    Hands down the best explanation of “how to” video. I am super impressed by you taking the time to explain everything including the expansion tank. I am still new to hydronic boilers so this is a blessing to see first hand.
  • @hansangb
    Straight and to the point with pro-tips. What more could you ask for in a "how-to" video! Thank you
  • @samabner2450
    I had three different hvac companies try and get the air out of my system, no luck. Watched this video and did it myself, worked perfectly. Can't thank you enough.
  • @teenice894
    I love the fact that you had 3 zones, it gave us the chance to watch you demonstrate the process 3x.... my second floor has no heat and all the kids rooms are up there. I will be doing this tomorrow. 🤞🏽. Thanks

    Thank you so much! You make this look easier than it is!! Really appreciate the time and info you put in this video! Ps. Keep them coming!!

    Concise, but thorough. Almost called a plumber because of gurgling even after using the little air bleeders, but this procedure took care of the noise! Showing us not to let the valves get stuck open as well as to cap off leaks gave me a peace of mind for some reason lol. Thanks much.
  • @eduardherri7991
    I did this a few times myself without knowing exactly what I was doing. I just made sure the pressure in the system was alright. You video makes sense and now I understand better how it works. Thank you so much.
  • @toddrengel
    Great video, thank you! It helped me purge air from a closed loop marine hydronic heating system with a manifold. Same exact principals and it worked like a charm. Really appreciate your clarity and breaking down what’s going on.
  • @chriso5194
    Thank you a million times! I've been searching for hours for information and this is the best thing I found. Fixed the heat to my sons room.
  • @joanlazcano2695
    Awesome video man! Simple to follow and right to the point! 👏👏👏
  • @Mhauptmanl
    Great video! Clear instructions with lots of helpful pointers along the way. Helped me solve multiple problems with my HVAC system. Thank you!

    100% best video I’ve seen on the subject. It’s an extremely easy system to bleed once you know what you’re doing. You made it as straight forward as possible. Now, I don’t hear water rushing through my pipes. My puppies are creaking when turning on, but so much quieter.
  • I dont normally comment, but you do a good job at covering all the details that are very crucial. I work in trades as well, and I can tell you know your stuff. I’m replacing a friend’s expansion tank and needed a good explanation on the system. Other videos suck at explaining. Good work
  • Love when the "why" is explained along with the "how". Great video - learned alot more than I set out to...always a good thing. Thanks!
  • Thank you so much for this video! My husband and I are first time homeowners and had never lived somewhere with baseboard heating until we bought our home. We were getting worried when we started to hear all that noise coming from the heaters but your video popped up when I was searching on what could be causing it. Took us all of 15 minutes to fix after watching your video, no noise since.
  • @JOEZEP54
    I do a lot of my own work & always looking for procedure & tips. This video gives a very clear explanation. Also not turning the valve all the way to open position is a tip many may not have known of. Nice job BIG .👍. Stay safe, Joe Z
  • @dabugman6415
    Best, well explained video I've ever watched on this subject. Thanks!
  • @bobbyw9046
    Followed your tutorial yesterday after replacing the expansion tank, automatic filler valve and pressure relief valve - worked like a charm!
  • @kmarks66
    Besides being an excellent explanation for how to bleed the system, it's just an overall great video. Very informative, no time wasted, no nonsense yacking. I just bought a house with this kind of system and I wasn't familiar with how it worked. Thank you for posting this!!!
