help!!!!

I have a 2000 honda accord lx been having trouble with the ac first it was missing freon add two bottles then it does blow cold air only when the car temo is cold once its normal the ac kicks every three seconds and cuts off when i am in a stop go.city it blows stale air but when im on highway it blows cold air. Also three times i heard a pressure leak but still after that the car still blows air stale in stop and go and cold air in highway. Can anyone tell might be.

Little hard to make out what all is happening there.

I kinda suspect what you think is a pressure leak is actually a vacuum leak that's making the blend door misbehave and giving you the different air under different situations.

Also if you added 134a without gauges, good chance you're overfilled. Two is a lot for that system unless it's empty.

My mechanic said that condenser is bend but.not that much plus at the time of my friend he put.two cans of.freon and my mechanic said did he vacuum the air.out i said no.well he said that another problem so what i did.is press the vaule where u.put freon and press it with the ac off and.hold it until.i.felt the air.wet rightnow.the air.is working fine.

OK if you didn't evacuate the system before charging that explains a lot....air in the system expands way too much and makes pressures go higher...which will make it cycle and probably make the expansion valve and other components make noise that may be the hissing you heard. By relieving the overcharge it's probably now in a state where it can work well enough now without cycling when system temps and pressures rise...

But you really should vac it down, that will get rid of any air and moisture in the system, and refill with the correct amount of refrigerant charge, as stated on the A/C info label on the radiator support...that will assure you're not running so high pressure that you blow a hose, and you aren't fulla moisture that's gonna destroy the compressor and the cores from the inside out....once a compressor goes from internal corrosion, it'll shotgun the whole system with metal, and you'll have to replace it as well as the receiver/dryer, expansion valve, etc....
