    you can always call the manufacturers customer service line and list a complaint against the company if they are an authorized dealer

    Doubt you'll find many systems that had nitrogen flowing through their line sets in new construction. And they do last a long time.

    Should he have done it? Yes. Is it going to have a problem because he didn't? Only time ill tell.

    How many times must one fix something before it is fixed?

    Good point! I guess if he bought a new Corvette and it was supposed to be Blue, when they brought a Red one out, he would just get in and drive off?

    Your required to drive the speed limit and come to a complete stop at all stop signs or red lights, you ever broke either law? if so your as bad as the guy that did not flow with nitrogen, because the law states in there instructions to do so.

Came back and finished up. The company insists nitrogen purging in not necessary but I've heard it's more critical with R410A. So they got their money, we got a nice system that hopefully won't fail anytime soon. And yes, it does say to purge with nitrogen in the installation manual.
    So he did not pressure test it either. Lets see here. #1 he added a unneeded drier in the liquid line #2 he did not purge with nitrogen #3 he did not pressure test the system and #4 he did not use a micron guage these are the known items he blew it on makes me wonder

    Do we know these other things to be fact, or are we making assumptions?

    you are obligated to install the product to the mfrs. listed instrucitons. Now, some things in IOM manuals are mandatory and others are considered 'best practices'. Before you hang this guy out to dry, you would need to document where it is written as mandatory he purge with nitro. Sure, most guys have heard it for yrs we should flow N2 but a lot still don't and mfrs. just don't have the budget to test and prove a compressor failed because the tech skipped the N2 and the resulting crud killed the system.

    How would he pressure test the system if he did not have nitrogen or a regulator

    By opening the valves on the condensing unit and using a leak detector, eyes, ears, and maybe soap bubbles?

    Nitrogen isn't the only way to leak check a system.

    Now, about that micron gauge....

    That would be an EPA violation.

    Thumbs down please close this thread

    First of all, we're trying a case in abstentia. We weren't there. We don't have pics of the guy working. We can only go by what the homeowner has related to us. The homeowner is withholding payment based upon information gleened online from a blog. How would you feel if someone stiffed you on those terms?

    She may be telling the whole truth or there may be more to it. We don't have the IOM manual, what local codes are, what the mfrs warranties say about it, etc. I really think this thread needs to die out since it does no good to anyone.
