Estimated pricing
- Existing fan replacement
- $300–$600 per fan
- New-location installation
- $600–$1,100 per fan
Replacing an existing fan typically costs $300–$600, including connection to suitable existing ducting. Installing a fan in a new location typically costs $600–$1,100. Labor and materials are included; permit fees and sales tax are additional. Any additional ductwork needs will be discussed before installation.
New or additional ductwork is not included in either standard range. Any duct changes or additional ductwork must be discussed and agreed upon before installation. Exterior vent caps, roof penetrations, duct replacement and new duct runs are not included work.
Electrical work may require openings in walls or ceilings. Drywall patching, texture, and painting are not included and must be arranged with others.
Signs a fan needs attention
- Mirrors and windows stay fogged long after a shower.
- Mildew returns on ceilings, grout or around the window.
- The fan rattles, hums loudly, or runs without noticeably moving air.
- The fan has stopped completely, or the switch no longer controls it reliably.
- A laundry room stays humid or warm when the washer and dryer run.
Replacement or a new installation
A replacement fits a new fan at an existing fan location, reusing the existing wiring when it is suitable. A new installation adds a fan where none exists and needs a power source and a control.
Either way, the duct and exterior termination matter as much as the fan itself. A good fan connected to a crushed, disconnected or very long duct will still underperform.
Choosing a fan
Fan airflow is rated in cubic feet per minute (CFM) and noise in sones; a lower sone rating means a quieter fan. Room size, ceiling height and duct length guide sizing, and the manufacturer’s published ratings help compare models.
Humidity-sensing fans start automatically as moisture rises. Timer switches keep a fan running after you leave the room. Some fans include lights or night-lights; combination heater/fan units are a different, separately priced scope.
What True looks at
- The existing wiring and whether it can supply the new fan
- Box and housing size compared with the replacement model
- Attic or ceiling access above the fan
- The existing duct connection and where it ends
- The switch or control you want
