    Great job I'm a residential Hvac guy and Ive always wanted to do refrigeration just not many opportunities around my area to learn it real well but I learn something new every time I watch your vids please keep them coming

  2. tcpHVAC/R says:

    I appreciate your vids like this, because when I run into reefer calls at school, I like to have an insight on your troubleshooting skills. I know your pimpin' out the DL429, and when asked, I tell folks for $200, she's the best piece out there!

    That crappy drain freezing up was more likely due to air being sucked in through the open connection than from heat transfer.

    Also, that Dunham-Bush ECLS-65 evap was designed as a draw-through coil, not a blow-through. I'll bet dollars to donuts the installer screwed up and had to change the fan blade.

    One thing I've seen in the past, is to make a metal tab (usually from aluminum sheet metal or a strip of copper) that wraps around the drain pan heater and sticks down into the drain nipple to transfer the heat from the drain pan heater into the pan nipple to keep it clear.

    Thats a Very difficult one to diagnose But, i think u Nailed it ! i don't like those Heating Element Connections. does not look,like a good connection method. kinda funky.
    Wow, an Old 1981 Dun & bush. Evap ! Thats the Oldddd Time Quality ! Those old freezer evpas seem to last good from that era. i've got avid up of that one i rebuit with that old flare nut city on that expansion valve.

    I've been ignoring an ice buildup on the floor of of a large WI freezer at the track, but its starting to resemble an ice skating rink in there. Copper drain line split somewhere…time to get the coat and gloves, there is a LOT of product in there!

  7. Refrigeration Technology says:

    Hi Dave.first i must say that i started watching your videos about six months ago in ac class… three months later i got my first job in refrigeration.. and today i had a drain line heater kick my ass during a service call. Keep putting out videos. You are inspiring a whole new wave of techs!

    Quick question though, map gas wont damage any of the housing for the evap coil or the coil itself? Seems WAY more productive than using a pump sprayer filled with hot water

    My experience is that cable ties, especially the white ones, tend to stiffen up and crack after a few years. You might have been better off using some copper wire to hold it up. However, done is done, and that should certianly last a few years.

  9. Craig marshall says:

    Hey Dave any tricks for like when you are replacing a txv or old compressor to get out any trapped Freon on out so you don’t the killer gas ? I did purge with nitrogen and did a vacuum what’s the best way thx
