Feel The LoveLennox Industries’ Feel the Love, Wisconsin, formerly Heat U.P. Wisconsin, seeks nominations for homeowners in need, as well as those who deserve recognition for their military or community service, to receive a free high-efficiency Lennox furnace. On the first Saturday of October each year Lanz Furnace & Fireplace is among about 70 participating Lennox dealers across Wisconsin and Upper Peninsula of Michigan who volunteer a day of labor and materials to install furnaces at no cost to the families. The project is supported by Lennox Industries, which donates up to 100 high-efficiency furnaces and Honeywell thermostats. All submissions are due by September 5th. Those received after that date will be considered for the following year’s program. For more information or to nominate a household, go to Or click below button.
