strange A/C noise

I used the a/c for the first time this year on my 2013 F250 and heard some noises I don't remember hearing before. When the a/c(or defrost) is on every 12 sec or so I hear a hissing sound that lasts for a couple of seconds then goes away. Is this the compressor cycling and if so is it normal to hear it inside the cab?

I know it has to do with the a/c because if I shut it off as the hissing sound is being made the sound will instantly stop. Other than the noise the a/c works fine and blows cold air.

Also, if it matters I have the standard control panel, not climate control.

Get the pressures checked to see if it has slightly discharged if it does not start acting like it did last year after a little more use.

You can always have your dealership inspect, fordman19762003. If you don't want to make a special trip, you can have your service tech check things out the next time you're in for an oil change. What's your truck's mileage?

Fordman19762003, I have that same hissing noise in my truck too, seems to do it anytime the a/c or defrost is on, and also about every 10 or 12 seconds.
I mentioned this to the dealer twice and they tell me it is just cycling and its normal, for some strange reason I'm finding that a little hard to believe.

Lately I've been leaving the radio off and you pick up a lot of "new" noises when it's so quite in the cab.

Mine has been doing that since I bought it. Its normal to hear a bit of hissing when turning the a/c on or off or defrost, but this is the first time hearing it cycle like that, other trucks I've owned last one being an'06 Super Duty never made that noise.
