My carrier air conditioner is 7 years old. It has puron not freon. It is always on and usually keeps a constant temperature. Yesterday I had a crowd at my house, the doors were opening all the time and the air conditioning could not keep up and keep the house cool. I kept setting the thermostat lower. Today I had it set at 73 but it is 78 and the unit is leaking. Any suggestions? I turned it off because I thought it could have frozen up since it was working so hard. Thanks for any suggestions.

If you are leaking water from the inside unit your condensate drain is clogged. Open panel up and run a wire or the like where it exits the drain pan
