Does a Mini Split Condenser Emit Water? - Ask the Expert Episode 255
Today's question comes from Edith Robertson.
"Hey Dan, does the condenser unit of a mini split emit water? The unit I'm looking for has an outdoor drain line, but is there water other than the drain line water that might cause dampness on a slab on grade? The specs say the condenser may cause dampness, so I'm thinking of having the condenser installed several feet from the indoor unit on the ground rather than on the slab on which the stud wall is built. Any thoughts?"
Yes. A condenser of a mini split can have condensate coming off of it other than the drain line. If it's a heat pump and you're using it to heat with in the winter, there can be condensate build up in the winter. That will drain out through the condensate drain line through the condenser. It's usually not a big deal.
Generally, when you put it on a slab you want to angle it slightly so any of the condensate will drain off. If you just want to put it on the ground, that's perfectly fine too.
This is all just a normal part of condensate operation.
