I have a chiller on my system. It's in my sump room and the exhaust is drawn outside by fans.
I also use computer fans over the sump. This helps keep the chiller from running as much but ya, the evaporation is much more.
With all the gear I don't get any fluctuations.
I also have AC in both our Master and my sump room so when things get unbearable I run the furnace fan to circulate the sweeeet cold air
