Expanded lines of G61MP gas furnaces are 95 percent AFUE. The gas furnace is Energy Star®-qualified, featuring efficient two-stage operation, providing more even temperatures throughout a home, says the company. A two-stage furnace runs at low stage more than 80 percent of the time providing a quiet, consistent flow of heat. The Duralok Plus® heat exchanger, stainless steel secondary heat exchanger, and steel cabinet ensure durable performance, while the SureLight® control board and nitride igniter provide reliable, efficient operation. For even greater fuel efficiency, the G61’s dual-fuel capacity allows it to be paired with an electric heat pump. It’s backed with a limited lifetime heat exchanger warranty and a five-year limited warranty on all remaining covered components. Other options include the G61V with variable-speed technology and the Dave Lennox Signature® Collection G71MPP gas furnace with Precise Comfort™ technology that provides the ultimate in customized climate control.
