Installing bathroom fan without attic access
Is there a way to install a bathroom exhaust fan without attic access? The electrician who installed mine 20 years ago only screwed the housing to the edge of the ceiling drywall. No, I'm not kidding. I'm afraid to remove it to explore the situation in case I can't get it back in again. I can't imagine how it can be attached to the joists. The house is a split level and the attic area is over the bedroom level and contains blown cellulose insulation. There is no access to it. No, I'm not kidding about that, either. The code may have changed since the house was built 40 years ago, but apparently wasn't in existence back then.
