i repeat: i'm not spending $50/month on electricity to run a dehumidifier to reverse the damage being caused by his a/c, and dry out all the p-traps at the same time, while making myself miserable.

it's his a/c, it's his foundation and it's ultimately his problem if his a/c ruins his foundation. i just want the smell dealt with.

all he has to do is turn the a/c off. really. it's that simple.
