EDISON - Furnaces across the state are working overtime this week, and so are home heating companies trying to fix the ones that couldn't take the pressure.

The 27-year-old furnace in Bill Stephens' father's home went out Monday, just as temperatures in New Jersey were plunging to record lows.

"This weather has put a tremendous impact on our staff," says Michael Iarrapino, of Edison Heating and Cooling. "We're trying to make everybody warm and comfortable, and it's been a task."

The company's owner says they received more than 10 service calls per hour Tuesday morning. Getting to them was made even more difficult when some of its vehicles wouldn't start in the cold.

Iarrapino says their work isn't over as the bitter cold lingers in the state.
