Anyone Recharged Their A/C Refrigerant?
I have a Coleman Mach 11K unit that has been blowing warmer and warmer for about a year now. The **** thing is only 3 years old with VERY little use. Can't be expected to buy a new one already, right?...

As a suggestion, you might want to install the service port and determine if there is any charge left. I'm assuming you have a leak tester? Using soapy water hardly gets it as there are too many places hard to see. If it's completely empty (probably) you could get a can of 134A (automobile refrigerant) and charge it with that just to find the leak. This would be cheaper than chasing down the 410 and wasting it for leak testing purposes. You are going to have to evacuate it to fix it anyway so the 134 will go away. I'm thinking you will find out why they are called 'unserviceable'. Usually these units last a long time...you just drew the short straw. If you have "Big Lots" stores near you, they are frequently the cheapest place to get 134A.
By leak tester, you mean UV dye and and a blacklight? Cause that's what I've used on every auto A/C system with a leak.
From what I've read on the "pro" HVAC sites, 410 and only 410 is designed to run in these compressors due to the higher operating pressure. I have a bunch of 134 in the garage though.

Yeah, that's the story of my life lately.
