How long does it take for AC Pro to work?
All in, prepping, measuring, and recharging the system took me about 30 minutes. However, the Corolla's pressure levels were exceptionally low and I took more time than I probably needed to measure air temperatures and take photos, so it's still a fairly quick fix. via
What happens if you put too much refrigerant in car?
If it's overcharged, the decompression from liquid into gas can't occur so your compressor is squirting out liquid coolant instead of gas coolant. The results will be a noticeable sound as your AC compressor struggles to pump everything through the lines. via
How many cans of freon is 3 pounds?
3 Lbs would be 48oz......... 4 cans. The refrigerant is measured in weight, not fluid ounces. via
Will car AC work if overcharged?
Overcharged car ac can lead to some pretty serious repairs down the road if left alone. Additionally this can actually cause your whole ac system to fail as it can also damage the ac condenser. While this is uncommon it does happen. The condenser takes the refrigerant in it's gas form and pulls the heat away from it. via
Can you overcharge AC system?
A refrigerant overcharge alters the pressure inside the air conditioner and puts the compressor in danger. The Compressor: Excess refrigerant creates a danger called slugging. This is when extra refrigerant floods into the piston cylinders of the compressor when in a liquid state. via
What are the symptoms of an overcharged AC system?
4 Signs Of An Overcharged Air Conditioning System
Will AutoZone put Freon in my car?
Or, if you'd like to tackle the job yourself, AutoZone has all the tools and refrigerant to service your R-134A or R-12 vehicle. via
What PSI should I recharge my AC to?
Low Pressure and High Pressure Readings
If you are using a low pressure gauge when the low pressure reading is between 25 psi and 40 psi, the system is fully charged. For a high pressure gauge when the high pressure reading is 200 to 225 psi for R12 or 225 to 250 psi for 134a, the system is fully charged. via

When should you not use AC Pro?
Is AC Pro bad for your car?
Mixing refrigerant types is never a good idea, and can cause unintended consequences. In fact, the resulting mixture is so volatile it could damage the equipment used in professional A/C service -- and many auto shops will refuse to work on cars that have had the wrong refrigerant put in. via
Are DIY AC recharge kits bad for your car?
DIY A/C Charging Does Not Evacuate Old Refrigerant. The reason your car's A/C system needs to be recharged is that, over time, the refrigerant gas that makes the system work will leak out of the system. This can lead to overcharging the system, which can cause significant damage. via
Can too much Freon make car AC not work?
The air compressor for the A/C unit may not operate correctly when the system is overfilled with refrigerant. This can actually cause the car itself to run roughly or even die in some cases. via
Will overcharged AC freeze up?
If the system is overcharged, part of the refrigerant cannot be evaporated, and the compressor will work with the refrigerant in liquid phase. It means that if the system is undercharged with refrigerant, the suction and discharge pressures are below the levels required for efficient operation. via
How do you overcharge an AC discharge? (video)
How do you know if freon is empty?
How much is a pound of 134a?
In order to get the price per pound let's do some simple math: $150 / 30lb cylinder = $5.00 per pound. via

When recharging with a charging station or with a 30lb cylinder and an electronic scale, you need to add 2oz to the system capacity specification. via
How do I know if my car AC needs recharging?
What happens if AC pressure is too high?
When the pressure of the AC system is too high this might indicate a leakage or diminishing amount of refrigerant, both of which require immediate attention. If the AC temperatures are abnormally warm, this could indicate an issue with the compressor that might need repair or replacement. via
What temperature should my car AC be blowing?
Temperature should be 40 to 42 deg F. Higher fan speeds, resulting in high air volume, will result in higher vent temps. Rear cabin systems are normally 10 degrees warmer because they have a larger volume of space to cool. via
