Saving on energy bill during extreme weather

Energy use usually skyrockets during weather events like high heat indexes. Experts recommend setting the thermostat as high as possible that is still comfortable and safe, using ceiling and floor fans and keeping shades and curtains closed.

Plus, they should avoid running heat-generating appliances, securely close doors and windows and replace HVAC filters if they are dirty.
