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.
