2000 GMC Yukon air conditioner how to replace and what do I need to do


How have you deemed that it is a faulty "air conditioner", and not an AC system that is just low or depleted of Freon and needs recharged? If it is truly a bad AC motor/pump, we are talking about recovering the Freon from the system, which is complicated and requires training in its own, and then replacing the physical part, and then recharging the system accurately and properly.
Typically something better left to trained professionals and not made for the DIY home mechanic.

How do I release the freon to change out the compressor


You should take it to an AC recovery service. If you get caught dispensing freon improperly, you could get over a 10000 fine. After it's recovered, you can work on the sysyem. Make sure you create a vacuum on the system prior to recharging your AC with freon.

Well, If you want to do the job correctly, you need to properly recover the freon and then evacuate the system before recharging. Failure to do so is ILLEGAL for the recovery part. EPA laws forbid knowingly releasing freon into the atmosphere. There are some hefty fines to pay if the authorities were to find out. Not to mention that I really don't appreciate people who knowingly and willingly pollute the air that I breath. - take that as you will.

For the evacuation part, failure to properly evacuate your system before recharging will leave moisture in the system that can destroy your new compressor. If that happens, you won't be saving any money!The air that is left in the system will take up room in the system that is needed for a proper freon charge and can adversely affect how well your system cools when you are finished.

Here is a possible alternative. Take it to a shop just for recovery and evacuation. The labor charges will not be that much. In fact, some shops will do the recovery for free if you tell them they can just keep any freon that is recovered. You need to do a recovery to remove the freon from the system anyway so nothing blows up in your face when you disconnect system components. Then you can return to the shop after replacing the compressor and drier fo an evacuation. This is a good idea also because the system can be checked for leaks by evacuating and seing if the system holds vacuum. That way you won't be wasting any freon dumping it into a leaking system.
Then you can recharge the system yourself using one of the kits available at your local parts store.

Hello Scott,Your new ac is OVERCHARGED with freon.Shut it off,let it cool down and recover/remove freon.The compressor has an internal pressure valve that makes the (hiss).It will stop when the charge is adjusted.Call them back to do it.

I have a 94 lumina van tha ac pull is shot how do i get the pump off to just put a pully on it


The freon has to be recovered before removing the a/c compressor.There is a special machine that does this.You can not just remove the hoses.They are under pressure and if you get freon in your eyes you could go blind.You can have a shop recover the system and then you can remove the compressor and then fix it but you need special tools to remove the pulley also.Then once you have it back together you can have them recharge it.On some of these they give you enough room to remove the pulley without taking the compressor off.Hope this helps.Good luck.

My ac does not work at low rpm, when you get the rpm's up the ac


If there is air in the system you will need to recover all of the refrigerant (freon) from the system this is done with a machine called a recovery unit.Then the system will need evacuated this is done with a vacuum pump putting the system in a vacuum will remove moisture and air from the system,the epa requires a minimum of 4" of vacuum for MVAC (motor vehicle air conditioning). If you are not familiar with this you need to take it to someone who has the proper equipment for this type of work. Air is one possible cause, other things that cause this are: a malfunctioning expansion valve, a dirty condensing coil (located in front of the radiator),a faulty clutch fan will not pull enough air across the condensing coil at an idle, if the system is low on freon,and if the low pressure switch is malfunctioning.I strongly suggest you take it to some one who has been trained or is experienced in trouble shooting ac systems.I hope this information is useful if you have any other questions don't hesitate to ask.

Ac compressor took one can of freon will not take other also it still is not cool


You may have over charged the system, An over charged system will also give you poor A/C performance and worst can lead to expensive repair if the compressor get's damaged.
 With the AC on the coldest setting, use a thermometer in a middle vent. Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience. If normal gauge readings are obtained and the vent air is cold - STOP don’t overcharge the system. The only proper way to remove refrigerant is with a AC recovery machine so if this is being done at home I can’t emphasize enough not to over charge the system. And actually the best way to insure the proper charge is in a system, is to use an AC machine to recover the freon and then evacuate and recharge the system with the correct amount. Most cars have the specified amount on a decal under the hood. 
Normal readings on high and low side with AC OFF (static pressure) - Depends on outside temperature, but normally is between 80-105 PSI
Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s - Ranges from 25-35 PSI - Note that on many Chrysler products a normal reading on the low side may be 15-25 PSI
Normal high side reading ranges from 200-350 PSI

Don’t assume that if adding little Freon is good that adding a lot is better!  Overcharging just a little can decrease the performance of the system and possibly damage the compressor.

God luck and hope this helps.

the a/c system needs a minimum pressure before the system will run. the system must have a leak so just buying freon may last a day or a few months depending on the size of the leak. also leaking freon into the air is ozone depleating, it should be recovered properly.

the system needs to be recoved of all freon. vacuum to -30psi held checked for leaks. (uv dye or nitrogen and soapy water). leaks fixed. vacuum to evacuate moisture and air. refilled with proper amount of freon (too much or too little make the air not as cold).
