    Carrier 30RBA080 condenser coil replacement

    I'll be replacing all four condenser coils this weekend. Crane off the top and dismantle all the supports. They're 380 & 480lbs shipping weight so they're heavy and fragile. Any help on tips getting them in and out without any damages? Thanks ahead for any help..

    Lots of screws, crane, and three guys. 4 would be better but it's ok with 2 techs and a newbie. Coils are larger and delicate, careful of the coil return bends when sliding it in with the crane. My first and probably my last 30RB condenser coil replacement, which is fine with me. Two of the four liquid line swage fittings were only in a 1/4", surprised they never failed. All good tho.

    Are they microchannel coils by chance? We just installed one on our campus and I got the tube and fin coils....im praying they last. Unfortunately Carrier was the low bidder

    Chiller is 7 years old. Copper tubes, copper fins, and it was coated by Carrier. 100 yards from the water.

    Do copper fins ever survive next to salt water? What condenser coil coatings have been successful? (On copper? or aluminum?)

    What's the environment the fins are in? Looks like a compost farm or something?

    If a "little" coil cleaner mixed with water is "good", straight cleaner must work absolutely "great", right? Ever start washing a coil with just water and the fins just flake right off? And bubbles everywhere? Previous tech must have used the whole gallon on that one unit...

    Copper fins do much better than Aluminum near the ocean. Good coatings can increase salt spray time from 600 to 3000 hours or more depending upon the vendor.

    It's near the ocean, within 100 yards. No compost or dirty air. It's typical of salt air. Corrosion turns the metal to copper dust. If it wasn't copper fins, it'd be no fins just copper tubes. All three chillers within a mile of each other look like this.
