- 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.

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 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.
How can I tell whether the AC in my car needs to be recharged?
If the air blowing out of your car is warm or hot, that may be the simplest sign that something is wrong with your air conditioner. The evaporator core won’t achieve the ideal cooling temperature if your car has too little refrigerant. The air may blow warmly after beginning cold. It might also never get cold at all. It’s time to set up an A/C Performance Check in any case.
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.
Can I refuel my AC on my own?
When someone talks about charging an air conditioner, they mean adding extra refrigerant and making sure the system is appropriately pressured with the added refrigerant.
A qualified heating and cooling expert must be contacted if you require refrigerant for your air conditioner. Only a qualified professional is allowed to recharge your home’s HVAC system in accordance with EPA standards. Even if you have a kit for home air conditioner recharging, you should never attempt to recharge the air conditioner yourself. If the refrigerant is not handled properly, it could be dangerous for both you and the environment.
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.
Is recharging the AC in a car worth it?
In a car’s air conditioning system, the refrigerant practically never runs out. As a result, it is not required to recharge the air conditioner with freon when there are obvious leaks. Recharging your air conditioner annually or even every two years is not required. The air conditioning system in your car should start cooling at a slower rate and start to work much worse. This is the best indication that it needs to be recharged.
You should seek assistance and have your air conditioner checked out as soon as possible if it is not blowing as much chilly air as it once did. A technician will perform an evac and recharge service after checking for refrigerant leaks in the system. However, it will be necessary to repair the damaged parts if the technician finds even a small leakage.
What location does the AC recharge port have?
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 long does it take the car’s air conditioning to cool down after a recharge?
Soon after the recharge is complete, your air conditioner should begin to blast cold air. Even though certain systems might take longer, the time after the recharging process shouldn’t exceed two hours. Any of the following causes could be the issue if the air conditioner doesn’t get cold after being recharged.
1. The AC and the automobile compressor are not connected.
Refrigerant troubles in a car air conditioner are frequently caused by compressor problems. This could be the cause if you discover that the AC is still blowing frigid air after being recharged. That will require you to visit a mechanic so the AC may be checked out.
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
Which side do you use to charge the AC in your car?
Find the low side service port as the initial step in charging your device (or low-pressure port). There are two service ports on each auto air conditioning unit: one on the side with high pressure and one on the side with low pressure. For safety reasons, you should recharge with AC Avalanche refrigerant using the low side service connection. Never use the high side port to charge.
What type of refrigerant can I use in a 2014 Hyundai Elantra?
Essential Cooling & Heating Products for the 2014 Hyundai Elantra Coupe. Certified A/C Pro R-134a PAG 46 Refrigerant Oil With ICE 32 from Interdynamics (8 fl. oz.)
Why isn’t the AC blowing chilly air in my car?
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.
Why does my car’s AC run but not blast cold air?
Leaks or compressor problems are the two most frequent reasons for faulty air conditioning. If your air conditioner is blowing chilly air but not frigid air, the issue may be a clogged filter, a cooling fan or radiator issue, or it may just be that your AC needs to be recharged.
Why does my air conditioner keep blowing hot air?
- Examine the thermostat. Make sure your thermostat is set to “cool” and that the temperature is low enough. It might seem too simple to overlook.
- Examine the breakers.
- Examine the filter.
- Check for ice in the outdoor unit.
- Check for debris on the outdoor unit.
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.
How can a malfunctioning car AC compressor be detected?
When you turn on the air conditioning in your car, you might hear some odd noises; if so, the compressor is most likely the source. When triggered, this component may grind or whine once it starts to malfunction. These noises are the result of internal parts malfunctioning, such as the bearings. Check to see if the noise ceases by turning off and back on your air conditioning. If so, you have an AC issue.
