The Lennox ML297VK is the top-efficiency model in the Lennox Merit® Series gas furnace lineup, rated at up to 97% AFUE. It combines two-stage gas valve operation with a variable-speed ECM blower motor — delivering high-efficiency condensing performance at the most accessible price point in the Lennox 97% AFUE lineup. For Chicago homeowners who want near-Signature-Series efficiency without the Signature-Series price, the ML297VK is the right choice.
At 97% AFUE, the ML297VK converts 97 cents of every dollar of natural gas into usable heat. Its two-stage gas valve runs at low fire during mild weather and full fire when outdoor temperatures demand it, reducing short-cycling and improving humidity control. The variable-speed ECM blower motor delivers precise airflow at lower energy consumption than standard PSC motors.
D's Air & Heating, Inc. installs the ML297VK throughout Chicago and the surrounding suburbs. Every installation includes a free Manual J heat load calculation, City of Chicago mechanical permit, city inspection coordination, and Lennox 10-Year Parts Warranty registration. Call (773) 940-0965 to schedule your free in-home estimate.
