- Set the Hyundai down. Put the gear selector in Park, engage the parking brakes, and let the vehicle idle.
- Activate the air conditioner. Set the blower to maximum and the temperature control to the lowest level.
- the Hyundai’s hood should be opened. Find the service port for the low-pressure air conditioner, then take the top off.
- Find the service or charging port for the air conditioner. The Elantra’s A/C port is situated close to the firewall, behind the engine.
- You might be attempting to connect to the high-pressure port, which is a different size than the low-pressure port, if the connection from the A/C recharge kit does not fit on the port. This video demonstrates how to find the Hyundai’s A/C charging port if you’re still having problems.
- Connect the AC charging kit following that.
To your air conditioning system, add refrigerant. Once the gauge is connected, check the gauge to determine the pressure in your air conditioning system. The gauge reading will be in the white zone if the pressure is low. Depending on the A/C kit you are using, the gauge should be in the green or blue area if the pressure is normal. Except when the automobile is off, you shouldn’t read in the HIGH/RED zone.
- Don’t tip the can over. Shake the can every two or three seconds while the system is charging. Release the trigger to stop charging every few seconds. Examine the pressure gauge. (With the engine off, it is typical for the gauge to read overcharged.) The A/C system shouldn’t be overcharged. Once the pressure is within the permitted range, stop recharging the A/C system. Only take measurements when the engine is operating.
Cut the power to the A/C recharge kit. From the A/C port, remove the quick connect. Replacing the cap Don’t tighten the cap too much. Shut the hood, and enjoy your air conditioning.
Remember that a system with a significant leak may lose the refrigerant quickly and need repair work before being refilled with the substance.
A/C systems that are not in use are not advised to use this approach. A vacuum pump must be used to remove the air from an empty A/C system. Depending on the capacity of the system, topping off the Hyundai A/C system is relatively simple and can take up to twenty minutes.

Undoubtedly a leak. The most typical one is located just outside the low and high ports. Spray some soapy water inside after opening the cover; if it bubbles, you’ve located the leak. That can be fixed without draining the system. All you require is a tool for it. Get yourself a set of ac air gauges if you really want to handle your own recharging and repairs. HF is effective and reasonably priced. Use only pure R134-a refrigerants. YouTube has a ton of how-to videos on the subject. However, bet on the gauges. Stay away from cans of fast recharge kits. Good fortune.
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.
How much does repairing the AC on a Hyundai Sonata cost?
Hyundai Sonata Car AC Repair typically costs $249, which includes $116 for parts and $133 for labor. Prices may change based on where you are.
Should I refuel my own car’s AC?
Nothing is more annoying than navigating a car with a broken air conditioner. But I needed to know “should I recharge the AC myself?” before purchasing a can of Freon and doing it myself.
The air conditioning system in a car is closed, which implies it is airtight. If there isn’t an underlying issue, the refrigerant shouldn’t leak. You shouldn’t need to recharge the AC unit unless it requires repair.
By overcharging or delaying a trip to a professional while the issue gets worse, using a DIY AC recharge kit could make matters worse. Let’s examine how AC is recharged and why AC recharge kits fall short.
Is it difficult to recharge the car’s air conditioning?
Has the A/C in your automobile stopped working properly? Over time, refrigerant can slowly leak from your car’s air conditioning system, but you can easily recharge it yourself and get it working again in only 15 minutes.
When should a car’s air conditioning be recharged?
Most of us are spoilt by modern life. We are accustomed to driving with adjustable seats, automatic transmission, and GPS to ensure we never get lost. For ultimate comfort, we also anticipate a cooling system that we can regulate to the ideal temperature.
You likely take the air conditioning on your automobile for granted. That is, until it perishes in the sweltering summer heat of North Carolina. Then you understand how much you value it.
The air conditioning in your car might be disregarded until it breaks down. I hope this doesn’t happen on a long drive away from your go-to neighborhood mechanic.
Alternately, you might plan routine AC recharge services. Most likely once every year or two will be plenty. The time to accomplish this is in the spring.
Why isn’t the air blowing chilly in my Hyundai Sonata?
A refrigerant leak, an electrical climate control issue, or an issue with the air conditioning compressor are the three most frequent causes of air conditioning problems in Hyundai Sonatas. A refrigerant leak might not be detected until the air conditioner stops blowing cold, though.
How can I tell whether the AC in my car lacks freon?
- Warm Air is Blowing from Your AC. 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.
- When the A/C clutch engages, pay attention.
- Leaks of Visible Refrigerant
- Warm Air is Blowing from Your AC.
- Leaks of Visible Refrigerant
Why isn’t my car’s air conditioning blowing chilly air?
The requirement for a recharge is the most frequent reason why a car’s air conditioner doesn’t get chilly enough. You can replenish your refrigerant on your own, but scheduling an appointment with a neighborhood reputable auto shop will save you time and ensure the service is done correctly.
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.
Why does my automobile blast hot air even while the AC is on?
One of the most frequent causes of hot air flowing from your car’s air conditioner is a refrigerant problem, more specifically, a refrigerant leak. Your car’s refrigerant levels may be too low or there may be a leak causing this refrigerant loss.
Can I fill my own car with Freon?
The air conditioning in your automobile should be really frigid if everything goes according to plan! Enjoy.
If not, let’s attempt to determine what went wrong:
Be tolerant. To increase the pressure, a significant volume of refrigerant is required. Make sure the dispenser is correctly attached to the fill port if you are still experiencing problems.
Make that the condenser is still engaged. When the condenser disengages, the pressure may increase significantly. I am unable to advise you to attach the dispenser to the fill port without a can and squeeze the trigger to let the extra refrigerant out if the pressure is still too high because it is against the law to do so. You must have a mechanic work on your car.
Add half a can of freon if your compressor won’t turn on. It is probably broken if it still won’t turn. No more refrigerant should be added! To fix this issue, a mechanic is required.
How can I check the amount of refrigerant in my car?
How can the refrigerant level in a car be checked? Recently, the weather has been unusually warm, so I’ve been using my car’s air conditioner more frequently, but the air doesn’t feel as chilly as it used to. Before I go to a repair, I want to check to see if my refrigerant is low because it might just be the heat making me sick.
In less than two minutes, find out if your auto insurance is being overcharged.
It might be upsetting to discover that your air conditioning 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:
- security glasses
- AC meter
- Thermometer
When you have your materials:
- Examine the air conditioner. Visit the mechanic as soon as you notice any worn-out parts or loose clamps.
- 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. If you’re having trouble locating the ports, check your owner’s manual.
- 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.
- Put the thermometer in the vehicle’s center vent, and then let it run for a while.
- 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.
- If the temperature on the thermometer is 40 degrees Fahrenheit or less than the outside temperature, your air conditioning is operating as it should.
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. The Jerry app, a certified broker that provides end-to-end support, compiles inexpensive estimates from up to 50 top firms, assists you in switching plans, and even assists you in terminating your old policy.
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.
