Agreed. Used it multi times. Mixed bag. 50/50 works. Of the 50% that it worked, about 40% of them, it holds 1-2yrs then it needs replacement

I'm in the middle of my change out. Virgin here. Old one was 5/8, new one is 3/4. I'm scared but this has helped a bunch. So basically, roll it out flat as you go, then go little by little. My outdoor unit is close to the hole. I have a bender that i may use sparingly but not full 90 degs. It's a tight space for sure. Cheers or do you say hang loose

A neighbors AC has the white stuff, and it's a few years old maybe 3 or 4. it looks like someone hit it with a blow torch and it's eaten away, vaporized. Now i know why. The line set in it is very corroded. VERY. blue/green chunks. Thanks for the tips. My set has the highly tear able black stuff on it. Spongy/soft and very thick.

Just came across this same type of furnace ealier this year. From what I can tell from the video, it's probably the same model. I tried fixing it because the heater didn't work anymore. Now that I know that its been recalled, I am going to condemn it. Liked the video. 👍

I use it only on old clapped out units if the custy wants it to go maybe “one more summer”. Other than that I dont like it really. Id rather just find the leak and fix it but thats not always possible.

If it’s an old system r22 and customer is on a budget I’ll give it as an option to get them through the summer. And if it doesn’t work like most the time there is a visual for the customer and an easy leak find. Usually line set etc is replaced anyway on change out. But why waste $500-1000 and just get the new system With warranty blah blah. But they already add it to vehicles supposedly and I heard companies are or may start sending hvac units with it already in the system. As some companies with major contacts new homeBuilds are getting empty units and leaking evaps from factory

well said i have used it to for a band aide situation until a replacement couple times mixed feelings on it great review red you summed it up well done! great video

When my Trane system evaporator coil was leaking at 10 years old some sort of sealant / conditioner was added. System is now in its 18th season and still running perfectly. Never added another ounce of 410a. Hope I didn’t just jinx it ! 😱

Haha I visited California from North Carolina a few weeks ago and couldn’t help to notice how different the HVAC systems are in California. Noticed exposed ductwork on top of residential houses lol y’all have a lot of rooftop package units for residential properties. In North Carolina package units for residential properties are always on the ground, we have a lot of Goodman and Trane in my area. We have a lot of cheap builders who make absolute flex duct monsters in the attic

The newer type products do work quite well. And they do not clog or gum up the system. But it will not work on a Crack in the line. It must be a hole. Leaks on the end of the coil where the line go through the end plate or most likely a Crack. So leak stop does not do well there. Leaks in the middle of the coil are most likely a hole. And this does much better there.

I have used it as a last resort, and if the unit is out of warranty. 50% success rate is my experience.

Problem is when you have to return for another sealed system repair on that same unit in the future. Say you have to come back to replace the compressor. Well when you recover the system, you’re not gonna get all that stuff out. And once the system is open to the atmosphere residual sealant in the system will start to harden and you’re gonna have restriction problems. Have seen it happen multiple times. It is a last resort option on an older unit.

It's great for finding the leak.. come back in few days after injection and hit it with a true u.v. light and it will show you if have leak and it's location 🎉 🤙🌴🤙🌴🤙🎊

Complete and utter garbage product

Worked for me with a small pin hole in the evap coil. But lost the compressor 3 months later with an awful bearing noise. Related? Maybe! Also would you want this stuff in your recovery tank when you’re working on other customers units? If a one and done for yourself it’s ok, but for a tech, hmmm.

I use the non-dyed sealant and it worked on 1-1.5 lb/yr leaks. Anything larger, don’t waste your time and customers money. It never gummed up anything.

My thoughts? After using this product, I had some of it leak out of the dispenser onto the service valve and the cardboard box it came in. I let it sit exposed to the air for several minutes, and none of it hardened. Not even a sign of a thin skin layer of hardening on the product.

I have tried it a few times and it did work

The hardest part is knowing the unit / system in question has a bonafide leak, not just a leak due to improper service practices like tight service caps / not plastic caps either. I used some of this years ago and it really did nothing to seal. I can't remember which brand it was. I have a rental house that I own and that unit is from a time period when I used to live there. It's R22 Freon unit that is very efficient even at today's standards one of those 2 compressor style units. The problem with this particular unit is keeping the E-coil from leaking I've replaced the coil 3 times since about 2008 when it was installed new. About 9 months ago I took out the sniffer and verified the indoor coil is yet again leaking. So I installed another leak sealer, not the one you mentioned here though. Then about 3 months ago when I checked the unit I took out the sniffer and could not detect any leak at the indoor coil like I had prevously. The leak in this instance was very small leak. Maybe 3-4 lbs and this unit probably holds around 18-20 lbs of R22. 18 SEER 2 compressor unit. I have another customer I put some in to his system, but no verification if the unit is leaking / the service caps were loose at the time I serviced the equipment. Improper service practices because people are more inclined to shop cheap than do anything right. That said: Refrigerant leaks are real.

I like the dye but I’m not a fan of the kind with the sealant in it. It can gum up the system pretty easily. Especially with a txv. I have used it when a customer asked for it. The dye is awesome though. You can have a recovery tank partially filled with virgin 410 and some dye in it and use part of it to fill a leaking system then just come back later with the UV light or when they call when it’s not cooling. It’s great for those very hard to find leaks.

Its just a money making scam for both the tech/company and the sealant manufacturer IMHO. If it was so great condensing units would come pre-charged with the stuff. The leak sealant industrial complex lol. Im not convinced your unit is not leaking, need check it on a warmer day.

I already know a bunch of people have negative opinions of this stuff. I just wanted to provide an objective resource to help people making an informed decision if they're trying to decide whether to use leak sealant, or not. Let me know what you guys think of this stuff. Garbage or legitimate product?

Looks good, I do like those units have installed about 9 of them and no real issues even with the deep south humidity they work

When I can’t find a leak to save my life and it’s a micro leak. I nitro charge system to 450psi. And literally rinse the coil down with water with water hose. Coat the coil with running water. You will find it. If not it’s in the coil somewhere call it a day get a new one..

You can use a tube that's small enogh to get near your ear and the other end attached to a metal coat hanger and you can hear any leak even if you can not fell it.

We call them slab coils. We have them a lot here.

This new mini split crap are throw aways. Mitsubishi trash, parts expensive and hard to get. Like most 17 seer and above are screwing the consumers in the long run.

Looks good, is the air handler 120v or 240v ?

Great job 👏... Do you like the wireless 🛜 thermostat...have you had any issues

nice job red and the crew a good ole crawler got to love it !

Nice one. In my part of the country we have a bunch of homes from the 1800’s , short ceilings in the basement. Not uncommon for us to see slab evap coils because of this. Usually hooked up to lo boy oil furnaces. I’ve even seen two on the same system installed on opposite plenum branches.

Nice job!

Finally got another install edited for your viewing pleasure

Have you considered installing discharge air deflector to make sure it doesn't cycle the air

Sorry this happened to u, I know the feeling of gettin tools stolen in front of yr home, like u said u feel violated. Keep yr head up ✌️

Subbed

Good practice to just replace schraeders anyway takes 5 mins if you are already nitrogen testing you need to pull vacuum anyway, also I look at evap coil pressure tests, I go near the maximum amount per manufacturer, you will hear the hissing

I started just pressuring the system to 50 lbs at first . I used to ramp it up to 250 and that just killed my nitrogen tanks . Very annoying when a tank runs out and you need run to the supply house for refills .

Just don't touch those fresh metal shavings because they are hot! 😂

Found one today on a 20T unit using my D58 pretty quickly.

A common Issue is The Unit is low on refrigerant. Numerous companies just come out and recharge systems without ever searching for, isolating and repairing The leak. They would rather change Out the entire system then fix the problem. Need more training for HVAC technicians On how to identify and fix leaks.

Your a dork!

I use the leak seal with dye, problem is I came back and I could not find any dye and my heated diode leak detector could not find anything. I had to pump the unit back two lbs and told customer I’ll see them next year. I could had spend more time in the 125 degree attic but I can only do so much😅

Question how did you determine the system had 0 psig without checking the pressures you had to have attached gauges to verify flat system this video was very vague because you kept saying you did not use gauges but the system was flat did you push the schrader valve down to find that it was flat if that is how you found out that it is flat I have seen a system that had a broken schrader tip and the tech said it was flat but it wasn't the schrader was bad and it was because a tech was pushing in on the schrader valve and they bent the stem to check to see if it had pressure so best practice is verify flat system with some kind of pressure test ie...hoses with manifold or probes but always test pressures to verify your suspicions.

very common spot prob was a rubber! 410 a system you can really jack the preasure on those not with that regulator love that regulator but not for leaks great video red get you a H10 best in the biz leak detector leaks will fear you!

I tried to be more clear in this video than I have been in other videos. Let me know if the delivery of this was better than past videos. I think I covered most of the basics as far as finding a leak on these systems but if I missed something feel free to chime in

I’m new to the trade and I have so many questions . But it’s really hard to understand the electrical . Can you simply explain how a hot wire and common wire blow up some of the components?

you sound earnest, but you are projecting your own frustrations.
