How To Put Air Conditioner Coolant In A Car
The most expensive item on your electric bill in hot summer areas is the cost of running the central air conditioner. If your unit does not have the correct amount of refrigerant, these costs can be even higher. Here are some steps to help you charge your central air conditioner at home.

If you need to charge an air conditioner at home, it is best to have the job done by a licensed professional. If you want to proceed on your own, turn off your air conditioner and then connect the pipes from the pressure gauge manifold to your system’s pressure pumps. Turn on the air conditioner and let it run for at least 15 minutes. Then connect the supply hose from your manifold to the refrigerant tank. Make sure the container is in an upright position. Add the coolant slowly and allow the system to stabilize for 5-10 minutes. When the air conditioner has completed one cycle, turn off the unit and remove the gauges. Read on to know what kind of charging ports you need! If the vehicle is more than 6-8 years old and the cooling effect of the air conditioning system has deteriorated over time, there is a good chance that this is due to lack of coolant in the system.
A while ago I drained the coolant in my Polo’s air conditioning system. The cooling effect of the air conditioner in my car is noticeably reduced and I feel it during my daily commute. A strange noise was heard from the vents that were not behind. I decided to read more about how to fill refrigerant in car air conditioning systems and it is very easy to refill the refrigerant when the system is low and there are no problems with other components of the system and restoring the cooling. performance For your reference, we provide a dedicated and detailed DIY thread for our repository.
When the problem occurred, I did a quick check of all relevant components of the HVAC system:
Air Conditioning Low Pressure Port
A lack of coolant in the system can lead to inadequate cooling. Although these are fully sealed systems, the coolant level will decrease over time as the rubber seals/O-rings in the rubber hose and metal pipe fittings wear and coolant gradually leaks out over time. If there is a hole in the pipes or metal pipes or in the condenser coil from a violent rockfall, the refrigerant will flow back. Sometimes the Schrader valves in the car’s charging ports leak a very small amount of gas. However, if the car is older than 6 to 8 years and the cooling effect of the air conditioning system has deteriorated over time, it is more likely due to lack of coolant in the system. As in my case. In all my years, I have never refilled an air conditioner refrigerant. But I don’t know if there are any leaks in the system at this point.
The type and amount of refrigerant used in the vehicle is indicated on a sticker in the engine compartment or on the hood.
The AC manifold assembly is used to fill or evacuate refrigerant from the system and to measure the pressure on the low pressure (LP) and high pressure (HP) lines. It has a brass manifold with two pressure gauges – one marked blue (marked 0-220 psi) for the low pressure side and one marked red (marked 0-500 psi) for the high pressure side.
A valve is mounted on both sides of the manifold that controls the flow of coolant through three threaded connections. When you add refrigerant, a valve near the LP side opens and refrigerant flows in liquid phase from the refrigerant can (stored at high pressure like your LPG bottle) into the system (low pressure LP side). The distributor has a sight glass in the center that shows the flow of coolant as it fills the structure.
Signs That Your Air Conditioner Has Too Much Refrigerant
Color coded hoses are used to connect distributors to the system. As with pressure gauges, blue for LP side, red for HP side and yellow for loading or displacement. Color codes are used for easy identification – otherwise the hoses are identical in terms of connections and size.
Schrader valves are threaded at the ends as these tubes are in tires. Pressing the central pin releases the gas.
For connecting hoses to the vehicle’s LP and HD ports, quick-connect fittings are included. These are also color coded – blue for the LP side and red for the HP side.
Since the openings are different, quick couplings are very easy. Quick Coupler LP has a smaller opening while Quick Coupler HP has a larger opening. You cannot attach a wrong attachment to a contact.

These quick connectors attach to the charging ports in the car just like the LPG cylinder regulators we have at home.
When charging the system, the yellow pipe is connected to the coolant can through a screw valve. The valve has a pointed tip:
Turn the valve clockwise and it will puncture the can. Open the valve counterclockwise and the coolant will escape. Be very careful to make sure the valve is open before connecting to the can. Otherwise the can will be punctured and the refrigerant will leak!
When recovering refrigerant or applying vacuum to the system, the yellow pipe is connected to the recovery unit or vacuum pump. Replacement of compressor coil/condenser/evaporator coil/pipes or leaking pipes requires evacuation of refrigerant from the system.
What Type Of Refrigerant Does My Car Need?
To turn off the pipes when they are not in use. This prevents dirt and dust from entering the pipes.
I got a manifold kit for Rs 2300 with pipes and quick connectors. The good thing is that I can physically check the parts and their quality unlike online shopping. Plus, the repair shop agreed to replace a part if it leaked, otherwise there was no warranty. Additionally, the same setup can be used to charge the refrigerant in a home air conditioner with the correct refrigerant; Not that I plan to do that now, but it’s good to know it’s possible with the same kit.
Even when the valves in the distribution unit are closed, the reading is shown on the gauges as these valves control the flow of refrigerant from the center port to the LP or HP ports.
Depending on this temperature, the LP gauge should read between 45 and 50 psi and the HP gauge should read between 190 and 230 psi according to the reference table. The LP gauge reading is OK, but as the HP gauge shows, the reading is 135 psi, which is low and indicates insufficient coolant flow on the high pressure side/discharge.

The yellow tube now contains the ambient air + refrigerant mixture. Air/moisture is not good for the system and should be removed from the line before charging. Carefully loosen the yellow hose connector at the end of the manifold to remove air from the hose until some refrigerant comes out.
Observe the flow of liquid phase refrigerant through the sight glass in the manifold:
Close the valve. Do not pour all the coolant from the can into the system at once!
Excess coolant does more harm than good – it impairs cooling performance and damages the compressor, valves and seals. Be careful not to open the LP valve completely suddenly!

If you still have problems, you may want to find a good air conditioning service repair shop/technician – unlike other auto repair shops, these people can quickly diagnose an air-related problem and suggest the appropriate course of action in less time. . I could have done this too, but I preferred to do it alone to get to know the process and learn from it.
