Reem Air Conditioner Blows hard for a few hours then nearly stops

Hi, we have an older Reem Air conditioner and when I first turn it on it will blow fairly cold and hard but it will gradually stop blowing, after 4 hours it is hardly blowing at all, but it blows cold the whole time. I have noticed that the evaporating coil is very wet, it may be too wet, not sure how wet it is supposed to be, please respond if anyone has any ideas. Thanks.

Are you sure that the evap coil is not freezing up when you notice less air flow?

I haven't checked it when it slows down and stops, only when it has been turned off, I will check though, I kind of doubt it because it doesn't blow that cool, in fact it doesn't blow as cold as it used to. What would cause it to freeze up? Am I hurting anything by running it with a problem? Thanks.

Low refrigerant, low air flow, or refrigernat metering device problem will all cause it to freeze up. It actually works the opposite you think it would. When a refrigerant system gets low on charge it will cause the coil to freeze up and will not cool as well as it should.

Just checked and it is frozen solid with ice, you were exactly right, now how am I going to fix it, it is most likely low freon but not for sure.

The fix is to call a pro. If it is low then there is a leak! Don't just have it filled up and expect it to last.
