(Minneapolis Star-Tribune) Homeowners facing the prospect of a new furnace will soon have fewer and costlier choices.
The only options in Minnesota and 29 other Northern states will be furnaces with 90 percent efficiency or better, under new rules from the U.S. Department of Energy. Contractors won't be allowed to put in less-efficient models after May 1.
