I thought the new AC gas not harmful to the ozone?
That’s why the change over! Isn’t it?

Just found Eric’s channel yesterday (go figure) some of the best vids I’ve
seen on YT.

Hi, my mechanic told me that this process would take 1 hour, does it sound
like it will be done properly? Thanks in advance :)

You’d think a company can come up with a DIY refrigerant recovery, evac,
refill machine.

SuperJeremi10 says:

hey what can i do i just put in a new compressor ac system has been open
for 10 years + i have new hoses and condenser coil can i reuse the same
coil thats on the inside cab under the dash i have a 94 c1500 and in order
to replace it i have to remove the dash i have everything to re hook it up
and it be a new ac system just wondering if i need to change it if it dosnt
leak i was going to hook it back up and take it to a shop and have a vacuum
and recharge done with new compressor oil just i dont want to have to
remove the dash.

Another great video. This man is a great Instructor.
Thanks for helping out the poorer people who cannot afford the Dealer
Price’s or another A/C Shop Price’s ! 

MaxxFordham says:

Hmm… there would have only been the “sucks” pun if you had meant that
“sucks” to mean 2 or more things at once, like the idea of drawing the
fluid combined with “this is bad.” What supposed “pun” were you thinking
of?

George Harris says:

Good video. Thanks.

It’s not recommended to turn the can upside down while the compressor is
running. You might draw liquid directly into the compressor damaging the
compressor. This is more likely to occur during the later stages of
charging when the pressure in the compressor is higher.

Turn the can upside down initially without the compressor running to allow
the vacuum to draw in liquid for faster charging. Then turn the can right
side up and start the compressor to draw in vapor only.

I agree with the others about the need to purge the supply hose before
adding refrigerant.

Joseph Scheibmeir says:

When you hook up the refrigerant canister YOU MUST PURGE THE YELLOW HOSE
BEFORE CHARGING! It is done simply by the following: step 1: hook up yellow
hose to refrigerant can. step 2: turn the can upside down and open the
valve on the can so the refrigerant fills the yellow hose. step 3: at the
manifold assembly briefly loosen the yellow hose until you get a small puff
of liquid come out and seal it back. Then you can charge the system.

Orison Squirrell says:

u didnt purge any air out those lines.. letting noncons inside.. humm..

Osman Jubara says:

Charging in suction line must be vapour so that you don’t up side down the
cilinder
You could charging a liquid by using a red hose

I have a problem with my car.Polo 1.4 16v model 2003.There is a red light
or a symble which apears on and of. It apear just above the head lights
symbol.Please help

Dennis Carey says:

I always thought that when adding refrigerant, the can has to be held
upright for gas. It even says that on the can.

smssuper says:

thanks man..

praveen dev says:

u didnt purge any air out those lines bro

HUGO NUNEZ says:

Eric good work

PS Lucas says:

Hi Eric – thank you for these two useful videos on identifying and fixing
leaks with the AC. I won’t be doing any of these things myself, but the
info will help me immensely when I go to speak with an AC garage – recently
had some AC works done and after some initial cold air there is no more.
So, I need to id whether any gas was filled, if so then has it leaked (the
garage that did the ac repairs is not saying whether they gassed the system
thus I’m having to go somewhere else). Thanks again – appreciate.

Scot Cook says:

I am concerned with over charging the system. The pressures look pretty
good on the gauges however there is still foam bubbles in the sight-glass.
Is it better to leave the system a little low appose to risking over
charge? 

Jason Davis says:

in Australia, u cant do this at all… totally illegal…but thanks i
repaired my whole ac myself then ran off to a dealer and got it refilled
for 60 bucks. (normally in aus a total a/c service will cost u $186.00 AUD.

having or selling a/c refill cans is a offense served by imprisonment

safi ullah says:

thanks bro u explain so nicely always be careful may you live long life

praveen dev says:

GAS
CHARGING LINE 

AREA80hEight says:

Forgot to purge the supply hose

chuock says:

you dont purge the suction hose line (yellow line) before charging? Didn’t
you just put non condensibles in there not purging it? 

Mark Bartlett says:

Those thermometers are just like a meat thermometer, or as fellow home
espresso/latte lovers would call, steamed milk thermometer.

omar castellanos says:

Hey Eric I have a question on ac system, , I have a 2010 civic and my issue
is that the get hotter when the car is on park, or while the car is not
moving, put while is driving everything works fine, , wat could the issue
on something like that??? Thanks Eric

Tracy Lee says:

So it’s ok to turn the freon can upside down when charging? Old timers have
always told me that it goes in as a liquid when the can is upside down and
that is bad. I’m not sure just asking, great video!

Bradley Williams says:

The yellow hose is called the service line or service hose.

BigOldCarChannel says:

Brilliant video, both this and part one. Very well done sir, and a big
Thank You.

lucidbarrier says:

Thanks for the video, needed to refresh myself. Make sure to crack that
yellow hose after attaching it to your can tap and opening the tap to allow
refrigerant into the hose. Purging the air out of the yellow hose really
does help with getting that nice vacuum to pull refrigerant into the drier.
Also, I would take the time to keep the can as upright as possible, it
takes longer but you don’t want to damage your compressor. I just shake the
can and tilt the can slightly every few seconds. 

clementsmi69 says:

You should never use the r134a with sealant and always have the ac on high
and the fan on high 

JustHavingFunNow says:

Eric, at the 6min mark you mention making sure you have seals in the hose
before starting. I believe I have the same are near identical Harbor
Freight AC Gauges Mine are US General and the supposed seal are white yours
must be the Pittsburg Tools version but identical every other way. The
parts break down the manual show no replaced seal and when you call Harbor
Freight they know nothing beyond the breakdown you can read in the owner’s
manual. So with that said, the white seals in mine are not a pliable
rubber like you might imagine but instead a harder plastic feel. I went to
Harbor Freight and looked at one on the shelf ( they opened it for me ) and
the Pittsburg named product was the same way only black ( how it looks in
your video ). I look at professional setups like Robinaire and Yellow
Jacket and they both have replaceable o-rings. Robinaire is the donut
style and the Yellow Jacket is a thicker pipe style. That comparison was
no help. I hate to connect these only to loose a charge, can you share
some more details on the seals for these Harbor Freight Tool hoses? I
wasted a day looking on the net and actually going to Harbor Freight.
Thanks for any help you can share or I would welcome thoughts from your
viewers. P.S. this is my first crack at recharging in over 20 years so I’m
re-learning all of this. 

Ian Holmes says:

where can i get one of the can connectors from?? got the manifold guages
but cant find connector for yellow hose to aircon can

1943jbay says:

This man does not understand what vacuum pump does do a AC system. We use
microns and not inch’s. 29 inch’s has 20,000 microns and depending on
ambien temp, we need the system down to 18,000 microns or lower to remove
moisture.

Tedybear315 says:

For the ones yelling about “purging air” from the service hose. He used
the hose to add oil and the U/V additive. The amount of air in that hose,
when compared to the vacuum in the entire system is very tiny. Put another
way–you remove the hose, fill it with the oil/additive. How are you going
to purge the air out of that hose? Hook it to the vacuum pump and you’ll
draw the added fluids into your pump and out the exhaust Granted the
method I was taught was to (while the system was being serviced) introduce
the oil to the part being replaced–or even dump the additive into the
system. Then hook the service line, vacuum the system for 30 minutes or
more..swap hose to the tank and refill. I’ll sit back and wait for the
flaming to start. This is how I was trained and have done so for the last
25+ years. (and I’ve never had an issue)

Gregg Effisimo says:

With out Purging the line before introducing the 134a into the system you
will add air into the system….Air = Moisture, Moisture = acid, Acid =
compressor burn out…..

Ronnie Rhoton says:

Yellow hose is the utility hose..high side pressures should be near 200psi
on a cold day and near 250 psi on and an 80* day.

Justin Gibson says:

If your fan was on high the compressor wouldn’t cycle on and off. This is
how you want to do it when charging. When your fan is on low the evaporator
core is getting so cold that the thermostat is cutting off the compressor.
We were always taught to turn fan on high when charging to prevent unwanted
clutch shutoff..

Mark Bartlett says:

i’ll be like…. ffssssshhhh….. off it goes up into the ozone…. i wont
be here to see the effects…lol. Just kidding.

Ramon Flores says:

I have a 1996 Toyota corolla air cond comes on then it shuts the compressor
off I put a set of Gage’s and when it stars I have good readings but a few
seconds the height side reads low and compress shuts off.
