2013 Kelvinator high efficiency furnace. We moved our furnace and this one wouldnt work in the new space. Has had some new parts installed in the last couple yrs. New circuit board and pressure switches last year. Gas valve the year before and also have some spare parts to go with it. There is also 8x14 duct that will go with and the return duct. If you dont want the ductwork I can try and sell it separately. Would be a nice little shop unit. It is set up for Propane. The model number is in the pictures.
