It failed around the last day of December. I think the total run-time was about 45 days..

The day before I was supposed to get a replacement unit (outdoor unit), Sanyo USA sold
all 70 units they had in stock to some dealer.. So, I had to wait for the next shipment and customs delays etc.

I have my own ideas about what may have caused the leak, but the odds are it was just a weak spot in the copper, caused by a tad too much heat..
R410A runs at a higher pressure than the old refrigerants and that could be a factor..

From what I've been able to find out, this Sanyo model line (Inverter using R410A) has been very popular around the world for around 5 years now, and seems to be very reliable.
