Just went through this. A new drier and orifice is required to keep your new compressors' warranty.

 

Soe great info , thanks! Videos very helpfu as well. Will pick up a vac pump and a manifold set this week.
thank you, C

 

Yeah. I wouldn't make you buy them, but I probably wouldn't warranty your pump either if that was the case.

They can hold lots of dirt.

 

For the price your going to pay for all the tools, you can get your system charged.

 

Just where exactly would this "dirt" have come from?

 

the tools aren't expensive. and they ARE reusable. all you need is a vacuum pump and a gauge manifold. nowhere near the 4 grand you seem to have paid.

 

Got some parts coming tomorrow, how do I remove the liquid line to replace orifice tube? Is it like the fuel line fittings?
Thank you, C

 

i think i have a total of $400 in tools for AC repair.

i also have MACS section 609 certification so i can legally buy
R-12 and recycle R-134 freon.

 

Open lines let in dirt.

Always check for metal shavings in the orifice tube.

 

Yeah, I know. I went to school for HVAC.
I decided not to do it because I didn't want to spend 4k on tools to just get started.

yeah, you can buy cheap tools and get the job done.

 

I'm certified to level 4 I think is what it is.
It was a few years ago, I dont' remember anything on it anymore.
The questions for the test were so silly. haha.

Is what I used to disconnect the line. Worked great.

 

Was the original question of, how do i recharge my a/c, ever answered ? I may have missed it somewhere.

 

the videos will help you. but as was said earlier youre going to need some specialised tools that are not hard to get. Ive been seeing this stuff on tv called AC pro. I have never used it but you might give that a try. thats if your ac just has a low charge (still has some pressure). if its flat empty youre going to need to find the leak, fix it, evacuate the system, then charge it.

 

Im EPA certified to handle any refrigerant currently on the market. I do remember everything on the exams because I do this for a living every day everything from the reach in cooler you get your soda pop from to the Centrifugal chiller that cools your local skyscraper. I do own the tools necessary for the job. you can bet the ac in my truck runs ice cold because I use the proper methods and procedures necessary to properly diagnose and service said equipment. I'd say I know what I'm talking about. Pulling a Vacuum on a system IS in fact also known as evacuating it. and its not to get dirt or any other particle out of a system, its to remove what are known as noncondensables things that will work to destroy everything you just worked so hard to make work properly. the filter drier is there to capture any moisture that may be present. anything larger than a single drop of water would render that drier useless were talking very small amounts of moisture. you may have confused evacuating with recovering or reclaiming william. and even those are two different things a recovery means to remove refrigerant from an ac system for storage while you make repairs. reclaiming refrigerant involves separating and filtering and basicly more of a recycling type of operation. something a do it your self ac mechanic would never need to do. those machines are expensive. back when the epa first began to regulate all this stuff a recovery machine was quite expensive. these days theyre very cheap.
