What makes a fan work.

1

Vent outside

The duct must end at a roof or wall cap outdoors. A fan that blows into the attic just moves the moisture somewhere worse.

2

Short, smooth duct

Every metre of duct and every bend cuts the real airflow. A 4-inch smooth duct run beats crushed flex hose.

3

Quiet enough to use

Fans are rated in sones. Around 1 sone or less is quiet enough that people leave it running.

4

Runs long enough

About 20 minutes after a shower is a common rule. A timer or humidity switch does it for you.

Kitchens: a range hood that vents outside removes far more heat, steam and cooking smells than a recirculating one. Very powerful hoods can also need a make-up air supply under the building code — we'll check before you buy.

Homes

At home

Bathrooms with mould on the ceiling, fans that hum but barely pull, kitchens that smell for a day after cooking. We measure the airflow, fix or replace the fan, and duct it properly. California's energy code already requires bathroom exhaust in new homes.

Businesses

For businesses

Office restrooms, break rooms and staff kitchens — fans that run when they should and are quiet enough not to bother anyone.
