Question on "belly type" air conditioner

[larry2c]

I am trying to prepare my MIL's 2002 Alfa Gold 5th wheel for sale (she's widowed now and living in the 5er is becoming an issue). This model of 5er has a belly type AC unit and I was wondering if anyone has any experience with those type units. We're still trying to find the manuals on all the trailer equipment but until we find them I'm asking questions of the RV community.

Does this type of AC allow you to recharge the refrigerant? The unit still works but the cooling is really weak and it seems like after 17 years on the road a recharge might be in order. Anyone have any thoughts on this?

Thanks!

Thanks for that info Doug. I know my MIL looked into getting it worked on a couple years ago and the guy she talked to wanted $1500 just to diagnose what might be wrong.

Just one more thing to check off the fix it or forget it list (check goes to forget it)

I have yet to see a RVP basement unit on a slide out track. ALL I have seen you have to drop them to do some work. Some you can get to the controls and capacitors without dropping them. NONE will have a charge port. They are sealed just like roof top units. Our shop also will not work on them. Most customers do not like to pay the extra labor that is involved, so we decline to work on them. Doug

This is my MIL rig - she is 85 years old and will be moving into a senior living facility. The rig is her last asset so we want to get as much as we can so she will actually have a few dollars in the bank . Every little bit helps...

So I have done some searches and I can't say I've found much technical info on the specific AC unit she has. However, it sounds like the basement AC units in an Alfa are NOT on a slide out rack and you actually have to put the trailer up on a rack to raise it high enough to lower the AC unit out where you can work on it. If that's the case then this is probably a nonstarter for my working on it. 😞

Clean the condenser fins then let it run awhile & see.
If it actually needs refrigerant , you have a leak somewhere. Any hvac tech can add a " piercing valve " to check pressures, find and fix leak.

They are called basement air conditioners, and typically do not have provisions for adding refrigerant, but they hold so little, if they leak they are usually empty.
A good cleaning would likely do the trick.
