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.

Improving the insulation barrier between your ceiling and attic will only serve to increase your home's heat retention in the winter. When it's cold outside, the sun heating your attic is not going to increase the heat in your home more than the cold ambient temperature in your attic is going to decrease it. Before you pay to have this work done I'd genuinely consider whether there are other projects that would be much more impactful you could do instead. Definitely get other opinions from contractors first (never just get one quote for any project, prices and recommendations can vary widely) and see if you can get a certified home performance contractor to take a look at your goals
