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.

    First off, thank you for the advice.

    The reason the handyman gave for installing two fans was basic, to improve the dispersal of hot air. My partner and I concluded that removing heat would be the most effective first step to decreasing the temperature of the house, but we can be talked into considering insulation first. We’ll look into leak patching and into insulation.

    Do you happen to know if during the winter months, if insulation would significantly block the house from being heated by the sun? We are looking to get a heat pump in the long run and originally planned to have the insulation done at the same time, but in the meantime, winters can get cold here and any heat we get goes a long way.
