How to know if gas is needed in the air conditioning of the car?

If you need to understand if you need gas in your car air conditioner you have come to the right place, as here we will tell you what are the primary warnings to locate any deficiency in the circuit.

There are no worries that air conditioning is essential for cars on this day, especially throughout the summer stage when high temperatures intimidate our peace and calm.

But if, due to lack of gas, the air conditioning system does not work as it should, thread the needle. And without wasting any more time, we will tell you here how to understand if you need gas in your car’s air conditioner.

Is your car air conditioner running out of gas? Here we will tell you how to detect it

When your car’s air conditioner runs out of gas, it may blow hot air like a fan. This is the primary sign that must be taken into account when there is a shortage of coolant in the car.

For their part since they have the possibility of there being many causes why the system suddenly stops cooling, but to understand for sure if we are talking about a gas leak you must always resort to a manometer

A manometer is an important gadget for measure the pressure of liquid and gases located in closed circuits. Pressures are measured with this instrument absolute or real with atmospheric pressure, achieving as a result manometric pressure.

What is really advisable is to attend a mechanical workshop to make this assessment. They have refrigeration professionals ready to do the work and locate if, due to insufficient gas, the air conditioner in the interlocutory does not cool.

How can the air conditioner be charged with gas?

After locating that the air conditioning circuit has run out of gas, the next step is to carry out charging. For this, take the following steps into account:

Step 1: Find system or circuit inputs

First of all, you have to find the entrances to the circuit, which are generally two pipes (high and low pressure), which have a cap that needs to be unscrewed.

The thinnest pipe is the high pressure and the widest is the low. If they are not in plain sight, the best thing to do is to look in the rules manual.

Step 2: Connect the machine to the circuit

Install the hoses to the low and high pressure sockets. The pressure of the gadget must initially mark values ​​between 8 and 10 bars.

But confirm before connecting to the circuit that the rest of the hoses are closed.

Step 3: Open passages for the gas to enter the circuit

If you have already verified that there is a good connection, the next step is to open the hoses to accept air intake. Of course, do it one by one and not both at the same time.

Open the hoses only until the marker goes up a few points. The intention is to avoid that the shell of the pipe breaks down and that the gas comes out of the hoses when disconnected.

Step 4: Recover gas and vacuum

This step lies in the rehabilitation of gas waste and in the execution of cleaning. Achieving this is a simple task as you just need to open the low and high pressure passages and press the green link on the gadget.

After self-cleaning, it is necessary to open the green valve to recover the gas. Once this development is completed the vacuum is carried out by time lapse of 20 minutes.

Step 5: Verify pressure

Check that the set markers, both low and high pressure, are at -1 bars. If the marker begins to rise little by little, it is likely that the gas leak persists.

If this is the situation, suspend the procedure and look at the circuit for the fault in order to carry out an effective gas refill.

Step 6: Recharge

Since the circuit is completely closed, it proceeds to the gas refill, which starts after tightening the red link of the machine.

Have on hand the exact amount the car needs, which you will find on a sticker on the engine.

Step 7: Verify that the air conditioner is working

Since you have finished recharging, close the valves and verify that the air conditioning is working properly.

In addition, you will need to close the hose passages. It is essential that you turn on the cooling system and place it at full capacity. If the air flow is strong and cools more, it means that the work gave excellent results.
