Question: got the crud out of the AC drain pipe w/ shop vac & it is draining well now. but noticed that the foam around the pipe leading into the outdoor Carrier condensing unit is wet for about 3-4 inches (not frozen) & pipe remains wet (not frozen) inside the condensing unit. do i have a problem here? foam is dry as it enters the AC unit sitting on top of the Carrier furnace. is it ok to run the AC? what needs to be checked? thanks, darc
