You asked: Does it matter what kind of freon you put in your car?

So, a good rule of thumb is if you own a vehicle that is newer than 1995 your engine should take R135a refrigerant, but if you have a vehicle older than 1995 you are going to be purchasing R12 refrigerant. If you are still concerned you might be using the wrong refrigerant, look under the hood.

Can you put the wrong Freon in your car?

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.

How do I know what kind of Freon my car needs?

There’s a sticker under the hood (Fig. 1), somewhere right up front, that tells you which refrigerant was used in the factory fill, and it also tells you how much. That sticker is part of SAE Standard J639, which provides safety and design standards for automotive air conditioning refrigerant systems.

Is all Freon the same for cars?

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.

What happens if you mix Freon types?

Indeed, mixed refrigerants can cause increased system pressures and temperatures, resulting in ineffective compressor cooling, reduced cooling, possible compressor damage, metering device malfunction, and inadequate oil return to the compressor, said Eugene Silberstein, director of technical education and standards, …

What happens if you put the wrong refrigerant in AC?

When using these types of propane refrigerants it is possible that they could combust when putting them in units where they are not designed. … This can cause great bodily harm, property damage, and in a severe case even death.

Can you mix 134a with R-22?

The different types of refrigerants are not meant to be mixed. The refrigerant charge must be optimized by using the refrigerant’s respective pressure-temperature chart. But when mixing an alternative refrigerant with R-22, there’s no pressure-temperature chart you can refer to.

Are all 134a refrigerant the same?

Are all R134a refrigerants the same? Yes, almost all the r134a refrigerants are the same. However, the properties of leak detection sometimes change in the refrigerant. So, you can use the leak detector.

Can I use R134a in a R1234yf system?

yes R1234yf Freon gas can be replaced by R134a; the newer systems were designed with this in mind so no, there will be no damage to the compressor but some time in the future doing so may become illegal. >>

Does R1234yf cool as good as R134a?

The results of this study have shown that the cooling capacity of R1234yf AAC system is significantly lower (between 5 to 25 %) than R134a system. In the experiment, the power of the compressor is slightly lower (up to 11 %) for refrigerant R1234yf compared to R134a inside the AAC system.

Can I buy Freon for my car?

If you’ve confirmed that your vehicle uses R-134 or R-1234yf, or has been converted from R-12, you can purchase a recharge kit which will include the recommended refrigerant, dispensable from a pressurized can of approximately 12 ounces to 22 ounces and in most cases will contain a reusable recharge hose outfitted with …

Are there different kinds of Freon?

There are 2 different types of air conditioning refrigerant currently used in residential cooling systems. R-22, commonly referred to a Freon and R410A, a blend considered to be more environmentally friendly, sometimes called Puron.

Can you mix R12 and R134a?

As previously stated, R12 systems usually use mineral oil, which is incompatible with R134a. When R134a comes into contact with mineral oil, it can hinder the oil from returning to the compressor, or possibly reduce heat transfer.

Can I mix R22 with R290?

Because R290 has similar saturated pressure-temperature characteristics and volumetric refrigerating capacity as R22, is miscible with the oils typically used in R22 compressors, is relatively cheap and is reported to yield favourable efficiency, it is often deemed as a desirable option to use in existing R22 systems.

Is R22 a freon?

If your home’s air conditioning unit is more than 10 years old, there’s a good chance it uses R22, commonly known as “Freon.” R22 is an A/C refrigerant — a substance used for cooling in air conditioners— that was once widely used in air conditioning units in homes and businesses alike.

Can you mix r438a with R22?

Mixing refrigerants is never recommended. However, based on the similar operating conditions of Freon™ MO99 and R-22, system damange would not be expected.
