Furnace induced draft motor for homebrew mitigation?
My unfinished basement tested at just above 4 pCi/L. I only spend an hour or two a week down there depending on projects, but I'd still like to decrease that a bit.
There is absolutely no ventilation in the basement and the windows on the habitable floors are never ever opened. So I'm not surprised at the test results and probably a little ventilation will go a long way.
Since my furnace takes combustion air directly from the utility room in the unfinished basement and vents it outside, I'm thinking I could rig up a smart switch to run the induced draft motor only (independent of the furnace board) for just like a few hours a day. The furnace also happens to be near the worst source, the dirt crawl space.
Do you think this will have a meaningful impact? Seems worth a shot before doing more.
