AC Service Tech LLC just out of curiosity why does your low side service Line thicker than your highside. I always thought the high pressure is the thicker line and the low pressure the thinner line.

[@JohnDoe-gk4kn]

Who do I talk to before I beat my repair mans as? He came and told me I need a new system because it's old and leaking from the coils. He charged me $875 for six pounds of gas and services. Well 3 weeks later it stopped working so I did a leak check my self and found this exact valve core leak and its leaking bad. He did nothing but replaced the free on then tried selling me a new split system unit. If I see him in label to catch a charge. I hate crooks

[@WallaceLee-rm4vb]

This man is doing a great service. I had two AC service people tell me I needed a new AC system because I had a "likely" leak in the evaporator. After watching videos and getting some supplies, I discovered there was no leak in the indoor coil. The only leak I could find was in the Schrader valve which I was able to replace thanks to this video. One summer later I have not lost my charge.

[@ScreenPrintR]

Thank you very much. I noticed the AC guy that did our work last time first, charged me $300 to refill. He's the one that loosen the caps, measured the temps, and refilled. He never tested with a type of soap. Any ways, thank you again.

[@hvactech5829]

If you dont want to get burn ! Go to this master teacher. Trust me, I have been following him for years.

[@wbotic]

I did not even know about the existence of such a tool... and I was planning to empty the system, vacuum it and recharge it. Awesome!

[@acservicetechchannel]

I use the appion valve core removal tool a lot. I have the tools I use listed at amazon.com/shop/acservicetech thanks!

[@CACar_Nation]

Can I use this for a r22?

[@GaryOutdoorsLiving]

Thank you soo much. Just picked up this tool for our AC unit valve. Ac guy wanted to charge us 65$ to change a valve out went and bought this 38$ tool which came with 5 valves. Thanks so much for your video and very clear instructions.

[@acservicetechchannel]

Thanks Gary!

[@paulsosa1872]

Gary D where did you find that $38 Schrader valve tool?

[@PiousParable]

You're an amazing teacher

[@acservicetechchannel]

I am glad you are enjoying the videos Lamont Mapp!

[@georgiabigfoot]

The folks who don't like this video are the ones who would rather you pay for a new $8,000 unit instead of replace a $2 core

[@acservicetechchannel]

Thanks Georgiabigfoot!

[@AshishGupta-qo4vd]

your videos are excellent you take ur time and explain what ur doing and the exact profeasional procedures

[@acservicetechchannel]

Thanks Ashish Gupta!

[@curiosity2314]

Very cool no pun intended! One of those magical tools.

[@acservicetechchannel]

Yup, very nice!

[@johncote2776]

Pretty slick! Thanks for showing this. Great tool and video!

[@acservicetechchannel]

Thanks Blue Collar!

[@jennabobenna3631]

Broooooooo! Mind blown! 🤯

[@electricamir248]

Brilliant tool

[@coffeeder]

THANks, it worked, i did what you say here, the asshoe intention bent the old schrader valve in order have more money from me!

[@ba177ba18]

Thanks for making this video. This is what I need

[@acservicetechchannel]

Glad to help! I have a newer video using the appion valve core removal tool where I leak check at the back of the valve core removal tool before taking the tool off the port, thanks!

[@devonpeeples2188]

I’ve been looking all over for a tool like this. I’d like to find one that can connect to the low and high (with an adapter) service ports for auto.

[@jimmyung3212]

Thank you for showing!!!

[@acservicetechchannel]

Thanks Jimmy!

[@jjustice7429]

Just had my unit freeze up yesterday. AC tech found that it was low on Freon. He only had to add a about a pound. Should he have changed the schrader valve also? I know about 2 or 3 years ago it had the same problem and a different company added some Freon to it then. I wonder if it could be slow leak in schrader valve. Thanks for any help.

[@wLkByFAITH.]

That was awsome!!

[@kanive1566]

Can you do the same thing to the King valve if it's leaking?

[@MaMa-qh4dy]

In later videos, you use the appion tool. Which do you like better and why? Thank you.

[@acservicetechchannel]

I have pretty much switched to using appions because I can use them for vacuums too. I used cps for years to replace valve cores but appions work well for vacuuming. Here are some links to what I use, thanks! 1/4" Appion Valve Core Removal Tool - amzn.to/2uYr8WL 5/16" Appion Valve Core Removal Tool - amzn.to/2JHmfbP

[@Kickbasser]

I learned a lot from your videos! Great stuff

[@acservicetechchannel]

Thanks George!

[@robertberin4872]

I used a defectove adapter for my mini split during the vacuum process which wasn't vacuuming the lines because the Schrader valve wasn't being depressed and then I stupidly released the refrigerant into the system. If i recover the reidgerant and vacuum them will that work, or should i remove the refrigerant and add more.

[@JL-ss3ux]

Excellent!

[@jimdavidson5208]

Lube the new schrader prior to installing. Test for leaks. Blow out with nitro or compressed air. Fill schrader with lube again. Install cap.

[@l.crossjr]

Great vodeo for starters. I have a couple of doubts. What provides the seal? Is it the shraded valve core or the cap? Also, many new units come with plastic caps, is it worthed to replace them with brass caps?

[@L8NiteCoffeeSips]

The valve cores that I have on my system seem to have a slightly longer stem, unable to reach or click with the valve core once it’s been threaded on… any ideas?

[@BubCityHoodRides]

Could a bad Schrader valve give gauges incorrect reading? My gauges are getting a 200psi reading on an mo99 system.

[@jimnrel]

Never knew there was a such tool.. always had to recover 1st.

[@acservicetechchannel]

Yeah, the appion valve core removal tools are the ones I use for vacuums since they are rated for deep vacuums, thanks!

[@La2venida]

How far should the schrader be screw on, sometimes if I screw it all the way ..and put my gouges it does not read

[@ferminrosa9620]

Thanks very useful

[@gregflorko8402]

How do you find out what Shrader valve you need for your specific AC unit?

[@noahmcfadden1658]

What size schrader valve core is it that is being replaced in this video?

[@28_babyshark]

How do you know what size straight your valve do you need? I have a York model YCJF42S41S1A (R-410A) 3.5 ton

[@ejc491]

My Schrader Valve is leaking so much that I am wondering if it is damaged. I could feel when I thought the tool was in the correct position over the Schrader valve. I turned and turned and turned, but could never retrieve the bad Schrader valve.

[@robertrlkatz6890]

It is a possibility that the retriever is not the right size or the slot is not wide enough they can be tweaked a little wider if careful.

[@fabiodarocha2842]

How about front seating the valve all the way, and then remove the schrader valve without any pressure at the port. Is that possible?

[@ronhaefner7833]

Nice video. Is there a torque spec for the Schrader? On TPMS Schrader valves it is 4 in lb, granted there would be prevailing torque (possible) on the install tool seal. Are the valves nickel plated?

[@michaelcostello6991]

Does much liquid escape in this procedure. It is the liquid line and refrigerant is in liquid form ?

[@acservicetechchannel]

Yes but refrigerant will certainly leak if the schrader valve will not seal, therefore changeout is needed. When a system is off, both ports will have sat state refrigerant, thanks

[@MrINSOMNIA28]

What kind of air compressor do you have?

[@armandom.5299]

i noticed you were holding the knob verrry strady as you were placing the shrader valve back in, does it spin out of control? Also you opened the valve without completely inserting the valve core, wouldnt the refrigerant leak out and pass the replacement valve? Thanks for posting!

[@acservicetechchannel]

I may have been purging the very small amount of air air. You have to push in as you turn, otherwise it will push the knob back out if the schrader valve is not starting to catch on the threads, thanks!

[@dm4789]

Can soapy water be used instead of the commercial solution that you used? If so, are there any problems using a solution that one should consider?

[@acservicetechchannel]

We use anti corrosive bubble leak detector only. The new dish detergents have corrosives. You would be surprised to see what happens over time with even stainless steel. It is not like it was 20 years ago with those soapy bubbles, thanks

[@ask43242flight]

is the shredder valve same as the one used in bike?

[@NMranchhand]

Man, oh man, that's a clever tool! I just followed you over here from that test video where you showed cutting downspout with the 3-pack of cutters. I can't believe you set all this up in little more than a year. Where should I start on your sight? Come to that, since I'm going to learn with you while I attack the house (1977) I just bought, where do you suggest I start there? Oh, and my downspouts are in good shape thanks to you!

[@acservicetechchannel]

Well here is a list of all the playlists and maybe start with basics- All of the ACSERVICETECH Playlists- kzbin.info/door/OZR-1IqsAer9wzlvFgb4mAplaylists?view_as=public - Well thank you very much! I think I wanted to start documenting it before I forget all of it, ha ha! I am in the process of writing a book for air conditioning basics- troubleshooting in order to put things in order. Unfortunately these videos are piece meal. In reference to order, brazing, pressure testing, vacuum pumping, weighing in refrigerant, adjusting the refrigerant charge, troubleshooting. I don't have too many videos out on ductwork yet, thanks! Glad to hear your gutters are looking great!

[@carefulconsumer8682]

Is that brass cap a 1/4" or 7/16" Thank you.

[@28_babyshark]

Will this tool work on the other side also?

[@lancetan6403]

I open out the service port cap today after 2+ years and there is a short burst of gas. Is this considered a leak that requires valve replacement or it's normal for not touching the service port for long time?

[@acservicetechchannel]

That would be a small leak. You can use bubble leak detector like the small can of rectorseal and dabber I have linked at amazon.com/shop/acservicetech - and check for bubbles forming. Don't use dish detergent and water as dish detergents are corrosive now a days. You could also replace the valve core/schrader valve with a valve core removal tool. I have another video showing the use of the appion valve core removal tool. Maybe check that out as well, thanks- kzbin.info/www/bejne/rJ7XnZmZetdjn9U

[@jheckmann]

@@acservicetechchannel So, a mild soap like Dr Bronner's would be ok to use?

[@pack5eastnorthport366]

Love listening-watching you at work- A - Did you ever have an issue with threading the new Schraeder valve? (Bad replacement, defective, or cross-threading) B - Do you recommend replacing the regular brass valve caps with the rubber inserts? C - Do you use a mirror to see bubbles on units like Ruud with the valves facing inward?

[@dwighta8655]

Would you use this tool to pull a vacuum on a new mini system? Do you have any videos showing how to pull a vacuum using this tool? Thank you.

[@acservicetechchannel]

Yes you can, I don't have any videos yet but am planning on doing some soon, thanks

[@neocatharry2693]

Do they rent this tool at local ac supply stores?

[@acservicetechchannel]

It is not likely. You certainly could check. Here is the link if you needed to purchase, or you could get it at the local supply house, thanks- Here is a link to the C&D core removal tool amzn.to/2bFpobQ

[@tmst2199]

Is there a tool that works for R22 and 410 as well as automotive 134a service ports?

[@acservicetechchannel]

The c & D or the appion work well for r-410A and R-22 such as those linked at amazon.com/shop/acservicetech but R134A have a connection that is different, thanks!

[@Gary-ts6dh]

3:59 - I see your tool is moving quite a bit up and down as you were screwing in the new valve. Have you ever cross threaded with this tool?

[@acservicetechchannel]

No not once, thanks!

[@Drellishakmatt]

How many Schrader valves are there?

[@Ljp7d]

can a leaky valve cause refrigerant leaks?

[@robertrlkatz6890]

if it is leaking it is refrigerant and possibly a little Pump oil

[@jodell2023]

Can this work on a low side of an auto ac?

[@pack5eastnorthport366]

This tool is 5/16” for ductless. Check your size. Might be 1/4”

[@guaporubio]

Can this be used in an automotive AC application?

[@robertrlkatz6890]

Treading and size are different, two different expertise one automotive and the other is residential HVAC. Two different platforms with the same end results and operation, if you understand one you can easily understand the other but the sizes are proprietary. I ask why could they not have been made the same my answer. Patents my friend, Patents!

[@pack5eastnorthport366]

This tool is 5/16” for ductless units. In more recent videos he uses the Vacuum rated. APPIOM tool MGAVCT (iicr)

[@RandomYoutuber1023]

You want to use your thumb and reverse the valve core removal tool slowly and continue to turn the service tool counter clockwise as you slowly move it back. That will guarantee the valve core comes out with the tool and doesn't get stuck inside the shaft. Also, before unscrewing the C&D tool from the service valve, you want to remove the rear tool portion first so that you don't end up with a leak. If there is a leak you can quickly shut the ball valve and prevent refrigerant loss. I am not a HVAC technician, but a homeowner and this is how I replaced all 4 of my Schrader valves on both my units.

[@stevenflores1355]

How would I braze with nitrogen if im replacing the suction line valve?

[@acservicetechchannel]

You won't really be able to except for maybe flowing it through the other side and out through the 1/4 port on the new valve that you were installing. this will purge some but not all of the oxygen out of the lines as the compressor won't allow pressure through. We do what we can, when we can to do the best job possible. Great Question Steven!

[@Mike_not23]

was just quoted $300 to replace schrader valve.

[@w5cdt]

Why not use an electronic leak detector?

[@jakesmith2984]

Can refrigerant be released like the air on a tire? Edit But thats where I recover it correct? I am going to buy the proper tools to evacuate it .

[@acservicetechchannel]

No it cannot because they destroy the ozone and are greenhouse gasses that warm the planet. We must be EPA 608 certified to handle refrigerants, thanks

[@jakesmith2984]

AC Service Tech LLC Ok thanks.

[@musabshalabi6706]

Coooool

[@DANIAC262]

Right meow

[@justanotheryoutuber5228]

I’m not understanding why one would buy this tool when you can pump down the system then closed the service ports to change the Schrader core

[@benjaminbills1998]

Because simply releasing the charge at 0psig would result in much higher boiling point and contamination. You would be skipping a critical vacuum step where you pull the lines back into a state of vacuum below 500 micron.
