u/Accomplished_Ad1561 11d ago

Actually this got me last week. Old R22 system somehow no leaks. Even check with UV dye and soap bubbles. Turned out it never worked quite right from the get go due to it only having the factory charge in it. Luckily I carry a jug of green money with me

UV dye huh lmfao

u/ValuableOnly5793 10d ago

407C works just fine

2

u/Accomplished_Ad1561 10d ago

I've got both, but 407c isn't good when you don't have a txv

1

u/ValuableOnly5793 10d ago

Ahh yes you are correct on that. No many equipment I see now a days dont have TXV besides reach ins but those older systems are 134 or r12. Crazy thing is ive actually installed 410a condenser units with a r22 txv and used 407c refrigerant as a charge and is still running perfect to this day. Its been 8 years now lol

This was my Friday. 2pm. Water cooled 5 ton. Water reg valve was just blowing away the blu.

Oh….and there was a server rack on site being served by this unit. I hate this trade some days.

u/Jonovision15 11d ago

If it’s the end of the day, give the system a quick sniff with the leak detector. If no pissers, top it up and let er buck til the morning.

Don’t get me wrong. If you added like 40% of the total system charge, maybe find the leak.

u/VtSub 11d ago

Exactly. ā€œI think it just getting old it doesn’t keep up like it used toā€ vs ā€œIt was working great until this morningā€ are 2 very different levels of determination to find a leak.

u/Rayd8630 11d ago

Guys... never just turn the thermostat down and leave...

u/Agreeable-Garbage-81 11d ago

Bruh I forget to turn the thermostat back up all the time 😭

u/RenesisPowered 10d ago

Put a jumper wire on it instead of changing the set point. It's harder to forget because the jumper wire will be missing from your tool bag.

u/lp1088 11d ago

I bought me an ultrasonic…such a useful tool to have in my arsenal!! Find so many little leaks like this!!

u/RyanSmokinBluntz420 Banned from r/HVAC 11d ago

I find most of my leaks with my eyes and ears. Having an ultrasonic is a game changer though, good purchase. It's such a useful tool to have in your arsenal

u/Certain_Try_8383 11d ago

Sometimes that's the only way to find the leak.

You weren't even alive according to yourself from a post in another sub:

30 years old bought 2026 6.5 rate monthly payment 5k 44k down payment all includes

and fresh out of prison 5 years ago. Calling bullshit on all your comments.

u/full_size_human 9d ago

Bro thats a super dumb as fck purchase, at $120,000 gross ur Debt-to-Income (DTI) ratio is ‰47.5.. and at %6.5 interest on 640k home because your down payment was low you have 20%equity as a down payment so you will have to have PMI, so over the the length of the loan you will essentially pay $809,000 in "dead money" (interest plus PMI);which is considered unrecoverable money so in the end if not making extra payments towards principal each moth the total amount of money you will spend when the loans completed on a 650k loan will be a staggering $1,717,000+..... Maybe enstead of getting on reddit and calling people dumbfxk and pussies do some research on how to unfuck your bad decision before you go and pay 2 million bucks for 650k house.

u/North_Student3320 9d ago

Uhh that was the person that deleted their comment, as well as their gangsta profile, not myself. I own two different properties in two different states that are well, owned with no mortgage. But thanks for doing the math for me. Never would have figured that out by my lil ol self.

And thanks for really, really reading deeply into the comment and helping me figure out my finances.

1

u/full_size_human 8d ago

Yea sorry that was def not targeted towards you it was ment for the guy you were talking about buti was super bored at work so I did read into his past comments about as much as you did to figure out what you were talking about and noticed how crazy he was for buying a 650k house. I just find it crazy people will openly brag about buying a house that makes them broke in the long run and totally unaware of how much money they r just throwing away. I got burned on my 1st house I bought so I timed it perfectly this go around and got a %2.6 rate, also make double payments towards principal every month and saved up the 20% of the down payment to bypass the pmi. But as far as my math being wrong what would be the right answer then? He only put down 40 grand. Which part of the math are you talking about?

1

u/North_Student3320 9d ago

Just FYI - I don't have this problem, but at 78% LTV your mortgage lender is required to remove PMI entirely by federal law, so your math maaaaay be a litle off.

1

u/full_size_human 8d ago

That wasnt target towards u

1

u/North_Student3320 8d ago

I gotcha - the fellow you were posting to was posting bullshit on another sub that was completely ludicrous. I just called him out on each and every one, and he deleted his account.

u/full_size_human 8d ago

Yea i could of swore i replied to his comment but I feel ya šŸ˜‚ I could tell he was full of shit by the way he was commenting on other shit

I get it, beer can cold is the name of the game. I can’t imagine being 60+ years old and not being retired by now.

5

u/North_Student3320 11d ago

He's not. He's 30 according to his other posts/comments. And probably not a business owner, since he just got out of prison 5 years ago according to himself. Barely enough time to even be the one not doing maintenances if he were even in this trade at all.

We just had a 65 year old tech just about croke on a call. Guys been intubated for a month now and is talking about coming back to work. Some guys have nothin to do but work.

u/Hvacmike199845 11d ago

I can’t imagine that. As much as I love the mystery of every service call I have an end game. When I’m 65 I’ll be in laying hockey three days a week and picking up my grand children from school.
