A leaking ductless AC system can be frustrating and potentially lead to costly water damage. According to the U.S. Department of Energy, leaks from HVAC systems account for 20% of water usage in households. Some common causes of water leaks from ductless AC systems in Harrisonburg, VA, include the following.

Clogged Drain Line

One of the most common reasons for a leaking ductless AC is a clogged drain line. As the system cools the air, it removes moisture, which drains away through a condensate line.

If this line becomes blocked by debris or fungal growth, the water has nowhere to go and will start leaking from the indoor system.

Improper Installation

Ductless ACs require careful installation to ensure proper drainage. If the condensate line isn’t correctly pitched or connected, water can back up and overflow from the system. Consulting with our experienced technicians in Harrisonburg, VA, is crucial for proper installation.

Frozen Evaporator Coil

Another potential cause of water leaks is a frozen evaporator coil. The restricted airflow can cause the coil to ice over. As the ice melts, it can cause water to drip or pour from the system.

Damaged Drain Pan

The drain pan catches any condensation that accumulates in the system. However, if the pan becomes cracked or corroded over time, it can start leaking water onto the floor or walls around the ductless AC.

Aging System

Like any mechanical system, ductless ACs wear down over time. As the system ages, seals and gaskets can deteriorate, causing water to escape. If your ductless AC is more than 10 years old and leaking, it may be time to consider replacement.
