I used this product 3 years ago on a system that needed 2 lbs of refrigerant per year and it worked. This season the compressor started becoming very noisy… added NuCalgon A/C Renew and it quickly quieted down.
Replacing the filter drier in a year or two will give you back its life expectancy Lots and lots of contaminants from that constant filling without sealing
I put leak sealer in my old R22 system. I'd have to add twice a summer, but in heat pump mode, it was 2 days. Afterwards it ran for another 3 years before the compressor died and never added anymore R22.
I have been dealing with a leak for the past month in the coil during this texas heat and my AC guy is going to try this despite his skepticism. This video gives me much hope, thanks for sharing man. I could use the break from expenses lol
Did you check for acid while you were there? If there was moisture that was already hanging out in the line set before you got there and it already became acidic, then the drying agents won't be helpful meanwhile the heat will also accelerate the instability of the refrigerant to form more acid.
Thanks for the vid and walk through. Did you inject with the compressor off? Didn't sound like it was on. Can't find anything in the instructions saying if system should be running or not.
Caron dioxide is a non-condensable gas and should not be used to inject the leak repair fluid. Recommend weigh-in refrigerant since system is undercharged anyway.
That's a refrigerator based cartridge the company stated that you should only use their cartridges or you will be shooting air into the system which is terrible
that stuff works, but the condition of that A coil is so bad, it's on borrowed time. Eventually it will spring a big leak and no seal be able to handle it. A band aid for sure.
I have this exact ac unit its 2.5 ton and a tech said i have a leak and will need 4-5 lbs of freon. How much would you typically charge to fix a leak and add freon? Also how long does the product fix the leak for?
Yes, but most of the time, these don't work, but you might get lucky. I've injected a ton of these things for my customers, and very few made any difference. I think it's mostly a scam from the product manufacturers.
Honestly if its the joint at the bottom of outdoor unit where the copper meets aluminum I wouldn't try it. Thats a tricky spot. I've heard of guys using the Solderweld copper to aluminum rods or those new sharkbite fittings.
@@TerryRGrahamDefinitely not whst the consensus is. Most ppl notice improvement for small leaks. Similar tech as sealer for radiators which I've used myself.
You were burying your tip into the pan that can cause a false hit and also leak testing the same spot won't work you will still have diflouromethane in the oil residue.
@@WorldofHVAC Link worked fine for me, ordered it and Ill see if it works on my unit. I am having to add about 2 lbs of freon every month but cant find the leak! Its an old unit and would like to just make it last the rest of this season.
@WorldofHVAC well... the unit froze up when I wasn't home maybe 2 days after putting the stop leak in, and then the compressor burnt up the next day lol.
Dependant on the size of the leaks and where you live If theyre pinholes and you run heat pump prodominately you may make it There are some that can handle 100°+ which will seal it
You pressed the trigger three times, yet you told us to press it one. Is there a chance you could inject air not CO2 that was not purged from the sealant tube?
The video they had on their website shows one shot. But I wanted to go slow because I didn't know how fast the gun was going to push the chemical in. I didnt want to push C02 into the system by holding down the trigger too long. I couldn't reshoot that demonstration, I said one shot but played it safe.
Most hvac techs won't use this anymore, in fact our company has directed us to stop using it all together. If you have a txv metering device, leak sealers will ruin them. Best case you stop the leak for a year or two and then will be paying more for a new system in the coming years with inflation and price increases. Best to fix it or replace the system immediately at current market prices.
Used that exact same product and variant on my 25 year old leaking r-22 system a couple years ago and it is still leak free.

Did you get this done yet? Curious to see if it worked out for you
@@jamesbroomfield7799 we did get it done, so far so good. AC has been cooling well. He will be coming back to test for leaks in the coming weeks. 👍🏽
Just ordered a full kit to see if it will solve my slow leak issue in my mobile home. Fingers crossed that it works!
I like your troubleshooting card taped to your gauge set. Great Idea!
Thanks! It has information on both sides but the compressor scenarios are clutch
@WorldofHVAC do you have a website or ig that you can post that troubleshoot card on?
Are you mixing C02 and 410?
Worked for me on my '06 R410 system, no doubt

does this product work just as well on refrigerators and chest freezers?
Thanks for the vid and walk through. Did you inject with the compressor off? Didn't sound like it was on. Can't find anything in the instructions saying if system should be running or not.
Yes it should be running. I just isolated my voice over the noise
This product can work on car evaporators?Honda hrv 2021

"a non-condensable gas"
Lol.

Science!
Nu-Calgon Ultimate Easy Seal is the best product.
Great video! Question: Should the ac unit be off when you inject the sealant? Thanks.
No I would treat it like refrigerant. Send it with the flow instead of pushing it into standing pressure
@@WorldofHVACThanks!
On if you use gauge or tank off or on if you use a gun
Duz this work????

Can this work on car 134a systems?
Yes, you'll need the small system leak seal from nu calgon. They size them all for different size systems
Co2?

What the name of that leek seal
The Amazon link is in the description

Every month! Man that's a bad situation. Hope it all works out. I'd like to hear what the result is
@WorldofHVAC well... the unit froze up when I wasn't home maybe 2 days after putting the stop leak in, and then the compressor burnt up the next day lol.
@@JohnnyAnderson1so did the stop leak ruined the compressor?
I have multiple leaks around the condenser coil leaking oil
Will this work for it
Dependant on the size of the leaks and where you live
If theyre pinholes and you run heat pump prodominately you may make it

Rust means nothing what a joke!

Did you just save me $24,000?
I have prices that high but hopefully you are talking about high end equipment and ductwork
@@WorldofHVAC - I am but it is still ridiculous IMO.
