Reason #: Stop Leak Can Cause Damage
The delicate components of your car’s A/C compressor and other aspects of the system can sustain damage from the stop leak included in most DIY A/C recharge kits.
In order to plug up small leaks in the system that may have leaked refrigerant, a stop leak compound is included in these kits. It’s designed to fill small leaks so that your car’s AC system won’t leak any more refrigerant. But it often has unintended consequences! These compounds generally won’t fix major leaks, while excess stop leak can gum up the works of your AC system. Evacuating stop leak from the system can be a major hassle, and some auto shops may even refuse to work on a car that’s had stop leak put into the system!
A little bit of refrigerant will leak out of an A/C system that’s working properly. If there’s a major leak, it should be professionally repaired with the right parts. A DIY kit is only a temporary fix that’s likely to make matters even worse over time.
Overcharging Car Ac Is The Most Common Mistake
DIYers think that adding extra refrigerant will make their system pump out colder air. WRONG. Refrigerant R-134a isnt very forgiving whether the system is undercharged or overcharged. In fact, if you add as little at 2-ounces beyond recommended capacity, you can decrease cooling by almost 50%.
These DIY kits attach to the low pressure line and recommend adding refrigerant until the dial gauge needle appears in the green zone. Charging a car AC system by is NEVER an accurate way to get the right charge. If done properly with a manifold gauge set, a known amount of ram air and an ambient temperature gauge, a professional technician can get close to the right charge. The technician would attach a gauge to both the high and low pressure lines, measure shop temperature, outlet temperature and temperatures going into and out of the evaporator. Using all those pressures and temperatures, a pro can calculate how the system is working and whether it has the right charge. However, the ONLY way to get an accurate charge is to evacuate the system and add refrigerant by weight.
Can you get the right charge using a DIY kit? Close, but not exact. Overcharge or undercharge and youre going to get warm air.

How Often Does Car Ac Need To Be Recharged
Last Updated on February 17, 2021 by Eddie Westheimer
So, youve decided to prepare for the summer heat? Brilliant! Having no AC on a hot summers day is absolute torture. You can avoid this sweaty situation by taking action early and maintaining your cars AC system.
If youve noticed that the air coming from your AC vents isnt as chilly as youd like for it to be, you might be wondering if its time for a recharge. But how often does car AC actually need to be recharged?
In this article, well take a look at the cars AC system learn how it works, possible faults, the reason behind them, and find out how often your car AC needs to be recharged.
How Ac Leaks Form
Leaks mainly form due to oxidation of the aluminum parts of the AC system. The most vulnerable part of the AC system is the condenser, which is located at the front of the car. Because the condenser is located at the front of the car its susceptible to damage from rocks, road salts, and moisture. Oxidation is especially common in places that are poorly vented and covered.

Reason #: It Could Be Incompatible With Your Car
If your car is particularly old or new, it’s possible your car is incompatible with DIY A/C recharge canisters commonly found at auto parts stores.
Those cans typically use a mixture of R134a refrigerant, compressor oil and a leak stopping compound. Many classic cars built before 1994 use R12 refrigerant instead. Mixing refrigerant types is never a good idea, and can cause unintended consequences. In fact, the resulting mixture is so volatile it could damage the equipment used in professional A/C service — and many auto shops will refuse to work on cars that have had the wrong refrigerant put in.
What’s more, many modern cars aren’t compatible with these at-home recharge kits either. Some newer cars are equipped with a new, more environmentally friendly R1234yf refrigerant. And most hybrid and electric cars use a different type of A/C compressor which requires a different kind of oil. On these cars, it’s best to leave the A/C maintenance to the pros.
Reason #: Improper Recharging
Even if your car is compatible with refrigerant recharge kits and it doesn’t have any major leaks, there’s one fatal flaw in these devices: they don’t measure the amount of refrigerant going into the system.
Sure, there’s a gauge at the top that indicates the pressure in the system — but that’s not an accurate way to determine if the right amount of refrigerant is in the system. Refrigerant gas is measured by weight, not pressure. To properly recharge a car’s A/C system, the entire system must be evacuated to remove any remaining refrigerant and any excess moisture. Then, the right amount of refrigerant is added — by weight — and the system pressure tested on both the high and low side of the system.
These cheap DIY kits only measure the pressure on one side of the system, meaning it’s easy to accidentally overcharge the air conditioner. An overcharged system will blow hot instead of cold, and will need to be serviced by a professional to safely remove excess refrigerant from your car. What a nightmare! That’s why we think it’s better to get professional A/C service the first time instead of using cheap refrigerant recharge kits.

How Often To Recharge The Car Air Conditioner
Recharging the AC on a car is not a regular maintenance item on your cars manufacturer recommended maintenance schedule. In theory, the system is sealed, and you should never need to do this. In practice, however, rubber seals dry up and wear out, and refrigerant slowly evaporates over time, leaving not enough left in the system for the air conditioner to work effectively. Other components can fail as well, but attempting a recharge is the first thing you should try, particularly since this is often all it needs to start working again.
Your A/c Is Blowing Warm Air
One of the most obvious symptoms of low Freon levels is if your air conditioner is blowing warm or room temperature air. As we discussed, the air conditioning system in your vehicle operates by circulating this pressurized refrigerant. When the amount drops too low, it eventually affects performance.

Added Freon Still Not Cold
If your cars AC isnt blowing cold air it might be low on refrigerant. In most cases you can recharge car AC systems yourself with a can of refrigerant, a charging hose and gauge from any auto parts store. But what if youve followed the directions on the can of refrigerant and your car AC is still not cold? Well, lets take a look at the most common do it yourself mistakes, along with other possible causes.
What Is An A/c Recharge
During a car A/C recharge, your A/C system’s old refrigerant is evacuated and replaced with new refrigerant to help ensure your air conditioning system is operating properly and keeping you comfortable.

Heres How The Ac System Of A Car Works In Better Detail:
The system uses a special refrigerant gas R134a and is divided into the high-pressure side and the low-pressure side.
Low-pressure R134a refrigerant vapor enters the compressor and gets compressed into high pressure and high-temperature R134a vapor. The vapor that also contains special lubricant oil is circulated into the condenser . As the high temperature and high-pressure vapor travels through the condenser, the heat is released into the much cooler ambient air. While the vapor is cooling down and passing through the condenser tubes, it condenses into a liquid . This high temperature and high-pressure liquid travels through the filter drier and onto the small orifice of the expansion valve. This valve provides a restriction against which the compressor pushes.
When the liquid refrigerant passes through the expansion valve, its pressure lowers and so does its temperature. Now its a low pressure and low-temperature vapor. Next, the refrigerant passes through the evaporator. The hot air of the cabin is being blown through the evaporator, thus cooling the air of the cabin down. Then, the R134a refrigerant is pulled back into the compressor and the cycle begins again.

Because of the sensitivity of this procedure, we will explain how to use the AC recharge kits. They have shown to be the most effective and safest option in comparison to trying to repeat a mechanics role at home.
- Meat thermometer
- Refrigerant .
Safety glasses and gloves
Tip: Always wear safety glasses when performing work under the hood. It is especially important to be careful to not get any refrigerant on your skin as it freezes quickly and is very painful. Please be sure to follow all instructions that are included with your AC recharge kit and read every canisters warnings carefully.
Step 1: Turn on your AC. Start your car and turn your AC to Max or High.
Step 2: Determine if AC compressor is engaging. An AC compressor is a device driven by the accessory belt that converts the refrigerant from liquid to gas. The compressor has a clutch at the end of it that should be spinning with the accessory belt when the AC is on high. Look for these pulleys moving.
Step 3: Test the pressure. To test the pressure, turn the vehicle off and locate the low side pressure port. The low side pressure service port is generally located on the passenger side of the engine bay. It will have a black or grey cap on it with the letter L.
- Tip: If you are having a hard time finding it, try locating the two aluminum pipes that are coming out of the firewall and trace the larger-diameter pipe until you find the service port.
- Proceed until you are as close to 40 psi as possible.

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.

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.
What Is Recharging The Car Air Conditioner
Before you recharge the AC on a car, its important to understand how your AC works and whats involved with this repair. Your air conditioning system uses a special refrigerant called R134a to remove moisture from the air inside your car and deposit it outside. This process cools the air as the moisture is removed, and the blower brings cool air into the cabin.
Over time, this refrigerant can escape, either through normal evaporation or through leaks that form in your system. Without refrigerant, the AC can no longer move moisture from the inside to the outside of your car.
Recharging the AC is simply the process of adding more refrigerant to the system. It needs to be at a certain level, not too little, not too much, in order to work properly. A recharge kit is really just a can of R134a refrigerant with a little bit of leak sealer mixed in, a hose that connects it to your car, and a gauge to measure how much of it is in your car. These recharge kits are available for $20 to $50 in any auto parts store and are easy to use. The average cost for an AC recharge at a mechanic is between $123 and $155, so you can save a lot of time and money by doing it yourself.

What Is An Ac Recharge
Simply put, an AC recharge means adding more refrigerant to your vehicle. This process is a very common maintenance requirement for older vehicles that still use Freon as a refrigerant. Most modern cars have started using a refrigerant called R134a instead, which doesnt need to be topped off quite as often. If you have a new vehicle that commonly needs more refrigerant, theres a good chance you have an AC leak somewhere in the system. Either way, well get to the root of the problem and help you stay cool on the road.
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!
