Attic Fan
Attic ventilation for Valley summers
A closed attic in Woodland Hills in July can sit thirty to fifty degrees above outdoor temperature. That heat radiates down through the ceiling all evening, which is why upstairs rooms stay warm long after sunset.
An attic fan only works if intake air can reach it. We look at eave and soffit venting first — a powered fan with no intake pulls conditioned air out of your house instead of hot air out of the attic.
Typical timeline
Most attic fan installations take a single day. Adding intake venting or a whole-house fan can extend it to two.

What's included
The scope, in plain terms
Ventilation assessment
Measuring existing intake and exhaust venting against the attic area, and finding the blocked or painted-over vents that are common in older homes.
Powered attic fans
Roof-mounted and gable-mounted fans, sized to the space, installed and flashed so the roof stays watertight.
Solar-powered options
Solar attic fans where roof orientation suits them, running without adding to the electrical load.
Whole-house fans
Ceiling-mounted whole-house fans that pull cool evening air through the house and push hot air out the attic.
Intake venting
Adding or clearing eave, soffit and static vents, and installing baffles so insulation isn't smothering the intake path.
Controls
Thermostats and humidistats so the fan runs when the attic actually needs it rather than around the clock.
Questions
What homeowners ask about attic fan
Does an attic fan really help?+
It helps when intake ventilation is adequate and the attic is well insulated. Without those, it can pull air-conditioned air out of the living space. That's why we check the whole system before installing one.
Attic fan or whole-house fan?+
An attic fan cools the attic. A whole-house fan cools the house by pulling in cool evening air. They solve different problems, and some homes benefit from both.
Will it leak where it goes through the roof?+
Not when it's flashed correctly, which is a roofing detail more than an electrical one — and we do the roofing work ourselves.
