First check that this is not an electrical fault. If it is an electrical compressor, check the supply and measure ohm value of the coils.

If the compressor is running, but not cooling, you have probably run out of gas.
Near or on the compressor will be a redundant pipe. It should have a valve on it, but sometimes for cheapness it's just cut off after filling.
There needs to be a valve fitted on the system for it to be refilled. You may have to buy one and braze it on the pipe yourself.

After this first hurdle, most vehicle spares suppliers now have kits for replacing vehicle refrigerant - complete with hose, pressure gauge etc . Just fill a little, and check for leaks, then fill up and test.

Thanks for using fixya!

Isn't blowing cold air, clened coils, removed, dirt, leaves, but still no cold air. Seems to be low on Freon. How do I get the unit charged?


The compressor needs to run, does it run? If it runs and the outdoor radiator is not producing heat, then it may be low on refrigerant. The compressor refrigerant lines, the skinny gets hot and the thick line gets cold under normal operation.
To recharge the unit, it needs to be leak checked and repair any leaks found, then recharged. The refrigerant type used needs to be known, a manifold gage set is used to diagnose and recharge.
If you have a window unit, you should have it serviced or replaced.

New compressor about 6 months, and A.C its not working anymore


That fact that it was repaired 6 months ago makes me think the service tech may have left a very small leak in the joints of the tubing where he installed the compressor. If I'm correct the freon leaked out. The leak will need to be located--repaired and the freon recharged. This is just one possibility. Something else may have gone bad but if it is running and not getting cold my guess is probably correct.

I had bought a Lg inverter wall mounted unit it worked about 3 days but it didnt cooled the area and i decieded to changed the outdoor unit(compressor)according to repairman's advice .during the first...


You changed the compressor?? Why ??? These models do not normally have problems with this. I am conversant with most of the LS series and these have capacitor start compressors, which fail all the time. Generally all models have either a 45 /6 uf or a 50 /6 uf capacitor. If this fails, the compressor wont start, thus a no heat, no cool problem. If you have changed the compressor and made sure it is actually running, what is the operating pressure?? Suction side should be around 0 to -5 degrees c. Perhaps there isnt any gas in the system??
I assume by doing such a repair you are licensed to do so and have all the proper equipment to recharge the system ???

Quit cooling.fridge and freezer b


You need to check the Condenser coils, these are copper coils of tubing usually located on the back of the unit near the ground. They need to be free of all dust and grease to work at maximumefficiencyand it is recommended to clean them every 6 to 10 months. If those coils are already clean, the next thing to do is check the evaporator fan(The fan inside the unit). See if it's running. If it's not, check the coils behind it. If the coils are frozen up then you probably have to change out the fan motor.If they aren't frozen up then there may be a refrigerant leak or a bad compressor*. In order to legally reclaim, recharge, or test refrigerants you need a special certification2_bing.gif from the EPA. If you need to do so I recommend you call in a certified technician.
If the lights, fans, and compressor aren't working at all, check your fuse/breaker box to see if anything is tripped or blown.
*To replace the compressor you need to reclaim and recharge the refrigerants from the system.

Compressor keeps running. Hasn't shut off in last


Good chance your FREON or refrigerant has developed a leak. To save money, put your unit in the back of your truck or trailer and take it to a REFER shop and have the Sealed System Checked. They will tell you if it can be recharged or if you Compressor has died. If the compressor has died, generally it means the unit is too expensive to fix. Reason, the cost is high, the recapture of the GAS before it is recharged in expensive, the compressor is expensive, and the recharging is expensive and then putting a new compressor in a older refer could put a lot of pressure on a group of existing old parts... well then, the weakest link will generally break... Not always, but if one does, then your into a older refere and stuck with pouring more money into older unit.. Sorta like pouring money into a hole in the water... They call that a boat... Hummmmm Good luck.... e8dcb4e.gif

Cool but not cold air from my ac system


It sounds simple enough that you need to recharge your A/C unit. They can stop functioning properly after winter's end especially if they were not used. You should be able to get a recharge kit from your local auto parts store. Your Suburban should use the newer R142a refrigerant.

My air is blowing warm can i use 1342a?


The real answer to your question is yes, the kit may work. Here is why you shouldn't use a recharge kit: Theoretically, your vehicle's refrigerant (R134a) should last forever. Your AC system is a sealed unit and the refrigerant never gets used up. The only way you can lose refrigerant is by it leaking out of the system. However, if your refrigerant can leak out then air and contaminates can get in. This is bad. A recharge kit simply injects refrigerant into the system. It doesn't evacuate the system of any air and contaminates.This is critical. Your AC system should be hooked up to an AC machine in order to evacuate out all of the air and contaminates in the system. The machine will then hold a vacuum on the system to verify its integrity.Finally, the machine is able to inject new compressor oil that also contains a dye that will enable the leak to be located. If you use that recharge kit, you stand the chance of over pressurizing the AC system and causing premature compressor failure. This can be very expensive. Paying a reputable shop to evacuate and recharge your AC system is much less expensive. If your AC system hasn't operated in over 6 months, it's especially critical that you have the repair to your AC system performed correctly. Your AC system's seals may have dried out and the new compressor oil will be critical in helping to recondition those seals or the seals may need to be replaced. Good luck and hope this helps. keep me posted if you need help to recharge the system.
