It’s bothered me that A/C’s are set by temperature. Depending on the moisture level, 70 can be stifling, while 80 is quite comfortable. I’ve had to lower my central A/C by a degree or two because the system was just not running enough to remove the water.
Seems to me A/C’s should have a relative humidity selector... humidistat.
I have a Lennox AC that's about 7 years old and it has a programmable thermostat which allows you to turn on dehumidifying and keeps the humidity below 50%. Most of the time the screen shows "cooling" but occasionally it says "system is dehumidifying". When that happens the temp will usually drop below the system temp setting.
Yes - I bought and returned a small window AC for my “office” recently, because the lowest setting of the thermostat would kick the unit off when air in the immediate vicinity was still around 76 deg. F, and the unit would not run enough to dehumidify the entire room. I bought a different unit and it stays on more of the time, with a little thermostat to spare: Right by the AC, “incoming” air is about 74 deg. The average room temp is now more like 78 deg., and the room is much dryer.
I also noticed that Subaru has dropped the minimum AC temperature setting in their Outbacks - probably to help clear out moisture in the cabin in cool but damp internal conditions, where one might come in to the vehicle wearing “warm” clothing.
