Do not sign any contract that requires full payment before satisfactory completion of a job. To save as much as hundreds of dollars a year on electricity, purchase energy-efficient appliances, especially air conditioners and furnaces. Energy efficiency information is found on Energy Guide labels required by federal law.
Many utility companies offer rebates for the purchase of energy-efficient products.
To save even more, purchase a programmable water heater timer and set it to turn on at off-peak hours. Other saving strategies include fixing running toilets, using low-flow showerheads and lawn sprinklers, and decreasing water heater temperature from 140 degrees to 120 or 125 degrees. Lower your thermostat. For each degree that a thermostat is lowered, heating bills will decrease by about two percent. Purchase a clock thermostat and set it to automatically reduce night time temperatures.
