The Lennox ML180VK is an 80% AFUE variable-speed gas furnace in the Lennox Merit® Series. It combines the simplicity and lower installed cost of an 80% AFUE furnace with the comfort benefits of a variable-speed ECM blower motor — delivering quieter operation, better humidity control, and improved air distribution compared to standard PSC motor furnaces.
Available in five capacity configurations from 30,000 to 110,000 BTU, the ML180VK is an excellent choice for Chicago homes where a condensing furnace is not feasible but improved comfort is desired. Its variable-speed blower operates at lower speeds during mild weather, reducing noise and energy consumption.
D's Air & Heating, Inc. installs the ML180VK throughout Chicago and the surrounding suburbs. Every installation includes a free Manual J heat load calculation, City of Chicago mechanical permit, and Lennox 10-Year Parts Warranty registration.
