Probably brand new. Since 2010 the manufactures have not been able to ship units charged with R22 but they can ship what they refer to as “Dry units” these units have no refrigerant ship with the unit but normally have a positive charge of nitrogen gas to keep moist air from entering the unit.

Not true R22 is in a phase down cycle see the following source
I haven’t bought any for a while but that sounds about right.
I remember buying it for 0.60 cents per pound.

I think for quite a while, there are replacements being produced for R22 but right now they cost as much as R22 so there is little to be gained by using them.
The replacements have similar pressure temperature and enthalpy to R22

One again not true please refer to the EPA site.

Not at higher Ambient temperatures

Not sure what your point here is but R410a is normally used as a medium temperature refrigerant intended to be used in things like air conditioners.

No warrantee on the refrigerants only the equipment. Since I am out of the business can not address the new warrantees but you can Google some of the big manufactures and check the warrantees on the “Dry Units”.

I am not sure who you are addressing here but I sure cant answer that one.

R410a is not a magical cure refrigerant, the lubricating oil that is used in the 410a sealed units is very hydroscopic, some tests have even proven that POE oil stored in a plastic container will absorb some moisture in a new sealed bottle. Moisture in a system will react with the oil and will deteriorate the motor windings and in some cases cause sludge formations that can plug up a system.
Carless installation practices that might not matter in an R22 system can spell sudden death for an R410a system, special care must be taken, things like purging nitrogen while brazing, pulling a deep vacuum verified by a micron gauge and the use of filter dryers.
Actually not only does R410a require higher operating pressures which can result in stress on the components but if you study the performance curves of the refrigerants at higher ambient temperatures R410a’s performance actually drops off.
Having said all that if I need a new unit it would be 410a but you can be sure I would make sure the installation was up to snuff because asfar as I am concerned, that is more important than what brand you use

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
