Freon 12 is a compound.
Some freon does leave a powder but most does not. This powder was most commonly found in older freon used in an earlier time.
Freon. In most of them nowadays, it is Freon 134-A.
"Freon" is DuPont's trademark for its CFC refrigerant products. R-22 is one of those refrigerants, so R-22 and Freon-22 are the same refrigerant.
Freon is not toxic unless enough of it is drank. It will not kill a human to inhale it, but it might cause dizziness or nausea.
Freon was replaced by other refrigerants long ago.
Freon does not generally need to be replaced. However over time, systems sometimes have a small leak and need to have coolant added. A Freon gauge can confirm if you need to have Freon added.
It replaced R-12 and Freon as a refrigerant. It is not always compatible with the old R-12 or Freon systems though, so check with the vehicle's dealer about compatibility and/or conversion.
134a replaced R12 about 1995.
The 1988 Pontiac Bonneville originally used R12 freon, this freon is no longer available due to government regulation. Your A/C system must have it's A/C service ports replaced. Then the system filled with the correct amount of R134a freon.
Obtain ASE certification in heating and AC systems.
Never! If it's low on refrigerant it has leaked.
The freon has to be removed and the pressure released from the ac system. Then the valve can be removed and replaced. The system will need to have a vacuum pulled and freon put in again.
RV refrigerators do not use freon but rather ammonia. The ammonia is in a sealed unit called the cooling unit and you cannot add ammonia to this unit. If it goes bad it has to be replaced.
You can still use only the heater if you want to but its best not to leave the a/c without freon and oil in the system..............
This is something that needs to be done by a professional, because the a/c system needs to have the freon removed prior to taking the lines loose. They can remove the freon and store it while the hose is being replaced and then put the same freon back in.
you dont considering you replaced the condensor and opened up the pressure in the system. It needs to be taken to a shop that can vacumn out the system so it will take all the freon it needs. If you do not do this, you ac will be half as cold.
