Don’t.
For both environmental and health reasons, the U.S. Environmental Protection Agency (EPA) advises against replenishing Freon or refrigerant on your own. Legally, only EPA-licensed technicians are permitted to recover Freon.
R-22 in particular from earlier Freon formulations is no longer in use, but it is readily accessible online. Only older A/C units use these older formulas, but if you lack the proper knowledge, you risk using the incorrect one.
Any activity involving A/C Freon must be documented and submitted to the EPA so they can keep track of it. To avoid environmental release, all Freon must be adequately recovered and recycled. For these purposes, the EPA has approved particular equipment.

My automobile can I install freon at AutoZone?
Check out our list of recommended stores in your neighborhood for assistance if you need assistance with this or any other AC recharge or service. Alternatively, AutoZone has all the equipment and refrigerant necessary to service your R-134A or R-12 car if you choose to handle the work on your own.
How can I tell whether the AC in my car lacks freon?
If the air coming from your air conditioner is warm or at room temperature, this is one of the most clear signs that you have low Freon levels. As we previously covered, this compressed refrigerant is circulated to power the air conditioning system in your car. Performance eventually suffers when the amount is too low.
How much freon can a 2019 Nissan Altima handle?
From the 2019 model year, some of Nissan’s vehicles marketed in North America started using the new R-1234yf refrigerant instead of R-134a.
In my car, where do I place the freon?
Remove the hood.
2. Find the refrigerant fill port on the system’s low pressure side. A little plastic lid with a L printed on the top will be attached to this. To access the port, unscrew this lid.
The low pressure side fill port is often found on the left side of the engine bay on most cars. It frequently takes the form of a short metal pipe with two lengths of rubber hose emerging from either end. Look at the “firewall” at the back of the engine compartment. There should be two pipes or hoses sticking out from the firewall, one bigger than the other. The low pressure side fill port can be located by following the longer hose. The photographs show where the fill port is on two various late-model engines.
DANGER! Never handle anything you’ve never handled before. Nearly everything in the engine bay is in motion or becomes warm. Do not touch the high pressure side’s tiny pipes; they become quite hot. The low pressure side hoses can be touched, and they should be at room temperature.
How can I check my car’s freon levels?
It might be upsetting to discover that your air conditioner isn’t functioning properly. If you think the heat may be to blame, it’s a good idea to check the refrigerant level before visiting a mechanic.
You need the following to check the refrigerant:
- Thermometer
- AC meter
- security glasses
When you have your materials:
- Once the pressures have stabilized, check the gauges. Between 25 and 45 psi should be read on the low port, and between 250 and 400 psi on the high port. You most likely have low refrigerant levels if both are low.
- Examine the air conditioner. Visit the mechanic as soon as you notice any worn-out parts or loose clamps.
- Once connected, turn on your vehicle’s air conditioner and, if it has one, adjust the temperature to the lowest level while using the recirculating air function.
- If the temperature on the thermometer is 40F or less than the outside temperature, your air conditioning is operating as it should.
- Both the high-pressure service port and the low-pressure service port should be equipped with gauges. Between the accumulator and compressor on the passenger side of the firewall is the low port. The high port is located on the firewall’s line that connects the condenser and evaporator. Refer to your owners handbook if you are unable to locate the ports.
- Put the thermometer in the vehicle’s center vent, and then let it run for a while.
If you do decide to visit the technician, make the most of your waiting time by negotiating a deal with Jerry on your auto insurance.

How many Freon cans can a Nissan Maxima handle?
You are at the proper level, and the correct amount is two cans. 23 ounces is correct according to my review of the FSM. It uses PAG46 oil on our automobile. PAG100 may be present in some pre-mixed freon.
Does introducing freon require that the automobile be in motion?
It could be time to add extra freon if the air conditioner in your car is not cooling properly. If yours breaks down, adding freon yourself might be worth a shot to avoid the lengthy waits and expensive costs of contacting a professional.
Freon is a refrigerant that cools the air in air conditioners. It is a gas that has been compressed into a liquid and then discharged to assist in cooling the air conditioner. You can use your air conditioner in the summer thanks to this procedure.
There are numerous different refrigerants, but R-134a freon is the one used in automotive air conditioners. When it’s hot outside, this kind of gas will assist keep the temperature inside your car cool. Unfortunately, if you discover that your system is no longer keeping you cool, this can be expensive to replace.
The addition of freon requires operating your car because it is done through a canister. Holding this canister underneath your vehicle will allow you to spray it into the outside air conditioning system.
Reasons to Keep Your Car Running
When adding freon, you should use your car’s operating engine and air conditioning because:
- The freon will change into a gas too quickly if the air conditioner’s lines are opened while the engine is off, resulting in poor engine performance or engine failure.
- The freon can circulate more quickly while the car’s engine is running and the air conditioner is turned up high.
- The A/C should be operating while you add the freon so you can keep an eye on how much you are adding.
- Modern air conditioners in most cars contain electronics that, if the refrigerant is not moving at a high pace, could be damaged by the freon.
Make sure not to add too much freon when carrying out this step. It is advised to err on the side of caution when adding freon because overfilling your system might result in pressure build-up and harm to your engine.
You must read the directions on the freon can before installing it in your car, just like with any other task. When recharging, pay great attention to the safety instructions provided and make sure you abide by them at all times.
How long does it take to fill a car with freon?
Recharging the car’s air conditioning requires roughly 45 to 60 minutes to completely drain the old gas and replenish with new refrigerant.
How long does a car’s freon last?
Regardless of the weather, maintaining your car’s air conditioning at its best may be accomplished by understanding the freon gas life cycle and when to replace it.
Your car’s AC freon gas can last five years with the right upkeep and care. If you frequently use your automobile on long travels, that number might be lower.
A automobile should be regassed every one to two years, according to auto AC professionals. By doing this, you can reduce your risk of experiencing compressor problems, refrigerant leaks, and clogged filters.
What occurs if the Freon level is low?
The Freon charge should not change as it cycles between the liquid and gaseous stages; rather, it should stay constant. Freon does not break down, however leaks can cause its level to drop. A low refrigerant charge can be a sign of more serious AC issues to come.
A low Freon charge can cause compressor failure and general air conditioner inefficiency. This issue arises when the evaporator coils freeze due to low refrigerant levels. The insulation of the coils caused by the ice buildup eventually inhibits the cooling process. The compressor must work harder to compress the air as a result, which harms its motor.
The compressor is regarded as the most important part of the AC system, so damage to it will affect air conditioning. This does not, however, imply that you must completely replace your air conditioner. We will examine the sources of Freon leaks before learning how to avoid compressor damage.
