This is really nice seeing a fix not caused by poor installation, repair or neglect. Also a fast in and out overall. I'm not a HVAC guy but I bet you wish more of your jobs are this simple, and clean work areas.
At one time I worked for a gas utility on high pressure gas transmission line metering equipment. Sometimes mud daubers would build a nest in a 1/4 needle valve. It would hold 400 PSI before giving away with a pow.
Thanks to videos like this I was able to fix my furnace. My induction blower vent line ran across the attic there was a slight dip in the line that caused condensation to pool and restricted venting. Thanks for what you do, these videos are invaluable!
Also, I thought I’d read in an American Standard install manual before that there needs to be a vertical piece coming directly off the furnace for a specified length before you turn. That 90 directly off the furnace could be problematic.
I greatly enjoy watching you but wow, the stuff you all go through out there! Here in California, just boring gas valves, pressure switches and noisy old people! Lol!
At least that guy didn't reuse B-vent as exhaust new new furnace.. I have seen that done. Condensate water dripping out of B-vent. Owner was not going to do anything about it since it worked fine for 5 years and he was going to sell the place anyway. LOL.
Instead of using tape. Which I don’t really like to see. Because sometimes the homeowner will get noisy and poke there fingers in to the furnace. Possibility of them getting hurt. So I use the end of a zip tie and press it into the door switch.
Don’t worry about the tape people. Sheesh 🙄. That’s a home owner anti tamper mechanism. Door switches are a nuisance to a technician, just something the government forces them to put on to protect stupid people.
But the question was did he remove the tape because he put the door back on while the boiler was still active so the tape was still on the switch it when he closed the door Why don't they use a dual flue system in usa so it's isolated completely, as that's how they do it here or most combi systems in eu/uk the pipe is double walled so the air that goes into the boiler comes from the outside goes into the boiler and then back out same pipe, at no point does any air from inside the building for efficiency reasons and no posable way to leak gas or burned gas into the room or roof space (as that can make them less efficient as it has to pull air from inside the building and get the issue like from portable ac units that pull are from inside the building) and you don't have a random pipe that just sticking out your wall that has nothing on the end of it to stop birds or objects from getting into it as there is a fitting on the end of the pipe
lee x code should require a screen on the end. I have seen more bad installations on this channel ( by others not this guy) than any where else. From talking to people I realized some states do not require a permit to change out the HVAC equipment. I do not want the government in my business but anyone who installs a gas furnace water heater etc should have it inspected by a second set of eyes if no inspection is required. Gas can kill you people die every year from faulty equipment and faulty installations. This should have had a double wall pipe that was the flue and combustion air all in one with the “T” connection at the furnace. I would not have left this job without giving a written quote on replacing the flue and combustion air. And saying in writing that it was not safe to operate and was not installed correctly. I also would have called the company that did the installation and explained what I found to the qualifier before leaving the home. If a permit was required I would also call the building Dept and report it to them as well. You do not take even the smallest chance with someone’s life. I’m sure I may be over reacting and it would work fine for years as is. but what if..........?
You are pragmatic about some things like I am. I see something like that old vent pipe and chuckle while taking a picture of it to share, but meh, it ain't hurting anything.
How did that furnace install get a pass from the fire Dept inspector? No primer no epoxy and not even seal at the exhaust pretty of the inducer motor. WOW!
The other thing I was surprised about was how easily the pvc exhaust came apart we were always told to use primer to marry the pipe for bonding otherwise you could kill a family another tech said he never uses primer on exhaust because there's no load he said but i beg to differ
Had a couple of dead mice in a nest they made in the pipe once. Also had a 5 gallon bucket full of acorns a squirrel had packed in the pipe. Good times.
There is about 18” of pipe from the inducer to the outlet, it’s perfectly fine. If the inducer exited right at the street elbow it could be an issue, but in this case it’ll never cause a problem
I think you need to go back and check the pressures again. I have found that if you check across the pressure issue is cause by a failing secondary. If it isn't .4"-.6" higher then what the switch is rated for the secondary is failing. Please check it out
Mr. Cook, Looks like a hornet nest. Thank you for all of your videos. I am a DIY person but I use caution and have experience. I watch your videos to see what not to do and to watch for. Thank you for what you do.
90 degree elbow right out of the gate, is a no go in my jurisdiction, my city inspector would personally fine me on the spot if I did that for wasting his time to book an inspection. Whoa, the US sure does things different.
Here we have enough common sense to go by the manufacturers specs.... we have no control freak over zealous pipe freaks like they do up North. So.... if our ways are so bad and dangerous, why have I seen and done all of this for well over 30 years without one single issue ?? As far as your "out of the gate" point of view... there is a straight piece of pipe about 20 inches long connected to the induced draft motor assy. inside the furnace. So exactly how much straight pipe do you and your "inspectors" require ? and why ? Does your building codes dept. think they know more than the manufacturer of the unit ?
Why dont you have a ladder with you ? Ive been in the trade for 20 years and i always had access to ladders on my truck. Its basically must have tool in my inventory. Anyway great series of video you have. Thanks
Love the video but umm if you pause it right on 9:29 you left the tape on the door switch and proceded to put the door back on without removing the tape.
Why would they cut it at a 45* instead of putting a 90* or a tee on the end? I have always done that but everyone is different. A tee would stop the rain but still flow, a 90* would stop birds or even detour the Hornets and bees. Whats your best method Ted? Thanks for the video
donovo “works fine,” it’s not even sitting over the hole... installers either didn’t care or were too lazy to run an extra PVC pipe. Probably another underpaid installer working for scraps, slaving away in another attic, I probably wouldnt have given a shit either if I were him
I would rather use the old vent as an intake then run anything new through your roof. Every time you open a new hole or mess with a non leaking hole there's a chance of issues.
The first thing I thought was a wasp nest. I’ve found dead wasps inside my inducer fan housing, making a huge racket. I hired a roofing contractor to inspect the flue pipe but he didn’t find any nests. I must have turned on the furnace right when the wasps were starting to build the nest and killed them. I guess a screen could be placed over the end of the pipe but that might restrict the flow too.
Good, very helpful video but... First off: 90 right out of the IDM exhaust pipe?? Really? Second: I know it helped you out this time around but you shouldn’t be able to pull the exhaust pipe apart. It should be pvc cemented even at the furnace. I’d be fired if I did that install.
In my 35 years of inspecting furnaces for the gas company I would like to have a quarter for everytime I found tape on the door switch. Almost Human great eye for catching that one.
This is really nice seeing a fix not caused by poor installation, repair or neglect. Also a fast in and out overall. I'm not a HVAC guy but I bet you wish more of your jobs are this simple, and clean work areas.
The furnace isn't installed correctly. The old flue should have been removed and new pvc run to the intake/combustion side.
Ted, I am so glad you have been posting more lately, thank you!!

This is why I watch all your videos you have the knowledge and take the time to diagnose the problems before throwing parts at it!
Also, I thought I’d read in an American Standard install manual before that there needs to be a vertical piece coming directly off the furnace for a specified length before you turn. That 90 directly off the furnace could be problematic.
Gotta love those bugs. Always finding creative places to nest.
Good catch on that one Theodore.👍👍🇨🇦
Love your videos..... I think you left the tape on the door switch. But the next service guy will be happy he doesn't have to go to the truck.
I greatly enjoy watching you but wow, the stuff you all go through out there! Here in California, just boring gas valves, pressure switches and noisy old people! Lol!
gosh. i hate those things . They always come back . maybe a screen would stop them.thanks for making this its very helpful.
Who did you get to install the pop up door on the outside of your Chevy express? That’s brilliant.
Needs to have a screen on the end of the pipe, last year I had a nest of yellow jackets get into my furnace B Vent
Whoever did that furnace install should lose their license
Nice job and video
At least that guy didn't reuse B-vent as exhaust new new furnace.. I have seen that done. Condensate water dripping out of B-vent. Owner was not going to do anything about it since it worked fine for 5 years and he was going to sell the place anyway. LOL.

Good find man
Gas hooked up with an appliance connector, really WTF
No glue on flue connections? No hangers? A galvanized intake? Who the hell installed that thing? The Three Stooges?
What's wrong with a galvanized intake?
No glue made his job easier.
You need that magnet thing that Steve Lav uses to hold down the door switch.
Wow who the hell installed that
God is Good! 🙏🏼❤️ Amen
Did you take the tape off the door switch when you closed up and left
Don’t worry about the tape people. Sheesh 🙄. That’s a home owner anti tamper mechanism. Door switches are a nuisance to a technician, just something the government forces them to put on to protect stupid people.
At least it wasn't another ON/OFF issue!! :-)
you left the tape on the door switch. lol
You forgot the tape, :) but still a good digenosis, need more vids out there like that
Really good find!! Nice job!
good video. how did it fire up with the door off? did you remove the tape on the door switch?
Eddie Sellers he tapped the switch basically the tape holding the switch down acted as a door holding the button down
But the question was did he remove the tape because he put the door back on while the boiler was still active so the tape was still on the switch it when he closed the door
Why don't they use a dual flue system in usa so it's isolated completely, as that's how they do it here or most combi systems in eu/uk
the pipe is double walled so the air that goes into the boiler comes from the outside goes into the boiler and then back out same pipe, at no point does any air from inside the building for efficiency reasons and no posable way to leak gas or burned gas into the room or roof space (as that can make them less efficient as it has to pull air from inside the building and get the issue like from portable ac units that pull are from inside the building) and you don't have a random pipe that just sticking out your wall that has nothing on the end of it to stop birds or objects from getting into it as there is a fitting on the end of the pipe

Great detective work 👍👍
Don't believe i ever saw double wall pipe used for combustion air. Or dirt dobers nest that far in a flue pipe.
They left the double wall from the old furnace being lazy, and I'm with you I would have never looked that far in
You are pragmatic about some things like I am. I see something like that old vent pipe and chuckle while taking a picture of it to share, but meh, it ain't hurting anything.
Glad you’re posting a lot lately man
How did that furnace install get a pass from the fire Dept inspector? No primer no epoxy and not even seal at the exhaust pretty of the inducer motor. WOW!
I hope you went back and pulled that tape on the interlock.
What about the tape on the door switch? Furnace was running when you put the door back on.
Did the mud dauper do that on purpose, I bet he did, wise guys
Oops did you leave tape on switch?
I lol’d at the thumbnail.
Nobody glues 90+ flues out there?
The other thing I was surprised about was how easily the pvc exhaust came apart we were always told to use primer to marry the pipe for bonding otherwise you could kill a family another tech said he never uses primer on exhaust because there's no load he said but i beg to differ

Pretty sure you need 12” rise before a 90 turn
There is about 18” of pipe from the inducer to the outlet, it’s perfectly fine. If the inducer exited right at the street elbow it could be an issue, but in this case it’ll never cause a problem
Good job. You even glued the pipe back together.
What do you call those down there , we call them muddy bees
I think you need to go back and check the pressures again. I have found that if you check across the pressure issue is cause by a failing secondary. If it isn't .4"-.6" higher then what the switch is rated for the secondary is failing. Please check it out
Sweet Jesus. 90% with a 4" flue on intake lol.
Do you have a red tag system? And get the customer to call the amateurs back that installed it to install it to code.
Nice awesome video.
Hi... Thanks for the video... I am not an HVAC guy however I had a no heat issue on the exact same model in the American standard label
No ladder rack on the truck but nice rims!
Mr. Cook,
Looks like a hornet nest. Thank you for all of your videos. I am a DIY person but I use caution and have experience. I watch your videos to see what not to do and to watch for. Thank you for what you do.
No, that does not look like a hornets nest. That is spray insulation.
I thought Nothing can stop a Trane...... 🤪
Start driving your bucket truck, then you wont need a ladder. :-)

what a crappy install!!!, good video tho. One question, you left the tape on the door switch didnt you?
Yes he did if you pause it just right at 9:29 he left the tape on the door switch. Tisk tisk
Mud Dauber Nest (wasps)
I was looking for this comment. At first I was like, what the hell is that? Then he turned it around and I thought Mud Dauber nest?
I reckon you should get a head mounted go pro for your videos :) free up both hands
You are not the first one to suggest something like that I've noticed in comments previously.
This locks fun
Why dont you have a ladder with you ?
Ive been in the trade for 20 years and i always had access to ladders on my truck. Its basically must have tool in my inventory. Anyway great series of video you have. Thanks
Love the video but umm if you pause it right on 9:29 you left the tape on the door switch and proceded to put the door back on without removing the tape.
My first thought was 😳🤭... still, at least disconnect the old sheetmetal pipe to the roof line.
That's a new one. I've had water get moving back and forth birds but never that
I know this was a long time ago but as you were closing up the door at the end it looked like the duct tape was still on the door switch.
Do you always just rely on the furnace control board LEDs or ever try to use a meter and order of operations lol?
Why would they cut it at a 45* instead of putting a 90* or a tee on the end? I have always done that but everyone is different. A tee would stop the rain but still flow, a 90* would stop birds or even detour the Hornets and bees. Whats your best method Ted? Thanks for the video
As a DIY-er I also put tape on the door switch while troubleshooting. But I always remove when I am finished. ;)
why did they leave that metal pipe as the fresh air intake???
Chris Scerbo
Why not? Works fine
donovo “works fine,” it’s not even sitting over the hole... installers either didn’t care or were too lazy to run an extra PVC pipe. Probably another underpaid installer working for scraps, slaving away in another attic, I probably wouldnt have given a shit either if I were him
I know. but for the most part in NJ we just dont do that.
I would rather use the old vent as an intake then run anything new through your roof. Every time you open a new hole or mess with a non leaking hole there's a chance of issues.
@@mikejones-ku5ix or you could just learn how to seal it properly...
2:00 gas flex though sidewall
Good little vid Ted ...
What about that piece of tape
U forgot to take the tape off the door switch....back to the attic 🤪
did you remember to take the tape off before putting the cover back.on?
I had A BUNCH OF BIRD NEST,PROPER SCREENED 45
Did that release carbon monoxide into the attic when disconnecting the pipe?
Matt Bruns the switch had pulled and the gas valve didnt open. There was no CO as combustion had not happened
@@oleksi9336
Ahh yea it was fired up but only for a bit as soon as he put the pipe back on it kicked out
Never took the tape off the safety switch for the door next guy that goes in might make a hack video on you. Just saying lol
The first thing I thought was a wasp nest. I’ve found dead wasps inside my inducer fan housing, making a huge racket. I hired a roofing contractor to inspect the flue pipe but he didn’t find any nests. I must have turned on the furnace right when the wasps were starting to build the nest and killed them.
I guess a screen could be placed over the end of the pipe but that might restrict the flow too.
This goes as a lesson that pipe diameter is important installation
Good, very helpful video but...
First off: 90 right out of the IDM exhaust pipe?? Really?
Second: I know it helped you out this time around but you shouldn’t be able to pull the exhaust pipe apart. It should be pvc cemented even at the furnace.
I’d be fired if I did that install.
You are incorrect sir ... read the installation instructions ... all furnaces are not the same. Thank You for watching !!
@@TedCookHVAC I believe it required silicone rtv
So continue watching!
What camera you shooting with?
audio superlow?
now u get to charge $3000 for the fix!!
nice souvenir!
Those are Mud Dauber wasp larvae
Do believe he didnt remove the tape lol.
No beuno, safety hazard for the homeowner.
Maybe he used to work on stuff at Watergate.
Damn, could've got stung to beat hell! Interesting find for sure.
mud daubers are very non-aggressive and generally avoid stinging anything.....
What was the reading after the nest was removed? Just curious
Same as when the flue was pulled out if the furnace......
You left the tape on the door switch.
In my 35 years of inspecting furnaces for the gas company I would like to have a quarter for everytime I found tape on the door switch. Almost Human great eye for catching that one.
What did you pull out of the flue exactly
Another gas valve off? Nope.
Good find. But y no Glue on the coupling
Run when you see that plastic fitting that runs into heat exchanger, they break and your fucked, worst thing ever
Manometer do doo do do doo manometer do doo do do manometer
The previous install forget to install a screen on the exhaust but it’s a very minor mistake.
After a critter got in mine I bought some rat wire an caged in my pipe
Forgot the tape on the door switch just fyi
Why would you go up into an attic on a no heat and not take a manometer and a DMM.
good one !
Noticed that green ontop.of the furnace under condensate line. Either not fully insulated or drain pan issues.
