I bought this 6,000 BTU TCL AC unit last year out of the box. I noticed it leaking last year and didn't think anything of it. Now it is leaking again this year and I see a small hole in the bottom of the AC unit.
TCL says online that they shouldn't have a drain hole: https://support.tcl.com/ca-appliances-common-questions/my-window-air-conditioner-not-draining but it seems to be excessively leaking and dripping rust-colored water down the siding of my house.
Does this seem incorrect? Should I replace it?
