Aircon Losing Cold Air

My car is a 2010 Altis. For the past three days I have noticed that the cold air has been reduced. This car is my daily driver and my temperature is always set at 24C so I know how cold it is supposed to feel like. When I tried to feel the air coming out of the blower, it is really not cold enough, Today was very rainy and cold yet the car did not feel that much cold as it should be. I did not even need to use the defogger. Normally, in weather like this, I would need to use the defogger after a few minutes because it gets really cold.

In the past, I already claimed warranty from the Casa thrice from problems with the Auto Climate (it can't sense the correct climate? ) I am not sure if this could be connected. But then again, with the Auto Climate problem it was the blower setting that's the problem. This time it's the air that's being blown out that is not cold enough.

I am at a dilemma on whether I should have this repaired by the casa because my car's warranty period just ended. I am not sure if I could argue this as a backjob :grin: Is there a reputable AC shop where I could bring my car? I am afraid to mess up whatever settings the car has that is why I am more comfortable with the casa. But then again if it will cost me more than double, then I will just risk having it repaired some place else. Out of warranty na rin naman e.

Thanks in advance
