Is it absolutely necessary to evacuate the system to swap the compressor? Will relieving the pressure be enough to take out the old compressor?

If you want it to work. Removing air and moisture is critical to proper a/c function. Also, having air/moisture contamination can lead to "Black Death" a horrible sludge of aluminum, oil, water black crap that will ruin a system for ever. By all means, just charge it with Walmart Freon in a can. It makes it more profitable for the pro who has to fix it. Also, if the compressor has disintegrated, an in-line filter in the suction line will be necessary.

I'm just talking out my ass, I really don't know anything about mobile climate control.

To remove the compressor in a pressurized system, you need to UN-pressurize it. If you are going to install a new compressor and want the A/C to work properly, it will need to be evacuated and repressurized. There is a lot more...

no,it is not ABSOLUTELY NECCESSARY to pull a vacuum/evacuate the system when you swap a compressor out,as long as the system has not been left open for a long period of time,so that air&moisture has a chance to get inside the lines,but it will work a little better if you do.

you can also just purge the system,though,to force any air that has gotten in the lines out by leaving a fitting on the far end of the charging loop open until some of the freeon you are putting in starts coming back out,which will push anything that is already in the lines out.
that is called positive pressure evacuation,instead of negative pressure evacuation.[pulling a vacuum on the system]
i only recommend that method if you are using an enviornmentally friendly form of freeon,though,like R-134a.

My system is good ..it blows cold air but the pulley bearing has given out and making that annoying squeak.
it's a 2002 accord so I'm sure its R-134a ...so you're saying I can relieve the pressure from either low or high hoses ...so the hiss is minimal on the compressor end when I take it out?

If you do not evacuate the refrigerant and you continue to take lines off, you have 150 psi and around 3LBS of A/C refrigerant (R134A) that is going to BLOW out and all into the air around you and your face. People die from this stupidity. I can 100% guarantee you will be going to the hospital if you proceed without evacuating the system.

Certified technician and have my EPA 609 Certification. Also, releasing A/C refrigerant into the air on purpose like that is a nice $10,000 fine.

I appreciate the bragging but i need facts and boy you got your facts wrong end up....there's less 2 pounds of refrigerant in this car and pressure tops at 50 psi ...get your money back from whoever you bought that certification from....

Don't worry I know all about the laws and fines associated with this project....google is my friend and you certainly don't qualify to dispense this sort of judgment.

You are a moron and I do this every day for a living and have been for 5 years now. The low side will run around 35psi when operating so when it's running. The high side is around 200psi when running. When off the low side will be around ambient temp so here in fl that's somewhere around 100ps when it's OFF. You sir have no clue what you are talking about as well as everyone else commenting. Continue to do what you want and enjoy the trip to the hospital. A/c refrigerant in a vehicle will run anywhere from 1.5lbs to over 4 in something like a diesel pickup. Average is around 3

609 certification also has NOTHING to do with a vehicle itself. It's simply a certification that you need to work on a/c systems legally, and to purchase AC refrigerant. Not those cans you buy at napa or wherever that's filled halfway with sealer. Everything I have said so far is 100% accurate and correct. Maybe you need to learn how to use google.

You are the dumbass asking a common sense question about needing to evacuate an AC system before compressor removal. If you know so much how come you don't know something they teach the first day of high school automotive. Like I said before. Venting refrigerant into the atmosphere is a $10,000 fine

So bottom lines you're saying its absolutely necessary to evacuate system to change the compressor? That's evacuate, meaning everything inside the system...compressor condensers and all that ...50bucks at jiffy lube ...refill at another 50 bucks ...is that about right?

Plain and simple:
Evacuating system removes moisture and puts a negative atmosphere in system. In turn it creates a clean and proper environment for freon to be pulled into by negative atmosphere. Which will make your A/C blow colder.
You don't have to evacuate system but you do have to depressurize before starting any work.
You should also replace dryer when replacing anything with A/C systems.
Evacuating system is for after repairs to prepare a dry environment for freon.

Thank you ...that's what I'm asking ....I'm just replacing the compressor because the pulley bearing has failed ....it blows cold air and the clutch engages its just squicky noisy when turned on otherwise the system is fine. You're saying I still have to replace the dryer?

You don't have to but anytime you open an A/C system it is recommended to replace dryer. It's just good sense to do it. Plus most dryers only run about $40.

No by installing a new dryer it does not compensate for evacuating system. Evacuating system does more then just drying the humidity out of air as i already stated.
Look at it this way. If you take an empty squirt bottle and squeeze it then stick nozzle in water. When you release the bottle it then pulls water inside filling negative pressure. Well when you evacuate system it pulls freon in to fill negative pressure you created by evacuating system. Instead of trying to force freon in with positive pressure. Thus in turn gives you better fluid transfer and colder a/c.

Most garages that work on a/c will reclaim freon with their machine and pay you for it or recharge system at a discount.
Thanks for dumping freon into our environment.

Actually R134a is classified by the EPA as none ozone depleting refrigerant that's why its available to the public at large. R12 the older version of freon is ozone depleting although both are classified under regulation 608 the R134a poses no danger to the environment but for blanket purposes it is classified as environmentally toxic.

And that's not true most shops charges you $50 to evacuate your freon.

Well here in Fl. there lots of shops that will buy it. As far as safe for environment no freon is. That is why it is against the law to dump it freely into the environment. But do as you please you don't have to deal with the effects it has on the environment your kids will.

That may be so in Florida but they're talking about older freon version R12 and its nowhere close to R134a which non-toxic,non-ozone depleting and non-corrosive which is why they use it for aerosols we use today. Crying wolf about something you don't know doesn't help anybody.but do what you think will save your children there's no harm in that.
