Well dunno about the faulty component but for sure you only notice the aircon when it gets hot and you need it!!! I regas mine every 2 years and also change the filters, cos gradually you lose the cooling gas and so the system gets weaker and of course you only notice when the weather suddenly gets warm, Murphy ensures this!!!
