I used 3 different AC companies. One replaced my evaporator, and condenser. 6 months later it leaked and I had to replace the line set. They pressure tested with Nitrogen, and evacuated the system and recharged the system. My AC still didn't cool well, so I called another AC company. They added more R410A and it works much better but not great. I never once saw any of the 3 AC technicians purge the hoses. Could contaminated refrigerant cause poor performance? How can this be corrected?

It's possible. The first company should have found the leaking lineset during a pressure test before pulling a vacuum. They also would not have reached the right vacuum with a leaking lineset.

Does yellow charging hose need a Schrader valve? Thanks for ur hard work teaching us need techs

Correction I meant does yellow charging hose need core depressors inside them ?

Great question. Usually No. I many times would pull mine out for faster flow. But it does still need the ball valve

If I only ever work with one r410a system, can I leave the 130 PSI vapor pressure in the gauge hoses?

Could you similarly start off by connecting the low side, opening the low side on the manifold and using the manual low-loss on the charging hose to purge both the low and charging hoses simultaneously? Your method uses pressure from the unit for both those hoses anyway, so it seems like loss doing it this other way would be pretty much identical.

Yes but you left out purging of the high side hose.

Could you the jug (right side up) to purge the lines instead of the LO side service line? Would that be an advantage?

There are many way to pruge. As long as the air is out of all the lines your good.

@@love2hvac Thanks for the tip! Using vapor to purge hoses, conserves R410A (@ $20/lb.). I plan to experiment with your purge method using C&D Valve CD2070 Core Depressor (with a back seat). This may be to fancy, but I think it might really be a very controlled setup.

Q: at around the 9:30 mark you are "bleeding" any liquid refr. trapped inside the red hose back into the low side. As it travels thru the manifold and into the vapor line, because the yellow and blue hoses are equalized, can any liquid refrigerant enter the yellow hose which was already previously bled? Or will it all be vaporized at this point already?

Great question. Yes it is possible for some liquid refregerant to flow into the yellow line. It will be very quick for the pressure to equalize to the suction side and any remaining refregerant will typically, quickly boil off into a vapor. Being bleg is really referring to making sure there are no contaminants. In this case the line was bled att he begining when we first attached the tank. For example. Let's say I did not bleed the yellow hose. Air, or even refrigerant from the last call could be in there. Now imagine I was to open the high side and low side on the manifold. The high side would mix with what ever was in the yellow hose and push into the system via the low side.

In this scenario is the system running from start to finish or are we starting the system when we're ready to start charging?

a liquid charging adapter could be used as well to ensure no liquid goes in.

That's true, covered that in 116. It's important to understand how they work. It's just a fixed hole, a metering device. Left open for too long can still allow a stream of liquid to the compressor. Nice to have but not a solve all solution.
