Is whole house fan equal to central air conditioning?

No, a whole house fan is not the same as central air conditioning. A whole house fan works by drawing in cooler outdoor air through open Windows and exhausting warmer indoor air, effectively ventilating the home. In contrast, central air conditioning uses a closed system to cool and dehumidify indoor air, circulating it through ductwork. While both can help regulate indoor temperatures, they operate on different principles and are used in different contexts.
