Why does my car A/C not work on super hot days?

The time I need/want to use the air conditioner the most...it just blows out hot air?! It works fine on cooler days but on days when it's like 90+ degrees out it slowly will eventually just blow hot air. I don't understand why...what could be wrong? Thanks for your info!!!

    Does it cool when the engine is cool and you first start it? If not, open the hood and see if the compressor clutch is activated and the compressor is turning. If it isn't then there is a low pressure switch (usually mounted on the receiver/drier) that may be bad. You can unplug it and use a paper clip to jump the 2 terminals. If the AC turns on, then the switch is bad. If that doesn't work have the freon pressure checked using a gauge set. If the ac compressor runs when the engine is cold but not hot check to be sure the radiator cooling fan works (if it is an electric fan it should turn on anytime the AC is turned on). If it doesn't turn on with the AC switch turned on then more than likely the fan radiator fan motor is bad. Sometimes the engine temperature switch can be bad but if your instrument panel temp. gauge reads properly then the switch is okay.

    Your car A/C is not working at all even in cool days- That is just outside cool air you are getting not A/C air...........The problem is your car A/C is out of a/c gas. That only can be done with car mechanic. Weather is getting warmer so you will find plenty of coupon or deals that are offered by the neighborhood auto shop.
