How to Unclog an AC Drain Line

As temperatures rise, so do the number of calls we receive about air conditioners not working. One of the more common causes of AC issues is a clogged drain line. In this blog, we’ll explore the DIY strategies and tools needed to unclog your AC drain line to ensure cooling comfort on even the hottest and most humid days.

Signs You Need to Unclog Your AC Drain Line

While issues with your air conditioner can indicate several things, certain problems lean more toward a clogged AC drain line being the culprit. These can include:

• Water pooling: Clogged AC drain lines inevitably lead to buildup, which can cause water to pool around the unit.
• Musty odor: Unusual or foul smells suggest stagnant water and possible mold growth in the system.
• Short-cycling: An AC that starts and stops unexpectedly or produces error codes on the thermostat can signal a clogged drain line.
• Visible mold: This is due to heightened moisture and humidity due to stagnant water.

How To Unclog the Drain Line

Unclogging an AC drain line is doable with the right tools and elbow grease. First, locate the drain line, which is usually a small PVC pipe near your AC unit. If it’s accessible, use a wet/dry vacuum to suck out any clogs. Attach the vacuum to the end of the drain line and seal the connection with duct tape if necessary. Let it run for a minute or two.

If that doesn’t clear it, you might need to manually remove debris or gently use a plumber’s snake to push through the blockage. Finish up by flushing the line with water and vinegar to remove residual gunk and discourage future growth. Remember, however, that as tempting DIY fixes can be, it’s always recommended to call in a professional’s help to ensure your unit’s safety and longevity.
