Specifically, we’re talking about the times when your aircon leaks. But don’t worry cause it is in fact avoidable.

If you’re about to go to bed and want to avoid nightmares, you might want to put off reading this until morning. If you’re about to get in the car, please read on.


Clogged evaporator drain

A clogged evaporator drain can cause aircon leaks. Make sure that the drain doesn’t have any sediments or debris to avoid leakage.


Damaged seals

Like all things, when we constantly use something, they usually get worn out. Seals that are too worn out can cause leakage. So make sure you also ask your service guy to check on it when you bring your car maintained.


Corroded evaporator core

When the core has too much rust, water will start to leak. As such, better avoid having rust to the corroded evaporator core to avoid any problems related to leakage. 


Why does my A/C have weak airflow?

There are a lot of factors that directly resonates to why you have a weak airflow and trust me, every car enthusiast feels your pain and discomfort. The sweat alone is enough to drive any of us crazy given the hot climate in the Philippines. If you notice reduced airflow early on—rather than later—take the right step and have it looked at before other fatal A/C system damage can occur.


Primary causes of weak airflow:

  • Mold or mildew may have accumulated in the evaporator core from residual moisture that occurs during the cooling process. When this happens, air will have trouble reaching your air vents.
  • Ventilation fan is fried. If the fan’s not blowing, air won’t be flowing very well.
  • A hose has come loose. This usually happens with the blower hose that supplies air to the blower unit.
  • Core case seals, blower house seals or evaporator core case seals; All can open up and diminish air flow. A/C ventilation systems are very sensitive and must remain sealed. Once they’re opened, the whole system is compromised.
