I have a bathroom exhaust fan I installed in the basement to vent out
the cat litter smell. I let this fan run 24/7. I'm debating if I
should put it on a timer to only run a few hours a day. My question
is, how much is it probably costing me a year in electricity to run
the fan all day and all night as I have been? I understand rates vary
by area, I'm just looking for a ballpark idea.
