How to Clean Your Air Conditioner Condensate Line

When your air conditioner is operating correctly, the temperature difference causes moisture to accumulate on the coil. That moisture has to drain away from the unit and the condensate line is what takes the water to the outside of your home.

In a perfect world that water would be completely clean and flow freely through the condensate line forever. Unfortunately, that is rarely the case. The water can contain algae, dust, and other debris that will clog the line. Removing the clog is a simple procedure and is usually a part of the seasonal service you receive from your HVAC contractor.
