Yes you can but take the car to an HVAC repair shop or auto shop that does repairs and have them remove the coolant first. Then when you are done have them refill it if they are willing to do that. You need a license to purchase refrigerant nowadays anyway. The shop will likely want to leak test your work unless you are a pro or have leak detection equipment for the refrigerant you will use. I don't know about scams but Freon was the original CFC and is made with Fluorine AND Chlorine which are two very dangerous chemicals R134 is made without Fluorine. Fluorine in the environment makes Hydrofluoric acid which can dissolve glass and flesh with abandon It is truly nasty stuff relatively speaking. R12 may have worked a bit better but it was ozone depletive AND dangerous to manufacture. R12 is still available but is very expensive . To discourage the kind of opem air venting that was the way in the pastt. Refrigerants can be evacuated from chillers and reused

    Just a note for Andrew- Shortly after R134 was widely introduced, I noticed that it too had a warning label that stated that it was a danger to the upper atmosphere- I still believe that the manufacturers (Dow and DuPont) simply wanted to sell a bunch more coolant than they had so pushed for the ozone depletion ban on the too-cheap Freon.
    BTW, the largest buyer of the remaining common formulation was the federal government since they didn't want the expense of a changeover. This caused the availability to shorten to weeks instead of years.

Replacing the compressor is strictly a mechanical task but recharging the system isn't and if there is still coolant in the system, it shouldn't be vented into ambient air.
Although Dupont managed to get the old coolant type banned, they only did it so they could sell us the new stuff (R134) which, for some reason, ALSO says on the containers that it STILL shouldn't be released into the atmosphere. The whole change was a scam perpetrated on us by collusion between the EPA and Dupont.

2006 Dodge Ram Mega Cab 1500 4x4 needs AC Improvment Can I upgrade the AC Compressor to get better preformance


Compressor change should have no effect, presuming it is working correctly. Have a qualified shop diagnose the system, there are tons of items involved, pressures, tempratures, heating system, etc. Remember that you are heating OUTSIDE air unless you are using recirculation setting...Hard to lower outside air to cool during the short time that the air is in the evaporator coils.

99 dodge ram 1500 ac problem


recharge your system, it;s low on refrigerat, there is not enough liquid going into the evap to help maintain cooling, hence the speed of the compressor. install gauges to check pressures at idle, if not to spec , recharge. if it's low you have a leak to repair. also make sure your AC condenser is clear. GOOD LUCK. RDJRP

I need to retrofit and recharge my 1988 Dodge Ram Ac.


First, the old R-12 must be completely evacuated fromt the system. R-12 and R-134A do not mix and won't function together. Once you are sure there's no R-12 left in the system, you need to install an R-134A fill valve on the low side AC line. This is where your refill hose will connect to add R-134A. Once the valve is in place you're ready to fill the system. The compressor requires a minimum of 20psi to engage and should not be filled to more than 45psi.

RECHARGING AC SYSTEM

1.Turn the truck on and turn AC on HIGH
2.Locate the low side AC line (will have a valve and cap similar to the cap on a tire)
3.Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet)
4.Insert the other end of the refill hose to the low side valve
5.Puncture the R-134A can with the screw on the refill hose
6.You should feel the system suction the refrigerant out of the can
7.Check for frost on the AC lines and the air blowing inside the truck
8.If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective
Hopefully this answers your question and you're able to get your AC working again. Best of luck.

On my 1995 Dodge Ram When I turn the A/C On it dosent seem to kick in and get cold just warm air?


In most cases, the problem is the system is low on refrigerant. The AC compressor requires a minimum of 20psi of refrigerant to turn on. There are refill kits available at the auto parts stores. If doing this yourself, select a kit that includes compressor oil, and a refill hose.

RECHARGING AC SYSTEM

  1. Turn the truck on and turn AC on HIGH
  2. Locate the low side AC line (will have a valve and cap similar to the cap on a tire)
  3. Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet)
  4. Insert the other end of the refill hose to the low side valve
  5. Puncture the R-134A can with the screw on the refill hose
  6. You should feel the system suction the refrigerant out of the can
  7. Check for frost on the AC lines and the air blowing inside the truck
  8. If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective
Hopefully this answers your question and you're able to get your AC working again. Best of luck.

Dodge Ram AC not blowing cold


By pass both pressure switches one at a time with small wire or a paper clip. If comperssor kicks on replace the swich that you bypassed.
if not it could be the fan clutch ot the compressor. Compressor runs about $400.00

Air conditioning not blowing cool air


To get the refrigerant in you have to have a technician purge the system first. Hope that helps.
