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.
