How does the condenced water that collects on the AC coil escape from the factory installed air conditioning unit? Does it have a drip tube that runs between the inner and outer shell? Or does it just run down the outside?
I just had to rebuild a high quality de-humidifier that had drip tube issues. It ran for a few days unattended dripping water before it was noticed. It got me thinking that a clogged AC drip tube could cause some problems
