What fluid is for car AC?

Typically referred to by the DuPont trade name Freon, the most common Freons are R-12, R-134A, and soon, HFO-1234yf. Freon is pretty similar to motor oil and radiator coolant in that it is a working fluid designed for a specific system; In this case, your car's A/C system.

Does car AC need coolant?

An A/C system is a closed system, and if there are no problems, coolant is not consumed by the vehicle, nor does it escape. Unless your auto's A/C is in need of repair, there is no need to “top off” the system.

Can I add Freon to my car myself?

You've likely run low on refrigerant in your A/C system. Over time, tiny amounts of refrigerant leak from the lines, degrading A/C performance. The solution is simple - put more back in. Recharging your air conditioner yourself is inexpensive and can be completed in just a few minutes.

Can I recharge my car AC myself?

Topping off a car ac system can usually put you back in the deep freeze. That's a job you can do yourself if your vehicle was made after 1993 and is filled with R-134a refrigerant (check the label under the hood or the specifications section of your owner's manual to be sure).

Is Freon and coolant the same?

Key Differences Between Coolant and Freon

Instead, coolant is designed to keep your engine cool and will remain in a liquid state within its system. On the other hand, Freon is a gas that is converted into a liquid and then back into a gas before creating the cool air you feel in the cabin when your car's A/C is on.

What type of AC recharge do I need?

The most common refrigerant is R-134A (or HFC-134a) however newer vehicles may use R-1234YF (or HFO-1234yf). Even still, some very old vehicles may also be using R-12 (or Freon). The easiest way to know is to check your vehicles A/C system nameplate under the hood.

Do all cars use R134a?

Selected for its low flammability and safety, as well as because it's kinder to the environment, almost every car built since 1994 is equipped with R134 refrigerant.

How do I know if my car is R-12 or R134a?

To tell if it has been converted you can look for a sticker on the unit under the hood, which would indicate that it is R134a. And you can also look for R134a adapters, which would be located on the charge parts.

Which coolant is used in AC?

R-134a. This coolant is used in many different refrigeration and air conditioning systems around the world. Because it is a hydro-fluorocarbon (HFC), it doesn't cause ozone depletion, as older coolants did. It is the first non-ozone-depleting fluorocarbon coolant to have been successfully commercialized.

How much is it to put Freon in a car?

It is recommended that this service be performed on a vehicle every 100,000 miles or so. You can save on your this cost by going the DIY route and recharging your car's AC, in which case you can expect to pay $40-60 for a proper recharge kit.

Will antifreeze make my AC work?

How much does it cost to refill AC coolant?

Most homeowners will pay in the range of $200 to $400 for a refill, depending on the type and size of their HVAC unit. If you own a larger r22 unit, you may have to spend $600 or more.

How much does a can of Freon cost?

Freon costs an average of $150 for a Freon refill. Most people pay between $100 and $350 for a refill, depending on the size and type of your HVAC unit. Older large r22 units can reach $600 or more.

Why is my AC not blowing cold air in my car?

The most common cause of a vehicle's air conditioner not getting cold enough is that it needs to be recharged. You can recharge your refrigerant by yourself, but to save time and make sure the job is done correctly you should make an appointment with your local professional auto shop.

So, along with R134a came a new oil: Polyalkylene Glycol—or PAG oil. Note that there is another kind of oil called Polyol Ester Oil (POE). The advantage of ester oil is that it works with both R12 as well as R134a, so you can fill the system with it and then use either refrigerant.

What type of oil do you use with R134a?

Polyolester oil is a type of synthetic oil that is compatible with the R-134a, R-410A and R-12 refrigerants. Experts say it is a good substitute for hydrofluorocarbons.

What happens if AC compressor has no oil?

Without enough oil in the crankcase to properly lubricate the load-bearing surfaces, wearing and scoring happen. There just isn't enough refrigerant mass flow in the system to return oil to the compressor as fast as it is pumped out. Without enough oil, those surfaces become visibly scored or worn.

Can you still buy R12 refrigerant?

Anyone with the required EPA R-12 certification still can buy the 1-pound cans at auto-parts stores, but the cans are kept in the back and guarded like gold.

Can you replace R134a with R12?

Mixing R12 and R-134a refrigerants is illegal, and even if you previously bleed out the R12, the system has to be adjusted to use R-134a, or it will cause leaks, copper corrosion, and lack the lubrication required for optimal operation.
