THEY THINK THEY HAVE A FEW AC'S NOT WORKING

It seems I get more and more of these call's where they have multiple ac's down at the same time, last year 2020 really screwed everything up and now I'm getting to clean it all up.

"32% humidity is HIGH." I wish... 83.5% yesterday, temps in the 80s. That split condenser really surprised me with how gunky it was in the inside! It's not what one would expect, because the outer half looked recently-cleaned. I bet somebody hit it with a quick rinse and pushed all that crap into the inside, and then left it to dry.

aye, same here, the lowest I remember ever seeing the humidity (and i check frequently, multiple times a day, even in winter) was 43%. also 90% is incredibly common, and the highest ive ever seen was 108% when the temperature dropped rapidly one day, and walking outside made you feel like you were drowning.

Or are there systems out there that bring that terminal back to a thermostat or building control system for alarms or other purposes? (And finally, that was a nasty split)

On split coil condensers I've had a fair amount of luck getting the sandwich crap out by simply deluge flushing from above and not pulling them apart much. On residential units people expect to last 20 years you don't want to do much flexing. Used a gallon pitcher that has that shield over-top the pour like a watering can, splooch muck gone.
