How to recharge your car’s air conditioner with A/C Pro
If your car’s air conditioner is no longer cooling the air as it should, low refrigerant levels (due to a slow
leak) are usually the problem. This is especially a possibility if the air has gradually gotten warmer over a
few weeks or if you're turning your A/C back on after not using it over the winter. A can of A/C Pro will
recharge your system with refrigerant while also automatically sealing small leaks in the rubber gaskets
or hoses. It’s simple and anyone can do it in about 10–15 minutes, no additional tools required. Here’s
how:
Step-by-step instructions
Start your car and turn on the air conditioner to its maximum cool setting with the blower set to high.
Open the hood and look to see if the A/C compressor is running. It should cycle on and off; when
on, the center of the pulley will be spinning. The compressor has to be running before you can check the
refrigerant pressure. If it is not turning on at all, it is often because there is no refrigerant left in the
system; to check, proceed to step 7, add ½ can of refrigerant, and see if the compressor then turns on.
Locate the A/C system’s low-pressure service port. Two metal tubes come out of the A/C compressor;
the low-pressure port will be on the larger of those two tubes and is the only port on which the A/C Pro
hose will properly fit. You can check the online port locator on the A/C Pro website for help in finding
your low-pressure port. Remove the plastic cap from the port and save it, so you can put it back in place
when you are finished.
Unscrew the pressure gauge and hose from the top of the A/C Pro can, and then remove the red-andwhite plastic shipping disk from the can. Discard the shipping disk.
Attach the quick-connect fitting on the end of the recharge hose to your low-pressure service port.
Simply push the fitting onto the port until it clicks. Do NOT pull the trigger on the hose assembly until it
is attached to the A/C Pro can (in step 7), as that would allow refrigerant to leak out of the system.
When the compressor cycles on, check the refrigerant pressure with the gauge. To do so, rotate the
dial on the gauge until the center arrow in the “V” on the clear plastic lens points to the ambient
(outside) temperature (if temperature is between 85°-115°F, point the red arrow to 85°). If the needle
on the gauge is past the “V,” read step 2 and make sure the compressor is running. If the compressor is
running and the needle is in the red, do not attempt to recharge—contact A/C Pro support for help. If
the needle shows a pressure below the “V,” proceed to the next step to add refrigerant.
Pull the ring back to disconnect the recharge hose from the vehicle, and then screw the hose and gauge
assembly onto the top of the can. Shake the can well, and reattach the quick-connect fitting to the lowpressure service port. Squeeze the trigger to begin charging. While charging, rotate the can between the
12 o’clock (upright) and 3 o’clock (sideways) position every few seconds. Every 10–15 seconds, release
the trigger to check the pressure on the gauge. (The gauge will read “0” while the trigger is pulled.) The
system will be properly charged when the pressure is within the “V” on the dial, and your car’s vents are
once again blowing cold air. Do NOT overcharge the system by going above the “V” or past the green
zone on the gauge.
If it takes less than the full can of A/C Pro to recharge your system, simply leave the gauge and hose
on the can, disconnect the hose from the low-pressure port, and store the can in a cool, dry location. If
the can seems empty, hold it upside down and pull the trigger for one minute before disconnecting it
from the low-pressure port to make sure all of the product has been dispensed. You can then remove
and save the recharge hose for future use and discard the empty can. For California customers: Do NOT
discard the can, but rather, return it to the store for a deposit.
