Where Is the Condensate Drain?

On most air conditioners, you’ll find the condensate drain attached to the condensation point. Most AC units are located in a cabinet with quick access to a drain hole. This location allows the drain to work with the flow of gravity.

In other cases, condensation goes into a drip pan and is pumped out. When you experience a drain clog though, problems can occur. We’ve listed below a few of the most common condensate drain issues.

Mold Growth: Naturally, during the summer cooling season the drain tube that leads away from your air conditioner’s drain pan is almost always damp. This makes it a prime location for mold growth, which can have a negative impact on your health and the health of your family.

Drain Trap: Your condensate drain has a U-shaped trap similar to the trap underneath your kitchen sink. In order for water to properly flow out of your system, the condensate drain must work effectively. Sometimes, traps may become blocked, or they can dry out. Not only can this cause mold, it can also cause sewer odors and gases to back up into your home.

Leaks and Flooding: If mold, algae growth, or other debris causes a clog in the condensate drain line, then the condensate pan can become filled with water, and eventually overflow. Water damage of this kind can affect your flooring, drywall, and air conditioning equipment. This is particularly true if it goes unnoticed for too long of a time.

If you suspect that you have a problem with your condensate drain system, the best thing to do is to call a professional to inspect your system, and make repairs if needed.
