Man after my own heart. Turning vanes!!!!
My metal shop makes fun of me. Says I’m the only person that does resi work that puts them in.
I love them.
Why not rip out the metal above each unit for clean seams all the way up?

We just transitioned to what was there. Time is money I suppose, we have plenty of time if they have plenty of money. In this case their part was a failure on their part

Is that how tall coils are now?
What was there before?
Low boy, heat only?

Why waste time with the turning vanes and go for quality when you just scab and tape the old connections?? All that tape and how the tubing was ran looks pretty unprofessional.
I know you can do better. Not busting chops just reacting to what I see.

The house had a 4 ton undersized system as there was an addition added several years ago and we installed a 5 ton. The old system was a low seer smaller indoor coil (that was wedged into the plenumn with the top of the coil touching the top of plenumn)

I wish we didn't have to tape but code requires us to and the red lettering is required to be shown. Mastic isn't a thing around here. I may see mastic a few times a year. We did add a few standoff clamps to the vinyl. I appreciate the feedback

I think Mastic looks unprofessional , like a 4th grader did the install
I love Red/ Blue/Green Lettering on the Foil ....

You're telling me that lettered tape looks better than this?

Several years ago we did mastic on a job which looked descent i thought. The customer demanded we tear it all out, mask it all off and have absolutely perfect lines...

I do as much clear silicone as possible. I dislike both tape and mastic. So there.

That is nuts. What did you do? I assume you didn't kill them and bury them in the back yard since you are posting about it.

I'm tired of these mediocre "semi flammable" refrigerants. If we're going to do it let's do it right.
Unless we change direction we are likely to end up where we are going.

Educate them on the value of proper duct sealing and what PTCS is, and the potential savings it brings. I let me customers know beforehand how I will be sealing their ducts and they are smart enough to know the benefits far outweigh the negatives.

We bent over. We sent a helper back for a full day with like 10 rolls of painters tape and replaced a bunch of ducting. I dont think we have been back to the home since.
It was a referral from a good customer so we didn't want to burn too many bridges

I was talking with another sub at the supply house one morning years ago and he said he was subbing from a company that required straight lines like that all their rough ins....... better you than me...... I always kept things neat and clean but, masking off with paint/masking tape, not gonna do it.

It is pretty hilarious how everyone knows that mastic is the way to go, yet many come on and defend lettered metal tape, lol.
Let us all be honest here and admit you would be much happier with the way my project looks than that tape abomination.

Oh I'm totally with you mastic is the best.

I always thought it was funny how you hear about how "efficient" sealing ducts is, until I realized that most of the world is not Wisconsin. Around here furnaces are almost always in the basement, and the basement is part of the conditioned area. And there are always supplies cut into the main trunk line on unfinished basements to condition the basement, so spending a bunch of time sealing the duct is a waste, as your going to be cutting in supplies that dump air into the exact same area. 
The only times we spend seriously sealing ducts are in unconditioned areas, or if there is zoning going on, and a finished basement happening. We still seal the obvious stuff right at the furnace mostly to keep it nice and quiet, and especially around the filter rack past the filter to keep unfiltered air from sucking through the system.
As to mastic versus tape, I personally think they both have their place, and around the furnace, and coil I think mastic is a horrible idea, some day a guy is going to have to take that apart, and we all know how hard it is to peal out a drive that is mastic in. I agree that mastic makes for a better and longer lasting seal though.
To the OP, I like the idea sort of, but why not just go horizontal? My biggest problem with turning vanes in resi is that people like to get duct cleanings these days, and turning vanes are worse than hand dampers to hit with a brush inside a duct....
I r the king of the world!...or at least I get to stand on the roof and look down on the rest of yall

Great point and something I hadn't considered. We too have basements here which are in the thermal envelope of the home 95% of the time and your right, sealing is a pretty big waste of time. When the customer *****es about a small Air leak from a seam and also wants a supply register in the basement 10' away in the same sentence it can be comical
