Question about Heating & Cooling

1 Answer

Machine is spewing freon into the used oil reserviour when vehicle system is put under vacuum. Recently changed the filter drier and vacuum pump oil with no problems and have used it a couple times since with no problems. Just before this problem arose, we took a few leaking fittings apart and cleaned them. Coincidence?

I am assuming when you refer to machine, you are actually refering to a vacuum pump?

Not clear what you are referring too on this one. Can you provide more details?

How to change the drier acumulator tank


This is not something that you should do. It requires special tools and equipment. You need to remove the Freon and capture it. Also remove the oil that is in the system. Then you check the Orifice tube and replace the part. You then put the oil back in and vacuum the air out of the system for several hours. Then you put the Freon back in.

I change the receiver drier in my `1997 jimmy I have to pour oilin the receiver ?


Well you can.
Normally, you would run a vac pump to pull all of the air out of the system, then allow the vac to pull oil back into the system before you add freon. But if you don't use a vac pump, you'll have to add oil before you hook everything up.
Make sure you cycle the compressor a few times before you start adding freon if you don't use a vac pump.

What do I do when I change A/C compressor on 2001 Ford Expedition Eddie Bauer


No, don't add any Freon before changing out compressor.

Unfortunately, due to the multiple places where leaks can occur, and the concern of releasing Freon into the atmosphere when opening up an air conditioning system, this work SHOULD be done by qualified personnel with appropriate tools. Auto air conditioning is NOT in the realm of "Do It Yourself" any longer.

It would be best if, after installing the new compressor, you took the vehicle to an auto center that services auto air conditioners. They can draw a vacuum into the system before filling the system with Freon. This will give you the best fill with Freon and will reduce and/or eliminate condensation in the system.

Also, if you're opening the system to air anyway, to change the compressor, you should consider changing the drier in the air conditioner line as well.

Converting the r12 system


To convert from r12 to r134a freon, you first need to have the r12 discharged into a recovery system by a licensed professional. It is a violation of federal law in addition to environmentally irresponsible to vent this gas to the atmosphere. Next, remove the drier from the a/c system and use a spray can of a/c system flushing solvent to flush the oil r12 refrigerant and lubricating oil from the system by spraying into one of the liberated hose ends and placing a catch bucket under the other hose end.
You will need to purchase and install a set of adapters for the high and low side access valves by simply screwing them tightly and securely on top of your old r12 valves which are already in place.
After cleaning the system, replace the drier with a new one and reassemble the system. Evacuate the system to a sufficiently low pressure using an HVAC vacuum pump and then add the recommended amount of r134a freon and lubricating oil to the system through the charging hose on your combination manifold gauge set. Assuming of course that you didn't have leaks in the system before you began the conversion, you should now be good to go!
Good luck, and Stay Cool!

Fridge not cooling. Shifted house 2 days back. Before it was alright.


Your fridge systems under chocked. Whenever transport refrigerant unit you should not lift down wards on suction side which will lead compressor oil thr' discharge line. When compressor on, it will pump the oil.It get chocked on filter drier resulting to no cool.

Solution. Remove all gas, and also filter drier. Now flush out condenser side separate and evaporator side separately.Then replace filter drier and vacuum the system.Now do gas charging. Thanks. helpful?

My father passed away leaving me a 1991 linc town car. Air seems to work but does not blow cold. I know he never converted to new freon. could a simple conversion be the solution?


It is possible. It the problem is the compressor. It would be good to change the compressor, drier, and orifice tube. You will also need the conversion kit for the fittings. All of this can easily be bought at the auto parts store. Be sure to vacuum the system and add oil and the freaon. Changing over in the long run will be cheaper, plus you can always buy your own freon, where as leaving it R12, soemone else will need to do it for you and it will cost quite a bit for the freon. In order to convert, compressor, drier, orifice tube, oil, and freon will be about $210. Not a bad investment.

Car a/c works ok for 10 minutes then compressor shuts down.


Hi, what's the pressure on the high side and low side, there could be a restriction in your system, and if there's you can tell by looking at high and low side pressure, restriction could be cause by ice build up in your system, dirty filter drier, or just plain dust. sometimes driers go bad, and you will need to replace it, vacuum, and recharge, but if that's not your problem, check high & low pressure switch, they are normally located on both lines, trace coming from compressor, until you locate switches, they usually have two wires coming from them, they are design to cut compressor off, when pressure is high or low, replace, don't bridge them, are you sure you don't need more freon, trace liquid line (hot one) to condenser in front of vehicle, somewhere along that line, you will find filter drier, usually filter drier has a glass on top of it, where you can see freon passes through it, start your a/c if you're seeing bubbles in there, you need more freon, if glass is clear then it's full. (O.K) good luck.

DEAD AC COMPRESSOR


Remove and save the freon gas using a recovery machine. Use a torch to remove the high and low side tubing from the old compressor. remove the old compressor ans connect another in its place. Install a new filter drier. Remove the air from the system with a vacuum pump and and recharge the system using guages and new freon. Fairly simple but as you can see a lot of specialty equipment is needed. You cannot buy the freon without a card, and noboody in the business is going to be willing to sell you a compressor if you are not in the business.
