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?...

For the future benefit of those who do not understand RV air conditioning but just want to post something, these compressors are hermetically sealed units. There are no shaft seals to leak, they do not leak, and they are (the compressors) are not serviceable, only replaceable.
Also, you can not recharge these units by simply adding refrigerant until the suction line sweats back to the compressor like you could with R22. You have to charge by scale, charging cylinder, or by super-heat measurements. You would also have to install two service ports. If you do not have the converter device that allows you to charge with vapor, you have to charge with liquid on the high pressure side. If you do not already know and understand this, you should leave it to the pros.
