    Walk in cooler call unbelievable 🤦*♂️

    Cooler wasnt working. New customer. Suction pressure/temp was off. 404a box. Something wasnt right. Sight glass clear and saturation temp was the same as my box temp. WTF? Was with my nephew so was the perfect call to check what the superheat and valve was doing and show him how to adjust it. Till I noticed there was NO TXV. WTF? I looked again, and told him something is very wrong or Im going to learn something. Double take at solenoid valve. Electronic? NO. Started asking customer questions he said wasnt going below 45 and was working right. I asked when box was installed. 10 years ago. Then he said well no the coil was just installed 2 years ago, was working fine. Ya right. I was going thru paperwork looking for info. He then said who installed it and said the company that did was on Lafayette Avenue. I told nephew button it up and get me model numbers, and then told customer ummmm sorry its never worked right and I know who the company is on Lafayette, and I use company loosely. I told him its never worked right and the dumb SOB forgot to install the TXV. I sent it over to my supplier and in email I said Brian I think Im missing something can you help. He calls me laughing, I think hes still laughing. Never in 25 years or his 30 years have I seen something like this. Im assuming this appliance guy and his gang of hacks thought the distributor nozzle was a metering device. LOL I just cant believe this. Box got down to 45 ish and has been running non stop for 2 years. Who in the F does shit like this? The valve was with equipment supplier checked and I saw packing slip. Wall of shame

    How the heck was that thing keeping temp?
    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?

    Did it even have a nozzle?

    Could be the only way it somewhat worked

    Must have been the same "company" that installed this amazing WI Box door (which was purchased at Home Depot).

    Low bid.

    I recall this being reported here on Htalk once or twice before. If they "worked" at all, they would definitely need to have a distributor nozzle installed.

    Some sort of nozzle may be making it work. The OP should check for that before putting in the TXV. Don't need 2 metering devices on one system.

    Actually, with a pressure-drop type of distributor like the ones made by Sporlan, you DO need both the TXV and the nozzle. The nozzle isn't there as a metering device per se. It's needed for equal distribution and it must be accounted for when selecting a TXV because it significantly affects the available pressure drop.
