Why Is My HVAC Leaking Water?

HVAC systems are known for their reliability, making it quite unexpected when they experience issues. If you see water or excessive condensation pooling around your HVAC unit, you may be asking yourself, "What is causing my HVAC system to leak water?

Clogged Condensate Pipe

One common culprit for HVAC leaks is a clogged condensate pipe or pump. Over time, dust and dirt can build up, hindering the flow through the drain line and potentially leading to rust or algae accumulation. The constant exposure to moisture can cause the condensate pump to clog or wear down, resulting in mold growth or decreased efficiency.

If you notice constant water flow instead of a slow drip, it could indicate a disconnected or punctured condensate pipe. In such cases, it's crucial to have your HVAC system serviced promptly to prevent further damage. 

Frozen Evaporator Coil

Another potential issue to watch out for is a frozen evaporator coil. If the coil freezes, it can lead to leaks in different areas. This typically happens due to a dirty or clogged air filter, or low levels of refrigerant.

A dirty air filter can make your HVAC system work harder than necessary, causing the evaporator coil to become colder than usual and freeze. To check if the air filter is the to blame, simply remove it and look for excessive dust and dirt buildup. If it's clogged, replace it promptly.

If you notice leaks in the refrigerant lines or if your system isn't cooling your home as effectively as before, it could indicate low refrigerant levels. Another sign of low refrigerant is a hissing sound coming from the system. Be sure to address any issues with your HVAC unit promptly to prevent further damage.

 

If you have any concerns about the performance or potential issues with your HVAC system, it is advisable to reach out to a qualified technician to conduct a thorough inspection of the system.
