With the coldest arctic blast of the season so far headed toward Minnesota, utilities are urging customers to turn down their thermostat at night and when they’re away.  Ross Corson with CenterPoint Energy:

“With a programmable thermostat, it’s easy to have your heating system work around your schedule… so that you’re saving as much energy and money as possible.”

Corson says be sure your furnace is inspected and tuned-up, and change the filter monthly at this time of year.  Use caulk or weather-stripping to seal leaks around doors, windows and other openings such as pipes or ducts.  And on sunny days keep curtains and blinds open to take advantage of the sun’s heat.
