What Does The AC Drain Line Do?

The AC drain line does exactly what you might expect it to, given the name. The air conditioner drain line, or condensate line, collects the humidity removed from the air as a natural part of heating and cooling, and carries it away to be distributed outdoors. A drain line is typically made of plastic (usually PVC) or metal in some cases. If the drain line is clogged, disconnected, or not functioning properly, it can create other issues with your HVAC system.

How To Know If The AC Drain Line Is Clogged

It’s important to know the signs of a clogged drain line so you can address it before it creates further complications. Signs the condensate line is clogged can include the following.

  • Water pan overflowing. Water collects in the condensate pan or drip pan before being transferred through the drain line. If there’s a clog, the water won’t be removed and will overflow from the pan. If you notice water collecting around the unit, this can be an indication that there’s a drain line clog.
  • HVAC Issues. If there’s an issue with an HVAC part, it usually manifests as additional issues with the system, such as the AC not blowing cool air or not turning on. If you’re unsure what may cause your HVAC woes, it’s best to contact a professional HVAC technician to diagnose the issue.
  • Smart Norifications.Newer models of HVAC systems sometimes have smart technology that can alert you to clogs in the drain line. You should never dismiss any notifications from your HVAC system!.

What Causes A Clogged Drain Line?

There are two common causes for a clogged drain line: either in the line itself or outside where the line empties. While the drain pan collects water, it can also collect other debris, such as dust. Additionally, algae and mold are prone to grow in these wet conditions. Both of these sources can cause clogs over time. For the outside portion, leaves, dirt, and debris can accumulate, making it difficult for the line to drain properly.

How To Clear A Clogged AC Drain Line

There are some DIY methods for clearing clogged drain lines, but they may not always be effective or damage the lines, causing further issues and needing emergency AC repairs. Unless it’s an outside clog that can be easily cleared away, we always suggest contacting a professional HVAC company to clean the lines properly and safely. Additionally, as part of our HVAC maintenance, we can clean drain lines before they become clogged and pose any issues.
