I work maintenance at an apartment complex in northeast Wisconsin. Every winter when the temperature dips below 0 degrees, some of our unit furnaces are disrupted because of condensation ice that forms inside the concentric vent pipe. So far, our only solution has been to go up into the rafters and cut the pipe, then blow hot air up the pipe until the ice melts. Sometimes this can take hours. There must be a better way. Any ideas?
