Can I use R22 instead of R12?

R12 and R22 are two refrigerating agents for air conditioning units. R12 was once used in many air conditioning units as a refrigerant or cooling agent. However, it was found to be a very bad gas for the environment. But R22 is almost equally damaging.

Can R22 be used in a R12 system?

They are two completely different refrigerants,won't mix at all. But when it blows your system have the decency to tell the service tech what ya did. I have a R12 in basement for long time. I just use it few time for my old car (but the car was gone for ten years) so I think it has a lot left.

What refrigerant can be used in place of R12?

There are three replacement refrigerant options for R12 systems: R134a, R401a, R401b. R134a is regarded, by manufacturers and adherents to the Montreal Protocols alike, as the best replacement refrigerant.

Can you put R22 refrigerant in a car?

R22 refrigerant has been used for years in central air conditioners, heat pumps, mini-splits, car AC systems, and other refrigeration equipment. It's the key to absorbing and removing heat from a space.

Is Freon 12 and R12 same?

Refrigerant R12 or Freon 12 is said to be the most widely used of all the refrigerants being used for different applications. The chemical name of refrigerant R12 is dichlorodifluoromethane and its chemical formula is CCl2F2.

Using Propane instead of R12?

What is a drop in replacement for R12?

RS-24 is a “Drop-in” alternative for R12 which also provides a long term solution at the same time. It provides, therefore, a one change solution to the replacement of R12 at minimal expense.

Is R12 better than R22?

R12 and R22 are two refrigerating agents for air conditioning units. R12 was once used in many air conditioning units as a refrigerant or cooling agent. However, it was found to be a very bad gas for the environment. But R22 is almost equally damaging.

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.

What happens if you use the wrong refrigerant?

You cannot mix refrigerant types, and putting the wrong refrigerant in your car will cause damage to the air conditioning system! If you're not sure which kind of refrigerant your vehicle takes, DIY A/C charging may not be for you.

Can you mix refrigerants?

The short-long-only answer is no, never. There are many reasons why it's impractical, illegal, and not economical for a homeowner to mix refrigerant types. CFC-type refrigerants like R-22 – the most popular in the United States by far – are a single type of refrigerant. CFC stands for chlorofluorocarbons.

Can you top off R12 with R134a?

No. Federal law prohibits topping off an R12 system with a different refrigerant. Your options are to locate some R12, however you must be certified to purchase, and add it with an R-12 recharge hose.

What happens if I put 134a in 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.

Can you reuse recovered refrigerant?

Once reclaimed, the refrigerant can be recycled, which means oils and debris are removed from the refrigerant so that it can be reused. Recycling can be performed at the service site, but the refrigerant must reenter the original equipment it was initially extracted from.

Can you mix car AC refrigerants?

In short: no, it's not a good idea to mix different automotive air conditioning refrigerants. Your vehicle's HVAC system is designed for a specific kind of refrigerant, so adding another kind may cause the system to become damaged.

What are the symptoms of an overcharged AC system?

The likely symptoms of an overcharged AC are poor cooling, no air coming out of the wents, weird noises from the engine bay, and check engine light turning on. Because the AC coolant is toxic, fixing an overcharged AC is a job for a professional AC mechanic.

Can you put too much Freon in an AC unit?

Having too much refrigerant in your AC can damage the compressor. This can happen because the excess refrigerant will likely collect inside the compressor and cause subcooling, wherein temperatures are below normal. Furthermore, the extra refrigerant can flood the compressor and damage its mechanical parts.

Is R12 still manufactured?

International manufacturing of new R12 ceased in 1996, but existing R12 can still be reclaimed and purified.

Can you buy R12 in Mexico?

Re: Is there a legal source for R12

Go to the local HVAC supply house, they'll sell it to you and it's completely legal. Certain requirements apply, but it's legal. If you don't have a license, Mexico is probably the closest to buy it legally. Technically illegal, but it often pops up on Craigslist.

Is R12 a high pressure refrigerant?

– r12 refrigerant properties

R12 condenses at a moderate pressure under normal atmospheric temperature, has a boiling point of -29°C.

What Freon can replace R22?

The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22.

Will r134 work in a R22 system?

However, units made after 2010 can use R22 alternatives such as R410A, R134A, R407C, and R407A. These refrigerants cool just as effectively as R22 without the ozone depleting features, and they have an acceptable Global Warming Potential (GWP).
