Where you come down on your vertical, it looks like 10x25. At the top, make a 20x25 to 10x25 transition. This usually makes a dramatic reduction in pressure drop
On your return drops, use a transition to utilize the full size of the return at the top and then reduce to your drop size.
Use tape on the lineset and then use a zip tie so it doesn't eat thru the rubatex

Thanks! I know what you're talking about on the zip ties. Generally I don't pull then tight enough to deform the insulation and try to avoid using them to hold any weight only to keep things tidy. I'm sure I'm still guilty of it but it's been an on going battle with helpers pulling them as tight as possible before clipping them.
On the return drops, I also agree with you. It is something I do a lot, but perhaps should just start implementing on every install. Pictures will coming in the following days. I've got a lot of install pictures backed up since I last participated on here.

That furnace with the returns on either side, why is the left return layout like that? You did a nice job of reworking it, Im just curious of why it has such dramatic directions changes at different elevations.

This might give some better perspective. I guarantee my new return was bigger than necessary, but it only helps static pressures. Had to tie into a panned floor joist.

Make sure to keep the lineset out of the way of the heater incase you have to slide it out.
I remember 10 years or so ago, on a downflow, they ran the lineset up thru the floor in the front middle of the unit blocking the heater from sliding in. It was pretty funny.
This one I wish I had a before picture, no ac, but had an old 80% on homemade legs pulling the return from the bottom, no filter, in a closet. It got tight fast in there.

It clears, I kick myself all the time for my drier placement on hyperions. The heat pack will slide out but I made it a bear to get the screw out! I had a trailer furnace a couple years ago that the lineset was blocking the blower from being removed... i feel your pain.

Yes and all but twice, yes. Once they didn't have any and the job needed done so I fabricated my own. The other time was simply an oversight since we usually keep an extra one in stock, so I made my own. Definitely saves the day when height is an issue. I pretty much do side/ bottom returns on every hyperion these days. Also does wonders for static. I even do it on 1 1/2 ton systems.

This is another one I'll have to find a before picture for. I can count on my fingers how many 100k+ furnaces I've installed. This was a 100k that replaced twinned 120ks. Was a monstrosity. I wish I would have worked in a second return drop somehow and a second filter but the static wasn't terrible without it. That's the old ac that I literally had to climb inside to clean multiple times in the past and had a 90 mfd cap on the compressor.

Riser under furnace and spacer between furnace & media cabinet. Nice. I hate the small openings on the S series furnaces. How about the 80s? Just heard one this week. Probably noisiest furnace on the market.

Thanks. It's become my standard practice, at the very least spaces but risers if space allows. I try to pay a lot of attention to airflow so anything to improve it on the return. I'm not a huge fan of the small opening either, especially when space is tight. I've only installed 2 S8's, both in attics and thus not a big issue on the noise. I've heard that from others though.

Just a fyi. Electronic air cleaners can create ozone & odors when connected directly to a tight 90 due to extreme flow variations.
Air flow needs to be fairly even across the elements. Couldn't tell if turning vanes are installed.
Installation:
The Electronic Air Cleaner is adaptable to all new or
existing forced air heating and cooling systems used
in residential applications. Transitions or turning vanes
may be required in some applications for effective air
cleaner operation.
Transitions
For most efficient air cleaning, spread airflow evenly
across the face of the air cleaner. If the duct is a
different size than the electronic air filter cabinet,
gradual transitions are required. Follow these
guidelines when fabricating:
• Use gradual transitions to reduce air turbulence and
increase efficiency.
• Use no more than 20 degrees (about 4 in. per
running ft. (100 mm per 300 linear mm)) of
expansion on each side of a transition fitting.
Turning Vanes
If the Electronic Air Cleaner is installed next to an
elbow or angle fitting, add turning vanes inside the
angle to distribute airflow more evenly across the face
of the cell.
Offsets
If the duct connection to the furnace in a side
installation allows less than 7 in. (178 mm) for mounting
Electronic Air Cleaner cabinet,
The only electronic air cleaners here are the one I took out. Honeywell media cabinets are about all I use any more. And there are turning vanes in pretty much every drop 90 I make unless it has a radius throat. Sabre reason though, even air distribution across the entire filter.

Taylor, where do you buy turning vanes? I can never find them in any supplyhouse?!?
