A condensate pump is an accessory used to move the water (condensation) produced by your AC unit to a drain when gravity alone won't do the job. In many wall mount installations, the drain line can simply run out the back of the wall, but in basements or interior rooms, a pump is required. These pumps are common additions for our concealed duct units which are often tucked away in ceilings where drainage is tricky. You can find reliable replacement pumps and other essentials in our parts section to keep your system running leak-free. Proper drainage is essential to prevent water damage and maintain the lifespan of your multi-zone wall mounts.
