    Is anyone still getting dry r-22 condensers

    In my area there haven't been any available for a few months. Just curious is all.

    You can't get them anymore.

    You CAN get 407C condensers, though.

    Practically identical....

    The dry units here were all 13SEER, once the supply was gone, we can't get any more. I've seen advertisements for the 407c units, but they are not in stock locally yet.

    Not available anymore....In 1987, there is a mandatory phase out of certain products whose emissions were deemed harmful to the environment. In the US, the protocol was put into law through the Clean Air Act, and is implemented by the EPA. The law requires a phase out of R22 as a refrigerant. So after few years the supply was decreasing...

    R407C units are basically R22 units. Amazing how a simple change of lettering skirts the rules.

    The R407c units are in stock locally in 14 SEER now. I installed one this week. They are almost dry ship, because they only have 1 pound of R407c in it. The one I installed took 6 pounds, they are a nice option to add for budget projects.

    Why only 1 pound instead of either a full charge or a nitrogen charge?

    I would assume cost is the number one reason and 2 is so you can pull it easily and charge with R22 if you want to.

    Commercial condensers usually come with a holding charge of about 1 pound of refrigerant and the rest is field charged. So I guess that’s where they got the idea.

    I actually asked that exact question, the answer given, it’s part of the loophole that allows them to sell those units. I gave the R407c option only because it was quicker for me to get them cooling again when I found their compressor shorted to ground.

    In my area (lots of hacks)... dry units got charged without pulling a vacuum on the unit...
    Thus mixing the N2 holding charge with the refrigerant (not kidding, I found this repeatedly).

    So if the factory puts just a small holding charge of 407C in the unit... then the hack installer can pull a vacuum on only the lineset and coil (like they normally do with a coil change)... and charge with 407C.

    I am gonna have to talk to the guy at URI... if they are gonna get '14 SEER 407C units'... I may well use them as an option! Reason is: lower pressures should mean longer evap coil life!
