Scheduled this wednesday for a oil additive call on a trane package, will be bringing a replacement txv incase the oil doesn't do the job. Thanks for uploading this! 2 years green in residential, you have a new subscriber sir

You shouldn't get 600psi and 45 degrees subcooling on any system even with the metering device 100% closed. That indicates such a gross overcharge that the entire liquid line and condenser is full. People think high head pressure=restriction. No, it doesn't. With a normal, clean charge, a restriction will result in *low head pressure and low suction pressure.* Head pressure climbing out of control means the internal volume of the high side is largely noncompressible, ie full of liquid (and/or noncondensables). Anyone who doesn't believe that, ask yourself what happens to head pressure on a recovery machine when you're pumping into a *100% restricted, closed vessel* with no outlet or return... It just condenses and head pressure matches temperature of the recovery cylinder.

I'm sure the previous technician added refrigerant thinking the charge was low. You are correct though.

Did an oil treatment Thursday and had similar results with mine, couldn’t get out of high 20’s with superheat. Plan on follow up this week to see if the valve will ultimately have to be replaced. Bottom line I did get them cooling in the mean time. Love watching you work on them when I’m not. 🤣.

Un load the charge charge nitrogen 350 psi for 1 day and then pull vacume 300 microns and make damn sure it doesn’t move or you have a leak and then add Freon to system and see where you sit I almost guarantee u will be down at 15 with a 9 sub coolin

Good Job Ted!!! ....... Did quite a few oil additive jobs myself. I also found this works when you have a TXV issue in general. A lot of TXV issues not related to the rust inhibitor problem but more related to installation issues brazing without nitrogen also causes the valve to stick. Clogged up the inlet screen on the valve doing the exact same thing when the rust inhibitor does.. I tried to warn my installers but they didnt care. Service department would have to go behind them and fix it.

thanks for uploads man, learning a lot from your videos. I just started out in the trade for service.

You can learn a lot from watching any of the HVAC videos on KZread. They all demonstrate ways to do things but the question is, are they good or bad things? Most of this stuff is fluff and bull. Few channels actually show you how things really work. There are purists that think every service call should include reading duct pressures to others that are just pure hacks, (and I don't use that term loosely), Once running calls on your own, you'll discover the bottom line is learning how to cut the fat out of what you do, Hopefully you'll become capable of simple logical thinking to save yourself time on each call so you can do more calls and make more money while still being able to be reasonable, develop a following and realize it's not about hitting home runs every time but creating long term customers for decades to come. That's what building an honest business or following is about. If I sold every one of my customers a new unit tomorrow, I wouldn't make much over the next 10 years and I'd have to look for fresh meat constantly. Give people options they can deal with. Repair or replace. Eventually you'll get the replacement if you hang on to the customer. Having to constantly find fresh meat drives up advertising costs, etc., where as I spend very little now and have a great following and customer loyalty percentage. A lot of these guys are doom and gloom salesmen who really don't understand how much of this works and only want to install new equipment because they don't have it in them to be able to make a 20 year old unit work like it was new, or pretty close. To some it's wiser to install new equipment than it is to actually understand how the equipment works and be able to problem solve even the oldest units. They think that's too much work for their brains but don't have a problem exerting that brain power on how to rip people off. So take any of this with a grain of sale but learn something from all of them. BTW, I'm not implying anything about this particular video. I didn't bother watching it. I don't agree with additives of any kind such as zerol ice or any of that so don't get your neck up Mr. Anti DIY guy. Just trolling the comments to try and save a few new guys and show them how they can make a good living without having to become whores to the industry and sell their integrity for a few hundred or thousands of dollars.

Great videos. I'm primarily a boiler mechanic up here in the North East. Otherwise, I have tested amp draw on hydronic circulators, and found after oiling the bearings, in many instances the amp draw returns to normal readings.

I like ur videos it’s nice to see a honest man at work I live in n c and I just got ripped off last month my heat pump was marking noise he replaced the fan blade say it goes bad all the time it is a train xl 14

Iv'e had good luck with the treatment. Cleans that wax out of the txv. Once I get the injector connected and the manifold valves closed. I purge the air out of it at the low side fitting at manifold. That injector can hold a lot of air. Nice work and let us know what happens.

A/C Nenew worked good for my Trane system. It was making more noise than it should have, especially in first stage and cooling too well in second stage and not well enough in first stage. After a couple of days of using it my system got much quieter and cooled properly in both stages.

nice find!! I don't do residental but commercial industrial and refrigeration work but heard about the tx problems... I'd like to se a update on it it does interest me...

I keep NuCalgon AcRenew aka Zerol Ice on tap. Works 75% of the time on TXVs and Rev Valves. I always recommend an injection on even Piston Systems because (and I've seen it every time) it lowers amp draw, compressor temp, and lowers head pressure while widening Deltas a bit.

Nice job. You obviously drained some refrigerant bud but you gonna change that txv on Monday no doubt.

Amazing what the oil treatment can do.

great job ted

Would that have the same effect for a heat pump / reversing valve?

The screen on txv is plugged. Or drier blew up inside

Used to work for Lyon Conklin Ferguson. The TXV valve was sticking and getting clogged up was due to a rust inhibitor added to the compressors. That was a nightmare.

If you ever come across a Movincool spot cooler unit, please film it. I'd like to know what you think about them.

What if you recover some of the freon?

This might sound a little 😜 but usually I can unstick a stuck TXV with the additive and also getting the sensing bulb hot and cold as quickly as I can. Torch - ice water over and over. I don’t cook it, just a few licks of the flame from map gas. I’ll also tap on it with the back of screwdriver.

Thanks for the information!

What where the months and years of the rust inhibitor problems? I thought it was 2014 and 2015 Copelands

Nice. What’s the model for the pump

I haven't heard of this oil interesting do you think it was overcharged a tad great video

Great video thank you

Zerol works 50-60% of the time(in my experience)if installed/applied correctly. We took a bunch of warranty valves and installed on test equipment with treatment in oil and about half freed up. When uninstalled you could see the color difference in the interior of txv. Wish I would have recorded some of it on video. PS- this was on beer time not company.

Am I crazy or did you not purge the air out of the injector? Maybe it was pre purged. Just an observation Just watched more where you explained, nevermind

Good work

Dr. Cook administers an IV to an ailing condensing unit, and achieves good results.

Great job

How did you purge that tank

Wow those look exactly the same

I was told 410a will clean oil from txv so additive helps txv it coats it a little

Did you have to change valve?

No, not yet.

The coating in compressor leached out and clogs the valve. Go to Trane, they have a list of model and serial numbers of the effected units. If caught sooner, Trane would of paid for it. This one just looks over charged to me.

So what happened on Monday? The customer have to trim that bush back

Quick question, when you were bypassing the TXV/Lines/Evap by opening both valves on your manifold, didn't you risk slugging the compressor? Not criticizing. Just trying to learn.

@bflugan

It's possible to do that but there was probably enough restriction in all the ball valves and manifold to flash the liquid off enough to prevent that. The heat of the compressor will take care of the rest.

Timothy Salomon I got a question. When the sensing bulb loses its charge does it completely shut and not let any refrigerant through? To the point where the unit doesn’t even run, because the low pressure switch kicks it off a few seconds after it kicks on.

we use Zerol ice

I’ve used that oil additive for awhile and it seems about 1 or 2 years later it starts sticking again, and that stuff isn’t cheap, best thing is replace it with an piston

Those condensers look identical.

So I just had a issue with my Trane unit started acting up last year my dealer tech told me today I need additive in my oil and that valve was needing to be replaced 1000.00 dollar repair job but told me there is a bulliten from Trane telling them some models needed it and my model is on the list it is only 5.5 yrs old and they installed the heating and cooling together in late 2014 why would they not contact me when bulliten ws released to recommend I put in additive and last summer there tech told me my system was low on refrigerant confused sounds like a recall from Trane I should have been notified by dealer I think

That condenser was probably plugged, it can’t breathe

Over charged with freon?

Do to a rust inhibitor additive in the compressors which several different brands did this that rust inhibitor cost a very black tar-like sticky substance to destroy the system's make TXV stick clogged up Pistons compressor is coils this is used to fix that problem which we are still facing today even though this was done years ago if the added does not work you have to replace the TXV know I'm more likely replace the coil faster and easier as long as it's under warranty also you should replace a filter drier every time you open the system especially when it's got that crap in there another thing is it's hard to pull vacuum once you put the additive into the system it takes forever to pull that crap out if you're a new technician suggest a customer to watch the AC renew video on KZread it's usually a seller every time they watch a video the atom can be used for R22 410A does it matter the system is old or new

New utube channel.......fix it with fluid....

Damn utube, 7 commercials in 17 minutes. It's getting to the point where utube isn't worth watching.

It all comes down to in the beginning if there is no moisture or air in the system NO sludge could be built up no rust could form on metal part. The technician or manufacturer sloppy assembly are the cause of most-problems. Just like a technician who says all his expansion valves are defective he’s always coming back and replacing them it’s not the expansion valve that’s defective the technician needs to look in the mirror to find the problem. Just like small system cap to plug up with wax deposits caused by the installation technician who did not thoroughly evacuate and dry the system out and keeps blaming the system for the problem.

In the north here i sell 13 seer with piston coils, pistons never fail.

Replace txv, replace freon filter, vacuum and recharge. Problem solved.

Why would you add an additive to a 5 year old American Standard unit with a txv failing and getting stuck. Just Replace the txv under manufacture warranty, if not they are 100 bucks. Pull charge, reclaim refrigerant, throw in a new filter dryer, pull vac, and weight in new charge. That’s God’s way. By the way might want to let the customer know about that condenser motor and that it’s leaking oil from the bearings, that way if it goes out in a week you at least let them know it’s leaking oil. Don’t try adding fully synthetic to a condenser motor next.
