Not to bad yourself Nor-Cal Dave! 🤘

[@1776cootsflybynight]

Norcal is my spirit animal 😂

[@nogoa42]

Great video, thanks for taking my suggestion!

[@Studentofhvac]

I remember the first time I ran in to one of these on a package unit. Not gonna lie I tried to remove the core. Kept turning and turning 😂. Thanks for the video.

[@troy4422]

That was a really good demonstration sir, thank you

[@acservicetechchannel]

Thank you for watching my video!

[@makeitcold6649]

Great video as always, personally not a fan of these fittings. I haven’t had an employer willing to put these core removers in the van and it doesn’t make my life easier enough to warrant my own money. They either get a flared tee fitting or cut out and replaced by a slip fitting with a schraeder, if the system is open. I’m already invested in high-flow recovery hoses and schraeder core removers as I was taught this was the way and not to pull vacuum thru the gauges.

[@roderickstarns3004]

I think it would be very important to show the bleeding process as well. I see a lot of people in the field skip that part. We don't want to introduce contaminants into the system.

[@solankibharat8963]

Nice information knowledge

[@hvacslayer2929]

Aaon loves these 🫠

[@davegeorge7094]

Wow never saw one, thanks.

[@devnull7550]

The price of that core removal tool is hilarious. The annual sales must be in the double digits.

[@BetoGarcia-r9o]

This new stim will be installed in all HVAC units?

[@davegeorge7094]

It look industrial/commercial an not on on homes?

[@danielmandel750]

Sucks I can’t use any or my bigger size hoses. I don’t have core depressors in them. I asked carrier and they said just use your gages.

[@sethsturtevant9082]

Get an appion core control tool, it acts as a depressor and gives good control.

[@throttlebottle5906]

you may be able to add core depressors as other option.

[@TuHavilah]

Where have Air conditioner school NY please?

[@juanleon2631]

Excuse. I got question where is the school Florida or same where also

[@acservicetechchannel]

We now only teach online and at expos, thanks!

[@publicmail2]

What your best recommendation on an old R22 valve core seat damaged? Cannot put new valve core without big leak, now using security caps which seem to seal good vs brass caps. thank you

[@ABCJKE]

I ran into something similar about 15 years ago. Trane type unit that someone torqued down the acorn cap so hard it bent in the top of valve seat so Schrader valve would not come out. 1) either leave it the way it is if holding or 2) remove the refrigerant, braze in new stem and seat, pinch off old stem near the top and cut it off and braze it closed. Hope this helps.

[@freonpeon472]

Problem I have is this CoreMax 'hot tap core remover' is much larger than the tool used on traditional schrader cores. Carrier small package units have used these for years now BUT THEY DON'T ANGLE THE ACCESS PORT TO ALLOW using the large 'hot tap tool' in tight compressor sections!!!

[@jasonjohnsonHVAC]

I do not like coremax fittings. If they are leaking. I put a swivel tee on them unless im recovering. Then i will replace it. They do allow for better flow over a Schrader. That tool used to cost like $175 many years ago.....the price of it nowadays is ridiculous.

[@himrfreeze]

Nice

[@brianmcdermott1718]

👍👍👍👍👍👍👍.

[@Shawn_RHVAC]

Don’t forget that these fittings are to be tightened/ torqued to 6 ft. Lbs.

[@garryburrell954]

Were do you get the torque wrench from?

[@Shawn_RHVAC]

@ ordered mine thru Hoffman supply. It’s pre set for 6# but honestly a snug tightness is usually enough. Lot of guys over tighten and they are ridiculously hard to remove with the core tool. I only paid 100$ or so for my core tool. Believe 75 to be exact also thru Hoffman Supply or even Johnstone supply

[@jeffw.4604]

8ft lbs or 96in pounds, not 6lb.

[@throttlebottle5906]

it's more like "with minimal pressure/gas loss".

[@weavercattleco]

That little o-ring seal is going to do a wonder on the coil distributors when it comes off Just another example of more overpriced crap someone is trying to force you into buying

[@allenheineck2359]

Should have eased off slow at first. Closed the valve and then cracked it to make sure. Suspect info here....

[@hvacrefrigeration5204]

That COREMAX CORE REMOVAL COST cost $600. I am not gonna buy it. When it leaks I just use a cap that comes with flare inside, and stop the leak really well sir.

[@IceWhiteice22]

It really don’t make much sense to charge that much for that tool.

[@timothy5977]

All AC tools cost too much!! I mostly buy used/eBay because it's just to f'n expensive, and after it breaks, I can buy another one off eBay, still cheaper than one in the warehouse

[@mackenziegray2090]

I change these things out everytime I need to recover refrigerant. They leak fairly commonly.

[@cesarmoore7996]

$600 can easily be made back in 2 service calls and it will save you time in the long run. However your method works too, even though its just a bandaid kind of fix

[@666miguel99]

If ever you're in a situation where a system is empty. Do everyone a favor and install regular valves, always remove these "max core valves".

[@LawpickingLocksmith]

A schrader on steroids. But another tool to carry for a tech.

[@CSSforever2]

A $600 tool. Coremax should be banned.

[@jackshel]

Don't like them. Several times put gauges on and the pin would not depress, thinking the system has no pressure. That pin has a lot of wiggle in it and the pin fails to depress. Would never purchase the tool. Too expensive.

[@qsm1334]

Damn I was expecting like 150-200 dollars when you said expensive not 500🥲

[@dylb8801]

Mmmm still restrictive

[@ABCJKE]

Agreed. Better but no cookies. Got to get the tool to go fast on vacuum.

[@dylb8801]

@ABCJKE cookies and cream?

[@ЧБчел]

Useless. On VRF you have a few points to recover , use them .

[@AMCHOTC]

There's always someone. New here?

[@nizarokab-p8v]

On an older video of you troubleshooting an ecm motor can you please tell why the speed taps selection went trough a resistor in the wiring diagram? It even has the 24v common as well

[@skutahuniai4830]

Go to THAT video and ask your question. This video is NOT about ECM motors.
