Installing the Carrier 51GMA228301 27,500 BTU International Series air conditioner from 1988 into the living room for the 2024 cooling season. The install posed numerous challenges due to the deterioration of the basepan. I don't think I will be removing it for the Winter anymore, I feel like this process is causing more damage to the machine than the Winter would cause.

Despite all the rust, the machine still holds a full charge of R22 refrigerant and cools as well as it did the first year it was used. The Japanese Toshiba compressor and American General Electric fan motor are both still working perfectly and will likely continue to do so for many years to come.
