During the hot summer months, air conditioning systems become crucial to maintaining indoor comfort. However, if you notice your air conditioner leaking water or blowing warm air, it can cause concern. Leaks not only indicate a potential problem with your AC system, but they can also lead to further damage if left unaddressed. When this happens, you may wonder, “Why is my air conditioner leaking?” Technicians at Sasquatch Home Services are experts in HVAC maintenance in Victoria, BC, and the surrounding areas. We’ve compiled this list of various reasons why your air conditioner may be leaking, as well as potential solutions.

Clogged Condensate Drain Line

One of the most common reasons why an air conditioner is leaking water is a clogged condensate drain line. Over time, dirt, dust, and debris can accumulate in the drain line, obstructing the flow of condensed water. When this happens, the excess water can back up and leak out of the AC unit. To address this issue, try using a wet-dry vac to suction out the blockage or consult a professional technician for a thorough cleaning.

Broken Condensate Pump

Another reason why your air conditioner may be leaking is a broken condensate pump. Some air conditioning systems utilize a condensate pump to remove the condensed water from the unit. If the pump becomes damaged or malfunctions, it can result in a leaking air conditioner. In this case, the faulty pump may need to be repaired or replaced to restore proper drainage and prevent leaks.

Refrigerant Leaks

Refrigerant plays a crucial role in the cooling process of your AC system. If there is a refrigerant leak, it can cause the evaporator coil to freeze. When the frozen coil eventually thaws, it can lead to excess water that drips from the unit. AC repair to address refrigerant leaks requires the expertise of a professional HVAC technician, as they will need to locate and repair the leak before recharging the system.

Damaged Drain Pan

The drain pan, located beneath the evaporator coil, collects condensed water and directs it toward the drain line. However, water can leak if the drain pan becomes cracked or damaged. In this situation, replacing the damaged drain pan is typically necessary to resolve the issue.

Dirty Air Filter

A dirty air filter can impede proper airflow in your AC system, causing the evaporator coil to become excessively cold and freeze. When the frozen coil eventually thaws, it can lead to water leakage. Regularly replacing or cleaning your air filters can prevent this issue and maintain the efficient operation of your air conditioner.

Frozen Coils

Frozen coils can occur for various reasons, such as restricted airflow, low refrigerant levels, or a malfunctioning blower motor. When the coils freeze, they can create excess water that drips from the unit once they thaw. Therefore, it’s crucial to address the underlying cause of frozen coils to prevent further damage and restore proper functioning.

Aging or Inefficient AC System

Over time, air conditioning systems can experience wear and tear, leading to various issues, including leaks. If your AC unit is old or inefficient, it may be more prone to developing leaks. In such cases, AC repair may be required more often, so you may need to consider replacing the system to ensure optimal performance and prevent further water leakage.

We Can Inspect Your Leaky Air Conditioner

These are just some of the reasons why an air conditioner may be leaking. A leaking air conditioner is a sign that something is amiss within your central air system.
