Testing My Electronic Refrigerant Leak Detectors

- I need to use my electronic refrigerant leak detectors on a job tomorrow. Last time the HVAC leak Testers were used was last summer. I am going to be doing a refrigerant leak search on an ac system. This air conditioning system I found not cooling correctly during maintenance. When I checked the pressures I had to add 6lbs of 410a. So I am making sure I am prepared before going back and looking to see if I can locate this Freon leak. I am testing the Inficon D-TEK Select Refrigerant Leak Detector and the Inficon Tek-Mate refrigerant leak detector.
lol the birds are trying to sing back to the detector lol!
informative video, I have been using d-tech infikon for a long time. The most good device for searching for gas leaks
I like the d-tek I need to buy it a new battery but I know it works for when I get to my leak search job later today
Highly recommended getting an ultrasonic leak detector. They are amazing! We use the Accutrak and it has been undefeated in finding leaks these detectors in this video failed to find.
Some mistakes like a sensor not being able to read correctly is because they're turning it on within 5 meters of the refrigerant leak. Try to find some fresh air, turn it on, wait for 5 minutes if it's still inaccurate you have a magic arse wand :). This mistake was seen in a gas explosion somewhere because someone from a gas company calibrated it inside the building. The gas detection thing is using the same principle as that. And a word from me, these are designed on ENCLOSED spaces. Not on outdoor areas.
Yes but they can work outside if not too windy
I actually got nasty burns from an r290 unit before because i turned it on near it so i had no traces. I turned on the torch and yeah it blew up 😂
I’m trying to make sense of why my UEI Combustible Gas Leak detector was being triggered by the ground I was working on the other day. UEI still hasn’t called me back
@@thehvachacker DISREGARD MY COMMENT ABOUT HOW TO RECALIBRATE!!!! UEI CAN VOID ITS WARRANTY IF YOU DO THAT! THAT IS STRICTLY FOR ANYTHING BUT NATURAL GAS AND EXPLOSIVE GASES. Follow the UEI basic recalibration instructions on the manual. If it doesn't work, bring it to UEI for recalibration. IF A GAS LEAK IS PROBABLE, CALL THE GAS COMPANY IMMEDIATELY
I found a gas leak before the meter so homeowner needs to call utility company just the mulch was triggering the combustible gas leak detector. I called UEI yet haven't heard back from them.
Thanks for sharing
Moral of the story? Use R22 as a trace gas!
Inaccurate: Same problem I have with these small detectors. They beep everywhere there's no leak. They'll only find a real leak when you rub its nose in it, as you had to do. You spent a good 5 minutes probing 3 inches of tubing. Imagine how long it would take to do a whole system.
Same i face this problem that why i give priority to soup water....
The false readings is why I always confirm with big blu. These things are great until they are not. Which I guess goes for everything. Good luck on your hunt.
I like the D-Tek and it gets me into the area if not pinpointing. the other one in this video not so much. I use bubble solution cause if I don't find it with a solution I can't fix it.
@@thehvachacker i agree i like the D-tek also. Most time majority of techs do not use them correctly. I have found leaks when was unable to locate with soap bubbles/ leak solution. Thats cause depending on where coils leak you won't always see bubbles. ....
Yes then if it’s in the coil, which the older Lennox HS condensers we’re notorious causing me to cut away at the steel so I could braze it shut
Yet a coil leak usually means that component is toast unless it’s a u bend. I don’t know why most companies put the other meter in this video on most service trucks it doesn’t pick up leaks often.
@@pineychristian yeah coil leaks are a different story.
Hey mr hack, would you make a video on step by step process of hooking up a smoke detecter on a package unit. Thank u.
I can try the next time I have to work on one
@@thehvachacker It would be greatly appreciated. Thanks for all of your experiences.
@@carlosluna181 next time you put in a new one usually on the bid sheet you're right in there you provided the smoke detector the electricians wire them
I was trying to help the man out.
I still preferred the traditional way of leak detecting...most of the time electronic leak detector failed just rely on senses and experience its much better
That was the next video I recorded using different bubble solutions. Also my last video.
Which is better and faster? A sniffer or spraying soapy water
I usually use a bubble solution while recharging. If I don’t find and the customer authorized a leak search then I use the sniffer to get close to the leak. If I don’t find with the sniffer or bubble solution then a cut and cap gets done in the off season. I separate everything seal up as you see this coil and pressurize each component. Whatever loses pressure has the leak, which is usually not in a repairable location.
I made a second part of this using different leak solutions.
Isolation leak search on very difficult to find split system leaks. Fill or pressurize system 250psi nitrogen or more. Shut down service valves... Then you know what side leak is at ( inside or outside). Gives you good starting point.
Had to do this on system with underground linesets that were over 75ft long.
We do cut and caps which is the same as you mentioned except we isolate all the components. This coil failed one of my cut and caps why it’s piped how it is. I leave room on the piping Incase it has to go back into the system piping. Also pipe the lineset together and condenser can cap piping and just pressurize. It’s the sure leak test yet your talking leaving a customer down. When we do cut and caps we let the system sit for a week. Everything pressurized between 350 and 400 psi. Something is dropping?
@@pineychristian 500 psi and nitrogen one on Monday. No signs of oil anywhere. R410a
my infincon has been giving my difficulties latly finding leaks. getting alot of false readings. thinking about switching to ir detectors
They sell new sensors. The sensors wear out over time
@@thehvachacker just changed them monday. was leak checking yesterday kept getting false readings and didnt find the leak. think i exposed it to too much moisture and oil.
I bought an aliexpress model and it worked well until I think I got water in the tip or too much gas hit the sensor or the wrong type of gas hit the sensor. Anyway ordered another and will be more careful
Correct me if I am wrong but don't most Inficons Electronic Refrigerant Leak Detectors D-TEK & TEK-MATE & COMPASS use the same sensor ? Part Number:703-020-G1. Heated Diode sensor same technology as the Bacharach H-10 PRO.
The D-Tek Select uses an IR sensor the Tek-Mate and Compass have the heated diode.
How aboute small leak can this device do the work?
I now know what leak detectors ‘not’ buy
Please do test on elitech dual sensors.
Been using a DTEK for over 10 years. If you do not replace the sensor often it becomes useless. What you are doing is killing your sensor. If you feel it’s not working correctly just change the sensor.
How am I killing my sensor? I love my d-tek don't like the tek-mat. I do need to buy a new battery for it but it finds leaks for me all the time.
Over the life the sensor becomes saturated and does not pickup on smaller traces of refrigerant. So as you are looking for leaks. It will pickup on the larger leaks but not the pin hole smaller leaks. I know this because I became very frustrated with mine and couldn’t find a leak. Called up DTEK and they explained to me exactly what I explained to you. I changed the sensor and returned to the job the following week to find the leak in 5 minutes on a 5hp multiple evap +20° evap system . So by “checking “ your sensor you are hurting your sensor.
I hurt my senser when I take it out to look at it? I am on my 2rd senser and now it’s time for the battery to be replaced. The sensor is inside the handle. The filters should catch and trap the oils. My D-Tek picks up the little stuff still not the two-mat. The d-tek was going off in low and the two-mat missed it on a leaking evap I was searching the other day.i know the service life of sensor is around 1000 hours
Lol I’m not arguing with you. My tools are for making me money. I guess I don’t have the time play with old coils. Checking your sensor by turning the DTEK on and filling a junk coil with refrigerant it seems excessive.
It might but I wanted to make sure they worked since I had a leak search the next day I needed them for. The refrigerant was recovered 410 so not costing me anything. That coil I was trying to use for an experiment yet too many micro leaks after sealing the leak in this video
the wind is mess u up eddie leak master plumbin and heating in ct
It might be somewhat, or when I only had 25 lbs the leak rate might of been so fractional that I didn’t give it enough time to leak out for the detectors to sniff it. Once I bumped the pressure they were picking it up.the wind does give false readings on many detectors. It’s ok I just wanted to test them out for the first time this year before I needed them on a job.
what did you " Bump Up" the pressure to ?
Do you like the tek mate or the d tek better?
I keep the d-tek on my truck I trust it bx and find leaks better with it
Would this work on a car, as well...?
Yes it will work with 134a
Hmmm I bet that xc21 had your forearms itching for days damm fiberglass
Best way to find leak is dish cleaner foam
Lol
Robinair. TIFZX is the best. I've tried plenty. I've followed behind other HVAC companies that couldn't find the leak and it will find it in seconds. I've yet to not be able to find a leak.
I like the D-Tek I bought it back in 2007. I need to buy a new battery for it since the charge doesn’t last long. It’s so old it meet SAE for r12, r404a, and 134a At least if I need it I can plug it in. I’m not a fan of the TEK mat. It doesn’t find all the leaks and gives lots of false readings. As you could see in the video the wind was triggering it. I should of gave the refrigerant some time to start leaking before I started testing when around 25psi. I will see if either can pick up the leak I’m looking for after I finish troubleshooting this generator
@@thehvachacker anything with the heated pentode
With all due respect out in the wind, why no ultrasonic, like AccuTrak VPE-GN? Cost?
I do not own an ultrasonic and I am testing my equipment to make sure it works. Not doing a which is better. If I can’t sniff it with my d-tek a cut and cap is done to isolate everything and find out which part is leaking. I am mostly trying to bring the d-tek back to life I just need to order a new battery
I have been using a Ultrasonic for about 19 years with excellent results. When I find a system flat I pressure system up to 250 PSI with nitrogen and Ultrasonic goes to work. I have at least 8 electronic sniffer type leak detectors including a Bacarach H-10 PRO. I also have a UV Light kit to use with UV dye as well. The Ultrasonic is my favorite for refrigerant leaks.
thats gotta be a pretty small leak
lol plumbing
innaccurate and cant be struted
Beth loo horrible to me,
