Bathroom & Laundry Ventilation Fan Installation in Orange County, CA
Every bathroom in California is now required to have a ventilation fan — even if you have a window. O’Hagan Electric installs bathroom and laundry exhaust fans throughout Orange County, including new installations where no fan exists, replacements of noisy or weak units, and proper exterior venting to ensure moisture is actually removed from your home. We keep your bathrooms dry, mold-free, and code-compliant.
Why Choose O'Hagan Electric for Ventilation Fan Installation?
A bathroom fan installation involves electrical wiring, ceiling cutting, and ductwork routing to vent outside — not just into your attic. Our licensed electricians handle the complete installation: running power to the fan, cutting the ceiling opening, connecting ductwork to a roof or wall cap, and sealing everything against moisture intrusion. We also install fan/light combos, fan/heater combos, and humidity-sensing fans that turn on automatically when moisture levels rise.
Our Ventilation Fan Services
New Fan Installation
No existing fan? We install a complete exhaust fan system — electrical wiring, ceiling cutout, fan housing, and ductwork vented to the building exterior. We match the fan’s CFM rating to your bathroom’s square footage.
Fan Replacement & Upgrade
We replace noisy, weak, or broken fans with modern quiet units. Today’s fans are nearly silent (0.3-1.0 sone) compared to older rattling models, and much more effective at removing moisture.
Fan/Light & Fan/Heater Combos
We install combination units that provide ventilation plus lighting or heating in a single fixture. Great for bathrooms that need better illumination or a heat boost on cold mornings.
Humidity-Sensing Fans
These smart fans automatically turn on when humidity rises (during showers) and shut off when levels return to normal. No switch needed — they protect against mold 24/7 without any input from you.
How Ventilation Fan Installation Works
We make the process simple and stress-free:
- Assessment — We measure your bathroom, check attic access, and plan the ductwork route to the nearest exterior vent point.
- Electrical & Duct Prep — We run power to the fan location and install rigid or flex ductwork to a roof cap or wall vent.
- Fan Installation — We cut the ceiling opening, mount the fan housing, connect electrical and ductwork, and install the grille.
- Testing — We verify airflow, confirm the fan vents outside (not into the attic), and test the switch or humidity sensor.
Why Bathroom Ventilation Matters in Orange County
Even in Orange County’s dry climate, bathrooms generate significant moisture during showers and baths. Without proper ventilation, that moisture leads to mold growth, peeling paint, warped cabinets, and poor air quality. California code requires mechanical ventilation in all bathrooms regardless of whether a window is present. Proper exhaust fans protect your home’s structure and your family’s health.
