2009 Honda Accord 3.5 A/C blowing hot air all of a sudden?

I was driving around the other day and out of nowhere my ac went from ice cold to warm air, in a span of 10 seconds. The vents then made a hissing noise. I tried adding some Freon and nothing happened, except a loud hissing noise. Is this some type of leak or did some component break?


With the help of my dad, we found out that it was the ac condenser, only cost me about $55 to replace. Getting ice cold A/C now in warm Texas.

    Evaporator could be leaking.  See a mechanic and get the AC system leak checked.  If the evaporator is leaking, it will be an expensive repair.

    A loud hissing noise is usually a sign of a leak

    • It was a condenser leak, I fixed it and have very cold ac now, thanks
