Everything you need to know

In India, it is imperative that your car’s air conditioner works properly. The weather in the northern region of India is hot, while in the southern region it is humid. Once the air conditioner fails, people in both regions sweat profusely while driving. In India, repairing your car’s air conditioner is necessary during the summer and monsoon seasons.

The most common problem with car air conditioners is refrigerant leakage. Car air conditioner refilling is the ultimate solution to this problem. There are different types of refrigerants in the market and people are talking about it.

Refrigerant Type

• R134A – has been used in vehicles in many countries since the early 1990s

• Most vehicles in India use r134a

• R1234YF – This refrigerant has been used in vehicles since 2014. Most countries in North and South America use it.
• r12 – This is a very old refrigerant. It is used in older cars

The car air conditioning refilling process is quite time-consuming and also requires precision when handling refrigerant tanks and cylinders.

Before we get into the process, let’s first understand the tools and equipment required in the car air conditioning refilling process.

Required Equipment and Tools

This meter is used to measure low and high pressure refrigerant. In some modern automatic air conditioning filling machines, this meter is pre-installed along with the vacuum pump.

It is used to remove gases, vapors and other contaminants from refrigeration systems. Gas removal is very important for the air conditioning gas replenishment process.

• Manifold pressure gauge and vacuum pump adapter

These adapters connect the manifold gauge and vacuum pump to your car’s air conditioning compressor.

• Refrigeration oil (if necessary)

Refrigerant oil provides lubrication for the air conditioner compressor. This helps the refrigerant circulate through the system.

Key points to remember during car air conditioning refueling

1. The air conditioning gas refilling process should be carried out in a cool place, otherwise it will affect the results. This precaution is mentioned on the back of the refrigerant can.
2. When filling the air-conditioning gasoline, the front and rear doors of the vehicle should be kept open.
3. Always use the recommended type of refrigerant. This is in your car’s manual and under the hood of your car.
4. Do not overinflate.

Measuring outdoor temperature

If the outdoor temperature is low, do not try to refill. The temperature must be above 12 degrees Celsius. Gas refilling is done based on temperature and refrigerant pressure. Both must be at a balanced level.

Find the low side service port

The service port is located on the cooling system line connecting the accumulator and the compressor.

1. Clean the duct and surrounding surfaces. This will prevent accumulated dust from entering the cooling system when under pressure.
2. Connect the adapter with charging hose and hose to the low-pressure side service port.
3. Recharge the refrigerant to the optimum level, do not overcharge.
4. Carefully remove the charging hose.
5. Recheck for leaks or that the air conditioner is operating properly.

in conclusion

Car air conditioning refilling is done to avoid the car from running with low refrigerant levels during summer and rainy seasons. Car air conditioners often face leakage issues and hence need to be refilled. Air conditioning refilling can be done using some specialized manifold pressure gauges and air conditioning vacuum pumps. Different types of vehicles require different types of refrigerants. The process requires precision and caution. It is always recommended to have your car air conditioning refilled by an expert and take all the necessary precautions.
