A: Lowering your electric bill may require several steps, including a change in potentially costly habits. Be sure to turn off all lights, lamps, ceiling fans, and electrical devices not in use when leaving a room. Install a timer for all of your exterior lights. Try keeping your thermostat set so your HVAC system runs for shorter periods, ultimately reducing the amount of electricity consumed. Lastly, you can also set your thermostat slightly lower in the winter and higher in the summer to reduce HVAC operating time chances.
