Refrigerant
What type of refrigerant does my AC unit use. Last two times we used it it would ice over and once it thawed it would be fine. A friend of mine says it's probably low on Freon and he was asking me ...

Hi,
The 1993 Factory installed air conditioner would have used R-22. If it was replaced after about 2005, then you might have R-410.
My guess is that it will be R-22.
Why does this guy have a problem bringing along two tanks of freon?
Anyway to answer all those who have been told "It can't be recharged" - I have recharged mine, and it works fine. Yes I installed a port. I have installed ports on window A/C units too. It was more for in-house work, where I was not billing by the hour, but rather spending $40 to save replacing a $650 air conditioner right away. If I had to bill for this job at $75 an hour, the cost would have been more than the $400 value of the air conditioner.
And my work was getting a $200 rebate from the electric company for each through the wall air conditioner with electric heat replaced with a R-410 heat pump that will run at 20F outside temp in the heat pump mode, until the outdoor coil trips a thermostat, that will shut off the compressor and turn on it's electric back up heater.
Good luck with your repair. Hopefully it will run for another 4-5 years before needing to be recharged again. At that time, it would only take a hour to recharge due to having a freon port already installed.

Refrigeration techs do not come cheap and GOOD refrigeration techs are extremely hard to find and ANY refrigeration tech that isn't going to cost more than a new RV A/C unit and be willing to climb onto the top of a RV will be pretty much impossible to find.
Not to mention IF the A/C did indeed lose refrigerant the tech MUST find and fix the leak. Not many are going to be willing to do this on the roof of a RV..
Refrigeration techs now days MUST LOG EVERY OUNCE OF REFRIGERANT.. They must account for all of it otherwise they risk losing certifications and possibly fines..
It isn't like to old days when you simply "topped it off" whenever it got low and ANYONE could buy 30 lb cylinders of ANY refrigerant without question..
