Please note that you may need to recharge your air conditioner from time to time to keep it at an optimal performance level. Other things you can do include selecting different kinds of replacement AC components and changing out the serviceable parts in your old unit.

However, it is best to check for leaks in your new AC unit if it suddenly stops working. Your local mechanic may be able to find a way to check for leaks if it seems elusive. Its always better to contact a nearby workshop specializing in repairs for vehicles and ask them about their methods for diagnosing problems.

Top Up The Refrigerant

If the gauge says, pressure is low, the refrigerant needs topping up.

Disconnect the gauge from the port. Take the A/C Pro R-134a Recharge Gas and give it a thorough shake before attaching it to the gauge by screwing it on.

With the engine still running, reattach the gauge to the port. You can then start recharging the refrigerant. Doing so is easy. Just squeeze the trigger on the cannister while shaking the can. Make sure you keep the can upright throughout the process.

Stop every so often to check the pressure level using the gauge. The gauge will indicate, Filling, release trigger in 15 sec. to read pressure. Keep filling and following this release instruction until the filled message appears. Its important to closely follow these messages so you dont overcharge it.

When the needle reaches the green zone and the car blows cold air, youre done. Its that simple!

Locate The Low Pressure Side Refrigerant Fill Port

1. Pop the hood.2. Locate the refrigerant fill port on the low pressure side of the system. This will have a small plastic lid with an L printed on the top. Unscrew this cap to reveal the port.Where is the fill port? For most vehicles, the low pressure side fill port is located on the left side of the engine bay. It will often be a small section of metal pipe that has two lengths of rubber hose coming off either end. Look to the back of the engine bay called the firewall. Protruding from the firewall should be two pipes or hoses next to one another, one larger than the other. Follow the larger hose to find the low pressure side fill port. The photos depict the location of the fill port on two different late model engines.DANGER! Do not touch anything you are unfamiliar with. Almost everything in the engine bay moves and/or gets hot. The high pressure side hoses get very hot, do not touch them. It is okay to touch the low pressure side hoses, they should be around ambient temperature.

How Do I Get My Cars A/c System Recharged Or Repaired

How to Recharge Your Car

While you can definitely buy a can of the refrigerant at your local auto parts store and look up a handy YouTube video on how to recharge your cars system, we recommend bringing it to an ASE certified mechanic instead.

Most auto repair shops will have the necessary tools and machines to properly and thoroughly check your cars A/C system and recharge it if necessary. And if it ends up that the system needs to be repaired, then they will be able to take care of that as well. Air conditioning refrigerant is harmful to the environment, so having the proper equipment to add more or evacuate your cars A/C system is necessary.

How To Charge An Air Conditioner

There are two ways you can charge the air conditioner system in your car. You can make use of the manifold gauges, or you do it directly using the refrigerants. The good side of using the manifold gauge is that it helps you keep a close tab on the process.

It helps you know the level of gas you are sending into the compressor, and with it, you get to know if you are short or full of gas. However, you have to trust your instinct with the refrigerant because most do not come with gauges.

However, you can have a successful recharge if you have a scale to measure your refrigerants.

Car Ac System Blowing Warm Air

If you wake up to an AC blowing warm air instead of cold air, it’s due to severe leakage. For this, you’ll need to have a professional find the leak and fix it before topping up the refrigerant. While some DIY recharge cans contain seal leak compounds to fix small leaks, larger leaks remain unattended.

At Hillmuth Auto Care, we have specialized repair equipment that helps our professionals locate leaks in the AC system to repair them and prevent the problems from reoccurring.

Are Air Conditioner Recharge Kits Bad?

Fundamentally, recharge kits are not bad. However, they often do more harm than good. They are designed with a stop leak which plugs small leaks as the refrigerant and compressor oil run through the system.

Unfortunately, this method can easily clog the air conditioner components like the pump, hose, and compressor. Recharge cans make it easy for you to overfill the air conditioning system and cause bigger problems.

Are Air Conditioning Recharge Kits Worth It?

No, they are not because they don’t fix broken AC systems. Instead, they simply recharge refrigerant and leave the cause of the problem unattended. So while a recharge may get cool air blowing again, it masks the real issue as it worsens. Eventually, you may end up fixing a leak, replacing damaged components, and recharging the AC system.

Recharge Your Ac System

Check your owners manual for tips or instructions during the recharging process. However, usually, you will have to start the car and let it run on idle. After that, use a can of refrigerant spray to fill the line with gas before closing all the valves. It is best to leave your car running for at least 10 minutes after installing everything back this will help you ensure that you have connected all parts correctly and nothing can become loose.

Does My Air Con Need Recharging


Manufacturers recommend that your air con is recharged every 2 years. As your car or van air conditioner is not checked as part of your MOT test and regassing is not typically included in your Service, it is important to make sure that you include recharging as part of your regular vehicle maintenance routine.

If your AC is blowing out warm air or only works intermittently, an AC recharge can bring back cold air when you need it most on hot days and can also improve your fuel efficiency as there is less strain on the system and engine. Unpleasant smells coming from the air vents also suggest that your air con needs some attention.

How Do I Know Which Air Con Gas I Require

R134A gas is common in vehicles manufactured before 2014. All vehicles with air conditioning manufactured since 1st January 2017 include the newR1234YF air con gas which is more environmentally friendly. Since this date, manufacturers are no longer allowed to use the older R134A air con gasin a bid to reduce global warming as the old gas is believed to be more damaging to the environment. R1234YF gas was phased in by vehiclemanufacturers over time so vehicles rolling off the production line between 2014 and 2016 could require either gas. To find out which type of air conditioning gas your car needs and to start a booking to have your air con gas recharged, enter your registration in the field above.

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 to Recharge Your Car

    Do you know how often to recharge the AC in a car? You are probably asking yourself how long does the car AC last? In general, technicians recommend having the air conditioner serviced once a year. It wont always need to be regassed, but it should be checked. During this service, the systems are also checked for leaks, ensuring everything runs efficiently.

    Your vehicle could go up to five years without having refrigerant added. However, even the most efficient vehicles will lose around 10% of the gas each year.

    How often should I get my car air conditioner serviced? Just like with your car engine, you dont want to wait until theres a problem to get help. Its best to have regular air conditioning checks and add Freon when needed to ensure the system continues running its best. Without regular maintenance, you allow the vital parts to experience more wear, leading to premature damage.

    Your Cars Air Conditioner Operates On A Closed System

    Considering your cars tires, brakes, and fluids need to be changed in regular intervals, for the most part, you would think that its air conditioning system follows the same type of schedule. However, that is not the case since it runs on a closed system.

    A closed system means that your cars A/C system recirculates the refrigerant which is the coolant that makes the air that comes out of the vents cold so if it needs to be recharged, then there could be a leak in the system. However, cars do tend to lose some refrigerant over time naturally, but its typically not enough to warrant a recharge every year.

    As noted, Unless your cars A/C is in need of repair, theres no need to top off the system.

    What Happens If You Overcharge Your Ac

    If you perform this service yourself, you will have the correct refill kit to guide you in adding the correct amount of refrigerant to your vehicles air conditioning system. However, it is possible for too much refrigerant to be pumped, causing the air conditioner to overcharge.

    The result is that your compressor is unable to provide the proper cooling capacity and warm air is instead delivered into your vehicle. So, it is best to be very cautious when assuming that a non-working air conditioner is low on refrigerant, as this is not always the case.

    If you are overcharging the system, it is best to take the vehicle to a mechanic to have the system properly drained by an air conditioning machine and thus wait for the correct amount.

    Why You Should Leave It To The Professionals

    There are various types of at-home A/C recharge kits on the market. However, adding new refrigerant without evacuating the old, potentially contaminated refrigerant won’t ensure that you are getting the best performance from your vehicle’s A/C system. Just topping off the refrigerant may or may not bring the cold air conditioning back and if it does bring the cold air back, the question will be for how long because the leak was never fixed. Without diagnosing the root cause of the problem, any benefit will be short term at best. Further, be aware that adding too much refrigerant can reduce the system’s cooling ability and potentially cause the whole system to shut off.

    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.

    What Is An A/c Recharge

    Is It Legal To Vent Old Refrigerant From Your A/c System Into The Air When Making Repairs To Your Vehicle

    Under former EPA rules, it was ILLEGAL for anyone to intentionally vent refrigerant from an A/C system into the air when servicing a vehicle. Professional repair shops are required to have refrigerant recovery machines. The machine must be hooked up to a vehicle BEFORE repairs are made to suck any residual refrigerant out of the system so that the vapors do not escape into the atmosphere when the A/C system is opened up to replace a component. The logic for doing this is to prevent older refrigerants such as R-12 that contain ozone depleting CFC compounds from getting into the atmosphere. It makes sense and is a good thing to do. But the EPA rules also applied to R-134a, which does not contain any CFCs and are not an ozone depleting threat. However, the rationale for also requiring R-134a to be recovered rather than vented is that it is a global warming gas, and therefore contributes to climate change. The EPA rules also require recovery of R-1234yf, but the rationale is less clear because R1234yf is neither an ozone depleting gas nor a global greenhouse gas.

    Obviously a DIYer has no access to a refrigerant recovery machine so the issue of whether or not is acceptable to vent refrigerant when repairing an A/C system is moot. People just do it anyway. Besides, if your A/C system has a leak, chances are most or all of the refrigerant has already leaked out so there is nothing left to vent.

    UPDATE: As of March 2020, the EPA has revised its venting and recovery rules.
