Here’s a simpler version:
What I’ve done:
1st try: I tried to fill it up. After that, I felt cold air coming from the vents and heard a hissing noise. Then the AC started blowing hot air.
2nd try: I tried to fill it up again, but it didn’t work.
NB: The AC has never worked since I bought it.
The lines are not good. Also, if you overfill it, you could ruin everything. It should only have about a pound and a half inside.
I used an AutoZone fill kit both times.
The first time, I don’t think I used it all.
Never ever ever ever use them at all.
What’s wrong with my ac???
A line is broken, the AC pump is bad, and it could be anything else too.
