If you served my area I would never try to keep up with mechanical continuing education…I would just hire your company. You’re one of the rare few who understand craftsmanship.
This is the type of thing we do in commercial work all the time. I did a brief stent as GM in a residential HVAC company that did about 20% light commercial work. Technicians, the installers, hell , even the owner didn’t know what to do with a piece of unistrut. They were so used to going in, rushing through a job, and being done with a complete install by lunch, but when I came in and did things the way I was used to doing them they thought we were going to go bankrupt by slowing down and doing a nice job. Everyone agreed that it was beautiful work. They were proud of it. We were charging appropriately for it. But they still wanted to charge the prices I was charging but do shitty work. It was embarrassing and I didn’t stay long.
Dude you have no idea how grateful i am for this video. Im a resi tech who started off in installs, but no one could explain this to me clearly. This video explained everything perfectly
Awesome. Never found such a great video with great explanation of hardware used, procedure, pros and cons, all from measurements to installation & finishing. Amazing. Thanks a lot. Would like to see more from you guys.
Nice! I just had an incident with my upstairs unit and now understanding how poorly it was installed... this gives me the confidence to hang it myself. Cheers!
Great video! Loads of information, thanks! One addition for anyone that needs to cut threaded rod and doesn't have the tool for clean cuts is to thread a nut onto the rod before cutting. After making the cut simply remove the nut and it cleans the threads up as it's being removed.
Crazy I was just recently came across your old round pipe insulating video and days later you came out with the updated version. Very helpful tips I picked up especially on wrapping 90°s. Wanna bring metal fab to my hvac company here in Texas.
Yeah, I learned quite a lot. I learned the jackholes who originally hung an oversized electric gas HVAC system *directly screwed* vertically into the joists on only 4 points under my dining room were complete fools and had no idea what they were doing. And the guys who say that the vibration can’t be mitigated (“because it’s old”) Just want to sell me a new one. It looks like a lot of equipment available to significantly reduce vibration and maybe extend the life of my unit a few years least produce the vibrations, which are now becoming a real problem
Thank you for putting out quality work. I’ve learned a lot from your videos and looking forward to see more. As owner operator of a HVAC company it’s good to know that my quality of work is not bad compared to your.
I love your videos - keep up the great work! I agree with you on pan sizing - I've seen shorter than the coil cabinet on some installations - - Mech Code: 307.2.3 Auxiliary and secondary drain systems. The pan shall have a minimum depth of 11/2 inches (38 mm), *shall be not less than 3 inches (76 mm) larger than the unit*
Great video, really love it! Going through HVAC install in my house now, and this gives me some great ideas to look out for when the contractor installs the unit! Unit going in the attic and your tips will help me to make sure it looks clean! Thank you so much! Subscribed for more info.
Another idea for hanging equipment with threaded rod: Spread the top attachment points out wider than the bottom attachment points. For instance, a 48" x 48" pattern for the Sammys at the top centered over a platform with a hole pattern at 40" x 40". The platform won't swing at all.
@@aglmechanicaltips are you referring to springs in vibration isolator hangers? The tension is still parallel to the rod, so I can't see how that would be an issue
Bandsaws work exceptionally well with all thread as long as you angled bandsaw blade slightly away from perpendicular so that it's cutting in between threads
Awesome video. Best hvac stuff out there. Andrew, what do you use to strap up your main round trunk line? It looks like 1 inch metal banding. Is the flex webbing (2 inch) sufficient for like a 30 foot reducing run? This is going to be insulated duct. Thanks
Webbing is strong stuff. I used metal on hard pipe and webbing on flex. This is personal preference. The webbing should have a data sheet that can outline the weight rating. Make sure you fold the ends where you screw so the screw won't pull through the webbing
I'm in an old house that got a small attic unit put in about 2 yrs ago. It doesn't vibrate "much" but I still wish they'd suspended it, even if just a few inches off the bottom surface. Depending on where you are upstairs you can kinda hear/feel the vibration and it would be best if it weren't present. It seems to have the pan and a support under it, including those gray footers, so it might not take too much for me to add a basic suspension system like you show here.
You could more than likely leave the pan where it is and just suspend the air handler and remove the grey risers below. It would definitely help with vibration if not eliminate it altogether.
Andrew, when you suspend a gas furnace and coil horizontally how do you handle the gas line comnection? I just did this exactly as you show with a platform, unistrut, threaded rod and sammys. The unit can move swing quite a bit if you bump it or maybe from vibration. I would rather hard pipe but it seems flexible gas connector may be the better choice to handle the movement. What do you do?
You can run hard pipe gas line to the appliance but need to use an appliance connector at the unit (appliance connector is a 2' or 3' piece of flexible gas piping).
Depending on the weight I would probably bolt unitstrut between a couple of them to spread out the load and then build my suspension off of that piece of uni strut. Similar to what I did with the floor trusses shown torwards the end of this video but this piece of unistrut would be below the truss not above. This is difficult to properly explain..
PLEASE EVERYONE, do not use any type of grinding or cutoff wheel on your angle grinder without attaching a proper guard! Safety glasses alone will not protect you from fragments of a broken cutoff wheel flying toward your face or neck at mach jesus.
Bro is in a 120-140 degree attic filming content 💯

Have you ever tried cutting strut with a cordless bandsaw? It'll blow your mind how much easier it is than a grinder
Nice! I just had an incident with my upstairs unit and now understanding how poorly it was installed... this gives me the confidence to hang it myself. Cheers!

Your reputation is quality. Andrew your continent is awesome We’d love to see more videos.
More content coming in the next two weeks! Thanks for the support!
Your videos are gonna blow up over time. Keep making videos. Some of the best I've seen. Thanks.

We plan to add some metal fab videos in the near future.
I’ll be waiting for the notifications!

Keep on making videos please! Great content.
Hot in that attic, I feel your pain. Beautiful work! Love the platforms. Subscribed.
Much appreciated!
Loving the videos Andrew. The technique and attention to detail are inspiring!

Again, another outstanding video ! Keep 'em coming please!
Wow, this video is on another level.
The only comment - please post more videos 😉 Great tips and great presentation. All the best! 👍
Thanks! Two more videos coming very soon!
Great information......thanks for sharing tips and experience.

Nice job!
I appreciate that! I'll try to keep it up.
Nice bro thanks
Great videos Andrew! Beautiful work sir.
This info is priceless. Really, thanks.
Good information. Much appreciated
Great Job!!! Very professional videos. You should do some service oriented vids. lol.

Springs won't sit right if you spead them like that

Thanks for the videos !
Where is the install and what is the building? I like the lightning protection routing behind you.
Very interesting video! For something like a condensing gas furnace, is there a way to vibration isolate the combustion and exhaust PVC pipes?

They make plastic caps for the threaded rod ends.They just tap right on. Saves your head.
Yes they do, I even brought these with me and meant to apply them for the video but it was a long day and I overlooked that detail.

how do you hang unistrut on roof trusses vs rafters

Similar to what I did with the floor trusses shown torwards the end of this video but this piece of unistrut would be below the truss not above. This is difficult to properly explain..

❤ Sammys
Horizontal should of been in the attic and the vertical in the basement
Very useful. Although using those whacky inches and feet nonsense makes it hard to follow…
Nice work.
