# How to Clean Out the Tubes on My York Heat Exchanger
A heat exchanger from York heats air and distributes it through the home ductwork system. During the heat making process, a lot of condensate is made and drained through the drain line in the system. The drain line runs from the top of the system, down a PVC drain line and out of the home. Algae will build up within the line over time if it is not cleaned out regularly, which prevents the system from draining.
