The RAV4’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.
- the RAV4’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.

Warning: To prevent unintentional exposure to dangerous chemicals in the refrigerant, put on gloves and safety glasses before charging the AC. Additionally cryogenic, it has the potential to severely frostbite skin upon touch.
Quick disconnect fitting for AC recharge charging port
Some recharge kits have this fitting that quickly and securely connects to the AC recharge charging connector.
Your air conditioner probably lost some refrigerant during the winter if it was blowing ice-cold air last year but is now hardly cooling. When aging seals shrink and some refrigerant leaks out, that occurs in older automobiles.
Typically, turning on the automobile air conditioning will send you back to the freezing cold. If your car was built after 1993 and is filled with R-134a refrigerant, you can complete that task by yourself (to make sure, check the label under the hood or the specifications section of your owner’s manual).
Restrictions may apply to the sale of R-134a refrigerant to consumers in several states. The cans may occasionally be designed differently, necessitating various charging techniques. All AC issues won’t be resolved by charging the AC. However, if you’re willing to risk $50 on a rechargeable ac kit, you could become a cool dude in less than an hour. By performing the auto ac recharge yourself, you can save roughly $100 on labor.
Pick up an R-134a A/C recharging kit at any auto parts store. Because it included a quick-connect fitting and reusable gauge, as well as a seal conditioner ingredient in the refrigerant, I used the A/C Pro product you see here. For an AC recharge for a car, however, any brand will work. A word of caution: Many commercial recharging kits utilize oils and seal conditioners that are incompatible with the electric AC recharge compressors in hybrid vehicles. A fatal electrical shock might be caused by using the incorrect auto ac recharge kit. Before making a purchase, verify that your hybrid vehicle is compatible with the car ac recharge product on the label. Consult a professional if you’re unsure.
Caution
If used incorrectly, refrigerant can result in frostbite and severe eye damage. Wear gloves and goggles when doing the process, and pay close attention to all the warnings in the package instructions.

Do AutoZone air conditioners require recharging?
Most of the time, this may be resolved by using a trusted stop leak additive to halt any leaks. Visit AutoZone for an AC recharge when the time comes. Along with other things, we sell R134a refrigerant, PAG46 oil, AC stop leak, and AC system cleanser.
Will AutoZone re-charge your automobile using Freon?
If the system has been overcharged, it is best to have the car serviced so that the system may be properly evacuated by an AC machine and then serviced to the proper level. 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.
Am I able to add my own refrigerant?
You shouldn’t ever have to add refrigerant to your air conditioner yourself, as you are unable to do so. Before being dispatched to retailers, air conditioners are either factory-charged with the appropriate amount of refrigerant, or they are dry-charged during installation. A low refrigerant charge indicates that it was either charged insufficiently at the manufacturer (very improbable) or by your installation professional (not if you worked with us), as refrigerant is not consumed by your air conditioner at any stage in the system’s operation. maybe there is a leak.
Unfortunately, the majority of homeowners encounter that last issue. One of the most serious issues with your air conditioning system that you might experience is a refrigerant leak. Low refrigerant charges put your comfort and your finances in danger, and using an air conditioner with little refrigerant can seriously harm your system. If given the chance, it might potentially damage your compressor. In these situations, a complete AC replacement is frequently the outcome.
What Function Does the Refrigerant in My Air Conditioner Serve?
A very significant one. Your central air conditioning system would be completely worthless without refrigerant. A fluid used to transport heat called refrigerant. It can easily transition between being a gas and a liquid, and back again. Heat is removed from the air passing over the evaporator coil as refrigerant evaporates there. The refrigerant is then squeezed outside and heat is released there. The cycle keeps going until your home reaches the desired temperature.
How Do I Know if I Have a Leak?
If you believe you may have a refrigerant leak, you should arrange for urgent HVAC services with trained experts. Of course, you must first realize that you have a refrigerant leak before you can take that action. The “good news comes in at this point. Although a refrigerant leak is a major issue, there are a number of indicators that can let you know whether one is present in your system.
- Simply put, your house isn’t cooling off like it used to. It stands to reason that a low refrigerant charge will make your home feel less pleasant than it did because the entire cooling process depends on refrigerant’s capacity to remove heat from the air in your home.
- Your system only operates briefly. Your air conditioner may overheat if it is having trouble keeping up with your cooling needs because of a low refrigerant charge. As a result, the system can end up short cycling in an effort to protect itself by granting itself a cooldown interval.
Is refrigerant liquid or gas?
The mechanical components just serve to induce the exchange of hot and cold air; the refrigerant itself really cools the house. Refrigerant is a chemical that, when changed from a gas to a liquid state, has a remarkable capacity to absorb heat.
The refrigerant can absorb heat from within your house and release it outside when it undergoes a state change as a result of compression and pressurization. While the air conditioning system is functioning, the refrigerant circulates continuously in a loop to convert hot air to cool air.
What does it cost to recharge the AC in a car?
Taxes, fees, and your specific make and model are not taken into account in this price range, which is based on national averages for all automobiles. It may also be necessary to do related maintenance or repairs including replacing the fuel filter, the O2 sensor, and the spark plug wires. Use the RepairPal Fair Price Estimator to get a more exact quote depending on your make, model, and location.
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.
Where does the refrigerant in the air conditioner go?
As you might have imagined, an AC refrigerant aids in the cooling process of any appliance that needs cooling, including your air conditioner as well as a refrigerator, freezer, or other similar devices.
Understanding how an air conditioner operates will help you better understand how an AC refrigerant works. In order to remove heat from a room and transfer it to the outside, an air conditioner uses refrigerant, which is housed in copper coils in the evaporator and condenser. The refrigerant undergoes this transformation, going from a low-pressure gas to a high-pressure liquid.
This is the simplest way to explain how refrigeration works. The heat is subsequently released into the environment by blowing over the high-pressure liquid using a fan. This liquid undergoes additional compression before ejecting quickly via a specialized nozzle to change back into a gas and start the next cycle. Another fan then blows over this cold gas to blast cold air into the room, and the cycle repeats.
How does an AC flow sensor function?
Late model A/C systems with an electronic control valve depend on a series of signals between the compressor, thermistor, pressure transducer, ECU, and related sensors, as stated in gpd Tech Tip #9, “Electronically Controlled Clutchless/Variable Drive Compressors. Before turning on the compressor, modern systems can rely on confirmation indications from over 20 different sensors.
A refrigerant flow sensor is now present in some modern compressors; it is often placed on the compressor’s discharge side. In order to confirm correct refrigerant flow, it communicates with the ECU. In order to verify the programmed flow rate based on the engine speed, angle of the compressor swash plate, and environmental conditions, the ECU uses the refrigerant flow sensor. Any system flaw that prevents refrigerant flow will cause the ECU to send a signal to the compressor to shut off. The ECU will stop the compressor from pumping if it does not receive the intended measurements, regardless of whether the compressor and/or sensor are broken or not.
- Try restarting the car if the A/C system starts up with the motor running but stops cooling after 15 minutes. If the problem recurs, the flow sensor can be to blame for the compressor cutting out.
- Despite not having the flow sensor, some aftermarket compressor choices may be described as being the best fit for a given application. Make that the replacement compressor has a flow sensor if the original compressor has one.
The fit, form, and function of gpd compressors are intended to match or exceed those of OE components. Refrigerant Flow Sensor Replacement Compressors at gpd (TSE and TSE17C Styles) *Not all compressors with a sensor for the flow of refrigerant are displayed.
