it installed. I would love that deal.

Two things.

What is the refrigerant and are there ports on the unit for adding more?
How hard is it to add 3rd unit, there is a circuit breaker and it has a multi zone thermostat? my closest dealer and the one I got the unit from is Dixie RV and they are a rip off so I need an alternative ( I would burn it to the ground before I would let then work on it again (or not work on it is more likely).

Thanks,

I believe most RV AC units are sealed, so you'd have to install a port to add refrigerant. I've heard the hardest part of adding another unit is getting it to the roof

Ok,,,did all my troubleshooting and it is official, the refrigerant is low or gone. Gonna get piercing service port tomorrow and charge up the system. Everything in the unit looks awesome and like brand new, just a early failure and leak somewhere. I will recharge and see if it buys me 2.5 years, that is how long it took from new till now.

Dometic should have a kit, they are impossible, at least for me, to get in touch with.

I will keep anyone that is interested in the post up to date.
