    The only issue I see with it is that R290 don't smell because it lacks mercaptan, something that's added to the fuel variant of propane.
    If you worry about R-290 then you should also worry about your phone, hair spray and cooking oil too.

  2. Avataaar/Circle Created with python_avatars Sovereign-WV Citizen says:

    Quite a few local HVAC don't want the liability issues. Ordinary refrigerants only.
    The EPA is not a law making body either as WV taught them. Congress only.

    Great Video. Thank you for sharing Service area Orleans??

  4. Avataaar/Circle Created with python_avatars anthony10370 says:

    On the contrary. I’d like to see more applications. Especially vehicles. We already have high pressure fuel under the hood why can’t we use r290 instead of the overpriced r1234yf ?

  5. Avataaar/Circle Created with python_avatars Chris Alessi says:

    Do you have the part number for the low pressure switch?
    I ordered one from Delfield and received a Danfoss adjustable one with conversion instructions.
    I found this to be odd for a R290 prep line.

  6. Avataaar/Circle Created with python_avatars Liam says:

    Its propane, not acetalyne. Its the same stuff used in BBQ or camp stove, or cooking, but in smaller quantities.

  7. Avataaar/Circle Created with python_avatars Brian Mc Dermott says:

    Great info. again. Thank you, Chris.

  8. Avataaar/Circle Created with python_avatars The Project says:

    How do you resist the urge to speak to customers in a Hank Hill voice saying "I sell r290 and r290 accessories"?

  9. Avataaar/Circle Created with python_avatars Dennis Olsson says:

    Non professional here.

    1) A propane gas can for camping stoves have easily 220+ grams of propane in it, so I feel the fear is way out of scope
    2) there are fire extinguishers that use SodaStream CO2 bottles. They are awesome and cheap to refill. As an alternative to the towel, not an alternative to a real extinguisher.

    Thank you Chris for the valuable information as always.. I have been apprehensive of working on r290 equipment..not scared..😂. Only because of the lack of the tools really necessary when working with r20 at my job unfortunately.. Time for changes my man

  11. Avataaar/Circle Created with python_avatars Frost HVAC says:

    It’s like going back to our junior days in the trade, we’re scared to work on something new. I use to be scared, and I’m not now. However I’ve heard of cases of these coolers catching small fires lol. Its funny, but eventually that’ll be the reason things rollback imo Service area Barrhaven??

  12. Avataaar/Circle Created with python_avatars Bait28 says:

    is there not a risk of flooding the closet you are in with nitrogen, possibly leading to asphyxiation?

  13. Avataaar/Circle Created with python_avatars Juan Todolí says:

    Here we connect a long hose from the service port and run it to a window for vent hydrocarbons. Propane & isobutane.

  14. Avataaar/Circle Created with python_avatars Ευάγγελος Θεοφίλης Ψύξη & Κλιματισμός says:

    Hi, mechanical engineer here, dealing with HVACR. Propane (R290) and Isobutane (R600a) reclaiming machines are not currently available, partly because it isn't mandated by laws and regulations. They have smaller GWP than most HFCs and HFOs ( if not all ) and no ozone depletion potential.

  15. Avataaar/Circle Created with python_avatars darksabatta says:

    I’m not scared of it just a little bit more time consuming however the company I work for seems like they give me all the r290 follow ups and jobs that have to do with sealed systems repair. Are you in Orleans ?

  16. Avataaar/Circle Created with python_avatars Tho mas says:

    Could you just burn of the R290, like with a little torch or burner?
    Deleting any danger of having an unwanted ignition

  17. Avataaar/Circle Created with python_avatars Sean Reigle says:

    Have you ever accidentally set off the smoke detectors while braising in those closed spaces?

  18. Avataaar/Circle Created with python_avatars Chad Armstrong says:

    How do you feel about triple evac?

  19. Avataaar/Circle Created with python_avatars John Doe says:

    I like propane systems. I've built my own for well over a decade because over systems are a bitch. I can literally use a basic transfer pump for propane with proper valves and accumulators AKA propane cylinders to build an extremely efficient system.

    Coldest I can keep things is about -25

  20. Avataaar/Circle Created with python_avatars Real estate services & sales Heating & Cooling says:

    I'm on the back 9, I get tired of all the new crap, but it is what it is.
    Bring back ammonia systems, it's a chiller. 🤣🤣😂🍺🇺🇲🇺🇲 Service area Kanata??

  21. Avataaar/Circle Created with python_avatars Thomas S. says:

    Delfield put out a service bulletin a few months ago saying to no longer use that leak detector and use nitro and 134 as trace gas with your go to detector.

  22. Avataaar/Circle Created with python_avatars Matt MaCurdy says:

    I’m a little terrified my crimp tool will fail when Im doing the final brazing on that hi side. 😂 Service area Nepean??

  23. Avataaar/Circle Created with python_avatars sean peterson says:

    My ex coworker recovered 290 with a recovery machine… nothing bad happened besides me yelling at him

  24. Avataaar/Circle Created with python_avatars Dan Presson says:

    Awesome video I was on a job where atech told another teacher to shut the breaker off and he said yes and the tech didn't double check and git hit by 460volts burned his arm from one side to the other he was in bad shape it was horrible

  25. Avataaar/Circle Created with python_avatars Wes M says:

    Not afraid to work on it. Buuuut dislike working on cooks drawers or prep tables. That one looks nice and accessible though. I replaced an evap coil on a true cooks drawer this week wow what a nightmare. Learn lots from your videos Chris keep the good coming!

  26. Avataaar/Circle Created with python_avatars Mark Seneca says:

    I use a dremal to cut out drier and then torch the joints off that me.of course use nitrogen also.

  27. Avataaar/Circle Created with python_avatars GrayWolf says:

    I get fires working on 404a, oil vapor will combust and catch burn the 404, even with nitrogen

  28. Avataaar/Circle Created with python_avatars Jorge Fernandez says:

    For those unaware, R290 is extremely pure propane.

  29. Avataaar/Circle Created with python_avatars Zac Cody says:

    Definitely not afraid of working on r290 but don't like working on r290 systems. My boss won't let me leave taps on anything running a hydrocarbon😑

  30. Avataaar/Circle Created with python_avatars Pro Answers says:

    Have you ever attempted to thread a 134a 12-ounce refrigerant can on that Atlas high precision scale?

  31. Avataaar/Circle Created with python_avatars Luke Eisenberger says:

    I service r290 units since when can you leave access ports on them. I’ve always been told you can’t do that

  32. Avataaar/Circle Created with python_avatars Arthur Hartwick says:

    Wetrag!!!!!

  33. Avataaar/Circle Created with python_avatars NJ Workshop says:

    If your not putting a full can of r290 in each unit are you even a refer guy?

  34. Avataaar/Circle Created with python_avatars Trey Ehli says:

    That Henny Penny error sounds haunts my dreams.

  35. Avataaar/Circle Created with python_avatars Jason Johnson says:

    I remember messing with my apprentice when he was pulling a vacuum….i kept hitting the compressor with my rubber mallet….he kept noticing his microns going up after going down……i kept quiet for awhile…he started to panic and didn't know what was going on…i finally showed him what i did….he was a little pissed….but started to laugh at it, after 5 minutes or so. He actually thanked me at the end for showing him that vapor, atmosphere can sit in the compressor oil/ the system and boil off/ be trapped.

  36. Avataaar/Circle Created with python_avatars RELIABLE HVACR says:

    Been wanting to work on them but there's only a handful down here and we don't service them yet Are you in Ottawa ?

  37. Avataaar/Circle Created with python_avatars Sayd Wolfe says:

    Why would you cut the service port off?

  38. Avataaar/Circle Created with python_avatars Doc Dat says:

    Not scary at all one just must work under the rigth conditions and be careful Are you in Barrhaven ?

  39. Avataaar/Circle Created with python_avatars kaptaintrips says:

    Agitate the compressor and see all the kitchen debris fall out of the unit… barfing

  40. Avataaar/Circle Created with python_avatars Danny says:

    My biggest fear is not being able to fix the problem.

  41. Avataaar/Circle Created with python_avatars Quantum Leap says:

    Thanks Chris for another informative and interesting video. Common sense and to-the-point commentary.

  42. Avataaar/Circle Created with python_avatars Mark Chapman says:

    Worked with it many times. Ultra low freezers use it regularly to keep the oil fluid.

  43. Avataaar/Circle Created with python_avatars Brendan Conley says:

    Just something to add, you said pulling a vacuum to below 500 then 200, absolutely do not pull below 250 microns because POE oil starts to gas off at 250 microns which is obviously bad.
