Why is my AirCon Leaking?

Dealing with Leaking Air Conditioners: Common Causes and Solutions

One issue that almost every air conditioning user encounters at some point is a leaking air conditioner. Leaks are not only annoying and inconvenient, but they can also pose safety risks. Understanding the common causes of leaks can help in preventing and addressing them effectively.

Common Causes of Air Conditioner Leaks:

  1. Blocked Condensate Line: The primary culprit behind most air conditioner leaks is a physical blockage in the condensate line. This can occur due to:
    • Poor Maintenance: Systems that aren't cleaned regularly or properly can accumulate biofilms, slime or debris in the condensate pan and line. Pests like rodents, geckos, and cockroaches can also cause blockages by leaving behind eggs or chewed internal packing material.
    • Contaminated Coils: Heavily contaminated coils can lead to tracking and leaking issues.
  2. Low Refrigerant/Gas: A system low on refrigerant can cause ice to form on the coils. When the system detects ice, it may initiate a defrost cycle, resulting in excess moisture and intermittent dripping.
  3. Stress Fractures in Condensate Pans: Over time, the natural vibration of the system, especially if poorly maintained, can cause plastic or polycarbonate parts to deteriorate. This can lead to hairline cracks in the condensate pan, causing small but persistent drips.
  4. Environmental Factors: Air conditioners are designed to operate in sealed environments. If a door or window is left open, the system works harder to remove the additional moisture from outside, leading to increased running costs, inefficient cooling and excess moisture on the indoor evaporator. This can cause sweating and dripping on the surface.
  5. Poor Installation: Incorrect installation can sometimes result in improperly placed condensate lines, leading to leaks that may require costly corrections.

For most leaking air conditioners, a Sanitair Premium Clean can resolve the issue in 9 out of 10 cases. Professional cleaning helps clear blockages, improve efficiency and extend the lifespan of the system. However, it's important to note that while regular maintenance significantly reduces the risk of leaks, it doesn't guarantee immunity from all potential issues due to factors like poor installation or environmental conditions.
