4 Reasons of Water Leaking from HVAC System

Numerous residential, commercial, and industrial facilities maximise the functionalities of heating, ventilation, and air conditioning (HVAC) systems. The main purpose of HVAC systems is to clear off contaminants in the air and improve both the condition and quality of the air. They also help in cooling or heating the air so that a building can obtain a comfortable and healthy environment. 

All these primary functions of HVAC systems can be easily obtained by buildings and properties if they operate optimally. However, one problem that frequently occurs among HVAC systems is water leakage. Water leaking from these systems can not only be annoying, but it can also be alarming as it typically implies more serious problems to the components of the HVAC systems. Additionally, these leaks can also affect the condition and performance of the whole building.

To date, there are 4 primary reasons why water leaking occurs from the HVAC system.

Clogged Drain Line

One of the most common reasons why water leaks in HVAC systems are because of the clogging on drain lines. Any dirt, dust, rust, and other debris that may have accumulated on the drain line over time can easily clog it, which subsequently causes an overflow in the drain pan. Furthermore, having a clogged drain line can instigate an accumulation of condensed moisture within the duct system and around the vent. This accumulation will then cause the water to drip out.

Broken Condensate Pump

HVAC systems that are equipped with a condensate drain pump can effectively remove the water that comes from the dehumidification and condensation processes throughout the building. However, if this specific pump becomes faulty, the water that comes from the building cannot be pumped away anymore. The lack of pumping activity will then force the water to accumulate inside the system and eventually overflow, which might damage some parts of the HVAC system.

Poor Ductwork Insulation

Insulation is crucial to the ductwork as it prevents contact between cold and hot elements. So, if the ductwork does not have efficient insulation, then the cool air from the surroundings may get into contact with the warm duct. The contact between these elements will then cause the formation of excess condensation within the HVAC units, leading to leaks in various parts of the system and from the vent. Poor ductwork insulation can likewise cause mould, mildew, dry rot, and microorganisms to grow.

Frozen Evaporator Coil

Another reason why water might leak from the HVAC system is because of a frozen evaporator coil. This specific part of the HVAC system is expected to freeze up if the units of this system have low levels of refrigerant and dirty air filters. The condensation located on the evaporator coil can freeze up once the warm air from a specific space moves through the HVAC system. Once the HVAC is turned off, the ice that was formed from this contact will start to melt, which makes the water drip out. Clogged air filters, alternatively, can likewise freeze up the evaporator coil since airflow is blocked.
