    Another thing you can do is pull all the filters and grills on the air handler’s and get some coil cleaner or spray nine for that matter and some wire brushes and clean out the coils and get all the dirt and Schmutz out of there so the air flows through nicely.

    Also generally at the bottom of the coil you’ll see a little nipple for the condensate line make sure that’s cleaned out two with a coat hanger throw some water in there with a cop and make sure it drains

    You will probably have to remove the four screws on the blower fans to get in there good to clean remove the four screws and gently move the direct drive fan blade and motor out of the way so you can clean it’s not a big deal

    Not wire, plastic brush.
    We use the plastic fin tools and compressed air or nitrogen.

    I used sweetie puss’s toothbrush one time ...I caught hell for that!!
    Anyway a stiff toothbrush did a good job to get in the little corners around the fan shroud...

    Was also contemplating a self contained unit behind the TV in the entertainment center...how high will those water pumps push the water up?

    About 4/5 feet. Maybe higher if you get a bigger unit than what’s called for.
    You should be ok to put one there.

    Here’s the deal at least with Cruisair, your 16000 btu Compressor is really a 14,000 or 14,500 compressor it should be stamped on the top or on the side.
    They were especially made for cruisair.
    You may have to go with a 12000 btu Tecumseh unit which you can get from United refrigeration that’s what I had to do with one of mine and it works just fine.
    BUT look around you may find one, or you will have to buy the whole unit complete.

    Boomer; If I am reading your post correctly, your AC guy is the one I recommended to you, and he offered to give your money back. If so, I guess we can still be on good speaking term?

    My friend at the marina is a commercial refrigeration guy for commercial kitchens / supermarkets etc he and I did the work yes it was an R 22 compressor and we had to change out the compressor starters, I think that’s what they were called , to work with the 12,000 b t u unit.

    When you fix junk, you still have junk. Your unit is what, 20 years old? REPLACE the entire system, with a new 410 system which is more efficient anyways, it is past it's life.

    Just a heads up...when you load that "old" air handler with new pressures from a new compressor system, it is now the weak link. Keeping the r22 means you'll need the compatible air handler when that time comes. Be careful that you're not spending yourself down a wormhole by sticking with the r22......

    THIS. I would never repair an R-22 unit or put a new compressor unit with a 20 year old air handler. A/C's work as a package or system.

    Think I'm going thru this right now.... Not long after I bought my Yr2000 Ocean, one of my AC compressors died. Apparently it was rotted out. Replaced the compressor with a new one. Shocking cost of $4500 for the part alone vs $1500-$2k for an entire self contained unit. Flash forward a couple of years and now the air handler has a leak that needs to be repaired.
