Discovering your air conditioning system is dripping water can be a cause for concern, particularly during the sweltering heat of summer months. Not only does this issue signal that your HVAC system may be operating inefficiently, but it also poses the risk of water damage to your property. This post aims to determine the common reasons behind this issue to help ensure your air conditioning system returns to its optimal functioning state.
Air conditioners function by transferring warm indoor air across the evaporator coil, where it gets cooled before being circulated back into the room. During this process, moisture in the air condenses on the cold surface of the coil, similar to how droplets form on the outside of a cold glass on a humid day. This moisture then drips into a condensate pan and is expelled from your home via a drain line. While this is a normal aspect of air conditioner operation, excessive water leakage indicates a problem that needs addressing.
Several issues could be causing your air conditioner to leak water, many of which are prevalent in humid climates. It’s crucial to understand these problems so you can take the necessary steps to fix them.
A leading cause of water leaks from air conditioners is a clogged condensate drain line. Over time, this line can become blocked with dirt, algae, and other debris, causing water to back up and overflow into your home. Regular maintenance, including cleaning this line, can prevent clogging and leaks.
The condensate drain pan may corrode or crack, leading to water leakage. This is especially common in older air conditioning units. Inspecting and, if necessary, replacing the drain pan can solve this issue.
Restricted airflow or low refrigerant levels can cause the evaporator coils to freeze. When they thaw, the excess water can overflow the drain pan, leading to leaks. Ensuring proper airflow and refrigerant levels can prevent this from occurring.
A dirty air filter restricts airflow over the evaporator coils, potentially causing them to freeze and leak water as they thaw. Replacing your air filter regularly is a simple but effective way to prevent this problem.
Similarly to dirty air filters, low refrigerant levels can cause the coils to freeze and leak water. If your air conditioner is hissing or bubbling, it could indicate a refrigerant leak, which not only causes water leakage but also decreases the efficiency of your unit.
Incorrectly installed air conditioning units or improperly configured drain lines can lead to water leakage. It’s imperative to ensure that your AC system is installed by a professional to prevent issues.
