I’ve figured out that about half of my yearly utility costs are because of heating & cooling. I live in an part that seems to be either hot & humid or chilly cold throughout the year. I maybe enjoy two or multiple weeks where I can turn off the oil furnace & a/c entirely. Because of the enormous expense of temperature control, I’ve gone to great lengths to eliminate waste. Since my lake house is older, there was a great deal of outside air getting inside through gaps & leaks when I first moved in. The windows were not slim or Energy Star rated. There was insufficient insulation in the walls, ceilings & crawl spaces. The air duct was in awful shape & required a thorough cleaning & sealing at the seams. The oil furnace & a/c were both in desperate need of professional repair. Because of all my efforts, I’ve significantly reduced yearly expenses & improved the overall comfort of the home. Just last Winter, however, I climbed up on a ladder to replace an overhead light bulb in the kitchen. I right away felt the rise in temperature & started to sweat. I realized that the heat from the oil furnace was rising straight up to the ceiling. This temperature stratification was affecting my budget & comfort. I did some research & invested in a bunch of ceiling fans. There is a sizable selection of styles & prices, & ceiling fans are fairly straightforward to install. I was able to install them on my own. The ceiling fans have paid for themselves in energy savings. The rotation of the fan blades pushes the heated air back toward the floor. This has allowed myself and others to lower the thermostat setting & reduce strain on the oil furnace. During the warm season, I reverse the rotation of the fan blades to push the heated air upward. The fans minimize the workload of the a/c & help to keep the air circulating.
