A whole house fan pulls cool evening air through open windows and exhausts hot attic air, cutting air conditioning use on the mild Bay Area evenings that follow hot days. At Site Electric Services, we wire and install whole house fans with properly sized circuits and switching.
We proudly serve Vallejo, Benicia, Napa, Fairfield, Concord, Martinez, and surrounding areas with expert-level service that's built on experience, honesty, and an unmatched reputation for quality.
For most homes here, yes — our warm days and cool evenings are ideal for a whole house fan, which pulls in cool night air and pushes hot attic air out, often cutting down significantly on AC use. It works best in homes with good attic ventilation.
Whole house fan installation involves mounting the fan unit in the attic or ceiling, wiring a dedicated switched circuit, and often adding attic ventilation to handle the increased airflow. The electrical side requires the right wire gauge and, for larger or multi-speed units, a compatible switch or timer control.
We also check your attic's existing ventilation, since a whole house fan needs enough exhaust venting to move air efficiently without straining the motor.
Our focus is on residential electrical work done right the first time, not rushed patch jobs. We bring an unmatched level of care and expertise to each job, with a reputation built on referrals, repeat business, and integrity.
We start by discussing your cooling goals and where the fan will be installed.
Our electricians assess your attic ventilation, panel capacity, and the best wiring path for the fan.
We explain your options in plain language and provide an accurate, upfront estimate before any work begins.
Most whole house fan installations are completed in a single visit.
A whole house fan without adequate attic exhaust venting can strain the motor and struggle to move air efficiently — we check ventilation before installing so the fan actually performs as expected.

Whether you own a historic home in Benicia, a mid-century house in Vallejo, or a new construction in Napa, we have the knowledge and tools to get your whole house fan installed safely and up to code.

Often, yes. A whole house fan needs enough attic vent area to exhaust the air it's pulling through the house — if your attic is under-vented, we may recommend adding vents alongside the fan so it performs the way it should.
Price can range depending on fan size, ceiling access, and whether additional attic ventilation is needed, but for a typical 2,000 square foot home, material and labor together run around $2,500.
Most whole house fans do need a dedicated circuit sized to the fan motor, especially larger units. We size the circuit based on the specific fan being installed.
An attic exhaust fan only moves air within the attic to cool that space. A whole house fan pulls air through the entire living space and out through the attic, actively cooling the rooms you live in, not just the attic above them.
Yes — most modern whole house fans support timer controls, multi-speed switches, or smart/app-based controls, which we can wire in as part of the installation.
