The cost to install a kitchen exhaust fan is around $300.00 to $400.00 for the labor charges.
Then there's also the cost of the kitchen exhaust fan itself.
A simple kitchen exhaust fan may cost around $50.00 while an over the range exhaust fan hood can cost around $80.00 to $300.00 or more depending on the type of range hood you buy.
You can install the kitchen exhaust fan or range hood yourself if you're handing and do so for only the cost of your time and the cost of the exhaust fan.
However if you need someone to do the job then you can expect to pay around $65.00 to $100.00 per hour to install the kitchen exhaust fan.
Installing a kitchen exhaust fan requires around 3 to 4 hours of work.
It depends on the type of kitchen exhaust fan you want installed as to how long it will take to install the kitchen exhaust fan.
Sometimes additional holes will be required and sometimes you may already have the existing hole.
If the vent hole is already existing then there won't be as much work required to install the kitchen exhaust fan.
But if the hole is not there then a hole will need to be cut into the wall or ceiling to exhaust the exhaust fan and that requires additional work and time.
