Thanks Tad, you're very thorough and that is why you found the cracked heat exchanger, too bad for the customer but good for their health and safety, they were lucky to have you as a service tech.
This was one of those that start out small but cost the customer dearly in the end. You did save the customers and families life. Finding that heat exchanger full of cracks , praise the Lord. Hallelujah.😊😊
Very informative and well done video. All the right talking points. I learned a lot. Having come from an Industrial HVAC background, I feel that I have a lot to learn in the residential/commercial sector where I now own a business. This was very helpful. Walla Walla Washington.
Thank you so much for this. I live in Iowa and we recently had 100 degree weather and my ac went out. Now the heat has passed ive found this and after replacing multiple parts (one was actually broken) this helped me truly troubleshoot and confirm. People like you posting these educational videos are real heros to people like me struggling to get by and unable to afford to hire someone.
I really appreciate you. Thank you so much for watching the videos. I'm so glad you let me know how i've helped and that to me means everything you're the.Reason I keep doing these videos
good Job guys, I am an HVAC tech with few years of experience and i just came accross your video out of bordom amd wanted to appreciate what you are doing, keep it up
Man, I like and enjoy very much your teaching scenarios, and troubleshooting a lot. I do HVAC but not like you residential/commercial. I only do apartments complex and pretty much is the same each day, since is the same property. Every once an awhile I do City Residential. But definitely I'm learning and keep learning by watching your videos. You're the best!
Awesome video. I’m gonna rewatch and take notes. I’m an hvac student in Florida and I am confused about direction but you helped me with information thank you.
You explained that very well and a lot of helpful information for young technicians learning the trade. My name is Eric and im watching your videos from Baltimore Maryland.
I did learn quite a lot from this video. I'm not a pro, but I can usually fix things with the right research, and you just provided some no-nonsense information that's gonna save me a ton of cash. Thank you.
Your video was amazing from start to scratch, well explained, i bet you a camera scope would not find that crack, hard to find cracks with a camera, but you did everything the right way, good job!
It is helpful to see someone else take time to find out the root problem and not just try and quick fix the symptoms. The part was telling of another fault. Excellent
Sir, that was just about the most helpful vids I have seen in a loooong time. Thank you. Saved me a world of headache. BTW I love those Maxi Flex gloves - all I've been using.
A better filter will keep those heat exchangers clean!! 😊 I’ve been doing HVAC for 17 years, I’m located in Eastern middle Tennessee. You make really great videos! Keep it up!!
My furnace stays running nonstop but blows no heat. You can feel the warmth by the vent but no warm air blows. I had two servicemen come but they only offer me to buy a new furnace from them. So far no repair yet. I hope its okay for the next 2 months. Damn they say board is bad $600+, fan motor bad $1000+ and need a new thermostat cuz mine has mercury., and a new furnace will run $4200+++ not including yearly service cleaning. I like to just get it repair but not having to buy a whole new furnace when not necessary... Is there any honest repairman out there???
I have a furnace with 140 limit switch open, now I can believe it is a cracked heat exchanger. I was speaking with co worker over phone and found it. Thanks for the info.
I learned a lot from this video. The biggest thing is the way to check in the limit switch is open with the thermistor, thought that it was only used to find super heats
Great job explaining all the details, Tad!! You are a Natural Teacher; I’m impressed. And now I’m off to see if I can figure why my furnace turns on for 30 seconds and shuts down. Thank You, Kindly, Tad.🙏🏼
Did you find the problem cause? I'm about to head to a friend's house with the same issue. Hoping it is a dirty flame sensor or dirty/bad limit switch.
My boss and the customers think I should be able to do all this in like 20 minutes, by myself in a cramped attic space. lol You pretty knowledgeable tech Taddy. love your vids.
There's definitely a better way to solve this issue and come to the same determination Tad did you definitely don't have to remove the entire heat exchanger to tell that the heat exchanger is cracked There's so many ways to tell this without doing this process
dam thats a big ass crack. i always put a box for 3.5 ton ac or anything at a 100kbtu and over. you offered to fix first before replacment. i beleive in building value with the client. when they see you actually care they will throw whatever you offer them. good work. im from illinois lol
I've been doing this for about about 20 years or more and I always add to returns to the big 90s like that. That dirty coil also could have contributed to that bad exchanger. But I would have never probably caught that without breaking it down myself because it had a rich nice blue and white Flame. In my experience over the years usually when that boy cracks I get some orange in the flame. Thanks for the tips I'll add this in my notes of troubleshooting. Love your content you do an awesome job peace and blessings😂
Great video!!, from duplicating the problem and showing how to diagnose it and then the cause,Thank you for putting this video together. I definitely learned something new. I will now remove my blower and inspect the second burner. You are appreciated Sir.
Yes! Taddy So much info. here! This Really Helps us who are out in the field troubleshoot, and be observant to the symptoms we see and the study we've done on heating and A/C. Very Good Video! Thanks! @@TaddyDigest
DUDE YOUR THE MAN, Jan 1, 7 am, 58° in the house. What a way to start a new year. I have several furry animals so I change my filter the 1st of every month. Just so happens I used the last one in the case. It must have been in Nov so I missed Decembers filter. Shut main power, would kick on four 4/5 min, then Shut off. Had no idea lack of air flow would kick it off by being to hot. By the way everything was clean in the furnace with all new A/C 6 months ago, new inducer 1 month ago. Thank you so much for making this video. Have a Prosperous and Happy New Year.
My exact scenario ! House temp dropped to 56 degrees Hot at the heat tubes flames great but look warm heat from all the registers , new filter will pull the blower out and look at the secondary heat exchanger but thinking the worse ,...........
DUDE. Thank you for this extremely useful video. Super appreciate you, was able to get my old ass furnace back up and going until a real repair guy came by finding a switch with rusting connectors using your multitool explanation, and deoxidizing the connections! HOORAY
Considering the space above the units most of the time, i never understand why not lift the unit up and take return from the bottom as well. Good catch on that HX
Tad, you guys in Tennessee really know your ac/heating trade. im glad i follow you bc even tho ive been doing this for 22 years in Fl so no gas furnaces much, i learn something new from you each and every time, cause and effect! Thanks for sharing.
Really great informative video. I'm having an issue with my garage furnace my cousin sent me this link. I'm a plumber in illinois. The garage heaters a lot different it's one of those ceiling hung units. I changed the limit switch thinking that was the issue. It's not. I'm going to run some tests and check out the coil but this thing just keeps on shutting off on me. I was also going to try and change the thermostat. This thing was working fine and then it just started shutting off after 5 minutes of operation.
I do what you do but I just pull one screw out of limit then stick my “k” type thermometer through that. Or pull limit, foil tape, then poke thermometer through. 😅 100 ways to skin a cat🤷🏼♂️ I’m in year 3 an always refer to your videos, thanks for helping us all out🤘🥃
That's a costumers are looking an a Technician a true if not the good one but find the heat exchanger a crack that saves the family life but at the end it costly damage to the pocket but money is money life is important. I'm retired but still looking to learn something good. From Toronto Canada good job Taddy. Keep up the good work to help costumers.
Thanks I thought i had a bad limit switch. Turns out it was just doing its job. My intake is plugged somewhere. As soon as i let some air in the intake side problem went away. Off to find the problem now.
Best HVAC video I’ve seen, you couldn’t have explained it any better. Thank you.
Wow, thanks!
@@TaddyDigest dude, you are better than any instructor I've had. Keep the videos rolling, you're gonna make me rich.
Really means a lot thank you so much
@@Caesar-nq5if For real! Most people would have never noticed the return size being the culprit but makes perfect sense. This dude is the HVAC GOAT!
I’ve learned so much in this channel
Thanks Tad, you're very thorough and that is why you found the cracked heat exchanger, too bad for the customer but good for their health and safety, they were lucky to have you as a service tech.
I'm about to get out of medical and back into HVAC. I'm addicted to this channel
Really appreciate you watching brother
@@TaddyDigest seriously, you are the Compressor Professor. I can't wait to start my LLC and I have you to thank
That's awesome the compressor professor 😄 🤣
This was one of those that start out small but cost the customer dearly in the end. You did save the customers and families life. Finding that heat exchanger full of cracks , praise the Lord. Hallelujah.😊😊

Glad you like them!
Such a good diagnostics test/learning video. IM SUPER EXCITED
No better in the business than ol Tadd. He's a master!
Very informative, didn't realize that there was so much involved. Looks like keeping the coils clean is important. Thanks.👍
#1 hvac guy on UA-cam. Enjoy these videos dude.
it was very important for my education, thanks for your time from Chicago IL.
Thank you.
AC coil was plugged.
Switch was doing its job.
Glad it helped
It is helpful to see someone else take time to find out the root problem and not just try and quick fix the symptoms.
The part was telling of another fault.
Excellent
The modern "health care" system works the symptoms and not root problems as well, and we know how healthy Americans are.
Sir, that was just about the most helpful vids I have seen in a loooong time. Thank you. Saved me a world of headache. BTW I love those Maxi Flex gloves - all I've been using.
The best HVAC guy
Thanks, you helped me to solve a problem when 4 other technicians before me can't find.
Your videos are liquid gold!!!!! Ty bud
Glad you like them!

What MERV rating for a filter do you consider optimal for air cleaning but not too restrictive of air flow? Thanks!
¡Gracias!
Thank you so much you made my mouth drop open. That's awesome
Failed heat exchanger and a fist bump hahah, can't imagine why 😂 Good work guys.
I have a furnace with 140 limit switch open, now I can believe it is a cracked heat exchanger. I was speaking with co worker over phone and found it. Thanks for the info.
Hello sir. Just want to say I'm new to your channel and the content you present is excellent!!!!! Great Job!!
Your attention to detail caught my attention while researching some troubleshooting. Keep providing, they're great!
Great job bro Pedro from Tampa FL leading every time with U.
I had a bad limit the other day. It was on a package unit though so it got corroded. Great video once again!
Great service brother,good job 💯
great work and thank you, i am visiting you from Atlanta Ga. keep helping me be a more proficient technician
Nice troubleshooting & nice find on the heat exchanger ... Good info Tad ... Thx

NTE bruh
The same thing happens with me 😏
There's definitely a better way to solve this issue and come to the same determination Tad did you definitely don't have to remove the entire heat exchanger to tell that the heat exchanger is cracked There's so many ways to tell this without doing this process
There's definitely different ways.What if the flame is blowing out?That's a definite indication
Great video, especially the cold air return tip.
dam thats a big ass crack. i always put a box for 3.5 ton ac or anything at a 100kbtu and over. you offered to fix first before replacment. i beleive in building value with the client. when they see you actually care they will throw whatever you offer them. good work. im from illinois lol

great vid. Appreciate the trouble shooting narration!
Nice diagnosis, thank you
Great video. You explained everything just fine. Thanks!
I learned that the 5 ton needs 2 return. I also like the servicing advice from cleaning the heat exchangers on maintenance. Thanks
That was impressive diagnosis... Well done. Still scary though, fearing mine will dump out on me..
Great video thank you!!
Bro thank you, for spreading your knowledge u rock. I wanna become a super tech just like u.
You can do it!
I hope you start posting TikTok from Mitchell SD because I used to fish 🐠 around there as a lived in SF
