We have a Chrysler Airtemp A/C unit (more than 20 years old) that's gone on the fritz 2 days before we're scheduled to be away for 2 weeks. Although it's in the 80's outside, about 6 inches of frost has formed on the rubber-insulated tube next to the outside unit. There's condensation all along the line that runs through the basement to unit where the fan and the copper tubing are located. The latter is also covered with frost but is now melting since I've turned things off at thermostat. The fan will only work if it's set to manual. I've called a repairman and he's suppose to come tomorrow. In the meantime is there any way for me to determine on my own if this is a catastrophic breakdown that will require a new unit or if it's possible for me to do something on my own to get the thing going?
