    25-27 years in the business and you post this

    i started unit with my new skills i learned on the job
    Now we might infer from that statement that you were either inexperienced or had no idea what you were doing.

    I know it sounds like we're a bunch of smart asses, but you can see from your post how that might come across.

    Good luck with that unit

    You have to expect a fair amount of ribbing as you climb the ladder. Everyone here I'm sure got plenty, I know I did especially since when started I was working with my older brother. Look at it this way, you're learning and providing us entertainment at the same time

    First of all, I don't think that running a system with a mixture of DRY nitrogen and R-22 or any other refrigerant for a few hours or even a few days will cause a noticeable reduction in the lifespan of that unit.

    I've seen systems operate with air in them for a substantial period of time (given the number of calls before the problem was found and fixed) with no loss of reliability after the problem was corrected.

    As has been said already, recover the contaminated refrigerant from the system and pull a deep vacuum on the system.

    There IS a way to easily and safely re-use that contaminated refrigerant, though. I won't go into it in the open forum, but I've done it a few times and have never had a problem with it.

    couple of our installers did the same to couple different systems. went back on them head pressure bouncing around like a bull in a china shop. reclaim evacuate recharge all good. keep your head up zman, keep learning, you will never stop. the guys that did it at our shop have 15 plus years they just dont read.

    I was really cornfused as to why you were doing an AC start up in January, but being in FL explains alot If you forgot to open the service valves, wouldn't the unit be bouncing off the HPS? If the system is not equipped with an HPS you could have done some major damage to just about every component in the condenser.

    Good luck man, pull a 500 micron vacuum and get your subcool right and you should be squared away.

    PS: This thread is awesome

    Yup. Agree on all points.
