Has your car’s air conditioning system lost its efficiency in providing cool air? If so, it might be time to recharge its air condition system. But if you don’t want to rely on an auto ac service company, then doing it yourself can be done if you follow these steps.
Tools needed for AC recharge:
Step 1: Most auto ac service companies connect the manifold gauge to the AC system. To start, get your high-pressure gauge adaptor and connect it to the high-pressure port of the AC system and the low-pressure adaptor to the low-pressure port of the AC system.
Check whether the gauge shows any air pressure; if not, proceed to step 2.
Step 2:Connect your third manifold gauge adapter to the vacuum pump. Open the low and high-pressure gauges. Turn on your vacuum pump and open up the manifold valves when everything is connected.
Step 3: Turn off your vacuum pump and the manifold valves when you have reached 30 inches of mercury. Let it sit for an hour and ensure that the manifold gauge states that it is still around 30 inches of mercury. If it stays at 30, your ac system is fully sealed, and proceed to the next step.
Step 4: Use the nozzle to connect the refrigerant onto the manifold adapter and open the can to purge the system with a new refrigerant. Once done, turn on your car and check if it’s already cooling.
