NO! You would never put propane in an air conditioning system! For air conditioning to work it needs FREON. Depending on your car you need to find out what kind of freon it requires, as well.
134a there a tag that says how much or system holds if you have rear air its more
Older vehicles took R-12 freon and the newer vehicles take R134a freon.......
The evaporative air cooler is an alternative to conventional central air conditioning. An evaporative air cooling system is more economical to operate than a conventional central air conditioning unit.
Freon but you can convert over to the new stuff
All air conditioning units use Freon, a chemical that when circulated helps to keep air cool. The kind of freon used in both devices is not the same, and chemical solutions with different amounts of each are needed to get the job done.
R134
FREON!! but you can convert it to R-132a. Buy a kit on any auto parts dealer.
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.
central
Go to Walmart or an auto parts store. Buy an a/c recharge kit for R134 freon coolent. Follow the directions on the can..
