Question

My window unit AC stinks VERY bad. What do I do and how?

Answer 1

Clean the filter and replace it if necessary, could be dry rotted. There should be a drain to drain off the condensation, make sure it is clear and clean.  

Answer 2

If it smells moldy or somewhat like a pond, turn it off, take the back cover off & wash it out with bleach water.  Make sure that where it is at that it is tilted so it drains water outside.  You need to make sure it doesn't puddle inside the unit.

Answer 3

YA IT HAS A FILTER,BUT DONT THIK THATS THE PROBLEM,PULL THE UNIT OUT OF THE HOUSING AND CLEAN THE COILS AND THE GUNK OUT OF THE INSIDE,MAKE SURE YOU DONT HAVE ANYTHING DEAD INSIDE OF IT.

Answer 4

Does it have a filter you can replace?

Answer 5

Vinegar and a hose.  

Answer 6

Wash it down and go get an algaecide tablet at an HVAC store to kill the mold that is likely growing in it.
