    13 year old pkg

    I was sent to give a free second opinion today and this is what I found:

    Expulsion was blanketed with about 1/2 inch of debris...not exagerating. After I cleaned it this is what I had.

    Superheat 45*
    Subcool 12*
    Comp amps 14.3
    LRA listed at 15
    50 low / 140 high
    Con coil could use some attention as well as blower wheel but not clogged.

    Added some r22 and brought my low side to 60 psig with a super of 25. High side and sub didn't move.

    I do so few pkg units but I'm thinking the clogged evap coil worked the compressor too hard and now it just won't pump any more...condemn the compressor or the whole unit due to condition of coils?

    Thoughts or suggestions?

    Your LRA (do you mean RLA) is 15amps and you're pulling 14.3amps.....don't think you conclusion of not pumping, holds up.

    What kinda of ambient and indoor load did you have? Fixed metering or TXV?

    what makes you think the coil is clogged? Did you check the filters?

    If you have split experience then you can handle a package unit. They're actually about the easiest thing for a HVAC tech to work on. That amp reading means your comp isnt the issue. Clean up the evporater coil and recheck your suction.

    What kind of load is on this unit ? OAT ?

    Find and repair leak. Replace drier. Weigh virgin refrigerant back in.

    Rain on the condenser coil won't help get your head up.
    ENJOY THE RIDE
