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 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.
What does it cost to recharge the AC in a car?
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.
How often should your car’s AC be recharged?
The majority of automakers advise servicing or regasing your car’s air conditioning system every two to three years. An air conditioning service every two years will keep the gas topped up and the system oiled so you always have a cold blast ready when you need it most. Whether you use your car’s air conditioning frequently or scarcely at all, air-con gas will continue to penetrate through the system over time.
Even the most expensive cars will lose roughly 10% of their air conditioning system’s gas per year, which results in less cool air. Also bear in mind that a malfunctioning component will make your engine work harder, increasing fuel consumption.
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.
What does it cost to recharge an AC unit?
One of the most frequent AC services is the recharge of the refrigerant. You will spend far less if the problem is as simple as adding refrigerant and doesn’t call for a significant repair. However, the price of a house air conditioner recharge depends on your cooling needs and whether your system still uses Freon or R-22 refrigerant.
According to Home Advisor, a Freon refill will typically cost between $100 and $350 in 2021. However, prices are still rising. The expense of refilling an earlier, larger R-22 system can reach $600 or higher. R-410A costs between $3 and $8 per pound, while R-22 costs between $20 and $50 per pound (most systems require 6 to 15 pounds).
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.

How many AC recharge cans do I require?
The average car can contain between 28 and 32 ounces of refrigerant, or roughly two to three 12 ounce cans, although larger cars and those with rear air conditioning can probably hold more. The system capacity for your particular car can be found in your vehicle’s manual.
How can I tell if the freon in my air conditioner is running low?
- 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 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.
How can I fill my car up with refrigerant?

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.
How can I tell if my air conditioner needs more refrigerant?
You will be charged if your air conditioner’s refrigerant, or Freon as it is also known, is low. You’ll probably pay a higher electric bill than usual, and you run the chance of an expensive air conditioner malfunction.
Be mindful of these 7 indicators of low refrigerant to ensure cost and energy savings this year.
- Your house takes a while to chill down. Your air conditioner is working overtime to cool your house when the weather is high. With high indoor temperatures and hefty costs, low refrigerant makes this situation worse.
- The air vents don’t blow cool air. Low refrigerant could be one of the causes of warm or lukewarm air blowing through the vents, which could be an indication of many various problems.
- Your set temperature is never attained. You need to have your air conditioner checked if you set the thermostat to 75 but the thermometer never reaches that level.
- The cost of your electricity is more than usual. You can find problems with your HVAC system by comparing your utility bills from month to month and from year to year. Have your air conditioner serviced if your electricity bills are higher than usual.
- refrigerant lines with ice. Check the unit for ice buildup if you think your air conditioner’s refrigerant levels are low. When an air conditioner lacks refrigerant, ice can build up on copper tubing or the evaporator coil.
- The area around the heater is wet. Water may accumulate close to the furnace when the ice that builds up on the refrigerant lines melts. After that, the water may drip to the ground or into the furnace. Never allow water to accumulate on the ground close to your furnace.
- noise that bubbles or hisses. If you have a leak, it is why your refrigerant level is low. An AC service specialist will need to fix the leak if there is a hissing or bubbling sound coming from the system.
Don’t let hot temperatures and high energy expenses brought on by low refrigerant mar your summer. Service your air conditioner right away to restore both your home’s temperature and your electric bill to normal.
