The best video on the topic. Everyone who buys the house needs to view it at least once in his short life. Greetings from Pakistan.
As a student I was struggling in learning this trade in school. when i watched your videos everything I didn't understand made sense to me right away. I really appreciate you putting these videos and the quality of information you have in them. I can't thank you enough!
Yea i just got into this trade and he made hours of studying and hard to understand so simple to me less then 20 minutes lol
I’m in HVAC school right did u guys get taught the Bible too?
Very eazy to understand
Electricians have the easiest job
Wow! You explained everything in plain English that a non-HVAC person can understand. Thank you!
Hi jay , I really regret wasting my time & money for attending an HVAC school , because I learned a lot from you & some other Techno geeks & applied it in my job .
Because of the knowledge I got from you & others like you , now my employers think I invented HVAC system . Isn't that amazing
Jay , I wish you healthy long life to help fellow tradesmen like me .
just signed up for HVAC school
started watching his videos to get a better understanding
I feel very confident and comfortable about going
thanks brother
You would be gobsmacked to know just how many "schools" exist solely to abuse pell grants. I almost went to one of these holes out of high school- thank goodness I avoided it - place set off my radar for whatever reason and just felt wrong. I worked with one of these institutional victims years ago, calling himself a "tech" - the dude could NOT read prints... which also meant he could not perform many specific isolations except someone else wrote a procedure for him. Supervisor kept him around only on account of there was enough mundane stuff with written procedures [or simple devices] it freed up time for others that were capable of troubleshooting the complex.
@@troyquintanilla5418 videos are paid or you are talking about UA-cam videos?
Finally a decent video on gas fired furnaces. Learned more than the last 15 I watched.
I've watched every furnace video out there and this is by far the most concise. Presentation and production value top notch.
Thank you! :)
This video should be a must see for all forced air furnace owners & users. At the very least, they would now know when it's necessary to call a professional. Thank you for this video, very much appreciated.
Thanks Tom! Glad you liked the video!
You don't know how annoying it is when you call us and it was the switch on junction box that was flipped. We all get annoyed. Mostly customers. They get mad and usually don't want to pay our service fee.
@@christianruvalcaba7788 They brought you there; you spent time and money; they must pay for service call. You should perform an inspections while there so they won't feel bad. In areas like here in Houston where furnaces are in the attic, sometimes a plumber or electrician flips the switch to off by mistake and never resets it.
of all the furnace related video's your's is the most thorough and informative - Thank You !!
Thanks Ken!
@@WordofAdviceTV ko
I am pissed off
As a retired HVAC tech I found this to be a very good video. The only thing I want to add is that a cracked or leaking heat exchanger can cause the rollout switch to trip and the burner/manifold system is actually designed to pull in a lot of air(called primary air] Which mixes with the gas so it has enough oxygen to burn efficiently with a basically blue, soot free carbon monoxide free flame with exhaust gasses that are basically composed of carbon dioxide and water vapor.
I disagree about the exhaust gases. It is carbon monoxide and water vapor. Carbon dioxide only comes from animals including humans when they exhale during breathing.
@@davidm7824 You need to do some research because you are mistaken. Natural gas is the cleanest burning of all fossil fuels under the right conditions. These conditions are a proper air to fuel mix (called a stoichiometric mix) which results in what is called a complete combustion which means there is not any excess fuel or excess air in the mix. This results in a blue flame with combustion products of mainly CO2 and water. A rich combustion mix, meaning there is excess fuel and not enough air, results in incomplete combustion with a yellow flame full of soot and carbon monoxide. I have personally seen and been exposed to both these types of combustion products. Look it up.
As an instructor in this field. Myself and my staff show your videos often. Now that we are online format we really enjoy having your videos as a good to.
It's an honor! Glad to hear that my videos qualify to be shown by instructors :) Thank you!
I'm starting a Gas Furnace Troubleshooting and Repair training class in a week, and trying to study up before it begins so I'm not completely clueless on the first day.
Your videos have been so informative and easy to understand. You have a gift for teaching! Thank you for helping me get ready to dive into HVAC
Teaching really is a gift, if I had to ride along with this guy it would be an honor.
This video and you're 10 most common problems are 2 of the best videos on this topic I've ever come across. I'm in school for my gas 3 license right now, you're videos teach just as much if not more than my entire cirriculum
Man your good. How old is that furnace? It is the cleanest one I've seen. I trying to learn how to troubleshoot and maintain my home furnace and your videos are very thorough. Thanks for putting this together.
I go to school at RSI in Phoenix Arizona, and your videos helped me pass Phase 6 which focuses on comfort systems. Your channel is the best thing ive ever found.
Glad to hear that Adam! Thanks! Good luck with school!
Hey Adam, reach out! So did I and I continue to watch his wisdom here!
Did u graduate. I'm in school now and am curious how you are doing now
Career wise
you know this video i dont like it .......I LOVE IT!!!! BEST EXPLANATION EVER....
Hahaha that comment had the desired effect :) I was already guessing what exactly you didn't like. Glad you loved the video! Thank you for watching and leaving a comment!
I replaced my entire HVAC system last December and put in a Trane variable speed system. Best choice ever. My electric bills went down. Also, for the most part, my house feels comfortable all day long. Additionally, I don’t hear my unit turning on and off all day. I would highly recommend spending the extra few bucks and go with a variable speed system if at all possible.
The capicator helps start the blower by causing a phase shift in one of the field windings of the motor.
Great video hands down the best. Quality of video, description, narrative top shelf
Thank you
This video is the most helpful video I have found yet. I just started a job as an HVAC Maintenance tech with zero experience and zero school. I just started my 2nd week of training and really trying to put in the work to thrive in this field.
NEED VALVE FOR 1976PROPANE warm morning spaceheater
my gas furnace is trane and has an issue that all time never go up two degrees, will shut off, if the house temp 69 and i set the thermostat for 71, it's going to shut off soon reach 70, three techs came and done nothing, the control board has no light indicator to show you the error!!
please advice.
I always review you previous video particularly furnace or all off them, very direct tutorial. Specialy i dont have that much knowlegde about furnace,here we called that AHU.thanks alot
I like how he doesn’t go fast and how he explains it so you can understand it. If it seems confusing it’s because the topic is new to you.
We just got some snow the past few days and my furnace is having issues so here I am haha. You are great at teaching the names of all the parts, and your explanation of how furnaces work is very easy to understand. Great video quality too, very clear and easy to see everything. I had no idea what any of the parts inside were but now I have a much better understanding. I've got a 90% furnace and it started leaking a fair amount of water right around when the temperatures got below freezing outside and we got a few inches of snow, because like you said, there's condensation in the second exchanger. Seeing a lot of rust where the inducer connects to the PVC pipe, right around the clamp ring as well, from your explanations though it doesn't seem like that pipe should be seeing that much moisture though.
90 percent furnaces should be taken apart and the inducer motor rinsed out once a year before heating season. The white condensate trap box taken and also rinsed out. Maintenance is always needed every year. Heating and cooling season.
Hi, I never ever left any comments on UA-cam,
And because of how you go through every details on your videos. So for that I would say you are the best
I learned more in this one video than I did in college. Thank you so much.
Thanks Kenny! Glad you liked the video! :)
Kenny R duuuude same here!
that's so true I learn alot from here also I share his video to my family and friends.
@@joeyxu5887 Good to hear the videos are helpful! Thanks for sharing! :)
Yea man.... in college, the professors/ instructors go too technical and not enough hands on. Or sometimes they just get real impatient, and call things by some weird name, without explaining it.
Appreciate all the info you have posted has helped me diagnose my furnace over the past week to find it was my air pressure valve switch.
I’m a new home inspector and HVAC is one of my weaknesses. This was a very informative video. You did an amazing job describing the parts of the system and how they work. I’ve subscribed and I hope you have a similar video for the A/C unit. By the way, I notice there is a gas union inside of the unit. I was taught that should not be inside because it is susceptible to leaking. Great job.
Every gas furnace has a union line inside

One of the best 15 minute educational videos I've ever watched. I appreciate you taking the time!
Thank you! :) Glad you found it useful!
My Furnace troubleshooting :
Vulcan Product no 5300052 and Serial no 00447836,
Previous Problem / Initial Problem
Furnace didn’t want to start if the Room Temperature is below 16 or 17 Celsius degrees.
If already starts, no problem.
I try to learn troubleshooting from UA-cam.
So I know about FURNACE FLAME 🔥 SENSOR and IGNITER. And also know about the CAPACITOR.
I did change the FURNACE FLAME 🔥 SENSOR and IGNITER, and also the CAPACITOR.
The Furnace when one day already ON ( it could ON, when the Room Temperature is gonna up from 16 C to up ), all the day we have no problem. Because the Room temperature is still about 17 C or higher.
The Problem of my Furnace is only:
It couldn’t ON on a day when the Room Temperature is below 16 C.
That’s the Problem!
Hi 👋 J, could you advice me, what part should I change again ? 🙏
Nice presentation, clear explanations, easy to follow with out any stupid music or exaggerated enunciations! Thank you! Also since you asked, you forgot to mention the step down transformer attached to the external metal junction/switch box. Perhaps its for AC contactor or thermostat? 😉👍
Thank you for pointing that out! That transformer is for my whole house humidifier.
Good explanation of the basic parts. LOL on Amish joke. Anyway, you didn't mention the big transformer mounted to the junction box, but mentioned a little box by the control board as the transformer. I am familiar with the big iron transformers like on the junction box, but the little plastic box....Is that really a power transformer? Is part of it hidden inside the steel enclosure then? If so, was the bigger one outside added for the AC system?
Amazing explanation, just amazing, it is so thoroughly and simply explained that a person like me who is interested in becoming an HVACR technician will know it all. Thanks for making such videos.
Amazing video this is really gonna help when I start school the 1st🙏😁
Glad it helped! Good luck in school!! If you're already watching videos like this, you'll have a nice head start!
Great video with good lighting and crystal clear explanations. My work often involves LP mobile home furnaces of about 57K BTUs utilizing old school pilot light ignition and the occasional HSI + combustion blower, but no draft inducer such as these residential units. This was enlightening. 👍👍 Thank You!
Tstat calls for heat
Inducer motor
Pressure switch
Hsi
Gas valve
Flame sensor detects combustion
Hsi turns off
Blower
Tstat gets satisfied
Turns burners off and fan blows until unit cools off.
Fairly simple... Well kinda lol
so what would you advise if i changed the ignitor and sensor and my furnace still doesn't fire up. Seems like no gas is coming out. Ignitor glows but then shuts back off. Like i mentioned both are new and have been replaced. (ignitor and sensor) old Ultra V enhanced 80 furnace
Great time to watch this before winter starts , thanks again , hope you make videos on pulling vacuum and replacing a evaporator coil
Lol, you forgot about the taped door switch! And the dangling 3 amp fuse. But great video though! Keep em coming!
Ack! I cant believe I forgot to talk about the door switch! Thank you for pointing that out. The door switch is like a secondary power switch that shuts off the power to the furnace when the bottom door is taken off. I taped my door switch so that I can check voltages on the board and so that my furnace does not shut off when I take the bottom door off.
About the 24v fuse. My control board does not come with a place to plug in the 3 amp fuse so I just spliced it into my 24v hot wire coming from my transformer. That way if there is an electrical short at some point, it will burn out the fuse instead of my control board.
Jake, I know you probably already knew all that, I explained for others who may read this later :)
I have left my door switch taped like yours for a couple of years. Does not hurt anything and is helpful when checking out electrical issues.
@@briancloutier2781 Yep. That's my thoughts on that too :) The door switch is a safety feature to protect not-so-careful homeowners from getting zapped if they venture into their furnace.
The invincible printer aerobically shave because box seemingly bat unto a jaded wind. waiting, painstaking square
CREDIT GIVEN WHERE CDEDIT IS DO ! GOOD JOB on your videos ! As a Master Plumber for 40 years its REFRESHING to finally hear someone EXPLAIN CORRECTLY your HOW TO videos ! GOOD JOB !!
Thank you! Means a lot coming from someone whose experience alone is older than me heheh :)
very nice, had my furnace acting up today, the fix: took a gem clip and cleaned out the holes in the orifices. 2 of them were lighting the third on the end was clogged and not firing so it was immediately shutting down on ignition, working fine now.
Would've been nice to not be interrupted with ads every 2 minutes, but no.
Thank God I can use Ad Block whenever I want.
Otherwise, pretty good information.
Nice video, my old Lennox pulse had the control board in the same place and over time the board formed a hair line crack in it due to it being in this location as the blower motor vibrations over time caused this to happen, the furnace would come on and then cut out and wasn't operating properly, it's a bad Location for the board as my old one was not repairable the new one was $900.00 and I made sure to relocate it in an area of no vibration as this was a bad design of the furnace manufacturer. Thanks for the information and good luck.
i have a Lennox 9ougfa3-75-6....its 19 yrs old. Decided to remove the blower at the bottom and clean it out. i removed the control board first, and set it aside but there were so many wires i had to cut the plastic harness on them so i would have room to remove the blower ... I put the control board to the outside and removed the blower. It was very dirty and i cleaned it out without removing the motor off it .I wanted to remove the motor and started to to along with the ground wire but put it all back when i realized that wasnt a good idea.
put everything back, and started to remove any black tubing i could clean out and came across a black tube with a small nail like hole at the end of it attached to what i think is a o pressure switch..put everything back and the unit sounds like its going to start but then nothing happens. No diagnostic lights come on either , any idea of what i may have done? Is there a wrong way to reattach the ground wire lol ?
I have the exact Same a.c. heater furnace as you do but mine the heater will not turnon. I cleaned the flame sensor and my inducer motor turns on briefly when i touch the flame sensor.When I place a jumper on R and W1 nothing happens.
That was very informative and funny! Talking about the Amish washer!!! 😂
Thanks for taking the time to do this. Great production and explanation. Have watched a few of your videos and all are really good.
Hey. Genuineness. Take the tape off your blower door switch. You make a vedio about what the what the parts in the furnace are called and the safety of the components and you leave the tape on your blower door switch.
You rock brotha 👍🏽👍🏽👍🏽thank you, keep working on your jokes though 🤣🤣
Excellent vedio presentation with details of furnace components. I never have any clue what is inside furnace. Very v
Awesome video.100% well done.
Love your work.
Thanks so much....
Amazing channel awesome and informative , you motivated me to. Start my channel and share what I know as well , keep great work up 🙏🙏
You are awesome! I wish you were located in Virginia because I would recommend you to all my clients.
I like all you said very informative, I also like Umesh washer and dryer, God Bless You.
I now know more about how a furnace works than I ever needed to or wanted to. Great video though, I’ve always been fascinated by how things work.
Excellent overview. Thank you for sharing your knowledge. Much appreciated.
My furnace make a puff , or whooping sound , if your watching it , you can see the cover actually puff , or flex , like a pre ignition issue , not sure , I will clean the flame sensor , and burners , then re observe.
hello nice video i am interested to ask you about the axulirary switch on blower housing, anything you know about it?
Thank you so much for your amazing explain how the furnace working .. i need to know my friend the filter in return aur in roofing furnace is the same one in stand furnace or there is another one .. Thank you
Thank you I was able to find a resettable switch that was the problem. (I cleared out the dead bugs that were in the burner area).
you missed the door switch.
You have outdone yourself with a great video, man I left a like and also subscribed, very well explanatory
great video simple explanation i am going school to get my hvac license ,,,,,it will help me when i will reach this topic.
This video is a lifesaver you’ve blessed many techs out there I’m sure 👍🏾
What about the temperature switch(s) for the blower control, when to start blower, when to turn off blower.
This vid should be tutorial for making instructional vids. A+
you know how to speak english. that's what i'm talking about not so technical yet very easy to understand how it works, very very great video 5 star!
You are the GOAT of HVAC
Thank you for making this video, it would've helped me a lot when I was at school. My teacher made it more confusing than it actually is and I think it's much easier and faster to learn this stuff by seeing it than reading of reading about it in a book. You're the only person that makes decent videos related to HVAC. I get really tired of the old guys in the trades upload videos in 240p and try to teach us this stuff.
Those older guys know much more than I do, that's why I try to stick to the basics :) But yes, I agree! Good quality videos is a nice bonus! Once again, thanks for watching and commenting!
I really your videos.
Thanks.
Keep up the good job.
I have a question. My furnace room and inside the furnace is very dusty. Is that gonna destroy my furnace? what would you suggest me to do? Thanks
Well, you can try vacuuming out what you can. It won't destroy the furnace but it may take out the blower motor. If you want, you can watch how dirty mine was when I replaced the blower motor on my furnace. (the one in this video) Just look up my video on blower motor replacement.
i was tring to figure out how the furnace water drain worked, but good video, I learned a lot
Bratan, u tebya russkiy akcent vmeste s Minnesotskim akcentom. Kruto!
i learned more important info in 15 minutes in this video than the last 3 months of HVAC school
Great video. :) The biggest mistake you-tubers make is poor video production (flashing from scene to scene). You do a great job. This is not like my system but it is very interesting to watch! Thanks. Ps. There is a mechanic out on you-tube .... South Main Auto. Another guy who knows how to make a video.
Thanks Viking! I watched a couple of his videos and yeah, he makes it a point to make sure the audience clearly sees what he is talking about :) That's always nice. Kudos to him! My wife films me but him, it looks like he does it all himself, with a tripod. Must take him a while to make those videos.
Everybody knows that they’re called thingymcbobs
THE BEST VIDEO IN MY OPINION, l liked and subscribed
what’s the pipe that leads outside? mines is a white pvc pipe and whatever it’s connected to makes a whine noise
You probably offended the Amish. You should make another video to apologize to them.
Just kidding, in what state are you?
Im an electrician and want to learn this stuff. Because It seems i have a lot of hvac problems in my house, wasting money. I should just go through the program and learn how the systems works, so I can fix it myself.
I know some Amish people and from what I can tell, they can take a joke ;) I am from Minnesota. And yeah! If you are an electrician, you will already know a lot of the basics :)
@@WordofAdviceTV the amish would probably never see the video anyway
@@sglacf Lol, that's a good point too
Your videos are very informative! Thank you for sharing your knowledge.
Very well done. Thank you. Also learned what an Amish washer and dryer is. lol
My furnace rheem 30 years old yesterday stop working 😔😔😔
IT INTERESTING YOUR CLASS, TANKS GUY.- FROM CHICAGO IL.
I learn more through your videos than what I did while in trade school..
Thanks Eric! Glad to hear my videos are helpful! :)
when are you planning on doing a avideo laying out all parts of an electric furnace?
Best furnace troubleshooting video on UA-cam - Thanks!
Your videos are excellent and thorough! Very clear; voice and commentary helpful; showing the part/cause and effect very helpful. Helped us diagnose dirty flame sensor and then a bad blower motor.I now know more than ever thought I would on furnace operation and diagnosis. Congrats!
I have a propane furnace I switch from a big tank to a small barbecue that will tha cause not to start?
In a high efficiency furnace (2 pvc pipes) is the combustion process completely sealed and separated from the air that mixes into the home? I ask because a new Radon mitigation install has the outflow pipe outside the home within a couple feet of the intake pipe to the furnace.
I stuck coal and raw chicken in my furnace and it didn’t cook I wonder why
PLASE PLASE PLASE is the gasket from the inducer more asbestos?? Iv remove mine and it was falling apart, lost of little airborne fibers.
I am pretty sure what you are talking about is fiberglass so nothing to worry about. 👍 As far as I know, no furnace gaskets have asbestos.
Can't see what he's pointing at the screen is too small from original video
came to learn the furnace components... stayed for the amish joke
I can see why you don't have to have a regular job anymore and can live off making these videos. Your videos are my go to for pretty much all HVAC questions.
Thanks for the video!
Thank you again
I will not join any online school to learn HVAC
I can see myself to learn from you.
I do practically work with installer twice a week.
Great video, I think you should start teaching.
You are the best 🙏🙏🙏🙏🙏🙏🙏
A union on the gas line, inside the furnace cabinet is also not recommended and many states not code.
It used to be common years ago but the codes have changed in many places. I saw that too ;-)
