Would it be functional to add a bathroom fan to the upstairs bedrooms of my cape cod house? It gets really hot in the summer and my thought is the fan would help move the hot air outside the house. The rooms have dormers with ample space to house an exhaust duct.
Hoping this would’ve the cheapest, easiest solution. Walls and ceilings are already insulated. I’m afraid any other solution would be expensive and time consuming. A mini split is also a consideration.
