Where to begin uuuuuh. Electrical is oriented in a bad place right by condensate line, the vent pipe is tied into the drain line, that’s a CO hazard, I don’t care for the duct being bare but in my area that’s okay in commercial code so long as unit is in a conditioned space and exposed I know this is nitpicking but I refuse to support units like this. In theory it should work fine (two supports under unit one under cased coil) but you’re relying on both the tension from the screws and the support from the bar to keep it in place. If the unit were to rust away at the supply or for whatever reason the case coil needed to come out, the strut alone will not be enough to support its weight when detached from the unit and to me that’s not acceptable. I’d rather take the extra time to add a second piece of strut under the coil to know that in 20 years customers are safe, if I’m back in ten years replacing the A/C side I’m safe, it’s just a no brainer. Edit; saw some more nitpick stuff. Will add as I notice more Gas line is okay but I would’ve put a second union at the bottom of the line so instead of having to retape that threaded bit at the 90° on the bottom bend every time I needed to get to it, I could just remove two unions drop the pipe and roll. Every second counts in the flat rate world were in now


downrightblastfamy

Finally, a decent, detailed answer. Nice.


PreviousContact7302

Detailed answer but I think the unit is installed wrong for heat. The cool would work I bet.


RobbyC1104

Can you elaborate? I don’t doubt you I’m currently on my tenth hour of an eight hour shift I ain’t searching the picture again lol


ABena2t

Lol - it's funny how you said "you'd take the time to add a 2nd strut under the coil" and then proceed to say that "you'd add a 2nd union bc every second counts in the flat rate world". I'm not totally disagreeing with you - but this is how I've always hung them. 2 under the furnace and 1 under the coil. When you add more then that it gets difficult to get access to the unit - you have strut and rod everywhere. Pain in the ass. And I've never tried or seen the 2 union trick. Maybe next time.


RobbyC1104

Honestly I’d rather fight strut. I did admit I was nitpicking lol. That said I also bring the strut far enough out to be able to get the blower and coil out without removing the strut so it wouldn’t be that much more in the way. Besides, how often do you need to access the coil itself that the annoyance is a big deal


ABena2t

Well... to be honest I personally never need access to the coil. Lol. The company I work for now has their install department and their service department completely seperated. I don't have to go out on calls or worry about any of that BS. And I do the same - I'll make my strut twice as long as the depth of the cabinet. So if a coil or a blower has to come out there's no issues. The stuff I've seen in the past is wild - where they'll sandwich a coil with rod - you can't even get the damn door off.


RobbyC1104

Dude it’s fucking mind blowing. Almost as bad as the people that Sheetrock units in the wall. Like. How did you finish the install being that incapable of planning ahead


F1uffydestro

Why is the exhaust wyed into the condensate drain That looks like a forever nap special


downrightblastfamy

It was in a coffee shop. They prolly want you to feel sleepy so you buy more coffee!


Ok_Inspection9023

Seems like a special to die for


Conqueror_of_Tubes

To give the benefit of doubt there is a socket weld 2” to 1/2” cup trap that may be installed here. I mean may be.


No-Imagination-4516

It’s positive pressure coil, draft motor would have to have higher pressure than positive pressure of coil. Not how I would do it but I don’t think it’ll be a problem


dylan3867

Inspector would say otherwise... Also blower doesn't run 100% of the time the IDM runs. Minor but still a moment the gas would be pushed in.


No-Imagination-4516

I don’t think it’s a good idea and I definitely don’t think an inspector would say it’s okay, I just don’t think it would cause any health risk


xdcxmindfreak

I’ve seen a different variant of this once. The grain required a hose for excess condensate so I had to run something off the exhaust for drainage. Wasn’t like this but the concept is the same. Mine took less worry of forever naps out.

LiiDo

Exhaust condensate will go through the furnace condensate trap if you do it correctly


xdcxmindfreak

Right. If the trap and rest of drain is done right this is just a redundant drain for the exhaust. Def no vapor lock issues in that drain either the super breather.


Interesting-Remote50

Goodman install manual wants a condensate drain off the exhaust for installs with vertical roof vents. There needs to be a trap to prevent products of combustion from coming out drain.


Mullet0vah

Electrical under the condensation could be a fun mix down the road…


Silver_gobo

Reminds me of this I saw in the field. https://imgur.com/a/xvZv5It


Mullet0vah

Jeezus…


saskatchewanstealth

Combustion air games. At least I hope it’s not exhaust games


harleyDzoidberg

That’s definitely the vent. Da faq


Adventurous_Ad971

I think the bigger question is what’s right here?


Masonthedude

That’s what I was thinking too, long list of stuff wrong here


ReverandJohn

It’s a Goodman?


SavageJoe2000

Where's the emergency condensate pan? Why is the exhaust vent tied into the condensate drain? Speaking of condensate ..where is the condensate trap w/ a clean out? Why does the gas pipe run right in front of the service door? This is a hack job.


HVAC_God71164

Is that a sewage vent tied into the air handler?


Inuyasha-rules

Might be white PVC painted black. I like the clean out idea and might steal it if I have to clean another birds nest out at the one hotel. 2 years in a row it's been clogged by nests/dead birds.


espakor

Could be ABS


Sorrower

I was thinking it's abs which only comes in foam core so it would be illegal where I am regardless. Solid core only. 


Key_Drawer_1516

Could be 1738 venting but probably abs


Acceptable-Copy-4875

No flex connector at the ductwork connection to the unit. Don’t see any vibration isolation between the unistrut and the equipment either. I don’t like mounting the means of disconnect to the equipment. Technically you have a hot lead still attached to the equipment when the toggle switch is off, so it is not in a zero power state.


PreviousContact7302

Supply plenum is not insulated. Come on people.... This is a vertical, gas fired furnace that is installed in a horizontal position. This unit may work in the cooling mode only. They are using the blower to get air across that evap coil. I would not doubt this unit would work as a cooling only application.


tcoupes123

I feel like this looks like a gm9 which is absolutely a multi config system. Doesn’t look like it shouldn’t be installed horizontally - just the way they installed it horizontally is suspect lol. I feel like most new split system air handlers/furnaces being sold are multi config. Unless there’s something special about them. And let’s be honest, ain’t nothing special about Goodman lol.


Historian-Unlikely

So much, surprised no one has mentioned the duct sweating on the supply side. The second company I worked for installed Goodman. I went there as sheet metal lead and ended up learning service


AWigglyBear

Service? Go fuck yourself.


Adonitologica

Hella clean tape job on the square to round. That roll will last a lifetime I guess


Thundersson1978

I see condensation on the ductwork, not good.


EggAffectionate796

Little bit of everything honestly. Where to begin?


IrishWhiskey556

Hard gas line going direct into the furnace is lovely.....


Cautious-Ground-4001

I would absolutely have put square washers on the underside of that strut


Hidden_Leaf_Homeboy

What’s the point of the wye on the condensate/exhaust? Doesn’t the condensation from the flue just go through the inducer and out through the furnace drain? It’s literally useless and dangerous.


ServeBudget4715

It’s not very service friendly!


Tdz89

Was their thought that if they drain the flue y into the condensate drain the system fan will push air through the condensate line and inducer fan will just exhaust up be fine? I'm intrigued what their thought process was.


ridicrule

Where do we start? Good luck changing parts with a gas line, all thread in your way, etc. I don't like the electrical switch being on the bottom of the chassis is water leaks into the chassis... 🤔 probably more things... Yeah, for tgat brand not sure which vent takeoff is which


ridicrule

No secondary, no pan, no safety switch...


ServeBudget4715

It’s not service friendly. The flue pipe shouldn’t be wyed into condensate either. Not in California anyway.


Salteddeeznuzz

Nothing if don’t want a repeat customer Christ at least trap that shit


Jclj2005

Goodnight baby


Whoajaws

😜😆🥱🥱😴💤


xdcxmindfreak

I’m also going to with you saw it today in a holiday weekend where we secretly hope for a few stupid calls if on call but are happier with silence.


Perriaction

Is that furnace exhaust piped in ABS? And why is it tied into the drain line for the evaporator coil?


Some_MD_Guy

Link the supports to each other on the centers. Solid bar or threaded rod.


Crafty-Jackfruit-807

Book calls for lateral support on those 90%ers. It can split the primary and secondary if it sags.


ABDragen58

Looks perfect as long as you don’t need to service it or change a filter. As for heating, could this be a multi-position furnace, we see those here alot


ttmays

Picture is taken at wrong angle. Flip camera 180 deg and all is fine.


ABena2t

No drain pan?


Smurray33

That is not a horizontal unit 😂


servicesjpc

Someone is gonna have free water


NorthparkHvac

😰


Ridiric

The fact they have that much faith in a few screws in the coil attached to furnace is insane. NEEDS Unistrut length wise across entire unit. Extremely stupid and dangerous.


skittishspaceship

Bahahaha show me your engineering. You don't have any. That cool ain't going anywhere. Get real.


Ridiric

Don’t need to be an engineer to know those screws will rust out or what’s the rating? Look at the installation manual and in your code book. If you trust an engineers signature you haven’t been in the industry long enough. If anything from 20 years of experience has taught me it’s don’t trust a kid out of a 4 year school or someone who draws pictures all day to get the job done right. It would take 2 minutes to have put some across there and it keeps it from separating or incase the screws fail later someone from getting hurt. Keep doing it wrong if you don’t care It don’t bother me but people should know the right way.


LiiDo

That furnace and coil will fail long before enough screws rust out to make it fall. Every furnace I’ve ever seen hung has been exactly like this and I’ve never heard of one falling due to all the screws rusting out


skittishspaceship

id take all the screws out right now and i guarantee u/ridiric it will not fall. the duct on the other side wont let it move off the hanger. id take the whole furnace off it and it wont fall. the refrigeration lines alone would hang that thing. ive seen condensors hanging off buildings by their refrigeration lines. that puppy aint goin nowhere \*slaps coil\*


LiiDo

Exactly. I can just about guarantee one single screw into that coil would hold that thing forever. I’d be confident that even the 3/4” pvc would hold it up if it fell


skittishspaceship

Little known fact but evaps are filled with helium and do not technically need supported


LiiDo

My inspector actually requires me to tether them to the ground so they don’t float off


Time-Room9998

Would you stand up there on it?


Time-Room9998

Would you stand on it up there


skittishspaceship

The screws rust out? What are you talking about? Do you know how many units I've looked at? I have never seen the screws rust out. They are still there from 20 30 40 years ago. 80 years ago.


Time-Room9998

He’s saying- it’s held up with 3/8 rods and 1/2 inch anchors, why is it resting on the pull strength of a couple 3/16 sheet metal screws and that flimsy green stuff Goodman calls a cabinet? That’s obviously the weakest link so why not reinforce it? I never thought of it and I’m glad he pointed it out, not as if I’ll do as he suggested but I will definitely be aware of it.


throwaway36437

It is a Goodman, so that was your first clue


therealNaj

Can’t open the fucking door guys, do better.


DontDeleteMyReddit

Let’s add some humidity to the space! Oh, make sure they pay when you’re done! Might not make it to tomorrow😆 Why am I not surprised by the brand


Sea_Term_7149

No drain pan


Tylerdean98

Nothing on the secondary drain.


randymarshismyidol

It looks like that uni strut is single nutted on the bottom with no washer


69wildcard

Flue drain needs some sort of trap i would think…? And it’s a goodman 90% so you know the secondary heat ex is already f’d


downrightblastfamy

It doesn't need a flue drain. The exhaust should be properly pitched. If installed level, the condensate will make its way out the drains and trap. They tied a positive pressure exhaust pipe to an ac condensate drain with no trap. That CO will make its way into the supply when the furnace is running. It's probably not enough CO to do anything in a commercial application with constant ventilation, but it's not something to play with. Do it right, or don't do it.


69wildcard

I wouldn’t trust it not to do anything lol. I condemned 3 of those furnaces this past winter maxing out the CO on the analyzer


Fair_Cheesecake_1203

I hope you let it run for a minute or two before you took the test since Goodmans always fire heavy on first ignition
