There is barely any feeling that can compare to enjoying the chills of fresh air in your car while driving through the harshest weather conditions. This is why most modern car designs now come with inbuilt air conditioning systems. Indeed, the benefits of having your car AC in top condition at all times are numerous. However, to achieve this, you must take proper care of the AC system and maintain it adequately.
One of the maintenance steps you need to take for your car AC system is to recharge its refrigerant from time to time. Doing this will help it to stay in top condition and serve you for longer. Adding more refrigerant to your car AC when due can help keep the car cool in sunny weather conditions. It can also help the AC system to last and serve you for a longer time. This article will offer some tips to help you recharge your Car AC quite seamlessly.
When your car’s air conditioning system stops blowing cool air and starts to lose power, then it is time to consider an AC recharge. The steps listed below will help you do this effectively.
What Does AC Recharge Mean?
AC recharge simply entails adding extra refrigerants to your car’s air conditioning system. This is done so that the AC can start blowing chilly air again.
It is important to note that, in some cases, recharging your AC system might just be a temporary fix to a bigger issue in the system. In such cases, it is best advised to invite a professional mechanic to help you check out and fix the problem.
Quick Steps for Recharging Your Car AC
- Step One: Start Your Car Engine
Start your car engine and turn up your AC to High or Max
- Step Two: Confirm if the AC Compressor is Engaging
A compressor entails a device in the AC system that functions to transform the refrigerant from liquid to gas. It has a clutch that is supposed to spin with the accessory belt anytime the AC is on Max.
If this clutch is engaging, then the AC’s refrigerant is probably low. In this case, it is best to go ahead and test the pressure before you add the refrigerant.
If the compressor clutch is not engaging, then the AC system is low on refrigerant, the compressor has failed, or there is an electrical problem. In this case, invite a professional mechanic to help you diagnose the problem.
- Step Three: Test the AC Pressure
You can test the AC pressure by switching off the vehicle engine. After that, find the low side pressure port. Often, You can locate this port on the passenger side of the engine bay.
Step Four: Attach the Recharge Hose on the Port
After locating the low side pressure, attach the recharge hose to it by placing the end with the quick-connect fitting over the port and firmly pushing it down until it clicks into place.
- Step Five: Monitor the AC Gauge
At this point, turn your AC to the highest settings and restart your car. Monitor the gauge by watching out for the compressor to engage the clutch. You want the reading to be very close to 40 psi once the compressor is engaged.
- Step Six: Thread the refrigerant on the recharge hose.
Thread the can of refrigerant on the hose at this point. This will make it easier for you to top off liquid refrigerant into the AC system slowly. After installing the can, hold it upright and squeeze the trigger for about 10 seconds, so the refrigerant is added to the AC. After that, check the pressure gauge to ensure you have not overcharged it.
- Step Seven: Go Back Inside Your Car and Test the Temperature.
Insert a thermometer in an AC vent near the steering and check out the temperature. The temperature should be around 28 degrees cold if the AC has been fully charged.
If you followed all the above-listed steps, then congratulations. You just recharged your car’s AC system.
