Keeping in mind that low freon in a closed system must mean a leak somewhere, most cooling/refrigeration techs have access to those parts and obviously are usually trained to install them properly. Have you eliminated all other possibilities for poor performance as well? The reason I ask is that it is not very often that this happens in my experience. It's not uncommon for it to run fine for 10-15 years when maintained properly.

Where do i recharge the ac on a 2006 trailblazer?

There are two lines, a high pressure and a low pressure line. The refrigerant is added to the low pressure line, often referred as the low side. There are charging ports on both lines, and if you are using a "kit" to charge your system, the low side is the thicker of the two lines. Also, the kit will not connect to the high side, but you still must exercise caution. If your system is empty, save your money and do not recharge until you have repaired the leak. This is a closed system and if you need to recharge than there is a leak. Also, if any air has entered the system, it must be removed before new refrigerant is added. If you are only down a little bit, you can add some then. See video for details, of ask your local auto parts store to help you. Good Luck!

Trying to recharge A/C system in 2003 Frontier CRew Cab. Do you have a diagram of system so I can locate high and low pressure lines.

To recharge A/C system in 2003 Frontier Crew Cab. Brother, don't concern yourself about the technical stuff of which is high or low pressure line. The refill/charge kit line will only fit on ONE of the 2 line fittings anyway. The line fittings I speak of are covered with a plastic cap like the one on your tire valve stem. Get your recharge kit from parts store, get mine from NAPA, with the line and a bottle of Freon. Find the charge fitting, usually on the passenger side under hood not far from firewall. Take the cap off and put it in your pocket. Open the kit, screw the piercing pin of the canister end out and put that end on the Freon canister. DON"T pierce the canister YET. Screw the other end on the charge fitting of your system and start the engine, turn on the AC on high, NOW pierce the canister top by screwing the knob/t-handle all the way in and then back it out half way. This will allow the Freon to escape the canister and the AC compressor will pull it into the system. Now, I've one trick for you. Before piercing the canister, get a small bucket of HOT water and have it there at the vehicle front. Soon as you pierce the canister and back the pin out half way, stick the canister into the hot water in the bucket. The heat will force ALL the Freon out of the canister till empty. Once empty, remove the kit line from the charge fitting on your vehicle, remove the canister from the kit line, trash the empty and hide the kit line where you can find it later, dump the water and put the bucket away, and go sit in the cool. One canister should take care of the recharge. If you put too much in from another full can, it may overcharge the system and still have no AC. That's just the nature of the beast. If it leaks down, get a leak detector kit from same place you got the recharge kit and find the leak. They also make a literal "Stop Leak" kit for AC systems too. Same place will have it. Brother, old school on this stuff. I figure things out quickly. There's no reason why this I told you won' work. It's what I do. Have fun Bro.

How do i recharge my ac on my 2003 sequoia

DIY people can buy a kit at the parts store and add a can or two if the system is just low.
The kit is a gauge and hose that connects to one of the service ports on the ac line and takes the cans of freon.
Freon gas is about minus 30 degrees coming out of the can.

How to add freon to my 57915-331 duo therm camper ac?

Normally that would be a closed/sealed system, not rechargeable, from the factory. Don't know what valve your seeing, unless someone has retrofitted it with valves for recharging prior to you purchasing it. I will say that quite often the reason for poor, or less cooling, than when new, is often due to simply needing a good cleaning of evaporator and condenser coils and fins. Has that been done lately?

How do you add refrigerant.

If you follow the lines coming from the A/c compressor, you will find a red cap on one line and a blue cap on the other line. The blue cap is the suction side. Remove the blue cap. You can buy recharge kits at the parts store that have a line and tap included. You just couple the line there, open the valve on the freon can and start the engine. Run the a/c on high. Be careful not to overcharge the system. If the belts start squeeling, that will indicate too much freon in the system and a high presure situation.

AC not blowing cold

Check to see if your AC compressor is turning, If it is then you need to refil system with freon equivalent thru the low pressure port. The kit you get will only let you put it on the low presure line. You can pick the lit up at any auto supply store. just folow the instructions on the kit. If the compressor clutch is not engaging check AC relay

My recharging kit for air conditioner doesn't seem to fit recharge valve on 2004 dodge durango. How can I be sure i am looking at the low prerssure valve?

Newer vehicle come with R134 vs R12. Since the two are not compatible, R134 has larger fittings. AC system has two ports, High and Low. Low is return to AC Compressor and high is output. High port is first following line from compressor to condenser (condenser is at front of vehicle like a second radiator). Keep following line till you find high port (paint cap red). Second port is low (paint cap blue).

How do I recharge the a/c in a 2006 impala ss

First you need to find the low side inlet valve. It will have a black or chrome valve cover that you just screw off. You will see two close to each other, the one you are looking for is the large one. You will need to purchase 134a freon from your local auto store or superstore. Be sure the hose has a gauge on it as overfilling is not a good thing, you could burst the system. Then you turn the air on Max ac and hook up the hose to the valve you found earlier. Then follow the directions on the can. If you need further help, please ask.

How do I recharge the AC freon on my own?

You should have R12 freon in a 1990 but you can put R134 freon into that system the only problem your going to have is the adapter for R12 is different from R134 after you get the adapter you need to put the freon in the low pressure valve not the high pressure, you will know which one because the adapter only fits the low pressure valve which is located on your AC lines under your hood, theres a little cap thats either blue or black you unscrew. You can't buy r12 anymore because its not good for enviorment so buy R134. you can buy at any parts store for like $5 to $10.

AC is not working

Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.
