[QUOTE="JayKay, post: 265626, member: 324"] Uhh, I could be wrong. It's actually likely. But shouldn't the attic fan be drawing air OUT of the attic? Is it possible that yours is wired in reverse? The air comes in along the eaves, and exits at the peak, or near the peak. The attic fan should be drawing air OUT, not in. The air in the attic should be the same temp as outside. Especially in the winter. That's why your ceiling is insulated, and not directly under the roof sheathing. If you've noticed, there are nearly always the tips of nails sticking into the attic, through the roof sheathing. If it's too warm in the attic in the winter, a frostball will develop on the tips of these nails. Melts, drips, insulation gets wet. Wet insulation sinks, loses r-value. Sounds like if the house is hard to cool and heat, there is not enough insulation in the attic. And yes, an attic fan is often controlled by a thermostat. Does nothing in the winter, but exhausts hot air in the summer. [/QUOTE]
