Low cfm similar to a bathroom vent 300cfm and only in the hot spots basically by adding an inline ducting fan to the return ducts for the hotspot rooms.

High temperatures inside your attic shorten the life span of shingles.
They have thermostats that turn the fan on at a recommended preset temperature of 100 110 degrees.
Attics are known for their ability to heat so rapidly and leave you feeling breathless.
Whether your home is old or young updated or outdated your attic ventilation could most likely be improved.
