Hi All,
Picked up a used window AC today, which was directly opened up for cleaning and examination. This being an older unit, there are some spots of surface rust on both the evaporator and condenser coils (mainly the sheet metal supports). I am pretty sure a wire brush and some tin snips will take away most of it... But, it did get me thinking... With the whole evap coil going into the glycol bath: sheet metal, copper, aluminum and all... Is rust something that just happens with these projects over long term use? Is there anything I can do now to help prevent rust and prolong lifespan? I am thinking maybe a couple coats of Rustoleum to the supports at least might be some cheap insurance? Is there any detriment? If I am thinking about setting up a glycol loop, would a small sediment filter in the loop be a good idea? Hopefully you can see where I am going with this. I know I am not the first person to do this, and appreciate your words of wisdom and advice.
Thanks,
-Mike
