Do fan/light combination units save energy?
Fan/light units labeled with the ENERGY STAR® logo (Figure 2) are about 50% more efficient than standard fan/light units. This can save you $15-$20 a year on utility bills (in addition to the heating and cooling savings gained by using the fan properly, as described earlier). Figure 2. Sample ENERGY STAR® logo for use on qualified products only. Lights can also be purchased separately as an add-on to a ceiling fan. Most fans accept add-on light kits, though a number of them are only compatible within brands. Check the package for compatibility information.
