HI; I took a Klimeaire 12K btu unit (a long story of how I got here) and charged it with R290 from my local hardware store. I used my IR scanning thermometer to scan the condensor coil to indicate the amount of charge in the system> I eventually got a Delta T of 22 degrees. I ran the system for a couple of days. This system was set up in my shop so I could play with it. Once I determined that it was working fine. I evacuated it and recharged it with R410a. re-installed it into the rental unit and it worked through the winter just fine...
