How to find a refrigerant leak in an air conditioner?

[@dalemihocik4732]

I like how you gave the customer options and didn't judge him on what he chose. I need to find an independent contractor because these company guys are driven to force service contracts and high end equipment down your throat at every given opportunity. Maybe I'll get lucky and find a guy like you.

[@TaddyDigest]

Thank you yeah I just want my customer to be happy. I offer my advice and it's always just what I would do if I had their situation. I agree with you A lot of companies are just driven to make a sale and they don't care about the customer

[@ronniehvac653]

Hey Dale, I hear ya brother. I work for a company in the Hudson valley in NY. A lot of competition but countless number of times I'm servicing equipment with the competition's sticker on it. I always try to be as transparent as possible. I've learned that once you lose a customers trust, you've lost their business.

[@Minimarshi]

@@TaddyDigest I have the same issue, lost about a pound in a year. Have had 3 companies come out only to not pinpoint the leak, guessing it's probably on the back of the evaporator coil like this one. What did you recommend replacing, the coil or the whole handler?

[@DrAlexanderHamilton]

BEST COMMMENT. This describes my situation. Every person I've had out is trying to get me to buy an entire new system when my system is only 8 years old. hard to find good honest work.

[@DrAlexanderHamilton]

@@ronniehvac653 BINGO. HVAC techs in our area have a bad reputation for ripping people off. We've been taken advantage of too many times to count.

[@ParabellumX]

I use Fieldpiece's DR82 Infrared Leak Detector. It's freakin awesome! I do a 3-hits-it's-a-leak check, but I really don't have to; if it goes off, there's a leak (or I accidentally bumped the tip on something). Probably the greatest feature about this particular leak detector is the fact that it gives you three signs to let you know that there is a leak: there's the audible sound, the flashing of the tip, and a vibration throughout the leak detector itself. That's awesome! So it doesn't matter if you're blind, deaf, or dumb, you will find a leak if there is one!

CPS leak detector is the best. We had a leak on the R114 plant and it was like chasing a ghost. We put soap on the area and it took about five minutes and the bubbles were so small it looked like shaving cream. That's how small the leak was.

[@OcRefrig]

Good video ! But Here’s some tips from a Guy doing it for 42 Years. 1) if System has at least 1lb of liquid refrigerant in it. ( 410a systems ) Just pull the disconnect. Wait 5 min for system to equalize. Equalized pressures on 410a system at 60 degrees outside with liquid in it will be 170Psig. Higher if its hotter out. See pt chart. 170 is plenty to find a leak with a H10-leak detector or any decent leak detector. 2) Most Leaks are in evaps. 75% of the time. Start there first. 3) Rarely have i needed to pressure test over 150 psi to find a Leak with a Ge H10 leak detector.

[@stevenross9271]

I have been doing refrigeration and air conditioning for over 45 years. I am partial to my Inficon select. I spent 30 of those years behind a desk as a service manager. I diagnosed techs problems over the phone. Always look for a leak if the unit is low. To just add gas is not performing your job.

[@stevenross9271]

The G.E. H-10 with a cord is without a doubt the best leak detector you can get your hands on.

[@eethridge4065]

That rare time is that dang ice machine that passes the pressure test twice and has a fan switch that doesn't leak until it hits 275 psi high side....ugh

[@srobeck77]

The common census for leak checking is to raise the pressure no higher than the highest rating on the low side. Its to avoid damaging the internals of the system.

[@rwood1995]

That makes it hard to sell them those items though dont it?? 🤑 JK LOL

[@g-lato9791]

Does that also apply to the heat pump tho , since it is reversible and they both use the high pressure

[@srobeck77]

@@g-lato9791 incorrect. This is a lack of understanding right here. In a heat pump, the high side just alternates between the evaporator and condenser but is still same high side pressure reading to go off and you should not exceed that number.

[@terrimcglothin2230]

If I can't find a residential leak with an electronic & sonic leak detector within 30-40 minutes , I like to add fluorescent dye while I add refrigerant. This provides comfort cooling until we can reschedule the leak inspection, and let the dye have time to show up After 35 yrs in residential, if I can't find the leak in a half hour or so on most units, then I know it is going to be a tricky one. The uv dye really helps to pinpoint the problem. Owner operators.. Remember, dye is a tool to help you. You dont need to make a fortune on the dye. Be fair to your customers. You will earn a fair profit during the repair or replacement of the coil.

[@TaddyDigest]

Thanks for the reply! You were right - my leak was at the evap coil on my old R22 system. . According to the tech it looks like a slow seep - hopefully the stop leak stuff will fix it as a new coil is $4k so may need to get a new system. Other than this leak the compressor is running strong and the system has been well maintained.

[@renaissanceman5847]

I feel for the home owner... but the best thing to do is have some window units ready... 3 units are more than enough to keep you comfortable enough when SHTF with the main AC. they cost $150 each. Then with an older system, especially one approaching 20 years... just get the full install. else with and older system you may find yourself spending more money over the long term vs a new system plus the inconvenience (they always break on a Friday afternoon ) constantly fixing issues as its dies. At least you can get a warranty on installation and equipment that will cover you for a year or more. I also recommend insisting they inject UV dye into the system upon installation or even service. that way its easier to find the leak should one creep up at any point due to installation errors or aging.

I use the Testo 316-4 for R410a systems and the Testo 316-3 for R22, but the Inficon Tek Mate is also great option for r-22 systems ( I also have a Inficon tek mate). The Testo 316-4 is probably the most sensitive electronic leak detector I’ve used for r410a.. and I’ve can’t even start to tell you how many electronic leak detectors bought then sold trying to find a good model. Do a Search for NathanHVAC electronic leak detector sensitivity test. He has tested most of the leak detectors I’ve purchased. He has made spreadsheet of the leak detectors and their sensitivity for R22 and R410a refrigerants. I’m trying out Ultrasonic refrigerant leak detector this spring/summer to see if that can help pin point small leak’s faster.

I've used several ultrasonic leak detectors and found that they were useless when trying to find small leaks. See what the return policy is on the tool just in case. A good way to test it is by using a calibration vial.

I would not recommend to anyone to go 500psi on a leak test. I, like Oc have been doing it a long time. Never pressure tested that high, even on the commercial side of things. Can get dangerous. Usually there are operating max pressures listed, I would not exceed those. There is a leak detector that works via sound. I had one of those as well, no matter how small the leak, it would sound like a hurricane in your ears. Nice vid.

Plans to check for leaks on inside unit, weld leak if doable, install "stop leak", and new type refrigerant. If systems loses refrigerant, he will deduct charges from total price for new inside unit (or replacement coil) .

If it's a large leak in an air conditioning system it's usually on the high side of the system To check the condenser hook up your high side and low tide gauges turn off the power remove the condenser fan motor from the top of the unit Turn the unit power back on checking the high side pressure with condenser fan motor not working the high side pressure will increase to a point where you might be able to locate the week much easier Do not exceed momentarily 400 PSI Turn off the power check With an electronic leak detector You can also use an UltraViolet leak detector After injecting and allowing the fluid to circulate throughout the system One other method is using nitrogen to build up the pressure to see if we could find a slow leak using a Ultra Violet leak detector after injected fluid All these methods MUST only be performed by specially trained air conditioning service technicians with years of experience Absolutely no homeowners should ever attempt these leak detection procedures which could cause permanent bodily injury or possible death Leave it to the professionals

[@tiffanyperry9624]

Without keeping this too long. Unless you don't mind you can respond and help me. Basically this is the second central heat and air system I bought in 3 years. Because I'm dealing with American home shield warranty, everybody run no one use them anyway. Brand new system. They left rags, bolts, wires, all kind of stuff in the air handler. After that it still kept freezing up about 9-10 times. Then they said it was in my ducting so they retape that and then totally lied and said we never had mastic at all. I had a second company come out. They got up into an area where the company that lied never even got before. They couldn't even fit there. He took pictures and showed your mastic is fine. I forgot to also tell you the first company that installed the brand new units already has replaced three parts on it. The t-valve, the capacitor and something else. I don't even know a brand new unit. This was all in the first 3 months. I got it put in this February and here we are still waiting with a huge electric bill in this little house every month and having to keep the air down. The last guy that came without testing anything like you just did said it's your line set. Yep that's it.. no testing at all. He just put his head up underneath Air handler and said yep it's your line set. Now I know when you get a new system they are supposed to test and make sure the line set even fits your new system. Well this house was built in '96 and like I said the first system when I bought the house 20 years old it had a 3 ton double pump system. The second when I got ripped off it was supposed to be a 3-ton. He put a 2 and 1/2 ton and didn't even change the air filter air handler. Excuse me at all. Left the old one. And with a brand new one I just got. I know already they lied because of the mastic. I have proof of all this in writing pictures. Everything now the company wants to charge me out of pocket $1,000. Which by the way I've already paid $500 out of pocket for window unit after just buying the brand new AC unit. So if it's the line set when they haven't even checked it, he said it would be a simple thing to replace. Even though it's underground. You would just have to remove the air handler. Have somebody at the other end push out the old bring in the new put in the 2 lb of refrigerant and that's it. My question is $1,000 for this all because the word access was used. The company wants me to pay and no one's even tested it. So should I have them replace the whole thing since they've already replaced three parts on it? And we know they've been lying though about stuff already with this new company. If they won't change the wording then they want me to pay $1,000 for something he didn't do any kind of testing on. What do you guys think? I need some good advice and dealing with this company. It either is I have to come out of pocket $1,000 or I keep paying extremely high $300 and something dollar a month electric bill. My house isn't even $1,500 square feet when my 20-year-old system was here. I paid $180 in the summer. That's it. So what do you think the whole thing replaced? Do you think it is the line set with it being brand new? Maybe the line set is not brand new. It's original. They probably never even tested. It changed it nothing. And I guess that's not something you have to replace when you get a new unit. So if I have to pay out of pocket this seems like quite a bit for something he has said on camera. This will be a simple fix and won't be hard to do so. Do you think definitely I should have it tested? And also he said he couldn't add refrigerant now that he knows there's a leak because that's illegal. And how does he even know that it is a leak if he didn't even test anything? I'm going crazy. I said I'd keep it short. It's not short. Sorry. I'm just hoping you guys can see this and give me some good advice cuz at this point it looks like I'm going to have to get a lawyer. I don't have another dollar to spend after just paying for two units, a window unit and high bills and for them to come out. So please tell me what your opinions are. I need some good advice from somebody not trying to rob me for once. That would be amazing. Thank you and God bless you all

Most refrigerant leak detectors are incredibly sensitive. If you add any refrigerant you should always do a leak search. A basic leak search only takes 10-15 minutes to make sure you don’t have a good size leak. You don’t have to reclaim the gas and add nitrogen, the refrigerant is the gas you are looking for, and soap bubbles will also blow bubbles regardless if there is nitrogen, as long as there is pressure, don’t complicate it. You can’t give the customer the choice you are supposed to make as a trained technician when it’s such a simple move and avoids callbacks

Technician said had freon leak! On evaporator! $. Ouch! He put leak seal! Looked like a syringe. What are you thought on leak seal. After a month, failed to cool again!

Find the leak and fix it

With the industry going through a major shift to A2L refrigerants starting in 2025, does it make sense to install a current system based on R-410A or wait until next year for A2L systems?

[@TaddyDigest]

If you don't have to replace your system, now I would wait

[@TaddyDigest]

I will figure it out and get back to you

If my condenser is 14 years old you think it’s better to just replace it?

H10 with the long probe

My unit froze up the lines are copper so I turned the unit off so it can thaw from the big ice block so would that problem be from having a leak in the system? Thanks in advance

[@TaddyDigest]

Could be from leaking refrigerant. Could be from a dirty filter. Could be from low air flow. Just use a process of elimination to figure out.

Can I use shampoo as well? Thanks for sharing.

[@TaddyDigest]

I'm not sure

Hey Tad. What's the 1 to 98 countdown when the wind free units shut off after cooling?
