Handyman suggested cutting hole in 1330 sq. ft. attic for second attic ventilator. Does this make sense? (lemm.ee)

General info: Looking to get current attic ventilator fan replaced. The attic is about 1400 sq. ft. Current attic ventilation fan is a foot from the ridge of the roof. Live in USA.

Handyman wants: To install two 1500 CFM fans. Two 120 volt 20amp dedicated circuits, one for each fan. He wants to install the second fan 4 feet away from the current fan. He stated that the attic ventilator fan would need to be replaced within 6 years.

My questions: Would two fans be better than one fan? Would I need two 120 volt circuits to run two fans? Is there an attic ventilator that has a user replaceable fan?

Thank you in advance for any help.

Is it possible the 1500 cfm fans are intended to be run at lower capacity, and are just sized for a factor of safety?
