Attic fans play a crucial role in maintaining a comfortable home environment by reducing heat buildup in the attic during summer. They work by expelling hot air and drawing in cooler outside air, which can help lower indoor temperatures and reduce the strain on your air conditioning system. Factors to consider include the type of fan, installation costs, and energy efficiency. Proper ventilation can also prevent moisture buildup, which can lead to mold and structural damage.
