![]() Many fans now come with LED light arrays for better efficiency, but using LED bulbs instead of incandescents in traditional sockets can also save energy-and money. Fan and light kits that earn the Energy Star label are 60 percent more efficient than those that don’t. You can eliminate most of the wobbling with such a kit. ![]() Most fans come with balancing kits, a combination of weights that you attach to the blades to make up for slight differences in blade weight, and removable clips that help you determine where to place the weights. Those often make more noise on the high setting than fans with smooth blades. Be wary of fans with large blades that have ridges, bumps, or other surface texture. Previous testing at CR showed comparable airspeed from fans rated from 5,000 to 5,600 CFM.įans with the most airflow also make the most noise-wind noise and fluttering, not necessarily motor noise. A higher number means more air movement, but don’t fret over small differences. Look at cubic feet per minute (CFM) numbers on the box or on the manufacturer or retailer website to get an idea of how well the ceiling fan moves air. (Don’t forget to turn off the fan when you leave the room fans cool you, not the room.) While the perfect indoor temperature may be a matter of family debate, you can experiment with your comfort level by setting the thermostat at, say, 78° F and going up or down from there.Īirflow and blade shape matter. ![]() Using a ceiling fan (which costs much less to run) can make you feel up to 4° F cooler, enabling you to set your thermostat a bit higher and still keep comfortable. According to Energy Star, you can save 3 to 5 percent on air-conditioning costs for each degree you raise your thermostat on a hot summer’s day. ![]()
