Here's a way to save time and energy when repairing floorboards. Instead of drilling and chiseling damaged floorboards, use a plunge router. First, use a magnetic nail finder to be sure there are no nails in the way. Set scribe lines across the damaged pieces. Then, run the router across the boards for a quick, clean cut.
During winter, a ceiling fan can move heat trapped near the ceiling back into the living area. This is especially valuable in rooms with high or vaulted ceilings. Remember to run your ceiling fan counter-clockwise in the summer and clockwise in the winter.
