Own An HVAC System? 3 Things To Know About The Condensation Drain


Your air conditioner does more than pump cold air into your house. The AC also is responsible for removing humidity in the air that it processes. All this moisture must go somewhere once it is removed, which is where your condensation drain comes in. This drain is the pipe that is often dripping water when your air conditioner has been running for a while. Here are 3 things to know about the condensation drain.

How the Condensation Drain Works

The condensation drain is one part of the entire system's drainage system. The moisture from the air is removed, and then it drips into the condensation pan. This pan is often located under the unit's evaporator coil, where water collects before it flows through the drain line.

Some units will use gravity to allow the water to flow to a drain located in the floor. Other units will use a pump to force the water out to a different drain, such as a utility sink in the laundry room or a sewer pipe.

How the Condensation Drain Can Malfunction

The biggest problem with a condensation drain is that there can be a clog somewhere in the line. It could be caused by debris that got into the condensation pan, and it is not allowing water to flow to the drain pipe and exit your home. Water will collect in the pan and potentially grow mold. There is also a risk of the pan overflowing with water and causing damage to the surrounding area.

Some units will have a sensor that is designed to shut down the air conditioner if the condensation pan is about to overflow. This could be one reason why your air conditioner stops working suddenly with no major sign of a malfunction. Find out where your condensation pan is located and see if it is full to fix the problem.

How to Fix a Condensation Drain

Try using a shop vacuum to remove anything in the drain pipe that could be causing the clog. Fixing the problem may be as simple as scrubbing around the pan's drain to remove buildup. Bleach can be used to remove gunk that has blocked the drain, while killing any bacteria in the drain at the same time.
