When a project includes multiple trades, they coordinate with others to deliver a smooth installation.
Hiring an electrician to install a bathroom exhaust fan offers these advantages:

Can I Hire a Handyperson to Install a Bathroom Exhaust Fan?
A handyperson is a good fit for straightforward swaps that do not require specialized electrical or HVAC expertise. They can mount the fan, connect to existing ductwork, and follow manufacturer instructions at a more affordable price point.
New wiring requires an electrician, and complex ductwork or airflow issues require an HVAC technician. When wiring and ducting are already in place and in good condition, hiring a handyperson is a budget-friendly choice. A general contractor can also coordinate finish work like wall repair and painting after installation. If you need help with installation and want to ensure the job is done right, you might want to consider an electrician near you for convenience and peace of mind.
How Do Pros Install a Bathroom Exhaust Fan?
Pros start by assessing what is in place and what needs updating, then complete wiring, ducting, and exterior venting to code. Here is how that process usually flows:
Assess bathroom needs, existing wiring, ductwork, and exterior vent path.
Determine proper fan placement for effective ventilation.
Mount the fan housing and connect it to power if wiring exists or coordinate new wiring.
Connect to existing ductwork or install and adjust ducting to vent outside.
Cut the exterior opening if needed and seal it carefully to prevent leaks and water damage.
Finish surfaces as needed and test for moisture and odor removal.
How Much Does Installing a Bathroom Exhaust Fan Cost?
Fan unit costs vary by features. A basic exhaust fan costs $15 to $80. A fan with a light costs $35 to $420. A fan with a light and heater costs $75 to $425. Adding a motion sensor light increases costs by $20 to $120. Your overall price depends on whether existing wiring and ductwork are in place or if you need new electrical work and exterior venting, which adds time and complexity.
