you have to be certified to get r12 and its very expensive.... you can convert it to r134a for $32 at advance... it comes with 3 cans and the gauge

how exaclt does it convert it. is comes with everything or r u just talkin about buying the refrigerant at advance. cause i believe u have to change some valves or things in the system and it usually cost like 400 bucks to do so plz explain

alright here is what you need to do.
get ALL of the old (r-12) out of the system. by the "retrofit" kit i think they run like 7 or 8 bucks. then do some research and find out what kind and how much PAG oil you will need. (the standard i think is like 1 oz per unit) then add r-134a until the gauge reads full. a can of refriderant is like 8 bucks and the gauge is like 4 or 5 i think. but if you have a leak you can by what they call a all-in-one where it will have your PAG OIL your r-134a and some stop leak.

the retrofit kit, what is involved with changing the parts to work with r134a cause i know u cant just dump it in a r12 system. but i would think changeing the parts to work might be a little involved. i did find this stuff called freeze12 which is suposed to be a direct replacemtn for r12 systems no converting like on r134a stuff. and its farily cheap. please someone give some kind of step by step on the process of converting to the new stuff if u know how. i have never touched a/c stuff before, also where do i get one of these retrofit kits

The retrofit kit is simply o rings and changing the refridgerant and oil. O rings compatible with R-134a are supposed to be blue and not black.

nope the retrofit kit is changing the high and low side ports to the 134a size.

the o rings is a different story some you'll have to replace some will handle it i don't know why but if you have the time and can i would replace the o rings while i was doing all this.

rgaynor85

where are these high and low ports and these o rings located usally and how hard are they to change. and when i wanna buy it do i just go to autozone or sumthin and ask for a retrofit/conversion kit

rgaynor85

ok ive read a little more into it, i see the high and low ports are the valves that u put the stuf in by i get that now. i also understand the retrofit kits has the adapter valves to hook up the new cans to the valves. so is that really all thats involved is suking out the old **** and changing those valves and pumping some r134a in there?

or you can tell your technician to use freeze 12. its a replacement for r-12 and works pretty good.
