    goodman piston size

    I bought some left over r22 goodman 13 seer condensor units. A gsc 2 ton and a 2 1/2 ton. Neither of these units had their customary piston connected to the condenser under the electrical panal. I decided to look online and get the piston size but under piston size for these 2 units just have a slash. And no mention of a txv or * to tell me what to do.I could look at an old piston chart or guess and get really close. I do need a piston size but why would they change from the norm? Thanks

    Cause 13 SEER condensers don't use the same size as 10 SEER condensers did.

    I have the .061 for the 2 ton, but according to my notes, the 2.5 should be a .065.

    Are my notes wrong or what?

    4ton

    I have a Goodman 93% airhandler with a 4ton coil CAPF4860C6BA (bought in Dec09) and a Goodman NIB GSX130481 condenser. There is a .093 piston in the coil but I dont know or have a chart to know what piston I should use for R410A. If someone could tell me what size should be in it I'd be grateful for your help.

    Your contractor should know how to read the manuals to know what size piston to use.

    Thanks BUDDY. You just won me $100 on a bet that the first think anyone would reply would be to snub someone asking an honest question. The answer is that the supplied .092 piston is used on that coil as a 5ton and a .080 is used on that coil as a 4ton. Next time a man asks a question trying to learn something don't look down YOUR NOSE on them just give them the correct answer.

    Next time. Don't ask questions that make you sound like a DIYer.

    Don't forget to send me my half of the 100 bucks.

    Read site rules. And then you'll know why you won't get answers to questions like that.

    You come onto a professional HVAC site that specifies no DIY, don't post anything to indicate that you are in the HVAC business, and then have the audacity to think you have a right to post crap about a known pro on this site? Congratulations! You are our new troll for the day

    Besides. How was I suppose to know it was a "man" asking the question.

    It could have been a "woman". ROFL.


    But I still want my 50 bucks.
