If you wanted to recharge the system, you would first need to discharge or evacuate the system because newer cars (those built in 1996 and later) use r-134a freon. I would suggest taking it to a repair because moisture is really harmful for an air conditioner unless you have the tools to charge and expel it. You can simply be low or have a leak. With high pressure and moving elements with seals (such as compressors), automotive air conditioning systems have what are known as calibrated leaks. Most car manufacturers advise servicing every four years. Hoses attached to service ports on the high and low sides of machines and gauges allow for both recharging and exhaustion. I can assure you that the a/c performance will be terrible if you simply release the freon and then add.
Therefore, adding freon alone is not advised. Where are the finest shops to get this done?
Before working for two dealers, I believed independent businesses charged less, but I was mistaken. Most vehicles have the dye from the factory if the shop has good instruments (most evacuation machines will display how much freon came out) and they will leak check for you (using a black light to search for leaking dye). Inquire about costs up front. I am aware that it can be challenging to identify trustworthy stores.

How to easily recharge AC refrigerant
The Sonata’s air conditioning system has two ports. One has the designation H for high pressure, and the other has L for low pressure. With a DIY AC recharge kit, you can recharge your AC through the low-pressure port.
- Your Sonata’s hood should be opened.
- Verify the type of refrigerant that your car utilizes. Usually, the owners manual or beneath the hood are where you can find this information.
- Start the car.
- Set the fan speed to its highest level and turn on the air conditioning.
- Connect the AC recharge kit after removing the cap from the low pressure service port with the letter L. Note: If the ports on the AC hoses are not labeled, try attaching the recharge kit to both of the unlabeled ports. Only the low pressure port will allow the recharge kit to fit securely; the high pressure port will not.
- Release the refrigerant into the system while giving the canister a slight shake, continuing until the recommended pressure is reached. Note: For suggested pressure values, refer to the next section.

Yes, consult a professional who has the necessary tools and training. Contrary to what you may have seen on videos and TV advertising, the average individual cannot perform AC service himself.
Releasing refrigerant into the air is harmful and technically against the law (you’re required to have a system to recover and recycle it). Direct contact with leaking refrigerant might result in significant harm to the skin or eyes (frostbite or blindness). Not worth trying to save costs by a little.
How can you tell whether your automobile needs freon?
If you pay close attention, you can hear a “click” when you turn on the air conditioning in your car. This is the clutch engaging. The clutch won’t engage if the Freon levels are too low, which means there isn’t enough refrigerant for the compressor to pressurize.
What happens if you fill your automobile with the wrong type of freon?
Refrigerant types cannot be mixed, and using the incorrect one in your automobile will harm the air conditioning system! DIY air conditioning charging might not be for you if you are unsure of the type of refrigerant your car uses.
How can I check the level of freon in my air conditioner?
The nearest vent should be the first item you examine. The air conditioner will start to blow warm air instead of chilly air if the refrigerant level is low.
Put your palm up against the nearest vent and feel the temperature of the air to test this. The likelihood is that the coolant level is adequate if the air is still cold. However, if it’s lukewarm, you might want to move on to the other inspections because the refrigerant level might be low.
What does it cost to fill a car with freon?
How much does it cost to refuel your car’s air conditioning? If you get it changed properly, you may pay anything from $150 to $300 on average. However, the cost of the car AC recharge kit if you go the DIY method would range from $40 to $50.
To which side of the system do you add the freon?
Check what type of freon your car utilizes first. A tag indicating this should be located under the hood or on the radiator cover cowl. Search for 134A. This Instructable does not apply to you if it says 12. Although conversion kits exist, they are outside the purview of this demonstration. Now look at the illustrations to see what an AC system’s fundamental components are. We won’t talk about the pieces you can’t see because they are not important to understand in order to charge the system.
A pump or compressor in the most basic AC system transfers low pressure gas to high pressure. It is termed a compressor because of this. The high pressure gas then travels to a condenser in front of your radiator. You may have observed that while the air conditioner is on, your fan runs frequently. To cool the hot compressed freon, that chilly air is forced into the condenser. Then something fantastic happens. After cooling, the heated freon transforms from a hot gas to a semi-hot liquid. Count on me for this. The liquid continues to be under high pressure and at a high temperature until it is utilized to cool the evaporator.
It is no longer a liquid as it enters the evaporator; instead, it is a low pressure, cold gas. As soon as it exits the evaporator, it travels via hoses to the accumulator/drier, which is just a sizable tank for collecting any liquid that could have leaked out with the gas. After that, the cold, low-pressure gas returns to the compressor to restart the cycle. You may have noted that the system has two sides with different pressures—this is VERY IMPORTANT. You’ll just be working on the side with little pressure. Only the LOW PRESSURE SIDE receives the freon addition. Since the fittings on the high side and low side are different in size and shape for safety’s sake, the hose tool you purchased is only designed to hook to the low side.
How can you tell if your air conditioner needs more Freon?
- The time it takes to cool your house is far longer than it should be.
- The cost of your utility bills has increased.
- Your air vents are not blowing chilly air.
- The refrigerant line has begun to accumulate ice.
- You notice that your device is making loud or strange noises.
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 happens if the Freon in your air conditioner runs out?
You may be low on freon if you check your air conditioner or outdoor central air unit with the fan and notice frost forming on the refrigerant line.
The evaporator coil gets too cold when your air conditioner runs out of freon, which causes the cold liquid refrigerant to flow back into the refrigerant line. As a result, the nearby moisture on the refrigerant line will begin to freeze. You need freon if this is the case.
If you do not have this problem fixed, freon could leak into the compressor unit. If this occurs, your compressor could be damaged or destroyed, resulting in an even more costly issue. You could even have to replace the AC system as a whole.
Without Freon, will the AC compressor start?
Without Freon or another refrigerant, the HVAC compressor cannot operate. The compressor has some cooling power and can function with little refrigerant. It is not advised to operate the air conditioner with insufficient refrigerant, though.
When installing air conditioners, HVAC workers utilize gauges to check the correct refrigerant level. The unit’s “charge” is the name given to this measurement. This level of refrigerant is maintained by the air conditioner. Only if a refrigerant leak occurs or if the person who installed or repaired the unit did not add the right amount of refrigerant would the device be undercharged.
For proper operation, air conditioners need to have the right amount of refrigerant. An undercharged system can still function, but cooling power is decreased, the system has to work harder, and eventually the air conditioner will stop working. The compressor may overheat if there is less refrigerant than what it is designed to handle. If the compressor overheats, it can be necessary to replace the compressor or the complete air conditioner. The amount of heat that the evaporator coil can absorb is further constrained by low refrigerant levels. Possible freezing and eventual failure of the coil. Additionally, when the refrigerant level is low, the system uses more energy, which raises utility costs.
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.
How frequently is freon recharged?
Here at Needham, we frequently receive the inquiry “How frequently should I be adding refrigerant to my A/C.” The solution is straightforward:
A central air conditioner shouldn’t require additional refrigerant because it doesn’t “consume up” any. Only if you have a leak will you ever need to recharge (add refrigerant to) your air conditioner; after the leak is addressed, the issue should be resolved.
However, each summer as they recharge the air conditioner, we hear from consumers whose former HVAC technicians advised them that “these things happen to elderly equipment.” You require better technicians if that is what is happening to you.
