How to Keep Your AC’s Drain Line Clean

The drain line is a key part of what allows your AC to run smoothly; a clogged drain line can compromise your unit’s performance or even prevent it from working at all. But what should you be doing to keep your AC’s drain line clean? Learn more about what the drain line does, how to maintain it, and what to expect if you need to bring in outside reinforcements.

How Does a Clogged Drain Line Impact the AC?

The AC’s condensate drain is designed to remove the water that is generated by the evaporator. (This evaporator converts the AC’s refrigerant from liquid to gas form, creating condensation.) If the condensate drain is clogged by algae, mold, or the other debris that tends to form in pools of standing water, it could compromise your AC’s ability to convert refrigerant into gas, forcing the unit to work harder and reducing its lifespan.

Generally, you’ll be able to tell that your drain line is clogged by the amount of standing water in the condensate pan.

Maintaining Your Condensate Drain

Keeping your condensate drain clean and clear doesn’t need to be time-consuming or complicated. By taking a few minutes every couple of months to clean the drain line, you’ll be able to minimize future issues.

First, turn off your AC’s power and locate the drain line. Use a thin, stiff brush (like a small bottle brush) and push it into the end of the drain line to dislodge any debris. To tackle potential clogs that are higher up in the line, use a wet/dry vacuum to suction out the drain line.

Next, find the vent tee and remove the PVC cap. (This tee connects your drain line to the drainage tray.) Pour some diluted vinegar into the drain pipe and allow it to soak for a few minutes. The acidity of the vinegar will disintegrate clog-forming materials; while some use bleach for this process, it’s not as effective as vinegar when it comes to dissolving drain line clogs.

Getting Professional Help

If, despite your regular maintenance, your drain line is starting to act as though it’s clogged, it may be time to bring in the professionals. An AC technician has specialized tools that can blast away any clog, along with preventive treatments and concoctions that will help clogs from forming in your condensate line in the future. Though DIY maintenance and cleaning can go a long way toward reducing clogs, sometimes you need the skills of a professional.
