What Happens If You Put Too Much Freon In A Car
Your cars air conditioning system immediately comes to your rescue if its scorching outside. However, what if your cars AC unit is not circulating cool air as its supposed to do? What are the possible reasons for the malfunctioning of the air conditioning unit?
Well, if youre not a mechanical engineer or dont have much knowledge about the same, you may not be able to conclude anything.
However, there is one thing even a novice like you can consider as the probable cause in this case. Thats overcharging your cars air conditioner with the freon gas. Its a compressed gas thats responsible for the cool air every AC unit throws out.
But its overcharging can produce negative results like the above one. Besides, below are other important things youd know about this magical gas and how it affects your car.
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.
Detecting Low Freon Levels In Cars Ac
Thecars AC system wont be able to maintain temperatures as low as it normallywould if the levels of freon are low.
There are a number of indicators that the freon levels are lower than they should be, and if you detect any of them it is a sign that you need to add freon to the ACs system. Lets take a look at some of the most common signs of low freon levels.

Whats The Difference Between R
You can say the difference is so big that it has spared the fate of the entire planet. Not to get all deep on your psyche and all, but after it was discovered that R-12 and a whole multitude of products containing Chlorofluorocarbons were destroying the ozone layer, environmental scientists immediately started work on an alternative cooling agents free of ozone depleting CFCs. That formula is R-134a: the standard and only refrigerant permitted in automotive A/C systems today.
R-134a, though safer, is not perfect:
Beginning in 2013, R-134a is being replaced by a new formula, HFO-1234yf, available on select U.S. car models. HFO-1234yf is the cleanest, safest refrigerant yet. And whats even more important is that it has been studied and certified as leaving no impact on the environment what-so-ever. Talk about a great advancement in A/C technology that will help protect our planet for all those driven to cruise the open roads for many years to come.
Preventing Car Air Conditioning Troubles
Thankfully, one essential routine maintenance service can help prevent vehicle air conditioning problemscabin air filter changes. Your cabin air filter captures dust, pollen, and other contaminants circulating through the air inside your car. When your filter becomes clogged, your AC system has to work harder to forced air through. This added stress can accelerate or create air conditioning troubles. Routine cabin air filter changes can help protect your system and keep you breathing cleaner air.

How Do I Know If My Car Ac Needs Recharging
In order to know when your car AC needs to be recharge, these are three most significant signs:
Air Conditioner Clutch wont Engage
Usually when the air conditioner reaches its maximum capacity, the clutch engaging starts to click and drivers can hear it very well. The reason for this is that the clutch engages with the AC pressure switchs signal in order to read the level of system pressure. For this purpose, when AC reaches low level, the pressure switch cannot activate, leading to no clutch engaging. This problem stops the system from circulating.
Cooling capability Decreases
One of the most famous symptoms that tells you the automobiles needs recharging is that the overall cooling capability dramatically drops. Why is this a clear signal? Since the system of air conditioning works by circulating a pressurized refrigerant, if the air is not blowing cold air at all, you need to charge your AC fast.
Signs of Refrigerant Leaks
Last but not least, there will be signs of refrigerant leakage. There will be greasy film on many AC fittings or components underneath the automobiles. If there is any, this might be a sign that you need to recharge your AC.
Listen For The A/c Clutch To Engage
When you turn on your vehicle’s air conditioner, if you listen closely, you will hear a ‘click’ which signifies the clutch engaging. If the Freon levels are too low, the clutch will fail to engage which means there’s not enough refrigerant for the compressor to pressurize. In other words, your air conditioning system has nothing to work with!

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.
Why Is My Car Ac Not Cold
The number one reason for your car air conditioner to blow air thats not cold is low refrigerant. Other common reasons are:
- Clutch Cycling Switch failure – Your refrigerant cant pressurize.
- Broken or blocked condenser – Warm air cant enter your AC system to be cooled.
- Blocked or kinked airflow – Cool air cant get into your cabin.
If you need an AC Recharge, youve come to the right place. If you need service on the rest of your AC system, Midas can help. Start by diagnosing the problem. Learn about our Car AC Repair service.

Is It Safe To Drive With Low Refrigerant
Driving with low refrigerant is safe in the short term, but letting it go too long can increase your repair cost when you finally have your AC serviced. Refrigerant not only cools your cabin air — it lubricates the seals in your AC system. Over time, the seals in your AC system can degrade from lack of lubrication.
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 Often Should You Change The Freon
There is nothing like an ideal time to change freon. Being a gas, it doesnt have any shelf life. Still, car experts recommend checking and changing freon every 12-15 years, although its still not necessary as long as everything is running fine.
It also means that if freon somehow escapes from the unit due to leaks, youd have to refill it no matter if all this happens before the stipulated 12-15 years or not.
While the working of an air conditioner is pretty the same you would have studied years back many people often ignore the freon in the process. Its the most important component of your cars air conditioning unit that blows out cool air from the air vents.
If its present in high or low quantities, the air conditioning unit will perform badly or even break down completely in the worst of scenarios. Thus, its proper quantity is a must.
Check The Compressor And Its Clutch
If the temperature is well above 21 degrees and the clutch is engaged, you may need to refill the refrigerant. If it is not engaged, it could mean the compressor is busted, or the clutch is not electrically activated, or the refrigerant level is too low. The next steps will determine which is the problem.

How To Recharge Your Car Air Conditioning
When your cars air conditioning begins to lose power and doesnt blow cool air, it may be time for an AC recharge. Recharging your AC means adding more refrigerant to your AC system to allow the air to start blowing cold again.
Important to know: recharging your AC is a temporary fix to a likely bigger problem. If your system is indeed missing refrigerant, your air conditioning system has a leak and needs to be inspected and repaired with a certified mechanic. Refrigerant does not evaporate in an airtight system, so air must be leaking in.
- Note: Some older vehicles cannot have their AC unit recharged. These vehicles generally fall before the year 1995 and use an R12 refrigerant no longer made. The only option is AC replacement.
Though an ac recharge can be completed at home, it is still considered a more professional repair, as it contains work with hazardous liquid and is best left for a certified mechanic.
Use The Additional Equipment
Before proceeding further into the steps involved in how to put freon in-car air conditioner, you have to make sure that you have worn the safety equipment like a pair of gloves and protective goggles.
You also must have a refrigerant dispenser to refill your cars AC system with freon. Some brands also sell refrigerant cans along with dispensers. But you need to pay close attention to its features before buying them. A model may not sometimes allow you to measure the pressure in the AC system.
The refrigerant dispenser must be equipped with both a trigger and a pressure gauge so that you can use it to monitor the pressure in the system while refilling the refrigerant. That is why it is important to purchase a refrigerant dispenser that will enable you to go through the entire process safely and effortlessly.

Connect The Dispenser To The Fill Port
You must stick to the instructions closely while attaching the dispenser to the fill port, and try to complete the entire process as quickly as possible. The first thing you will need to do is get a firm hold of the dispensers connector and then lift its outer sleeve.
Squeeze the trigger to remove all traces of air from the hose that connects the dispenser to the fill port and then push the connector to the fill port while still squeezing the trigger and holding the connectors sleeve.
Pressing the trigger ensures that an even flow of the refrigerant is coming out of the connector which reduced the chances of air or moisture reaching your cars AC system.
As soon as you release the sleeve the connector should fall in place, and then proceed to release the trigger. Double-check if the connector is correctly positioned on the fill port before you start recharging the AC system.
How Often Do I Need My A/c System Recharged
Only when the cool breeze no longer feels as chilly as you remember. Simple enough. Now, it is true that a well maintained A/C system can go its entire life without needing a recharge. But, thats if youre extremely lucky.
If you start noticing your A/C isnt reaching those refreshingly cool temperatures, have your system inspected. In this situation, most cars will be low on Freon. And since the A/C is a sealed system, low Freon is a big sign that something is not right. It could be a small leak that needs attention or possibly part of the A/C is failing bring it in and well perform an A/C Performance Check and get to the root of the problem. Well get you back out there cruising with a nice, cool breeze again.

How Many Cans Of Freon Does A Car Hold
Under the hood, you will see the engine and engine components there, and you will find a label that will tell you how many cans of Freon your car can hold. Most of the cars need R134a refrigerant for their air conditioning. How many cans of Freon for a car depends on the size of a cars AC system. Average a car can hold three cans.
New Restrictions For Selling R
For entities selling or distributing refrigerants for use in motor vehicles, there will be new restrictions for R-134a and other substitute refrigerants sold after Jan. 1, 2018. The rule establishes certification requirements for buying large containers of refrigerant and mandates that small containers include a self-sealing valve.
Under the new requirements, anyone purchasing a substitute refrigerant for R-12 in a greater-than-two-pound container must provide the seller with evidence that the technician has a Section 609 Technician Certification. If the purchaser is not certified and is buying the refrigerant on behalf of a service facility, the seller must be presented with evidence that one or more technicians at the facility are certified.
Refrigerant wholesalers must retain an invoice listing the name of the purchaser, date of sale and quantity purchased. The wholesaler is not required to confirm any technician certification, but EPA is recommending that wholesalers obtain a statement certifying that the cylinders are to be resold to certified technicians.

We All Know How Hot The Texan Heat Can Be
The Texan heat is tough on air conditioning systems, and during the summer months, the last thing you want is to head out for a long drive only to realize your vehicle’s air conditioning is not working. The chemical used to provide cool air is called Freon. Without it, there’s no way to circulate cold air throughout your vehicle cabin.

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 wont ensure that you are getting the best performance from your vehicles 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 systems cooling ability and potentially cause the whole system to shut off.
