How do you convert from r12 to134a


Recover R12 then flush system. Change drier or receiver tank depending what vehicle you have. Change expansion valve or orifice tube again depending what vehicle you have. Install the R134a Hi and Low service ports and put the correct amount of compressor oil for R134a freon into compressor. Pull unit into a vacume for about 15min. and leave it set for another 15 or 20min. to make sure it stays in a vacume and there are no leaks. If it holds a vacume charge the unit with the correct amount of R134a and run unit and check that it operates and cools properly. If all is good install the service port caps and your done.

My AC is having trouble. It seems to only work once out of every 50 times I have tried to run it. I checked the freon with a AC gauge I bought and followed the instructions and it said the levels were up...


Hi, first of all, you will want to verify that your compressor is kicking on. Open hood and located A/C compressor. Have a helper start the engine and and then turn on A/C to maximum with blower at full speed. See if you hear and observe the compressor kick on. The outer portion of the compressor outside the pulley is the clutch. It should make a click and begin to spin along with the pulley. If it kicks on ok, does your cooling fan at the radiator kick on also? May need to run the engine a few minutes to verify that. If so and you are reading a full charge at the low pressure port at this time, you have air in the system and it should be completely emptied and then re-filled with around 3 LBS of R134a refrigerant until you read a low pressure side of 45-50 PSI. Then you will be blowing cold air.

Air conditioner does not cool in 2000 Yukon.How do I check freon level and how to replace freon if need be


Get an r134a refrigerant add kit from Walmart or your local auto parts store.

You can even get a can of Arctic Freeze by Intermatics that has a hose and a gauge on it.

Connect the hose to the low side port. You can find this port on the 'thicker' piping that comes off of the compressor (versus the thinner piping that comes off the compressor which is the high pressure side).

Pressure should read 25 psi to 45 psi on the low pressure side when the compressor is running and the a/c is on.

Pressure should read 75 psi to 100 psi on a hot day when the car is off.

However, you'll want the a/c to be running when you add freon.

Press the button on the can to install more freon, if needed.

What kind of refrigerant does a 93 oldsmobile achieva need? Am I able to recharge it with R134a?


Why do people guess, this is what you need
93-92 Olds Achieva All Eng. ....... R-12 42.00 oz Mineral 8.00 oz
Vacumm the system to remove all moister and air (this is a must), I have converted many systems that were R12, with out change anything but the PORTS to allow R134 to charge the system and had no problems, always use high and low gauges, and a temp gauge inside the cars vents, this allows you to see what temp the air is coming out of the vents.
Add enough freon to bring the high side up to 150 psi, this will activate the cooling fan, check the inside temp. add a little at a time till the inside temp drops below 60 degrees, I have been able to get R134 down to 36 degrees, it depends on the systems condition. test drive and be cool.
Good luck

Air conditioner full of freon but not blowing cold air


Hi Friend:

#1) 1st Check to make sure your compressor is engaging (CYCLING) then possible theres a Leak in Your System/Or a Clogged up Expansion Valve,Very Common.Which is Located going to the Lines from the Firewall to your Evaporater.

#2) You'll need to Completly Discharge your Freon from your A/C System.Which should be Discharged in a Recovery Can.and not in the Air.

#3) And after the System needs to be Completly Evacuated ,which takes a A/C Suction Pump.If your Doing this yourself I'm not Sure if you Can Rent this Pump or Not.

#4) Since your A/C system is Now Empty after the Evacuation:I would have your A/C Flushed Out Completly.

#5) Lots of times it somehow gets some Foreign Material in it that Prevents the System From Working Correctly.

#6) Now start your Engine Turn your A/C on Maxx Cool and Run the Fan on High as well You'll need to add the Oil(PAG) that was lost during the Evaperation as well. If your doing you'll want to msake sure you buy R-34 With a Gauge.This Way the Gauge will indicate when its Full (In the Green area on Gauge)

#7) Now if ALL the Above has been Complted you Should have Cold Air in your Vehicle.Providind All other Components are working Right.

My air conditioner is not blowing out cold air. How much freon do I put in a 2000 GMC Sonoma ?


That all depends how much freon it still has in the system, best way to check is with some a/c gauges, if you put to much it will not cool or could damage some thing, and if not enough will not cool right, used a/c gauges for right amount of freon, now if the a/c system is empty it takes 1.88lbs of 134a freon.

How can i recharge the air conditioner? Where is the hose located?


Ok if you want to do a home repair in hopes of saving yourself a lot of money and with hopes your system is not in major trouble, here goes:
First step buy 3 types of 1 lb. cans of refrigerant R134a at a parts store, 1 can of leak detector freon combination, and if possible 1 can freon/air conditioning oil combination freon along with 1 can of straight r134a freon.
The store will sell you a charge hose with a cheap type of charge gauge attachment and fittings to attach to your system for the re-charge.
Providing your system is low on freon,First, with the vehicle running and the a/c on full cold, high fan, install the 1 lb. can of freon/oil combo first only charging through the low pressure side of the system never through the thin line high pressure side as the pressure from the high side can enter the cgharging freon can and explode it like a bomb,(this low side line is the larger hose and the low side charging hose fitting the parts store sells you will only screw onto the low side charge valve which is normally marked "low" on the top of the plastic dust cap that is factory installed(hand screwed) on the low side valve fitting.
Secondly after the oil/combo can is emptied into the low side and you of course are wearing mechanics hand protection gloves and eye protection googles, then and only then will you install the leak dector 1 lb. freon can combo.
Third you will install the last 1 lb can of r134a freon, however your vehicle will not allow the whole last pound of freon into its system by means of a pressure relief blow valve that will automatically blow off any excess pressure once the system over fills, the system typically holds approximately 2.75 lbs. of freon.
If you have successfully installed the above freon into the system it should be up and running providing the system is in fairly good working order, by that I mean it may have a very slow leak that allowed the freon tio originally escape in the first place causing you to refill it, and if it does have a leak the leak detector die that you installed into the system should leak out from wherever it may be escaping from, indicating the place of needed repair by means of a red or blue, or whatever other designated coloration the die gives out from the leaking area.
Please note: Not all home charging techniques typically work as there are many mechanical failure factors in an a/c system that may require a certified a/c technician to determine exactly why your system is not working should the home remedy fail.
I hope this helps you and remember to always work safe with eye and hand protection especially around freon gases which become extremely cold and can cause frost bite when contacting with the bare skin.

I have an 1992 grand marquis mercury the air condition is blowing but its not blowing as cold as it should. And it is also filled with freon.


compressors do get old & dryer/accumulators do get less efficient. if you have a poor cooling fan or cooling system those also can affect A/C performance, ovefull refridgerant system can also affect the performance. I would have a reputable shop inspect system performance & make sure you have the CORRECT amount & type of freon in the vehicle. If repairs are required make sure you upgrade to R134A . It's much less expensive & up to date.

How do i add the air coolant into my 1993 Ford


Hello,

You'll need a kit, available at Wal-Mart/Auto Zone/similar. The kit will contain a method of attaching a can of freon to a valve, a hose and gauge, a connection that puts the freon into your system. The freon goes into the Low pressure port, which is the larger line at your compressor, and the cap should have the letter "L" on the top of it. NEVER add freon to the high pressure port. It is on the smaller line and will have the letter "H" on the port cap.
When you take the low pressure cap off, there is a schrader valve (bicycle tube valve) under it. You'll connect a can of 134a to the manifold/valve in the kit, and fit the hose onto the low pressure valve. You screw the valve on the manifold all the way in to puncture the seal of the can, and then slowly open the valve to dispense the freon. Nothing to it. Now start your vehicle with the windows down, and the A/C set on high, with the fresh air option set to fresh (not on recirculate).
Get the type of kit that has the gauge built into it, so you do not wind up overfilling the system. Dispense the freon with the can valve up, so you don't put liquid freon into your compressor.
Then, watch the gauge until it gets in range. Close the valve on the can, shut your vehicle off. Remove the hose quickly to avoid freon loss. Replace the valve cap. Chill!
Your kit will come with instructions. Read them. Most kits do not come with freon. Buy two cans, three is better. You don't want to run out of refrigerant in the middle of charging the system and have to go get more.
You should have no trouble putting freon in your system. Just be mindful where you place your hands and equipment,and you'll do fine.

Best regards, --W/D--
