Unplug — Check around the house to see if devices are unnecessarily plugged in. Electronics and appliances are still drawing power even when they are off.

Maintain Your HVAC System —
Your heating and cooling system equipment runs best when properly maintained. Change your filters on a regular basis. Having your HVAC system serviced on an annual basis will ensure that your system is not costing you more than it should, as well as increasing the life of the system.
