Welcome to 2 hours help.

Up to 48 hours trouble shooting and coaching on repairs $38 additional if you approve it at that time.

Can you tell me the full model number of the AC unit, and the size of the room, and about any south or west facing glass?

If you do not have the model number tell me how wide and tall the AC unit is and if it plugs into 120 volt outlet or a 240 volt outlet.

We can go from there.

Thanks, ***** ***** is the room and how much south and west facing glass does it have? The larger the room, and the more window area the larger the AC must be.

I need that data in order to help you.

I need to know also about how old the AC is and if it is plugged into a regular 120 volt outlet or not.

I don't know . it has cooled up til this point

Expert:  Phil replied 2 years ago.

In that case, there are either air leaks letting hot and moist air into the room that did not exist before, or the inside and outside coils on the unit are dirty and need to be cleaned. If cleaning the coils does not work and the room is not leaking air... then the unit might have a refrigerant leak and not working to its full capacity.
