Can I Still Use My Aircon If It Is Leaking?


An air conditioning unit is a vital home appliance, especially in tropical regions where the climate can be uncomfortably hot. However, a common problem faced by many homeowners is a leaking aircon. The big question that arises is, can I still use my aircon if it is leaking? The short answer is yes, you can, but it’s not advisable. Read on to understand why.

Understanding Aircon Leaks

Aircon leaks can occur due to various reasons, including blocked drain pipes, an improper installation, faulty parts, or even a refrigerant leak. A leaking aircon not only reduces the effectiveness of your unit, but it can also lead to bigger problems such as water damage, mould growth, and increased energy consumption if left unattended.

Implications of Using a Leaking Aircon

Energy Inefficiency

When your aircon is leaking, it needs to work harder to cool your home. This means more energy is consumed, leading to higher utility bills.

Potential Damage

Continuing to use a leaking aircon could result in water damage to your home or even cause the aircon unit itself to short circuit.

  • Mould and Mildew Growth: Prolonged exposure to moisture can lead to the growth of mould and mildew, posing a serious health risk.
  • Damaged Walls and Ceilings: Consistent leaks can damage the structure of your home, including walls and ceilings.
  • Decreased Lifespan of the Unit: Operating an aircon with a leak can shorten its lifespan and lead to costly replacements sooner.
