A ceiling-mounted whole house fan pulls cooler outdoor air in through open windows and exhausts hot indoor air up through the attic and roof vents, which can noticeably cool a home on mild Ohio evenings without running central air conditioning. Installation includes cutting the ceiling opening, mounting the fan, and wiring it to a switch or timer.

  • Installed in a central hallway or upstairs ceiling location
  • Wired to a wall switch or timer control
  • Can reduce reliance on AC during mild-weather evenings
