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.
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!
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.
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.
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.
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.
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.
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
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
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
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!
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.
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
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
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..........?
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.
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 ?
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.
I suppose that is not a horrible idea for air intake, so as long as they lined it all up nicely. What's the deal with the PVC junction at the furnace discharge being so loose? Is that usual?
