It will cost you more in electricity and in filters. Running the fans is basically recirculating the air throughout your house. It will possibly make it colder depending on where the draws are located. If they are downstairs it will more likely push the cold air from downstairs upstairs (given the fact that hot air rises). In the summer it is smarter because you are evenly distributing the air upward.

Should I leave the fan switch on my thermostat set to fan rather than auto?
If a user clicks on New from a document library then a word template opens with metadata in the header section, will the SPServices jQuery cascading dropdowns work in the word's header? I doubt it. If not, can I force user to fill out the metadata first when they click on new then open the word template in the word and it should be filled as user already filled the metadata?
