The system will produce excessively high pressure which could damage fittings and components, and you'll get insufficient cooling from the AC system.

Can you over load a auto with freon air was cool before now blowing hot?
You can overcharge the a/c system. This causes too much head pressure in the compressor hendering it from cooling. Usually when you overcharge, it damages o-rings and seals in the system causing it to lose freon and a/c oil.
The high side pressure on your auto ac is reading over 400 psi when the ac is on what could be the cause?
A defective fan control, broken fan belt, dirty or blocked condenser coil, incorrect refrigerant, refrigerant overcharge and also the fact that the car is not moving and the hood is open while you are checking it causes the ac system to lose the benefit of the airflow it would normally have by forward movement. 400 psig is way too high.

How do you recharge the AC in a 1999 GMC Yukon?
Buy a recharge kit from an auto parts store. This will include a charging valve/hose, and cans of freon. It's best to get a charge hose with a pressure gauge on it. Screw can onto tap end of the charging hose, turn piercing valve clockwise until it stops. Attach quick connector to the low side outlet of the AC system (this fitting is foolproof. It will only fit on the correct connector). Turn vehicle on, turn AC on MAX with fan on high. Go back to the charging hose and turn the piercing valve counter clockwise to let the freon out of the can and into the hose, into the AC system. Make sure AC clutch is cycling to ensure movement of freon into the AC system. Do not overcharge the system, or you may burst parts. Most systems only hold 2 cans worth. To achieve best results, you must evacuate the entire AC system of all freon & pressure before charging.
