Comparing Gas/ Refrigerant Micro Leak Solutions on Micro Leak

Looking for leaks an HVAC tech can spend hours on. Sometimes even with the most expensive electronic testers may not find the leak. We also have many bubble solutions to choose from to find the leaks. They are not all equal and some are better than others. Here I am checking a few leak bubble solutions out. They all worked on bubbling up on this leak. I even show how a cleaning product Windex performs on this refrigerant leak. I use Big Blue, Cal-Blue, Diversitec Pro Bubble, and Windex. You can decide which is the best one in​ this video.

I like the way Windex foamed up. Thanks for showing, great video.

[@thehvachacker]

I figured I needed to let others no just in case they were in a jam and had no solution on them every homeowner has some Windex. too bad I put a poll on this video today. I want to see before the video and afterthoughts​.

[@oguzoguz4686]

Windex waaaay better than the others. Makes it very ez to see.

[@scottk0623]

I found that putting 25% of “ kids mr. bubble” in any of the blue leak detector liquid will make big bubbles to aid in location of tiny tiny leaks.

[@mattbentley8958]

Is windex non corrosive?

[@Dyllanes_Ingeniero]

Excelent 👍👍👍👍

[@oldtimehomestead1554]

I think windex won.

[@thehvachacker]

It does foam up nice and quickly. They all bubbled

[@rogrog8974]

Windex

[@ianpalmer1482]

I buy dollar store bottles of childrens bubbles.

[@thehvachacker]

I should try that out should work

[@ianpalmer1482]

I just refill both my sprayer and my dauber bottle. Great videos btw.

[@thehvachacker]

Thanks I enjoy making these videos.

[@jeffcoolhd]

Hacker I'm going with Windex it's cheaper. Peace brother I'm out

[@anthonysgarage]

Cool video. I actually prefer the way Windex foams up. I think that would make smaller leaks easier to find.

[@bobsmith1743]

the camera isn't shaking around enough

[@hozerhvac4406]

Good video. Windex was an interesting find. Thank you for sharing

[@thehvachacker]

It was found in a desperate moment and figured should let others know just in case there Leak solution bottle breaks open in the back of there truck. The other bubble solutions are good and at some times may be better but......

[@jericosha2842]

I just ran out of leak bubbles. Windex is what I'm using today lol

[@carlmccoy662]

Good test, sometimes out of frustration I will try 2-3 different leak solutions, now I can try 3-4. I am going to try dawn too.

[@AnnLippert1]

im gonna use Windex!!! i don't want to spend money as I'll never use that leak stuff again. Also you cant mess up the ratio (making your own soapy water mix) Windex FOR THE WIN. ha

[@DeadlyVoltsHD]

I'd say the winner was the cheapest, Windex lol

[@thehvachacker]

It did react the fastest

[@anotherOneMore7]

Does big blue clean windows too?

[@bennettdavid904]

Oh shit, thank you for the Windex advice

[@TheRobdog250]

So its basically pick your favorite libations .. good tip i used Windex and other cleaners to find leaks i think it was 409 that worked good also

[@thehvachacker]

They all work I was leaving it up to whoever watched at the beginning to put what they though would work best and after what they thought. Windex I discovered in a pinch but I find it helps find some tiny micro leaks

[@WilliamVG]

Alright, Windex it is, dirt cheap unlike Cal-Blue.

[@thehvachacker]

It dries to quick at times

[@derrickenbuenosaires]

I've been using windex since I've seen this video. Life changing video !

[@btomas225]

That's far from a "micro-leak". If you see the hole then they should all work. A micro-leak is one that takes hours to show a slight decrease in pressure on the order of 10~20 lbs.

[@edjovi3677]

bill my best friend works for scg gas co thay use joy lol I buy big blue but window cleaner now!!! lol look the best too me eddie leak master plumbing in ct

[@thehvachacker]

I will still use big blue yet windex does react nicely to a leak.

[@Eddy63]

Windex is the winner IMHO ... Did I win anything ? Lol ...n Good vid ...

[@thehvachacker]

I did almost start this video off as if I was going to do a which is better. Yet they all work but the windex reacted faster. I might get some heat from other HVAC channels for not saying big blue is the greatest. 😂 yet I let the solutions do there thing so others can decide.

[@oguzoguz4686]

Rhank man. Used windex and found the leak and fixed it. My ac works better. Just gotta take the moist out and recharge it.

[@calebburns4346]

Well now I wanna know what was wrong with your neighbors tree you cut it off

[@thehvachacker]

Yea I cut the camera off when he kept talking. I put a frame for a table the wind tossed on my deck over in my yard and a tree grew threw it. I have to sawzall the table apart since the tree is growing through its frame

[@DeadlyVoltsHD]

Also maybe check into automotive leak detectors should be much cheaper say for tire repair? We had similar products at my co op shop

[@thehvachacker]

will look into it. thanks

[@theoldbigmoose]

Haha I've used windex on tires my entire life! To find the leak, then to verify the plugs. Cheap, easy and available.

[@rossflores4382]

Wow thanks for sharing this information greatly appreciated

[@thehvachacker]

That’s what this is all about helping each other out. What good is my experience and knowledge if it can’t help others. The same for others that like to share useful tips

[@Sctronic209]

Windex is easy to see

[@kaizillaboy]

Man. I even use Windex on my hemorrhoids.

[@brianporter447]

All those can freeze in low temp. I use big blue deep freeze.

[@arkansassteve]

Good stuff! Thanks for sharing.

[@thehvachacker]

No problem trying to share some info before it becomes mostly all repair videos again.

[@michaelb4512]

Does it matter if windex has vinegar in it?

[@tylerisham4769]

Good job windex...

[@thehvachacker]

The unknown leak solution we the leak the fastest

[@peterbrianmendonsa5643]

I checked a spilt Ac.when I start the Ac it runs for one or two minutes n then the outer unit stops.then again after two minutes it starts.pls tel me what will be the fault.

[@thehvachacker]

Hard to say without having the unit in front of me and my meter to test the electric circuit. Yet it sounds like a low pressure switch possibly causing this issue. Put your gauges on and see when it cuts out what the pressure is

[@peterbrianmendonsa5643]

@@thehvachacker the unit is one ton spilt Ac.n I checked the amps its 3.45.sir the problem is the Ac starts n after two minutes it get off the outer unite n then after two minute it starts.is the problem with the censor .

[@thehvachacker]

It sounds like it is cycling on low limit. You need to check the pressures to see what the pressure is when it cuts out and then what’s the pressure when it cuts back in. It can also be a freeze stat if one is installed. If the evap becomes to cold it will cycle the condenser off.
