Even with a perfectly tight ceiling, powered attic ventilators use more energy than they save.

When should I run my attic fan?

A whole-house fan is usually installed on the attic floor near the center of your house. In the late evening or early morning, the fan is turned on to exhaust hot air from the house. Cooler outdoor air enters through open windows, lowering the indoor temperature.

Attic Fan Ventilation However, if your attic has blocked soffit vents and is not well-sealed from the rest of the house, attic fans will suck cool conditioned air up out of the house and into the attic. This will use more energy and make your air conditioner work harder, which will increase your summer utility bill.

Why did my attic fan stopped working?

Electrical Issue Your attic fan may not be turning on because of an electrical problem like a tripped circuit breaker, a blown fuse, or a bad connection. You can diagnose it by plugging other electrical appliances that are working into the same outlet and by plugging the fan into a different power outlet.

How do I remove heat from my attic?

What humidity should attic fan be set at?

In summer, the thermostat operates the fan when the attic temperature reaches a preset level (usually 90 to 95 degrees F). In winter, the humidistat operates the attic fan when the relative humidity exceeds a preset level (usually 40 to 50%). This reduces attic moisture.
