A condensate pump is an optional accessory used when your indoor unit cannot drain water by gravity alone. This often happens when a Concealed Duct or Wall Mount unit is installed in a basement or an interior room. The pump sits inside or near the unit and automatically pumps the collected water to an outdoor drain or sink. We offer reliable Condensate Pumps that are designed to operate quietly and fit within tight spaces. These pumps are essential for preventing water overflow that could damage your flooring or ceiling. Most pumps include a safety switch that will shut off the AC if the pump fails to prevent a flood. It is a common addition for commercial PTAC installations as well. Regular cleaning of the pump's reservoir is recommended to prevent the buildup of slime or debris. Including a pump in your setup provides more flexibility in where you can install your climate control system.
