Quick fan story...
Pete is fanatical (ha! get it?! I'm so lame) about making sure the bathroom exhaust fan is running whenever someone is taking a shower. The fan then must remain on until the bathroom is no longer steamy. Even though a fan deprives me of the steamy bathroom showers that I love, I accept that I have to do what is better for my house over my personal showering preference.
While redoing the bathroom over at the beach condo Pete gets up on the ladder to take out the old vent fan and install the fancy new light/vent unit. With the new combo unit if the overhead light is on, the fan will be on.
Pete takes down the fan. And realizes that since 1984 the fan has been venting to nowhere. It was just a fan and motor that made whhr sounds attached to our ceiling. A quick peek into the shared attic area confirmed that not one other unit had a vented bathroom fan. The builder was a corner cutter.
No wonder I liked taking showers there.
Now the new fan/light actually vents. My Husband, the not corner cutting fanatical fan installer.
