This unit is essentially brand new as it was never hooked up. Comes with window fitters, manual, all hoses, and filter and multifunction remote. This unit will heat or provide air conditioning. Also has a dehumidifier mode. The 14,000 BTU capacity is massive and keeps you very cool or warm depending on what you want. The fan is nice and quiet and it has many modes including an energy-saving mode. The Unit is nice and small as well. Easy to put in a corner or store if needed. This was over $600 new.
