How to Unclog Your AC Condensate Line

how to unclog your ac condensate line

You may not think that a puddle of water sitting next to your air conditioner’s condenser is a big deal. However, it is a sign that the unit’s condensate drain line has a clog. Under normal circumstances, the water that is created during the cooling process will drain away on its own. However, when it doesn’t, you may have a mess on your hands.

What Causes a Condensate Line to Clog?

Condensate lines and drains can easily get clogged with various types of debris that can built up in the pan of your condenser. This debris can be anything from mold, algae, hair or rotting vegetation. If the clog is not removed, water will continue to build up in the pans of your condenser, and possibly in the pan of the unit’s evaporator indoors, causing damage to your system.

How to Clean and Unclog the Condensate Drain Line

When it comes to removing a clog in a condensate line, a wet/dry vacuum is your best bet. You can usually clear a clog in the line with just a wet/dry vacuum. You can gain access to the line by removing the system’s access cap or unscrewing the PVC pipe. Once you have the line open, use the vacuum to remove any trapped water and the clog.

Never pour bleach or other household cleaners into your condensate line. This can damage your system and your home. Only use cleaners that are made specifically for cleaning condensate lines. If you want an all-natural option, a solution of vinegar and distilled water can help prevent algae and bacteria growth.

Tips to Clean the Condensate Drain and Tray

It is not difficult to clear your unit’s condensate drain and tray. To avoid shock or electrical damage, switch your air conditioner to “off” on your thermostat and then shut down the power from the circuit box. Pour water into the condenser pan outdoors. It should drain away freely. If the water does not drain, the condensate drain is probably clogged. Check to see if there is any debris stuck in the drain. Remove any visible debris and retest for proper drainage.
