Okay, so my AC went out yesterday. I called a handyman today and he supposedly fixed it. I know he changed the connector for the AC and re-filled the freeon. The unit is about 8 years old.
In any case, the temperature was in triple digits all day today in Dallas, and is 91 degrees right now. My thermostat is set at 72 degrees (i have a digital one so I know exactly what temp to set it to).
However, the temperature keeps hovering around 76-75 degrees. The unit has been running for about 12 hours now, and it still hasn't cooled down to 72 degrees. Like I said, the temp right now is 92 degrees outside. Do you think it's a problem with my unit or is this expected?

wwwstat -- Thanks for your response. Yes, it was working perfectly before. The connector (on the side panel on the outside unit) he showed me was a little rusted. It was a black piece about 5x5 inches with lots of scews on it that u affixed the wires to.
The original problem was that the AC tried to start yesterday all day, and make a loud noise like a loud BEEERP and couldn't start at all.
I am not sure how the freon went away or what this guy did, but he said that we were running low. Maybe I never noticed before...or maybe he ripped us off.

would your ac cool your home down to that temp the day before it quit working? if it did it wouldn't need freon..what happened that it quit suddenly...was it the contactor that he changed instead of the connector...I need more information about how good or bad your unit worked before it quit...then i can give you a more informed answer most units if they are large enough for your home should be able to drop the temp in your home 18 to 25 degrees cooler than the outside temp...especially if it is well insulated and you have energy star doors and double pane or thermal pane windows....................................................................................................................................(2ND part of answer).............................................................................................................................................................................................that sounds like it could be the contactor,,,,,if it was cooling good it would only need to have freon addded if it was freezing up ...now if it has to much freon it will not cool properly neither and there is a possibility that the larger of the two lines is frosting over close to and on your compressor...I would call this guy and tell him that my unit was cooling better before he worked on it than it is now except for the fact that it wouldnt start when You called him...he is responsible to come back and fix it...

Handy men are not always so handy. AC units can be tricky. I recommend that you make sure everything is clean. A rusty conduit fitting does not cause the AC unit to run weird. Maybe he added refrigerant when it didn't need any. That can cause major problems up to and including compressor failure. Too much refrigerant can cause excessive head pressures, liquid flooding the compressor, high suction pressure, and liquid refrigerant washing the oil out of the crankcase.
Sometimes units just do not have enough capacity to cool a house to 72° when the temp is over 100°. That doesn't mean it needs refrigerant or that anything is wrong at all. I recommend that you do not call a handy man unless he specializes in refrigeration and air conditioning. Adding refrigerant is not the answer most of the time. It can do more harm than good. Refrigerant is not fuel and AC units do not "USE" refrigerant like gasoline. Refrigerant should never be added unless there is a leak. In that case federal law requires that the leak be found and repaired before adding refrigerant.
I recommend that you make sure that outdoor coil is very clean and that the fins are not smashed in. Change the filter in your air handler inside. I don't know how the guy determined to add refrigerant, but you might want to have it checked by a professional. Some refrigerant may need to be removed now.
DIRT DIRT DIRT is the main enemy of an air conditioning system. You might be amazed how much of an improvement you will see after you thoroughly clean your air conditioner. Save yourself a lot of money and clean your air conditioner yourself at least twice a year. Then you won't have to call a hany man when it's 105°.

Hard to say. If the house was warmer than usual then it will take some time for the AC to catch up. Mine went out last week and it took it about 16 hours to catch up and shut off. My AC unit is also a little larger than it needs to be, so depending on the size of your unit, that may be right. Give it another day to catch up, if it still is high then call another repairman. good luck.

It seems your Ac was not fully vacumed before filleing freeon, another reason might be that it wasnt filled with freeon upto desired pressure.
