What is one advantage of utilizing a whole-house fan?

One advantage of utilizing a whole-house fan is that it can help decrease air conditioning usage. A whole-house fan circulates air from outside through the house, effectively cooling it down by creating cross-ventilation, especially during the cooler parts of the day or evening. This natural cooling process can reduce the reliance on air conditioning, leading to lower energy costs and improved indoor air quality. By reducing the load on the air conditioning system, the whole-house fan not only creates a more pleasant living environment but also promotes energy efficiency.

The other options do not accurately reflect the utility or function of a whole-house fan. For instance, it does not eliminate the need for attic insulation, as insulation serves to prevent heat transfer and improve energy efficiency regardless of ventilation. Moreover, while whole-house fans can be quieter than some air conditioning units, they typically do produce some noise during operation, so the claim of silent operation is misleading. Lastly, whole-house fans cannot provide heating; they are primarily designed for ventilation and cooling purposes.
