Why Is My AC Leaking Water?

Discovering water around your air conditioner can be alarming, especially during the hot and humid summers in Conroe, TX. While it’s not uncommon for AC units to produce some condensation, a significant water leak is a sign that something isn’t right. Here are some common reasons why your AC might be leaking water and what you can do about it.

Clogged Condensate Drain Line

One of the most common causes of water leakage in AC units is a clogged condensate drain line. This line is responsible for carrying moisture away from your air conditioner. Over time, it can become blocked with dirt, dust, and debris, causing water to back up and leak out of the unit. Regular maintenance and cleaning can help prevent this issue.

Dirty Air Filter

A dirty or clogged air filter can restrict airflow over the evaporator coil, causing it to freeze. When the coil eventually thaws, the excess moisture can overwhelm the drain pan and lead to water leaks. Changing your air filter regularly ensures proper airflow and helps prevent the coil from freezing.

Low Refrigerant Levels

Low refrigerant levels can also cause the evaporator coil to freeze. As with a dirty filter, when the coil thaws, it can create excess water that the drain pan might not be able to handle. If you suspect low refrigerant levels, it’s essential to have a professional check your system and recharge the refrigerant as needed.

Damaged or Rusty Drain Pan

The drain pan beneath your air conditioner collects water that drips off the evaporator coil. If the pan is damaged, rusted, or cracked, it won’t be able to hold the water properly, leading to leaks. Replacing a damaged drain pan can resolve this issue.

Improper Installation

If your air conditioner was installed incorrectly, it could lead to water leaks. Issues such as improper drainage or an unlevel unit can cause water to accumulate where it shouldn’t. If you’ve recently had a new AC installed and notice leaks, it’s worth having a professional review the installation.
