Attach The Refrigerant Can
With the AC still running, thread the refrigerant can to the port on the service hose. Let the engine run and the compressor turn.;
- Press the trigger on the refrigerant can for 10 to 20 seconds and let the gas go into the system.;
- Keep monitoring the pressure to make sure you do not overcharge the system.
- Do not charge the pressure to more than 45psi.
How To Keep Your Cars Ac Working
Modern life has spoiled most of us. Were used to traveling around with adjustable seats, auto-everything, and GPS so we never get lost. We also expect a cooling system we can set to the precise temperature for maximum comfort.
Your car AC is one of those things you take for granted. That is until it dies during the heat of the North Carolina summer. Then you realize how much you appreciate it.
You can ignore your cars AC system until it stops working. Hopefully, this doesnt occur on a road trip far from your trusted local repair shop.
Or you can schedule regular AC recharge services. Once every year or two is probably sufficient. Spring is a good time to do this.
We advise you to schedule an AC recharge before your unit stops blowing cold air entirely. If you notice that the air coming out of your vents is not quite as brisk, give us a call.
How The Car’s Ac Works
The cars air conditioning doesnt produce cold air as like as your home AC. It basically takes the moisture and heat from the air, which leaves the cool air in your car. Your car includes a refrigerant inside the AC which keeps fluid and gas at under pressure inside it. It keeps the gas under low pressure at 70psi when the system is not running. The amount of gas depends on the type of vehicle. The compressor compresses the gas into fluid when you turn on the system.
Then the fluid flow throws the condenser and removes the heat from the air and then come back to its previous gas state. Then it enters in the receiver drier to remove all the moisture. After that, it moves to the passenger compartment and removes the heat. That is how the ac of your car works.

How Do You Know When Your Cars A/c System Needs A Recharge
- The A/C is blowing warm air: The first, and easiest, way to tell if your cars A/C system needs a recharge is if its blowing warm air out of the in-cabin vents. Since the system operates by circulating the pressurized refrigerant, a lower amount of refrigerant will affect its performance.
- The A/C clutch is not engaging: When your cars A/C system is in full working order, youll occasionally hear a slight click when the A/C clutch turns on. However, if you dont hear the click , then its probably because the system isnt working properly and the refrigerant levels are low.
- Visible leaks: Another easy way to tell if your car needs its A/C system recharged or repaired is if you notice thin, greasy puddles on the ground underneath your cars engine bay. If the refrigerant is leaking that much, then youll definitely need to get it serviced.
Before You Get Started
First, you’ll need to find out what kind of refrigerant your car uses. The best way to determine this is to check your car’s owner’s or;repair manual.
If your car was manufactured after 1994, it uses R134 refrigerant. Older cars use R12 refrigerant, which is no longer manufactured. To get the AC working on a pre-1994 vehicle, you’ll first have to take it to a repair shop and have it converted to use R134.
You should also check your AC system;for leaks;before getting started. A leaky air conditioning system can’t cool as efficiently; running it without sufficient coolant could cause permanent damage.

Where Do I Find Ac Charging Where Dc Charging
Most charging stations that you’ll find today use AC charging. The usual charging speed is 22 kW, depending on the car that you own, as well as the power available to the charging infrastructure. It’s ideal for charging your car at home or work because you’ll need more time to load. DC charging, on the other hand, is more common near highways or at public charging stations, where you don’t have much time to recharge. But DC charging is making its way into home charging, offering new possibilities for customers since it allows not only fast charging but also bidirectional charging.;
Attach Can Of Refrigerant
Screw the dispenser hose and gauge onto the can of refrigerant. Attach to the low side port by pulling back the outer slip ring, pushing it on and releasing the ring. Next, start the engine, turn the A/C system on max and check the gauge reading. The compressor clutch should be engaged and the front of the compressor spinning. If the pressure is lower than 20 psi and the compressor is not engaged, then dispense refrigerant until the clutch engages. Be sure to shake the can first and every 3-4 seconds later.

A/c Recharge Services At Firestone Complete Auto Care
If you’re in need of a car A/C recharge service, look no further than Firestone Complete Auto Care. We offer an A/C Evacuate and Recharge, where we void the air conditioning system of old refrigerant and then recharge the system with new refrigerant. We then inspect the car A/C system’s pressure and temperature control to make sure everything is working correctly for a car air conditioner recharge service.
Preparing The Recharge Kit
As you unpack your kit, you’ll find a can of refrigerant, a flexible rubber hose, and a pressure gauge. Follow the instructions in the package to assemble the pressure gauge part of the kit. Usually, the hose is already attached to the gauge. Before you screw the gauge into the can of refrigerant, be sure to turn the gauge counterclockwise until it stops. There is a pin inside the assembly that pierces the can of refrigerant once everything is together tightly. This pin is controlled by turning the gauge clockwise until it pierces the can. But you don’t want to do this until you’re ready, so be sure to back it all the way out before you assemble everything.

How Do I Know If My Air Conditioner Needs Recharging
Unless you have at least a little bit of experience in engineering or as a mechanic, you wont always be able to tell the difference between low AC refrigerant and other problems. Dont worry about that for now. All you need to recognize is that if you have a malfunctioning car air conditioners in the Arizona heat. When you cant get cool in your car, its time to bring it into a Gilbert repair shop that understands your pain.
When you bring your car in, well investigate an AC leak in addition to other problems. An excellent first step is to examine your AC compressor. By watching how the clutch and pulleys engage, we can usually tell quickly if the problem is low refrigerant, electrical malfunction, or something mechanical.
In the case of an AC leak, bad electrical signals, or mechanical failure, the system may call for other small repairs. In many cases, though, there is a good chance that you need more of a refrigerant like R134a in your vehicle. Well get you back to an appropriate level of air conditioning refrigerant and send you on your way. Since we have all the required equipment on-site, its as easy as that!
Why Am I Limited In How Quickly I Can Charge My Ev At Home
The electricity in a car battery is DC. When you use a home EV charger, AC electricity is sent to the car from your home mains supply, and the cars OBC converts the AC to DC, which charges the electric vehicle battery.
This limits the speed at which the car battery charges because different electric vehicles have OBCs with different capabilities. For example, a Jaguar I-PACE has an OBC rated 7.4kW. This means the maximum you can charge in AC is 7.4kW. Even if your home charge point is capable of charging at 22kW, the I-PACE can only charge at 7.4kW. A Renault Zoe can charge at 22kW.
On a DC charger , the charge point converts the AC into DC before it reaches the car battery. This means the car doesnt need the OBC to convert the electricity from AC to DC, so it can charge a lot faster than on a home charge point. A Jaguar I-PACE on DC charge can charge up to 100kW. A Tesla Model X can charge up to 145kW. This type of charging is called;rapid charging.

How To Tell When Your Cars Ac Needs A Recharge
If you live in Gilbert, AZ, its nice to have functional air conditioning in your car for all the obvious reasons. Were not in the business of telling you things you already know, though, were in the business of car repairs and keeping your vehicle in the best possible condition. With that said, lets get straight into what an AC recharge is and how you know when you need one.
Why Are Ac Recharges Important
The time-honored practice of simply topping off your A/C with a can or two of refrigerant every spring is no longer acceptable. Your technician is obligated by Federal law to find and repair any leaks instead of simply adding more refrigerant as needed. Coupled with that is the fact that the new systems are quite intolerant of excess amounts of refrigerant onboard. Adding an entire 8-ounce can when the system is only an ounce or two low can actually damage the system.

Understanding Where The Power Comes From In A Car
The available plugs in your car can easily charge up a phone. The only question is, where does the power come from? The cars battery.
As long as your battery is alive and healthy, the charging ports in your car will charge your phone. Theres a part called an alternator that makes it work even better.
The alternators main job is to keep recharging your cars battery so theres enough juice. Without it, your cars battery will deplete whenever its used and eventually die. Think of it like the charger thats plugged into your phone.
The battery is plugged into all the electrical components in your car. As long as the battery is charged, it will provide the power that your car needs. As long as the cars moving, the alternator is spinning and regenerating your battery.
Its worth mentioning that an idling cars battery doesnt charge that fast. Without a load on the engine, the alternator doesnt create a ton of reserve power.
Reasons Not To Use Diy Ac Recharge Kits
Over time, your car’s A/C system will slowly but surely leak out the refrigerant gasses that allow it to blow cool, refreshing air into the cabin. When the system starts underperforming, and the air isn’t getting as cold as you like, it’s time for a refill on A/C refrigerant. But putting refrigerant in your car isn’t like filling the gas tank! While there are DIY A/C recharge kits on the market, here are three reasons why we think it’s best to avoid them. Instead, get professional A/C service for your car from the trained experts at Hanson Kia. We have the know-how to take care of your A/C system properly.
Verify The System Is Empty
Gauges at 0 psi
Presumably, youve discharged the AC system to make some repair and so you already know that it has no refrigerant. Its still worth verifying that before proceeding. At this point, both gauges should read 0psi. Note that you do not need to and should not open the valves. Do not open the valves.
The gauges will show pressure if there is any by virtue of being connected. If the pressure is higher than 0 on either side, you have refrigerant in the system and need to get it extracted by a professional. A mechanic should be able to recover the r134a for you fairly inexpensively, since he gets to keep the refrigerant to reuse for another customer.
Diy A/c Charging Does Not Evacuate Old Refrigerant
The reason your car’s A/C system needs to be recharged is that, over time, the refrigerant gas that makes the system work will leak out of the system. This process can take many years — but, eventually, every vehicle will need its A/C system recharged.
When you use a DIY canister to add more refrigerant, you can’t be sure how much is remaining in the system! This can lead to overcharging the system, which can cause significant damage. Instead, our professionals will begin by vacuuming out all the refrigerant from your car’s A/C system. This also removes any moisture that got into the system, which can also cause your A/C to run poorly. Then, once we know your car’s A/C system is totally free of stale refrigerant and moisture, we can fill it up with fresh refrigerant the correct way.

Signs And Symptoms Of An Overcharged Ac System
When your air conditioner is functioning properly it should come on almost immediately after you press the button in your car to get it going. If your car hasn’t been running in a while then you typically have a minute or two to wait before you start noticing any really cool air coming out, but there’s definitely a noticeable difference between a simple fan and the air conditioner when it’s working properly. That said, here are some symptoms you can be on the lookout for to let you know that you have an issue with your AC system.
Lack of Cooling:; As silly as it sounds, and as obvious as it sounds, this really is the number one sign that your AC system has been overcharged. If the liquid in the system doesn’t have the right amount of room to depressurize because it’s overcharged, then it will not be able to provide the cooling that it’s supposed to. You may experience a very slight amount of cool air coming through when you turn the AC on, but it may also just be the ambient temperature of the air around you, and in the worst circumstances it may actually start blowing out hot.
It should be noted that this may not happen in every system however because some air conditioner compressors have an emergency bypass that prevents pressure from destroying the pump.
Pro Tips To Recharge Car Ac
Over the years, The Drives editors have worked on dozens of vehicles and logged hundreds of hours wrenching under fluorescent garage lights. During our experiences, weve picked up a few tricks and noted the important things. Heres what we learned in our times recharging car AC.
- Do not overcharge the system with too much refrigerant. This could damage the systems internal components.
- If a system gets cold after recharging but reverts to pumping out warm air, there might be a leak in the system. An easy way to detect that is by using a refrigerant leak detector.

Evacuating And Charging Car Air
Now a days with strict EPA laws we really call this process recovery and charge, because we dont let any refrigerant escape into the atmosphere. Evacuating is a term used to describe the complete removal of all Freon.
This is done by creating a vacuum in the system by connecting a vacuum pump. This process gives you a fresh start and it also pulls all air and moisture out before recharging.
This is a very important factor in the overall performance of any car air conditioner. Air or moisture that is left inside the system reduces the efficiency and can eventually lead to major problems such as compressor failure.
Air causes excessive pressure and can restrict the refrigerants ability to change its state from a gas to liquid. Moisture on the other hand can freeze up and restrict the refrigerants flow. Moisture also forms an acid when mixed with refrigerant which can intern cause corrosion inside your car AC system.
A vacuum pump removes this air and moisture from all internal components. It also provides a clean slate for charging car AC. Refilling the system known as charging is when Refrigerant is added through the systems service ports.
Charging through the low side service port is the recommended procedure on most vehicles unless an electronic charging station is used.
