Low Refrigerant? Freon Leak? Check This First!

80 percent of the calls received regarding refrigerant leaks are found at the shrader and or king valves. This is a simple test procedure to detect if your shrader valve and or king valves has a leak!

[@wsurfer2147]

My central AC has a leak. I called the local HVAC guy. He came over and told me I have a leak but instead of attempting finding the leak he offered to replace the WHOLE system from condenser to the ducts without even looking at my ducts. Hard to find an honest HVAC person !!

[@chizzlemo3094]

there are only 3 HVAC people in my area, all advised replacing the whole system for $5k, none of them even did proper leak tests. F these people!

[@melissanative1799]

SAME HERE. HE DIDN'T WANT TO CHECK THE SOURCE OF THE LEAK AND WANTED TO REPLACE INSIDE AND OUTSIDE COILS. THAT WOULDN'T HAVE RESOLVED THE PROBLEM IF IT WAS LEAKING AT THE VALVE. UNREAL!!

[@robertsarhanmd6433]

Excellent, Thank you so much, live in the North Carolina area and had my AC refilled last year and leaked out, the man said I need to buy a new system for 6000 dollars. I am unsure if I need one but I will be checking my shrader valve today, Thank you, Robert

[@stevenhedstrom5586]

You're a great teacher. Easy to understand and very informative for someone like me who knows absolutely nothing about a/c. Thanks

after the leak is fixed can the technician refill the Freon??

[@RayMacksKitchenandGrill]

I just checked my valve after watching this video...it was leaking...I have someone coming out tomorrow to check it out...thank you so much for posting this video.

[@janicesmyth2183]

what a great video! My grandson is studying to be an hvac repairman. This video will help him go a long way. Thank you!!!

[@dus10dnd]

Not only will the brass cap protect the valve better, but if the valve does leak, which is usually a slow leak, the brass cap will prevent the leak while it is on. Honestly, 90% of the time, the brass cap alone would be enough, but doing things the Right Way™ to do things.

[@Dasborg]

Thank you for the demonstration. I especially appreciate how easy it will be to check if the source of the leak is at the valve. My AC guy, will say anything right now to get me to buy a brand new hvac system, citing that the leak is in the evaporator coil, which is in the attic and virtually impossible for me to see for myself. At least I now have the opportunity to see if the leak may be at the valve as a mater of elimination.

[@jonathanblackburn3449]

Hey, thanks, man. Huge help. I was going to pay an HVAC outfit a crazy amount of money to find a leak but now I’m on the prowl myself.

[@michaelkohlstadt3502]

Hey Sam, I have the same AC unit 2002 vintage King and schader valves leaked. These are the high temp and pressure side, makes sense. Thank for saving me alot of money.

[@stupendouslife8128]

May 19 2020, I just paid $ 570 for leaking test and refrigerant refill, the technician will come back in 2 weeks, to check again if everything is working properly and refrigerant level stays at normal level. It looks so simple job to do, but I need to buy tools and refrigerant to perform the job, plus I do not know to much about A/C units, so I have to pay the price, thanks it is a very instructional video, great job.

[@stevee7774]

You won’t be buying any refrigerant unless you’re EPA certified.

[@jleron22]

Very informational video sir, You explained every step detail by detail, which makes any how to do video that much more enjoyable and fun to watch

[@mccallwd]

I had my 2003 R22 system topped up last year, tech said there was a small leak somewhere then left. This year I called another company who's coming over next week to top up the system. I'll perform the leak test myself tomorrow to see if I can pin point where the leak is and maybe save some $$ as the R22 is going to cost me. Thanks for putting this together it really helps...

[@marvinostman522]

I liked what you did after you replaced the schrader. You left the replacement tool on, opened the valve and removed the end of the tool in essence checking for a major leak before you pull the tool off. I hav e had a lot of people discount the schrader as the cause of a low system. Another thing to do is listen when you remove the schrader cap. If you get that psst, definitely check the schrader.

[@6barry66]

Better yet just tighten the Schrader cap like you're supposed to or the large nut on top of the suction service valve and then you won't have any leaks at all you are supposed to tighten those two covers. If you don't like the covers that you have then use the ones that train makes you tighten it with a 9/16 wrench it's solid brass it's very tight and it does not leak.

[@marvinostman522]

@@6barry66 why cover up a leaking schrader by tightening the cap over tight? The plastic caps won't always hold and the brass ones if you over tighten them you can deform the seats and when you do finally decide to change the schrader you can't get them out. I spent 17 years doing hydraulics and found over tightening the JIC fitting would make them leak. That is why Parker Hanifin came up with the FFFT method of tightening their fittings. FFFT stands for flats from finger tight. When we started using that system our leaks dropped dramatically.

[@6barry66]

@@marvinostman522 I think what you're trying to do is find a way to charge your customer another $300 the fact is the cap was made to be tightened not so tight that you destroy the threads but you should have no problem putting the flare nut that train makes on an air conditioner that has a really minor leak and tightening it or you could just use the change the pin valve on the Fly tool and you can just put a new pin in there. And this does not cost $500. I work with people everyday who find creative ways to gain the approval of their employer and padding bills and adding tasks that serve no purpose just so they can get commissions. And I know you know what I'm talking about because virtually every news outlet CBS NBC Dateline they've all run scams and they've all shown people what we do and right now we are in Industry under the microscope just do your job it does not cost $500 to clean someone's condenser it does not cost $500 to get rid of algae on an evaporator tray these are just cons to get extra money out of people and it makes all of us look bad. Right there on the front page of our industry magazine just about a year and a half ago was a headline and carrier and Linux and train and many people ask the question what's wrong with HVAC contractors. Most of us who work in this field did not need the negativity that was shined on us by a few unscrupulous people who can take the simplest repair and turn it into a 500 step procedure that cost $1,000. So do whatever you got to do I guess to feed your wife and children but this is the part of my job that I always hated and I always resent it where I was occasionally forced to price gouge people because I couldn't afford to quit my job right then and there and I had to spend a few weeks to find another job because I just didn't like what I was doing. And I did not feel good about what I was doing.

[@marvinostman522]

No idiot. I assumed you would be smart enough to change the pin valve. It takes sisolation calve o little time you don't even need to charge for it. As for the isolation valves make sure they are back seated and seal the caps. They won't be used near as often

[@marvinostman522]

Hit the wrong key. The isolation valves won't be used near as often as the access ports. Don't jump to conclusions about everybody. Could you send me an signed photo of yourself walking on water?

[@frankroper3274]

A quick fix if you don't have the removal tool is to buy some brass caps with o'rings inside them...not too expensive. Put them on tight and it will seal it off pretty much the same as the valve core does.

[@blueribb99]

Maybe adding a little thread tape first would help too

I bought the NU-CALGON Gold Leak Detector and tested both shrader valves for leaks. There was no signs of bubbles at all. I bought and installed the new brass caps to replace the old plastic ones.

[@TheWilferch]

What size are the brass caps?.....

[@visions4L]

thank you so much. that is exactly what people have been doing. I have been told so so many things , but no one has ever done this leak test. i have my line running through a concrete wall that holds up my deck. that is how the house was when I purchased. im praying leak is NOT inside line behind brick wall. refrigerant is totally depleted, just had refrigerant put in a few months ago and it is depleted. did not run unit over summer at all. im hoping this piece is the problem.

[@MoreThanMaintenance]

Let me know how it goes! 🙂

[@visions4L]

trying to get warranty to pay for new line or to find and repair leak. if leak in line that runs through concrete wall is main challenge. believe replacing line will be best.

if the leak was in the copper lineset, it would have leaked when installed and be completely empty, aka no cooling

good to see you replacing the crappy black plastic caps with a good brass cap, that will seal any leakage from a faulty schrader core. Also I didn't see you tighten the top cap on the 'king valve' those are to be tightened with a wrench 1/6 of a turn after they are finger tight. There is brass seat inside the cap that will seal any leak from coming out of the stem. Good points though...
