is freon still used in air conditioning?
Answers:
Freon is Du Pont's brand name for some refrigerants. In answer to your question yes they are still using R-22 (one of Du Pont's original refrigerants) in air conditioners but not in automotive units. R-12 is the refrigerant that has been deemed hazardous to the environment and was used in auto a/c units. R-12 is not manufactured anymore in the U.S. and many other countries.
R-22 is classified as a HCFC (hydro chloro floro carbon) and R-12 is classified as a CFC (chloro floro carbon). The only difference between the two is one molecule of chlorine. R-12 = dichlorodifloromethane R-22 = chlorodifloromethane. The extra molecule of chlorine in the R-12 makes it more environmentally hazardous because it is unstable and when dissipated into the atmosphere can mix with the ozone breaking the ozone down into oxygen and chlorine oxide.
There have been many types of refrigerant developed in the last decade to take the place of the CFC and HCFC refrigerants. R-134a is what most manufacturers of household refrigerators and auto a/c units have gone to in place of R-12 R409a is another refrigerant used and there are many other new refrigerants for other applications
For anyone to work with any refrigerant they must be licensed by the E.P.A. and be able to recover the refrigerant from the devices using refrigerant when needed while working on them so the refrigerant does not get released into the atmosphere

yes it is,they say they have ozone friendly freon. but who knows

Yes in older units, the newer units use "Puron", I think that's the name. Always hire a professional to work on your refrigerant needs, EPA issues.
Yes it is. I think you have to have some kind of license to use though.
You're right, freon is no longer used. There is another gas, but I don't know what it's called. Some people still refer to it as freon because that's what we know.
R22, the common refrigerant in home use, will no longer be made in 2007.
There is no replacement that can be used in existing units.
Puron is scheduled to be the main one in use.
expect the cost of re-charging your home unit to skyrocket.
Yes it is. The word "freon" has been used for decades as a generic term when referring to the refrigerant chemicals used in air conditioners, refrigerators, coolers, etc... Today there are more "ozone friendly" refrigerants (freons) due to government regulations. Also, "Puron" is the name that the Carrier Corporation uses to identify the R-410A type of refrigerant in it's products. Other companies use R-410A, too. There's the short answer. Hope it helps.
There is a modified version now in use, actually for about five years now.
You can tell in newer cars and wall air conditioners.( not as cold)It is supposed to be more enviromentally friendly, but it is required to be contained and recaptured like the old freon???
The refrigerant used for residential air conditioning for many years has been R-22, commonly known as Freon. Due to a concern that the chlorine in R-22 Freon was harming the ozone layer, it began a gradual phase-out many years ago. The next phase is in 2010 when no new equipment can be made with it.
The replacment for R-22 Freon is R-410a Freon. Although R-410a is sold under a variety of trade names, including Puron, each one of them is R-410a Freon. It does not have chlorine in it so presumably it will not damage the ozone layer.
This replacement works well but cannot be used in older R-22 systems. Anyone replacing their air conditioning system should certainly use the new refrigerant.
There are many different gases used for refrigeration. Even ammonia can and has been used though it's corrosive nature has put a stop to it.
