How Does A Cars Air Conditioning System Work
The air conditioning systems most cars have are consist of outdoor and indoor units that turn a refrigerant into liquid and utilize it to create cool air.
The compressor that is located in the outdoor unit of the AC system applies pressure to the refrigerant in order to turn it from a gas into a liquid. Once the refrigerant becomes liquid it is moved to the evaporator coil or the cooling compartment where its temperature is reduced.
Afterward, the refrigerant returns to its original gaseous state and it is dispersed by a fan that is a part of the systems indoor unit.
Consequently, the entire system cannot function properly if there is too much or too little refrigerant in it, which is why you must check its cooling capabilities on a regular basis.

Connect The Dispenser To The Fill Port
You must stick to the instructions closely while attaching the dispenser to the fill port, and try to complete the entire process as quickly as possible. The first thing you will need to do is get a firm hold of the dispensers connector and then lift its outer sleeve.
Squeeze the trigger to remove all traces of air from the hose that connects the dispenser to the fill port and then push the connector to the fill port while still squeezing the trigger and holding the connectors sleeve.
Pressing the trigger ensures that an even flow of the refrigerant is coming out of the connector which reduced the chances of air or moisture reaching your cars AC system.
As soon as you release the sleeve the connector should fall in place, and then proceed to release the trigger. Double-check if the connector is correctly positioned on the fill port before you start recharging the AC system.

How To Get A Compressor To Engage
Reading the pressure of the AC system isnt possible if the compressor isnt engaged. In case the middle part of the pulley that is attached to the compressor isnt moving when you start the engine, you should try adding half of the refrigerant can.
If the issue persists after you added fresh refrigerant to the system, you must take your car to the mechanic.

How Do You Detect And Repair Leaks In The Air Conditioning Unit
Create a solution of water and dish soap and decant this into a spray bottle. Open the hood of your car and spray this solution over the air conditioning unit. You should ensure that the entire unit is covered in a film of your solution to make sure that you dont miss any leaks.
Once you have sprayed, watch the surface of the air conditioner. If there are any leaks present, you should begin to see some bubbles forming. This works following the same principle as when you are checking bike tires for a puncture.
If the bubbles that you can see are infrequent and slow to form, this indicates that your leak is small. If the bubbles appear to be foaming then the leak is likely to be large. This will often require professional assistance to repair.
If you have small leaks then you can use a recharge kit that contains a sealant. Try to look out for products that say the sealant is a conditioner. This ensures that it will not clog the pipes of your cars engine if the sealant is gooey then it will build up and cause blockages.

How To Choose The Right Refrigerant For Your Car
Before knowing how to put freon in-car air conditioner, you should know what type of refrigerant you should add to your car. There are only three types of refrigerants that can be added to your car. The right fit refrigerant for your car will depend on your cars manufacturer. All cars that are made before 1994 use the R-134 refrigerant. Proper freon was banned since then as it is very harmful to the environment. Vehicles made after 1994 uses the R-134a refrigerant that is less flammable and more environment-friendly than R-134.

What Is An A/c Recharge
During a car A/C recharge, your A/C system’s old refrigerant is evacuated and replaced with new refrigerant to help ensure your air conditioning system is operating properly and keeping you comfortable.
At Firestone Complete Auto Care, our A/C recharge service starts with the Firestone A/C Performance Check, wherein one of our experienced tire and auto service professionals:
- Visually inspects all A/C components
- Runs a performance test
- Performs a system state of charge test
- Performs a system control test
- Performs a leak test using an approved electronic leak detector
What Is A Recharge
Generally, when you bring in your car for an AC recharge, the technician will start by checking system pressures with his gauges. If the system is just a little low, he can start looking for leaks right away. If the system is too low or completely empty, refrigerant will have to be added to look for the leak. And once he finds it, hell have to evacuate the system and repair the leak before he can refill it.
So, a full AC recharge involves evacuating the old refrigerant, and then refilling it with fresh. Otherwise the technician has no way to determine if the correct amount is on board. If the system has been opened, or any components are changed, theres an additional step. Theyll need to vacuum the system of all atmospheric air and moisture before charging it. Needless to say, this all takes a few hours, much longer than simply draining in a can of refrigerant without any diagnostics.

How Do I Know If My Car Ac Needs Recharging
In order to know when your car AC needs to be recharge, these are three most significant signs:
Air Conditioner Clutch wont Engage
Usually when the air conditioner reaches its maximum capacity, the clutch engaging starts to click and drivers can hear it very well. The reason for this is that the clutch engages with the AC pressure switchs signal in order to read the level of system pressure. For this purpose, when AC reaches low level, the pressure switch cannot activate, leading to no clutch engaging. This problem stops the system from circulating.
Cooling capability Decreases
One of the most famous symptoms that tells you the automobiles needs recharging is that the overall cooling capability dramatically drops. Why is this a clear signal? Since the system of air conditioning works by circulating a pressurized refrigerant, if the air is not blowing cold air at all, you need to charge your AC fast.
Signs of Refrigerant Leaks
Last but not least, there will be signs of refrigerant leakage. There will be greasy film on many AC fittings or components underneath the automobiles. If there is any, this might be a sign that you need to recharge your AC.

Add Air Conditioning To Your Old Car Its Easy
It used to be that one of the first things you’d trash from your performance car was the air conditioning system, assuming your car had it, of course. It’s understandable, too, because the parts for most A/C systems were huge and heavy: big cast iron compressors, massive condensers, and evaporators big enough to keep an industrial meat locker cold. Such isn’t the case any more. In the past decade or so, those heavy parts have been replaced with small, light aluminum compressors, compact lines, and more efficient heat exchangers. Better still, the compressors don’t rob power from your engine the way the older units did, and the stuff is so good, many race cars like the Pratt and Miller built C6R and C75 Corvettes that compete endurance races like the 24 Hours of LeMans have air conditioning to keep the drivers and interior electronic components reasonably cool. So why not take advantage of some of this technology and add air conditioning to your older car? We followed along as Hot Rod Garage co-host, Lucky Costa, installed this Vintage Air underdash system in his 1966 Fury Wagon, and were impressed with how easy the job was.

What Does Recharging Ac In A Car Mean
Recharging is replacing refrigerant that’s leaked out of the car’s air conditioning unit. If your vehicle’s AC has low pressure and is blowing warm air, it means there is a leak because it is a sealed system.
An R-134a refrigerant leak allows entry of moisture and air, which can damage the AC compressor when combined with the refrigerant.

Locate The Low Pressure Side Refrigerant Fill Port
1. Pop the hood.2. Locate the refrigerant fill port on the low pressure side of the system. This will have a small plastic lid with an L printed on the top. Unscrew this cap to reveal the port.Where is the fill port? For most vehicles, the low pressure side fill port is located on the left side of the engine bay. It will often be a small section of metal pipe that has two lengths of rubber hose coming off either end. Look to the back of the engine bay called the firewall. Protruding from the firewall should be two pipes or hoses next to one another, one larger than the other. Follow the larger hose to find the low pressure side fill port. The photos depict the location of the fill port on two different late model engines.DANGER! Do not touch anything you are unfamiliar with. Almost everything in the engine bay moves and/or gets hot. The high pressure side hoses get very hot, do not touch them. It is okay to touch the low pressure side hoses, they should be around ambient temperature.
