Selling a used Lennox natural gas furnace, removed as part of a heat pump conversion (upgrading to ductless heat pump — nothing wrong with the furnace itself). Ran fine right up until removal.

Specs: Model: ML180UH090P36B-55 | Serial: 1718J45494 Input: 88,000 BTU/h | Output: 71,000 BTU/h (0-2000 ft rating) 80% AFUE, single-stage, natural gas 1/3 HP blower motor, 120V Upflow configuration Fasco inducer motor + Honeywell gas valve included AHRI Certified

Condition: Used, fully functional at time of removal — not a failed unit. Cabinet has normal wear/light surface rust on a couple panels (see photos), no damage to burners, heat exchanger, or inducer assembly. As-is, no warranty — recommend having an HVAC tech verify/service before install.

Good for: Budget replacement, rental property, cabin, or DIY install
