Install electric ventilators and attic fans which remove hot air from an attic.
Seal all attic air leaks.
Of clearance above the fan.
Your vents can get clogged from dirt rust or insulation that was blown in from the attic.

These fans are commonly mounted in an upstairs stairwell or hallway ceiling where there s at least 3 ft.
There are probably many small air leaks in your attic space which can cause a major source of heat loss in many homes.
Attic ventilation fans are a type of attic fan that cools attics by pushing hot air outside while pulling in cooler air from soffit and gable vents.
