Clogged Air Filters

One of the most common ca why your air conditioner may be leaking water is due to clogged air filters. When the air filter is dirty or clogged, it restricts proper airflow, causing excess condensation on the evaporator coil. When there is too much moisture in the coil, it can overflow and cause water to leak. Changing the air filters at least once every three months can help you avoid this problem.

Blocked Drain Line

Another reason why your air conditioner may be leaking is due to a blocked drain line. The drain line is responsible for removing excess condensation from the air conditioning unit. However, the drain line can become clogged with dust, dirt, and other debris, which can cause the excess water to overflow and leak. Getting your drain line cleaned regularly can prevent this issue from arising.

Low Refrigerant Levels

The Refrigerant is responsible for cooling the air in the air conditioning unit. If the refrigerant levels are low, it can cause the evaporator coil to freeze over, leading to excess water accumulation on the coil. The overflow of water can cause water leaks. If you suspect that your air conditioner refrigerant levels are low, it is crucial to contact a certified technician to top it up for you.

Faulty Condenser Pump

A damaged or faulty condenser pump can also cause water leakage in your air conditioning unit. The condenser pump’s primary job is to remove the excess water from the evaporator coil and pump it outside the home. A malfunctioning pump can cause the water to accumulate and overflow, leading to water leaks. Replacing the condenser pump can be a quick fix for the problem.


A leaking air conditioner can indicate severe malfunctioning components or minor issues. While revising your air filter and cleaning your drain can be a quick fix for minor issues, always contact a certified technician if you suspect a bigger problem. Fixing issues beyond your expertise can lead to further problems and additional costs. Contact 303 Heat for air conditioning services in Thornton, CO.
