I am in the middle of a major remodel on a 1920s home in Northern California and need some advice on cooling. We are installing radiant floor heating and a gas stove for heat so this leaves us without an HVAC system. Our summers are mild days in the 80s some 100s but our nights cool off nicely. I really don't need air conditioning so I am now trying to decide if I should install a whole house fan or just an attic fan. Some people have told me that a whole house fan is noisy. Others tell me that an attic fan is all I need. I think I may need both. I'm thinking the whole house fan will draw in the cooler night air to cool the home and the attic fan will keep the attic temp down any time the temp gets to high.
