I was in the hvac field for 7 years and have been in the transportation field for 18 years. Your videos are the best! They help me refresh every winter. Wish you were around when I went to hvac school. It wouldn’t have been so helpful. Please, keep up the great work!
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!
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 .

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.
Thanks to you I was able to diagnose failed igniter and replaced and now furnace working great saving me minimum 600 repair with labor.Cost me 50dollars for igniter! 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.
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.
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.
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.
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.
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.
hi everyone. I am handyman and always follow this young gentleman here . he is is good briefly explain everything. also understand able. thanks him with best wishes
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
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.
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 !!
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
Hey bro I really appreciate how u speak and explain everything very slowly so a new guy can absorb what ur teaching . Please keep putting out or refer me as a new guy to basic info that will help me get my foot in the door to an havc co . Thanks
You are a very good teacher; pronunciation, tone, and simple language used, even a person like me whose first language is not English can very well understand.
Hi, I never ever left any comments on RUclips, And because of how you go through every details on your videos. So for that I would say you are the best
Your videos are fantastic. Thank you. I have learned a lot from the wisdom you share. I am not in HVAC, but I really wanted to learn as much about AC and heating as possible, particularly since I live in a hot part of AZ. You are thorough, yet to-the-point. It is evident you are passionate about your trade, and it shows that you are an expert in your field. Thanks for making these for us.
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!
Had furnace issues. Went through all of your checks. Narrowed it down to the gas valve or the control board. Ended calling in help. It was the board. I’d hesitate to call them pros , they just replaced both parts , till it started. . Great videos . For others, My symptoms were the igniter would heat up. The fans would run, but No gas would come out at all , and it would just blow cold air.
Thank you for the detailed explanation. I am having a problem with my furnace now. With the help of your videos, I know what to check and fix the problem. Really appreciate it.
You’re the man bro I started a hvac apprenticeship and I really love the job and can see myself doing it for a long time but I was having trouble understanding some things your videos really help so thank you
Hey Man! I've removed and cleaned my flame sensor on my York furnace previously. It was more good luck than good management that it worked. I just watched your series and wish I had before. Complete and understandable explanation. I'm much the wiser and thankful. Anybody with a gas furnace should watch these. Much appreciated!👍
Thanks, I've been tinkering for over a year; flame sensor is good, high limit switch is good, hot surface ignitor is good, new nest t-stat upgraded/good. Still experiencing intermittent heat! This video helped me check the flame blow back sensor; luckily it had a manual reset option! My Wife is happy again 🤩👊🏾🎉🙏🏾
Terrific video explaining a gas furnace and its components - well done! Our Trane furnace uses two machine screws to fasten the single front cover to the furnace chassis. I like how yours is executed, so much easier to get access for servicing the unit.
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.
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.
Thank you so much for the video. I was at a loss on my furnace and inches from calling in a pro. Long story short. My burners would not light. I paid $95 American dollars. For a gas valve no help. I spent $50 on a HSI that was getting red hot. Spent $35 on a manometer. Spent hours watching videos and on forums and was convinced my gas company was cutting the natural gas with Helium or argon. I was stumped and could not figure out why it would not light the burners. Oh I forgot the fact that I could light the burners with a match all day and the water heater worked perfectly. I have never seen a burner on the back end. I figured they were just tubes. When you pulled your out I had to look at mine. My Luxaire furnace is a tad different as I'm sure you know. I took the whole rig off and OMG! WTF! The back of the burner was all caked with rust. A few minutes with a wire brush on the end of a dewalt and a pipe cleaner or 2 later. I put everything back together and now my family are enjoying heat. Thank you for your video!
Oh man! Sorry to hear about all the troubles you had to go through before you found the problem. Glad to hear you got it fixed and my video helped! Thank you for leaving a detailed comment, stay warm!
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.
A very good video...Simple, easy to understand and explains the components very well....The flame rod is as you said, the number one cause of no heat and erratic or short burn time.....Close, is the nipples on the draft inducers, usually blower side, get blocked up with crap...No signal proving rotation...A very common problem as furnaces get older, and are not serviced regularly....Thank you for this video...I will use it as a teaching aid.
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.
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.
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
Great explanation of the pieces! I think it's so neat that the technology for the 80% AFUE is still the same it was 20+ years ago since the draft inducer was introduced. My dad's furnace installed in 1995 still has these exact components. I've used your videos to troubleshoot his furnace. Even replaced the flame sensor since it's so cheap (unfortunately that wasn't the problem). Called an HVAC company out, and they went through the same steps you've described in your videos. They concluded it's the circuit board (which the little diagram kinda says too -- if all these steps pass and then it still doesn't work, replace board). The board costs a couple hundred, and they wanted more than 3x that amount, which he even said is what most companies do, so I'll just try it myself at this point since I found an exact replacement.
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!
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!
Nice concise and well edited. I don't see many furnaces but instead have started to open up a wide variety of commercial cooking equipment and many of these same components are represented. Thank you. Will subscribe.
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!
Very well done indeed. Level of detail and speed of delivery is perfect for an overview. BTW... A horse walks into a Tavern...and sits downs at the bar...the bartender says ..."So... why the long face"?
Lol! I didn't expect you to go right into the joke like that. I wonder what feedback I'll get if I use that one at the end of one the videos heheh Thanks! I'll add that to the list of "ending material" ;)
Thanks for explaining. I'm a renter and new to gas furnaces. I was looking for a metal vent on my unit but after watching this learned mine is pvc afterall because it is high efficiency.
Great video,I have a similar furnace and I knew some of the components,but now I know about all the safety sensors,I feel better knowing my house is not going to blow up.LolThank you 👍
I enjoy explaining this to my customers who like to watch me when Im working. They are always very appreciative . Great video and just a suggestion, remove the tape from the door switch when finished servicing /maintenance. Occasionally I have found the door off due to previous tech or homeowner not securing it properly. With a gas furnace this could turn out bad. I use a black zip tie that I push up once finished.
What an awesome video! I’ve learned so much! I have a 6 burner Trane 90% efficiency. Quit heating. I cleaned the flame sensor and condensate trap. Next I discovered the flame rollout sensor is blown. Non resettable. What’s the cause of this sensor blowing? Yes, I’m aware… too much heat. But something needs cleaned. Heat exchanger needs cleaned I think. Not enough airflow through it and there’s literally a flame rollback and over temperature condition that blows the sensor.
Really great video,, as I’ve fix several old style furnaces over the years,,, the Older ones didn’t have all the redundant safety systems,,, these newer ones are a lot different and your information helps a lot! Thank you.
Glad you found the video useful! The newest furnaces are loaded with even more safety features and electronics.. It's becoming a science. Thank you for watching and leaving a comment!
Excellent video, great job. Yours is same as my furnace. In my case, the flat surface igniter is the number one to fail, especially in the rain season. The ceramics is fragile to break under high heat.
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? 😉👍
Great job as usual. Don't forget to mention the purpose of the door switch. And how some furnaces have another limit near the blower housing. Wasn't sure if you had mentioned that. But great video anyway.
Thanks Harry! Yeahh.. I totally forgot to talk about the door switch in this video. I did explain it in some of the comments though. Thanks for pointing it out! Much appreciated :) And I completely failed to talk about a possible limit on the blower housing. Turns out I forgot a few things... Although I rarely see that limit on the blower housing trip, even with a burnt out motor.
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!
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.

Wow! You explained everything in plain English that a non-HVAC person can understand. Thank you!
This is by far the best furnace video I've seen, straight and direct to the point and easy to understand.

Great explanation of the pieces! I think it's so neat that the technology for the 80% AFUE is still the same it was 20+ years ago since the draft inducer was introduced. My dad's furnace installed in 1995 still has these exact components. I've used your videos to troubleshoot his furnace. Even replaced the flame sensor since it's so cheap (unfortunately that wasn't the problem). Called an HVAC company out, and they went through the same steps you've described in your videos. They concluded it's the circuit board (which the little diagram kinda says too -- if all these steps pass and then it still doesn't work, replace board). The board costs a couple hundred, and they wanted more than 3x that amount, which he even said is what most companies do, so I'll just try it myself at this point since I found an exact replacement.
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!
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!
Nice concise and well edited. I don't see many furnaces but instead have started to open up a wide variety of commercial cooking equipment and many of these same components are represented. Thank you. Will subscribe.
Glad you liked the video! Thank you! :)
i was tring to figure out how the furnace water drain worked, but good video, I learned a lot
Great video hands down the best. Quality of video, description, narrative top shelf
Thank you
Great video! Straight to the point, not long and drawn out. Extremely informative, especially for aspiring techs. Thank you
You're welcome! Thank you for watching and commenting!
I have no idea how a heater works but this was very informative and helpful. Thanks
Im an HVAC Student and this helped me so much!!! Thank You
Glad it helped! Good luck in school!
Word of Advice TV same here 👌🏿
great video simple explanation i am going school to get my hvac license ,,,,,it will help me when i will reach this topic.
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!
Time and time again, you never fail to educate me!! Thank you so much!!
Very well done indeed. Level of detail and speed of delivery is perfect for an overview. BTW... A horse walks into a Tavern...and sits downs at the bar...the bartender says ..."So... why the long face"?
Lol! I didn't expect you to go right into the joke like that. I wonder what feedback I'll get if I use that one at the end of one the videos heheh Thanks! I'll add that to the list of "ending material" ;)
Thanks for explaining. I'm a renter and new to gas furnaces. I was looking for a metal vent on my unit but after watching this learned mine is pvc afterall because it is high efficiency.
Glad to hear the video answered your questions! Thank you for commenting!
Great video,I have a similar furnace and I knew some of the components,but now I know about all the safety sensors,I feel better knowing my house is not going to blow up.LolThank you 👍
I enjoy explaining this to my customers who like to watch me when Im working. They are always very appreciative . Great video and just a suggestion, remove the tape from the door switch when finished servicing
/maintenance. Occasionally I have found the door off due to previous tech or homeowner not securing it properly. With a gas furnace this could turn out bad. I use a black zip tie that I push up once finished.
Current apprentice, love your videos!
Best video on gas furnaces by a mile. Great job!
You are the only channel I make sure I get notified for new videos. Thank you.
Thanks Aaron! I will try not to disappoint :)
What an awesome video! I’ve learned so much!
I have a 6 burner Trane 90% efficiency. Quit heating. I cleaned the flame sensor and condensate trap. Next I discovered the flame rollout sensor is blown. Non resettable. What’s the cause of this sensor blowing? Yes, I’m aware… too much heat. But something needs cleaned. Heat exchanger needs cleaned I think. Not enough airflow through it and there’s literally a flame rollback and over temperature condition that blows the sensor.
Really great video,, as I’ve fix several old style furnaces over the years,,, the Older ones didn’t have all the redundant safety systems,,, these newer ones are a lot different and your information helps a lot! Thank you.
Glad you found the video useful! The newest furnaces are loaded with even more safety features and electronics.. It's becoming a science. Thank you for watching and leaving a comment!
Excellent video, great job. Yours is same as my furnace. In my case, the flat surface igniter is the number one to fail, especially in the rain season. The ceramics is fragile to break under high heat.
When taking out of its box, a new surface igniter should never by touched as the oil or dirt on your fingers can damage it.....
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!
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.
Excellent video ! Very useful in understanding the basics of a gas furnace ! Thank You !
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.
Excellent overview. Thank you for sharing your knowledge. Much appreciated.
This was one of the best RUclips vidoes I’ve ever watched
Great job as usual. Don't forget to mention the purpose of the door switch. And how some furnaces have another limit near the blower housing. Wasn't sure if you had mentioned that. But great video anyway.
Thanks Harry! Yeahh.. I totally forgot to talk about the door switch in this video. I did explain it in some of the comments though. Thanks for pointing it out! Much appreciated :) And I completely failed to talk about a possible limit on the blower housing. Turns out I forgot a few things... Although I rarely see that limit on the blower housing trip, even with a burnt out motor.
It’s always so nice to have the Split in the garage or closet and not in a attic, especially during summers. I always enjoy watching your videos 😎
Well, I usually don't work on furnaces unless it's winter time. In Texas we usually don't use our furnaces gor heat.
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 love your videos..they're very informative..makes me feel like a HVAC expert..thanks
That's the cleanest old American Standard furnace i've seen! Great video
Thank you cutting through all the b.s. and busting us the facts! I hardly take the time to like a video let alone comment. Kudos
