Why is a Clogged AC Condensate Drain a Problem?

Some of the most common calls we get for air conditioning problems are in regards to a condenser making strange noises or insufficient airflow or cooling power. These are examples of very serious air conditioner problems that should be repaired right away, and are typically quite obvious. There are some not-so-obvious components of your air conditioner, however, that can cause problems too, such as the condensate drain.

What Is the Condensate Drain?

As your AC system runs, it absorbs heat along the evaporator coil. This process draws moisture from the air, which collects along the coil, and eventually begins to drip. This dripping water should be caught in a condensate pan, where it then needs to be drained through the condensate drain and then to a specialized pump that removes the water away from your home.

How Does a Condensate Drain Become Clogged?

There are two possible causes of a clogged condensate drain. Algal growth is one possible cause: a common problem when there is humidity in the air. The second cause is dirt that has entered the air conditioner’s cabinet, and then made its way to the condensate pan.

So, What’s the Problem?

If your condensate pan becomes clogged, then it can easily cause an overflow of water, since the pan is only about an inch deep. If that water were to splash onto electrical equipment, you could have a fire on your hands in the worst case scenario, or at least water damage and corrosion to your HVAC system. Either way, you’ll have expensive repairs on your hand.

Any water that leaks from your AC system has the potential to do a lot of damage to your home. Additionally, it can create harmful and unhealthy mold and mildew to form. If you notice or suspect that your condensate pan has become clogged, be sure to give our professionals a call.
