One thing I do whenever I open an older system (10+) is replace every valve core and cap with new ones and use only brass caps with the o-ring seal FINGER TIGHT. Saves me a "what if" and a headache. Gauges can mask the very leak you're looking for.

[@HVACRSurvival]

Definitely a good practice 👍👍

[@Eddy63]

Good one Slick Rick ... Old People Lives Matter Too ... Your a good person ...

[@HVACRSurvival]

True 👍👍

With single pole contactor I always put a double jumped back to single for longevity.

[@HVACRSurvival]

Because I'm not usually able to pick up my own parts because of our shop location, I'm usually suck with whatever we normally stock.

[@jake2213b]

I would hate to give a older person a high bill. After we lost my father my mom was living on $800 a month. I did not know this until she passed and was trying to get everything with her estate done. Some older people are well off but just how many is like my mother trying to make it for 8 years on just $ 800.

[@HVACRSurvival]

I didn't want to mention it in the video but the person that change the TXV was their son that also used to work in the HVAC field. Luckily I made them aware of every option before making the repair. I'm definitely not one of those dirtbags it takes advantage of older folks.

HVACR Survival = presence of an accumulator!

[@TheGgin]

Nice find and fix. yea, I really like the idea of these split systems. Carrier actually made a Variable Speed Compressor version. Thanks for the video. Only seen it from Carrier documentation, never in person. The "J" and "P" series Carlyle compressors are one of my favorite compressors out there.

[@HVACRSurvival]

Interesting, I did not know that 👍👍

[@gregbowman3598]

Good one Rick

[@HVACRSurvival]

Thanks Greg 👍👍

[@jfrancis98]

They are called triple splits. Can’t believe there is one still running. They were on the way out when I started in 1990!

[@HVACRSurvival]

I hear ya! I worked on one back in 95 for a friend's grandma that had compression type fittings at every connection. It leaked like a Snowden.

[@HughesManHVAC]

Crazy looking unit! Brought all the leak detectors out for that one. Great video!

[@HVACRSurvival]

Yeah, I've been recording a bunch of leak detection videos and this one kind of showed them all off LOL. Thanks for checking it out 👍👍

[@hozerhvac4406]

always solid videos from you. great demo of tools as well

[@HVACRSurvival]

Thank you! I try to make them interesting 👍👍

[@HVACRSurvival]

Yeah it wasn't supposed to turned into a sales promotion but before you knew it....🤣. Each detector has its purpose and its strength along with its weaknesses.

[@jimgill5706]

Good work.

[@HVACRSurvival]

Thanks Jim👍👍

[@danf2588]

Nice work. Used to call those Triple Splits.

[@HVACRSurvival]

Interesting. I wasn't sure what to name it🤣👍👍 thanks 4 watching!

[@davidnull5590]

I really can't believe this "Dupont R-12 Freon R12 Refrigerant 30lb Pounds $1050" this can't be right. I seldom use R-12, I had some tanks sitting in my mom's basement, I remember paying $150 for 30 lbs. and bitching about the price. The last few times I bought off Craigslist and paid $110 for each 30 lb. tank. Oh my!

[@HVACRSurvival]

That was R-22, what the wholesale price and retail price is a bit difference. Every area charges differently but all I can say is we're on the low end of the scale.

Man that look like a fun one making you think. Yep a simple ref leak but a fun setup to work on

[@HVACRSurvival]

Oh that one had me pulling my hair out. I've never seen one leak that bad through the Schrader Cores and that actually be the location🤣

[@donnierobertson3088]

Great job and video like always

What a genius you are !

Your crazy Jack 😁. But thanks 4 watching 👍👍

Thanks bud 👍👍

[@HAGICASA]

great work ...smart guy ....good job

[@HVACRSurvival]

Thanks Knoxville, that's very kind of you, I'm glad you liked it 👍👍

[@jorzer18]

Nice video Rick! R22 is ideal for leak detectors. I just sent out my H10 for service and was looking into getting a backup. Maybe the Stratus or Testo 316-4. Got off topic. I heard of units with compressor in the house just haven't run into that yet, interesting

[@HVACRSurvival]

This particular design originally had the option of special screw together fitting type connection. It was a massive leaker. LOL

[@HVACRSurvival]

The new inficon select was just released today, I would get that over the Stratus if you don't need the ppm display.

[@thejammer3359]

Yep it happens more as the r22 units are ageing out.

[@redeye2629]

You can tell a good tech when you go through the proper procedures to troubleshoot a system and recheck you're work after the fact. I've had some Tech's in my company just charge the unit and leave to only find out I would have to go back behind them show them how to use the tools to find and repair the leak. Still can't beat bubbles for pin pointing

[@HVACRSurvival]

Thanks Chuck, I try to do it right everytime. I'm OCD 😁

[@redeye2629]

HVACR Survival well it works for you man.

[@billcv80]

Have that amprobe ultra sonic, saw the accutrac at AHR show and it seemed really nice.

[@HVACRSurvival]

I've been pretty happy with it, it's not perfect but none of these detectors are. Thanks for the comment 👍👍

[@raykeys360]

Rick is the man!!!!

[@HVACRSurvival]

Thanks Ray, but I'm just a normal guy showing what and how I do my repairs.

[@sknight0391]

The Ultrasonic is superior on those kind of leaks. 👍

[@HVACRSurvival]

It definitely shined 👍👍

[@hvactechpr7872]

Nice find...

[@HVACRSurvival]

These Alex 👍👍

[@throttlebottle5906]

that desing and what they did with the gas type = criminal charge should be brought against all in play...

[@beardowns8050]

Great vid man. Definitely an interesting one. 👍🏽

[@HVACRSurvival]

That crawl space was pretty nice. 😁 Thanks 4 checking it out 👍👍

[@sterlingarcher46]

Them bloody Schrader ports always end up leaking , be it refrigerant or oil . Now , with a 30 year old unit they probably got their money worth though ... Btw , Inficon need to sponsor you , send you a free tool or something for crying out loud !

[@HVACRSurvival]

They sent me the refurbished Stratus 👍👍. But I paid for the rest of them 😁

[@joeshearer1247]

I had no idea this kind of system existed. What is the purpose of a 3 piece system?

[@HVACRSurvival]

I'm not a hundred percent certain, maybe it was serviceability maybe to prolong the life? This thing was built before I got in the field by about five years.

[@HVACRSurvival]

You would think putting the compressor in the house would be the last place you would want it for that?

[@z06rcr]

sjef oekel I’d think a conventional unit with good compressor blanket would be competitive on sound abatement.

[@HVACRSurvival]

Wow, that must be a fancy area.

[@joeshearer1247]

sjef oekel seems like a net gain of zero on the sound levels by moving the compressor inside you now can hear that hum in the basement just as much as outside I would bet. But I guess it’s your own unit and not the neighbors unit you hear so maybe I can understand it that way.

[@Sctronic209]

👍👍👍

[@pepsicolachao4537]

That is a weird installation!

[@HVACRSurvival]

I've only seen two maybe three of these. There hopefully about gone by now.

[@lawnmoose]

What is the going rate for R22? R12? R134A? R410A?

[@HVACRSurvival]

Depends where you live. R22 around here is $45 and up per pound.

[@throttlebottle5906]

contactor, more like remnants of one :))

[@mauricekendallii3658]

Im new to HVAC. Why was the suction pressure high for this system?

[@HVACRSurvival]

There's a thing called a reversing valve inside the unit, it reverses the flow so that your traditional suction line has now become your hot gas discharge from the compressor going to the evaporator.

[@mauricekendallii3658]

@@HVACRSurvival so this was a heat pump?

[@HVACRSurvival]

@@mauricekendallii3658 yes👍👍

[@sampantiliano]

Shouldn’t liquid pressure and discharge pressure be different since there’s a change in temperature?

[@HVACRSurvival]

I haven't noticed a large enough difference myself to worry about it.

[@chrisgreen8897]

I know the H10 leak detector but what are the other 2 leak detectors were you using in this video??

[@HVACRSurvival]

Inficon Status and Select.

[@jimdamiani1823]

What is the going rate for r22 in your area(on average) thx

[@Bluecollarrebel]

✅

[@HVACRSurvival]

Thanks 4 viewing 👍👍

[@throttlebottle5906]

old schraders leaking after being gauged touched 30 years later? who'd have ever guessed... (show me where they touched you, oh they touched your no-no spots!!)... not meant to be funny but truth-full and the techs need to learn/be punished.
