I have a portable AC unit which run from about April ’til October. It has a reservoir that needs to be emptied about every 4 months, and even then, it’s about 2 tablespoons of water. How is this possible?

Question

I’ve had portable AC units before that had reservoirs which needed to be emptied a couple of times per day (constant use) and I’d have to dump a gallon of water out.

I don’t understand how this portable AC unit is able to function without moisture collecting in large amounts.

This is a portable, not a window-mount. It doesn’t drip water from the out-duct.

Additionally, about every 30 minutes it makes a sound that is very clearly ‘trickling water’. Not sure if that helps, but I’m trying to add as much info as possible.

I’m baffled

When I lived in Vegas (20% humidity), my portable A/C never accumulated any water from the condensate drain. Now I live in SE Texas(80% humidity) and the same portable A/C generates about a pint/hour.

Where do you live?
