How to Recharge Car AC?

Is your car ac not blowing cold air as it should? You have probably run low on refrigerant in your car’s air conditioning system.

Over time, small volumes of the refrigerant leak from the lines, downgrading air conditioner performance.

To bring the air conditioner back to its utmost efficiency, you need to recharge it.

In this powerful guide, you will learn why is my car ac blowing hot air and how to recharge ac in the car in five simple steps.

How to Fix the Leakage before Recharging the Car AC System?

Many air conditioners drop their pressure due to leakage. Therefore, it’s critical to fix the leakage before recharging the AC. Find the leak by following these steps.

1. First, get a UV light and AC leak detection kit. The kit has gas with UV dye incorporated into it.
2. Pinpoint the refrigerant line with low pressure and connect the container with the UV dye gas to it.
3. Start the engine and activate the AC. Pull the container’s trigger to transfer some of the UV dye gas to the AC.
4. Move the vehicle to a dark area. Now, shine the UV light on AC’s all pipes and components.
5. If something glows in the dark, it shows that there’s a leak. You have to auto ac repair that part before recharging the air conditioner.

How to Recharge Portable AC for Car?

If you are wondering why my car ac blowing hot air, follow these steps to recharge it.

1. Purchase an AC Recharge Kit

Many vehicle part stores sell ac recharge kits for $40 to $60. Ensure “R134a” is written on the label because it’s the right refrigerant for modern automobiles.

The kit has a container of refrigerant and a hose that attaches to the car’s correct port.

It should also include a gauge to inform you when you have the right quantity of refrigerant in your vehicle.

If there is too low, it won’t work. If it is too much, additional issues and failures can take place.

2. Activate the Engine and Crank The Air Conditioner

To wholly recharge the ac, crank the lines wide open so that the refrigerant will fill all things it needs to fill.

Turn on the engine and set the ac system to MAX. Also, turn the blower to its maximum setting.

3. Attach the Kit to Low-Pressure Port

There are two main lines that transfer refrigerant through your car ac: a high-pressure line and a low-pressure line.

The kit links to a port on the low-pressure line for protection. Find the exact spot for your car, but normally it’s on a metal pipe that is easily reachable beneath the hood.

The recharge kit can only attach to a low-pressure port. It won’t connect to the high-pressure port, so try the other port if you can’t get it to attach.

4. Open The Valve And Recharge The AC In Car

Now, tighten the knob, break the container’s seal, and let the refrigerant flow into your ac system.

During the procedure, you may observe the car ac compressor engage, the engine running a little faster, and the engine fan start.

These signs indicate that the ac is filling with refrigerant and commencing to function properly again.

View the gauge, and keep recharging until the needle is in the green zone.

It means that the car air conditioning system is full but not overfilled. Close the valve and take out the hose from the port.

5. Check if the Cold Air Is Coming Out Of the AC Vents

Get into your vehicle and confirm that cold air is coming out of your ac system’s vents. If yes, then you are done.

If not, or if the cold air comes for a short period but stops again, look for an expert mechanic for car ac repair in Ontario, Canada.

Conclusion

If your car ac stops working when hot outside, you need to recharge it. By following the steps stated above, you can easily and quickly recharge ac in the car.
