What is the correct pressure for freon in AC unit and what is the color of the cap where you add the freon?????


The charging port cap is usually blue, The charging fixture hose will not clip onto the wrong port, so you really can't mess that up. the pressure of a system as measured on the low side hose should be about 28-32 PSI with the system stabilized and engine at operating temperature.

How can I put freon in my window air conditioner?


First you have to get a piercing valve and install it on the suction line. Then hook up your guages to see what the pressures are doing. If it needs freon you charge it through the piercing valve. They dont come with any access to the refrigeration system. let me know if I can further assist.

My air conditioner quit cooling. i was going to add freon but cannot find the low pressure port. it has 2 ports on the same line and my fill tool will not fit but one. the freon will not go in.


The ports are keyed - you found the proper port if you have the proper hose. If the Freon will not go in - and you have complied with all the package instructions ... right? ... Freon is not your problem. Going much beyond what you have done already is dangerous. Please have your AC looked at by a licensed AC Service Mechanic.

Thank you for your question @ FixYa.com

Need to add 'freon' to my samsung window unit.


Hello, in order to add freon to a window unit you must add a piercing valve to then low side of the system. The valve mounts to the suction line and allows you to connect your gauges and add freon. Here is a link to where you can purchase piering valves. http://www.hvacr-tools.com/mm5/merchant.mvc?Screen=PROD&Store_Code=HVACR&Product_Code=BPV31&Category_Code=VALVES

Do you add freon to your indoor unit or your outdoor unit? I have A new 2 ton first co unit indoors unsure what I have outside. Where does the freon go?


I would highly recommend that you get a friend or hire a pro, to deal with this. You dont just add freon, is it -R22 or the new 410A type? You always charge a system from the outdoor unit! If this is a new outdoor condensor, it will be pre charged for the unit, indoor coil and roughly 15 to 25 foot of line set. But after the brazing is done,,, NEVER SOLDERING! You need to use a Vac-Pump and pull the indoor coil and lineset down to 500 microns, before you open the king valves.
If this outdoor unit was used, then does i match the indoor coil? In sizing and type of refrigerant? Need to reclaim the existig refrigerant, pull a deep vacummn on the whole system and then weigh the charge in, according to the tag on the outdoor unit. You should have a CFC license t work with any type of refrigerant, if someone turned you in, it starts with a $ 10,000.00 fine for a start, You need allof the right type of tools and knowlege, save time and money,,,, get a CFC licensed tech,he will know all of this.
Sincerely,
Paul

My 2008 F250 w/ auto air conditing will only blow hot air after the truck is out in the sun for a short time when it is cool in the morning it works fine..


YOU NEED TO ADD MORE FREON TO THE UNIT. SOUNDS LIKE IT NEEDS TOPPING OFF. YOU CAN BUY R-134A FREON IN A PACKAGE WITH A HOSE AT A PARTS STORE. DON'T KNOW HOW TO CHARGE THE UNIT , NO PROBLEM. OPEN HOOD, START TRUCK,TURN A/C TO MAX WITH BOTH DOORS OPEN RUNNING AT
NORMAL SPEED, NO REVING, THEN FIND A BLACK METAL PIPE
RUNNING FROM A SILVER DEVICE CALLED AN ACCUMULATOR.
THE PIPE WILL HAVE A CONNECTOR, JUST UNSCREW THE CAP
AND PLACE FREON HOSE WITH THE CAN CONNECTED TO IT AND
SECURE THE END OVER THE PORT VALVE. OPEN FREON VALVE ON THE CAN AND PLACE UPRIGHT AND LET IT SIT. WHILE INSTALLING THE FREON, FEEL THE VENTS BY THE DOORS OR
DASH TO SEE IF THEY ARE GETTING COLDER. WHEN THE VENTS ARE COLD YOU CAN TURN THE VALVE OFF ON THE FREON CAN
AND DISCONNECT IT FROM THE FITTING AND PLACE THE CAP
BACK ON THE VALVE. THAT'S ALL THERE IS TO IT. YOU CAN ASK THE PARTS STORE CLERK WHICH PORT IS FOR CHARGING THE UNIT IF YOUR UNSURE. THEY ALSO SELL R-134A FREON WITH A
SEALANT MIXED IN WITH THE CAN JUST IN CASE YOUR UNIT MAY HAVE A LEAK IN THE SYSTEM. REMEMBER, **NO REVING** NO
MATTER WHAT ANYONE SAYS. THE SYSTEM WILL NOT CHARGE FASTER. IF YOU WANT FASTER CHARGING THEN KEEP THE CAN WARM. FREON WORKS WITH AMBIENT TEMPERATURE WHICH
MEANS WARM DAY OR CAN IS FASTER THAN A COLD DAY AND
A COLD CAN. FREON MOVES FASTER WHEN HEATED.

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--

Duo therm 13.5 does not cool


Hello, W/D here.

Some models are equipped with charging ports, some are not. If your's doesn't have them, there is a service port that bolts on to the tubing, and the tubing is then punctured, giving you service ports. This is an easy add-on fix, and not expensive. I believe that all of the rooftop A/Cs are R22 refrigerant, so, yes, special tools and a license are required to assess the unit. If the fan/compressor works without cooling, it should be seen by a qualified technician. They can diagnose any issues, and add refrigerant if required. If you are actually low on refrigerant, you have a leak somewhere. If you system has recharging valves, it can be as simple as a valve stem leaking. As for you question regarding a relay, I doubt that this is the issue, as the fan and compressor are controlled by the relay's action, and sound like they work.

Best regards, W/D
