Do you need a condensate pump for your ductless mini-split heat pump or air conditioner? Yes, no, maybe? If you don't know whether or not you need a condensate pump, this article is for you.

What is a Condensate Pump?

First, why do we worry about condensation in a ductless mini-split anyway? All air conditioners create condensation (i.e. - water) as a byproduct of cooling. Because, the way they cool down your house is by reducing the interior humidity. Dehumidification creates water, and that water has got to go somewhere. Ideally, you want that water going outside of your house. In a central air system or a ductless system, the condensation will build up in a drain pan. From the drain pan, the water is emptied outside the house via a condensate drain. In many cases, this is just a simple gravity drain. This system mostly works great. Until you want to put an air handler in a place where a gravity drain won't work. Like in a basement. Or on an interior wall, and there is no easy way to run a drain hose outside without first going up through an attic space.

Prevent Water Damage with a Condensate Pump

Obviously, a condensate pump is the solution to these problems. A condensate pump is a relatively small, simple device. You install it with the air handler. When the condensate builds up, the condensate pump pumps it out. It uses mechanical force to remove the water, so you don't have to worry about water overflowing the drain pan. So, if you want to put a ductless mini-split in a location where gravity-fed drainage would be an issue, get a condensate pump. It will keep the water moving out while you stay cool.
