How do I replace the freon in my portable A/C unit?

you can't unless you put a saddle valve on it to hook up a hose for the gauges to put the Freon in it. If it needs Freon you have a leak somewhere. When you put the Freon in it will leak out this is why you need to find the leak.

I'm trying to put freon in my car and it won't take it... What can the problem be?

To put freon in the system,the vehicle has to be running and turn the ac to max. it may take 5 minutes or so per can . if it still won't take it ,the valve where you are refilling could be bad or after you put the hose on the can of freon you have to unscrew the t handle screw that is used to puncture the can to release the freon through the hose.

When putting freon in my 01 saturn there is a high input valve and a low input valve, which one do i put the refrigerant in/

You put the freon on the low side, it may have a blue cap to let you know its the suction side.

its usually closer to a long round canister called the dryer or accumulator. when putting freon

make sure to run your ac on high while you are recharging the ac. good luck!

you can buy a saddle valve, this is a valve you screw in. I am assuming you have the correct freon as where you purchased your freon they should sell the saddle valve. Hope this helped

I need to add 134 to the system, it's not blowing cold

First of all, you need to check if the belt is tight, if the electric clutch is turing on and off with the switch, and if there are bubbles in the receiver/dryer cylinder sight glass.
If you add so much freon that the pump has liquid in it, it could blow it up.

But you buy freon with a short hose and valve.
Wear eye protection and gloves.
Then you attach the can to the valve on the side with the thick hose.
There will also be a valve on the skinny side hose, but do not attach freon there. That is only for measuring with a gauge.
The open the freon valve and start the engine and AC.
If the can frosts up, you can put it in a bowl of warm water.
Watch the sight glass until the bubbles stop.
Then close the freon valve.
Turn off the engine and AC.
Disconnect freon can.

How do i add the air coolant into my 1993 Ford


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--
