Frequently Asked Questions
What is a sone rating on a bathroom fan?
Sones measure fan noise level. A rating of 1.0 sone is very quiet — roughly equivalent to a refrigerator hum. Ratings of 0.3-0.5 are nearly silent. Older fans often run at 3-4 sones, which is noticeably loud. Upgrading to a quiet fan (1.0 sone or less) is a worthwhile comfort improvement.
How long does bathroom exhaust fan replacement take?
Replacing an exhaust fan in the same location typically takes 1-3 hours for an electrician. New duct runs or changing from ceiling to wall mount take longer. Adding a new fan where none existed requires new electrical and duct work — plan for half a day to a full day.
