The easiest way to tell on a R-134a system: The Low Pressure valve or Blue is on the big A/C Hose which gets cold. The high pressure or red, is on the smaller A/C hose which gets very hot!. NEVER recharge through the red service port. Pressure in excess of 200 psi are possible!!
The time it takes to recharge an air conditioning system can vary depending on the size of the system and the amount of refrigerant needed, but it typically takes around 1-2 hours.
I have a 97 Tahoe and it takes 5 quarts. That should be the same for you.
It takes the green Antifreeze
In the UK Kwik fit will do this for around £45 it usually takes around 30 minutes. If not your nearest Toyota dealer will do it.
The amount of time it takes to cool down a house after turning air conditioning on would be dependent upon a number of factors. Some of those factors include the size of the home, insulation and outdoor temperature.

With the filter it takes 6 quarts.
The best way is to use a coolant flush machine, as it takes fluid out, it puts back in the same amount. This way the system does not get air bound.
It takes 16 hours 46 minutes via I-80 E. Lake Tahoe and Thornton, Colorado are 1,078.7 miles apart.
The 2007 Tahoe takes just under 6 quarts. After an oil change add oil slowly and keep checking the dipstick until the engine is full.
A 1999 Ford Explorer takes R-134a The low pressure port is on top of the air conditioning system accumulator (can) which is located on the passenger side of the engine not too far from your electric motor for your heater/air conditioning fan. The valve is covered with a plastic dust cap.
