Where is the best place to put the exhaust in a whole-house exhaust ventilation system?
The house I am planning to put at least one 2,000+ cfm whole house exhaust fans is in zone 4B (hot and dry, Central Valley, near Fresno, California, but sometimes very humid and foggy in the winter months). Can the exhausted air go into the ventilated attic space or should it have a dedicated duct that goes through the roof? The house was built in the 1950s and remodeled with an additional den and an upper story with two bedrooms and a bath on the second story. It is about 2,700 square feet, counting both lower and upper levels.
