Can you use flexible duct for bathroom fan? Yes, on a short, supported run. Measure the route and use rigid duct for long or bent paths.

Can bathroom fan and light be on same switch? Yes, if the control is rated for both loads. Compare one switch, a timer, and separate controls.

Bathroom exhaust fan duct size should match the exact fan manual. Measure the existing run, count bends, and reject a smaller hidden section.

Range hood duct size for replacement starts with the new model manual. Measure the old run, count elbows, and reject an undersized match.

Dryer runs but no heat? Use one five-minute test, split electric from gas, check airflow, and decide whether to call for repair or replace it.

Toilet phantom flushing after replacing flapper? Mark the tank level, check the refill hose, and let the stopping point name the next repair.

Sump pump not running during heavy rain? Use the rising water level to decide whether you have time for one dry-area check or need help now.

Bathroom fan condensation trap decisions depend on duct direction. Check insulation, slope, drainage, and stop lines before buying one.
