Triton V-10 Air Conditionning Recharge

So, the dash air on my 99 Tropical is pretty weak. It does cool a little which convinces me somewhat that the coolant has slowly leaked out over the years but that the system doesn't have a major failure in the seals so I am considering trying to do a recharge.

Problem 1. I'm not entirely sure what kind of refrigerant is in the system. I am in Canada and we banned Freon on here years ago. Can't even buy it if I wanted to. I don't know what the status was in the US and particularly for California were this unit was assembled. I assume that the chassis had to meet California standards which are probably tighter than a lot of states but some insight here would be helpful.

If anybody had done this job on their own rig, if you have any tips you can share....

A 1999 should have R-134a. Now a word of caution....handling a high pressure gas can be dangerous and if you do not charge it properly, you can wind up costing you much more than having a professional check the systems and recharge it.

I would not recommend a recharge until you have done a through leak check on the units. For a time, the manufacturers were using a evaporator with aluminum fins and tubes. They were prone to leak after about 5 years due to pin hole leaks developing in the tubes. There is no patch other than replacing the coil.

The Dash air on my 2002 National Dolphin was weak to say the least. Last year I did the "recharge do it yourselfer"..

It worked for a day or two...

Last weekend I brought it to a local shop. They pressure tested it, found a leak, fixed it, recharged it...

I do "everything" on my coach, but the AC system trouble shooting was above and beyond my doings...

Total cost $250.00

Small price to pay for driving comfort...

Thanks for the suggestions. I have been debating whether I wanted to take the chance on this. I think you may have convinced me not to. In that vein, can anybody recommend a shop that will do the air in NW Washington State.
