I will find something tall enough to reach it and check the vent first thing tomorrow morning. We've only had that AC duct on maybe less than 5 times I think in all the time we've lived here since it doesn't cool our house down when it's on. And even though the management says there's nothing wrong with it, it still doesn't keep the house cool in the summer's. We just use the fans and window AC's to cool the place down that we bought. If the smell is coming from the AC, I don't know if they'd do anything about it since they charged us last time we had them come out for our AC
