AC Compressor My A/C Compressor is not starting. My Mechanic says he has to flush nitrogen into it, remove the gas inside and then try starting it.He did this and then topped up the gas, Now he is charging me heavily for the topped up Gas. Is it right what he did to start the compressor? My compressor was fully loaded with gas prior to the service.

Does not sound right to me.My guess after doing what every he was doing he probably installed a start capacitor or repaired a burnt wrie, got the compressor running and charged for a lot of guess work. Just guessing.

I put a new compressor kit in my 2000 hyundai sonata 2.5 an it won't get below 65 degress in the cab

after you replaced the compressor,did you vacuum it down to remove any outside air in the system?(Better yet did you use Nitrogen to dry the system???)then vacuum down and then hold vacuum for at least 5 minutes per EPA specs? if the compressor kit isnt made for the unit(After-Market) within specs it will not last due to the tolerances of the old compressor with new part installed and will let in outside air enter and destroy the internal compressor components and leak out the new charge of R-134a refrigerant anyway

My fridge won't get cold. It seems like the generator is working, but it won't get cold.

I think, it's compressor noise. When gas leak, it will start pumping oil inside the compressor. When oil pumped, due to lack of lubrication,the compressor will make noise. Leak test, arrest, system flush out, vacuum and do gas charging. Helpful?

Helo I am muhammad iqbal i fill gas in unit after few mints its chowked i fix the new gas filter in out door unit and clean all gas systam out door unit also have problam

Dear Iqbal! Remove filter drier again. And flush out with Nitrogen. Now, Braze filter drier and then vacuum minimum 1 hour. Close valves and break the vacuum by charging little freon, say 80psi in ideal.
Run the unit and start gas charging till return good and back pressure 60 psi @ 98 degree ambient.
Now, the unit will survive for longer period further, provided servicing the unit periodically. Helpful?

I just put a new compressor in with a reversing valve aswell I put a suction drier and a liquid line drier on.I flushed the system with proflush and nitrogen. this system is 4 yrs old I didnt put it in im...

Hello Sometimes there is a SCREEN in the liquid line just b4 the piston in the tube.You had a SEVERE burnout the filter driers are shot from doing there job even with the short run time.Also you could try pulling the piston out and blow out the cap tubes in the evap.Close the suction service valve and pressurize the pipe and let it blow out the piston holder ot help clear those tiny tubes.Use a OVERSIZE liquid drier this time,Get a 10 ton drier or better.

My scope on my rifle is foggy on the inside

You can try to clear this your self. You will need a good sized clear plastic bag, say kitchen trash can size. You will need to get your hands on some nitrogen gas or you can also use carbon dioxide gas. You will need some good electrical contact grease or Vaseline will also work. Take the focus lens off your scope, let it dry out a day or so. Now ck for any o-rings and try to find new if you can, put the grease on the screw threads. Put all the scope parts in the bag and pump up the bag with your nitrogen and tie off the bag but leave room so you can screw the lens back on once it has set for a little bit in the gas. This should let gas stay inside the scope so no moisture can get back inside to fog it up. Try that, sounds crazy but it will work.

99 Toyota Tacoma a/c reads high pressure on low pressure side

Does the compressor run?
Low side could be high without a running compressor.

A running compressor?
The expansion valve itself is about $50 and bolts in.
You will have to remove the 134a gas before installing a replacement expansion valve and vacuum the system before recharging.

When your compressor on heatpump burns out how do you clean the system before installing new compressor

Flush the system with Nitrogen. Then R-11. Then install low side and high side filter driers. Then replace the low side filter drier after 2 weeks running time.

AC system's lubrication amount?

The oil spec is PAG 150--68.00 ounces. General Motors issues Bulletin # 02-01-39-004B replacing PAG 150 oil with a lower viscocity oil. Thus, now indicates PAG 46 (P46D) oil for those vehicles.
There is a high pressure side and low pressure side to the system. The high vapor=compressor to the condensor. Low side vapor=compressor to evaporator. Your system will use R134a freon.

The A/C is a sealed system and when the compressor fails it circulates debris throughout the A/C system and contaminates it. Before replacing the compressor several other A/C parts have to be checked or changed.
Typically, the condenser should be flushed to remove any debris or contaminated compressor oil. Use approved flushing agents (aresol or liquid pour types), that evaporate quickly and don't leave any residue in the system. You will also need access to 'DRY' compressed air or nitrogen to push the flush through the system. Nitrogen (an inert gas), is best because it doesn't introduce moisture into the system. You need to do this a couple of times.
Accumulator or receiver drier should be replaced when you are replacing your A/C compressor. If don't replace your accumulator or drier you will probably void your compressor warranty. It's virtually mandintory to replace the orifice tube or expansion valve. The openings are usually about .050" and are quickly plugged. Be sure to clean all hose assemblies internally prior to installing your new compressor. Not doing this could contaminate your new compressor. Flush both ways until the flush agent exiting is clean, you will need to remove the hose assemblies to do this.
After you have cleaned, inspected and replaced all the parts, you connect the vacuum pump and remove the air from the system. Make sure it holds pressure. Then recharge the system with the proper freon and oil to the system specified levels.

No matter why you are replacing the A/C compressor there is a lot of other related work that has to be completed before you install the new compressor. Hope this helps, good luck.

2 ton sanyo suction pressure erratic

Your suction pressure is erratic, your max. pressure is to much high. You did not measure your unit current reading liquid line press. to complete the data. But the problem of your unit is not the compressor its the system. Try to reprocess the system flush the unit with nitrogen, isolate the capillary tube and flush it with nitrogen to insure that no restriction.
