In this video I replace the secondary heat exchanger in an old Payne furnace. This component is not the most enjoyable part to replace but we do run into it once in awhile. Hope you find it helpful and interesting!
Ok, seriously, this young man has more mechanical aptitude than many 25 year HVAC techs I know, he’s going places. Well done 👍
You know a man is good when he makes it look easy 😉
My secondary heat exchanger is plugged. Your video helps a ton
this is the best and not surprisingly shortest video on the subject. watched this and another video on how to disconnect the gas line and pulled my old heat exchanger out in an hour. thank goodness for young people who know how to communicate and edit
Outstanding presentation, Reuben! And it's great seeing that the whole job can be done in about 12 minutes ;-) You're seriously talented, smart and focused. Everyone associated with you in real life is really lucky. Good luck, man! Have a long and very happy life.
Thank you very much for sharing. Few days ago I did the SHE replacement by myself based on your video and very straight forward. I spent almost $1500 tax included on parts, save my a lot of money compare to replace a new furnace ($5000 to $6000). My furnace is out of warranty, it was installed in 1998 but still worth for repair (overall the condition is close to prefect).
This video is superb- well done my good man
Excellent video! I am a do-it-yourselfer when it comes to most repairs. However, I had been very apprehensive about replacing my heat exchanger in my Carrier Weathermaker Infinity, until I saw your video. Everyone had been telling me it was too complicated and not worth putting money into. All the furnace outfits are trying to sell me $8000-$13,000 replacement units. I don't have the money to do this. Thanks for showing us how relatively easy the job is and can be done by us common folk!
It’s this easy if you can pull your whole furnace and and do it in a shop. In a real life scenario it’s nowhere near this easy. Especially if you have a horizontal unit and a small attic space
Oh the horizontal ones are absolutely terrible! The tabs that center the heat exchanger in the furnace are so hard to install if it's horizontal. As far as doing in the shop versus in the field, it's a pretty similar process. Other than the gas, venting and electrical already being disconnected it's the same process. Here is a time lapse of doing a different one on the job.th-cam.com/video/Dt_aNzbZR6A/w-d-xo.htmlsi=-9FD7tZfdWuMny-e
A new furnace doesn’t cost 8,000…😂
Screw that. Im just gonna replace the whole furnace. Thanks for saving me the headache
I found this to be very helpful, i want be doing this job
Thanks, this really helped. I put in my first heat exchanger today.I had only done this with another tech once before, and it was several weeks prior to doing this.
Glad I could be of service to you! It is quite an involved job. I have done at least a dozen of them in the last couple years, so I have it down pretty good now.
Brother, you have a future on TH-cam. To be successful on YT, you have to be knowledgeable of the topic, show in detail what you’re doing, and you must talk throughout the video if it’s instructional. And you have the gift to gab. And a good editing department helps as well. My Carrier 96 Keeps shutting off and the flame roll out switch keeps tripping. At 12 years old now, I’m guessing it’s the secondary heat exchanger. This is a great video. Thank you.
brilliant channel
Thank you for sharing. Going to try it soon!
The local Carrier dealer who installed my 58MVP furnace 18 years ago replaced the bad coated heat exchanger FREE OF CHARGE under some sort of extended Carrier warranty AND guaranteed it for the next 40 years. This and other similar videos seem not to mention this.
Sounds like a good deal! This video is not about warranty, but is actually just about replacing the secondary heat exchanger.
Very well done! Definitely not a job for beginners!
wow you made it look easy
Great job man
Reuben knows majic
Very helpfull video. Thanks boy.
nice job. great knowledge.
thanks for sharing
You're welcome!
You don’t have to take the burner box off at all, that is extra work that is not necessary
Hello buddy ✌️ Reuben good video buddy 👍 I hope you had a wonderful Christmas and New year day and I wish you have a wonderful prosperous new year and a healthy one my friend 🙏 god bless you and your family.
I like how the 60fps looks.
Nice video. Did you have to notched about 1/4" off the inducer legs to get the inducer to seal properly against the new secondary heat exchanger? Thanks
Thanks!
No, I've never had to do that.
Awesome, thank you
Great video. You make that look easy. I have the Carrier of that furnace. Flame rollout switch trips after running about 10 minutes. Flue CO is around 2000. Intake and flue vents are clear. I suspect the heat exchanger but seems like cost will be almost as much as just replacing the furnace. My furnace is only 11 years old but still leaning toward full replacement.
Yessir sounds like you have a bad heat exchanger! Also, it's 11 years old, so no warranty. When there is no warranty on the parts it's best to replace the whole thing. It seems that the second heat exchanger only lasts like 5 or 6 years, and by then you're starting to replace other parts like combustion blowers, igniters, blower motors etc.
@@ReubenSahlstrom Yeah, that's what I'm going to do. I'm seeing a lot of the manufacturers are offering lifetime warranties on the heat exchanger. That's awesome. Did you ever do a video where you tear into a bad heat exchanger? I'm curious to see what it looks like.
I have not made a video about it, but I have looked at them and used them for target practice. When you shoot them up you get to see the corroded layers pretty well. Maybe that is a good video idea... 🤔
20 year warranty on heat exchanger.
As farmer said. 20 year warrantee on primary and secondary
Amazing!
Your a legend 👏
I have two nineteen year old bryant gas furnaces. The exhaust vent motor blew!. Pieces of the vent motor assembly everywhere. I put a new one in myself (4 screws). Works like new. I was wondering at what point do you buy new furnaces? If I were to replace the blower motor, the vent assembly and the heat exchanger would the furnace go another 20 years ?? Great video! Thx
In my experience, a furnace will go about 15 years before many major important components start to fail. Once a furnace is past 20 I think its best to upgrade, rather than play repair whack-a-mole. When you install new heat exchanger parts on an old furnace they tend to last about a third of what the original components do. Not entirely sure why, but replacing the heat exchanger only kicks the can down the road a few years.
Hi I am from NYC I need to order heat exchanger to my air franc unit
I loved the puns of payne you popped in the video. You made an impossible job seem simple.
This was a painful video. Today I found out 2 furnaces are bad (gas bad) and the 3rd floor one is a side mount Payne and looks just like that. Tomorrow I is going to be a sad day as start figuring out the resolutions. I'm suspecting it's replacement so I started my research tonight. With such a tight space with zone controls too, I suspect I'll be hitting a few roadblocks.
If the cell panel is sooted up like that it, it must be replaced. Primaries as well as they are also full of soot. The updated coupling box kit is stainless steel, you must not reuse the old coupling box and cold spot baffle kit. It is required to replace the coupling box when replacing the secondary. The entire heat exchanger should have been replaced in this furnace. Carrier is anal on warranty, but if you are with a good part supplier, this won't be an issue. Oh and those small metal pieces on the back of the secondary stay in. The replacements all come with them for a reason. Carrier tried multiple different things back in the day to try and negate their poor design failures. Some models have them and some don't. I have opened a new secondary up and those were missing, had to take the old ones of the first heat exchanger. They have to be there. Absolutely 100% they stay in place.
What is the advantage of an extension bit?
What if the baffle was placed covering the main heat exchanger instead of the secondary?
Nice and easy when it is not connected to anything and in good light with nothing around.
Yeah no kidding! My 'favorite' places that I have done them are attic crawl spaces, and horizontally mounted garage units 14' off the ground. Those are the jobs where charging extra is advised. 😂 I had to video this one since it was such an easy 'out in the open' job.
With so much soot contamination, isn't it better to replace the primary cells and inlet plate too?
I know this is more of a demo to show how to do it and what's done for customers could vary.
I assume you're re-using the furnace?
Yes, this furnace is maybe going to be reused, as its heat exchanger was under warranty and the owner did not want to keep it and opted instead for a new unit. The furnace is in rough shape, and won't probably run for many more years.
@@ReubenSahlstrom ya sounds like it could make a good shop heater.
Did you get the heat exchanger replacement under warranty?
Hi Reuben ,could you please tell me to to remove one of the PVC pipes, the one that is not connected to the Inducer fan Motor ,the one real close to the Gas Valve. Thanks !
😂 I forgot to mention removing those since (obviously) this furnace was in the shop, and not in the field. But yes, I can tell you. Eh hem. Please remove the PVC pipes before proceeding.
So does this teach people how to replace polypropylene secondary heat exchangers knowing they delaminate when they overheat and the breakdown is corrosive. 2007-2012 carrier 90% need to be replaced with different brand if they utilize poly
Just curious what this would cost from most hvac companies. I would assume we wouldn’t be taking the furnace out of the ducting.
If parts are not under warranty, you're probably looking at $1000-1400 in parts, and probably $400-600 in labor depending on the furnace orientation and environment (like if its in a crawl space). Also, this only buys a few years for the furnace in my experience.
Here is a link to a time lapse of an on the job replacement. You don't have to have the unit disconnected from the duct work at all. ☺ th-cam.com/video/Dt_aNzbZR6A/w-d-xo.html
Class action lawsuit on the the Bryant's so I assume Carriers would be covered too. I got my primary and secondary and all the parts replaced for free and did it myself. Not a big deal really. Don't let the sales folks scare you into a new furnace and a $600-$900 gift card. The invoice I got with the parts was $2440........that should be the credit towards a new furnace should you decide to go that way in my opinion. P.S. The secondary is made from poly-laminated carbon steel that separate and plug. That is why they fail.
I have an older 1996 Carrier 58MCA080 would this unit be included and covered by the class action lawsuit?
@@DJ_Driven too old, buy a new furnace, stupid to change at this age even if it was still under warranty. 80 000 btu could be oversized, too large for many homes. 40 to 60k heats most homes unless in an area where drops to like -40.
Yes i cleaned that out and it seemed to dry out for a few days then right back where its leaking
Hmm, well, I think you would have to call Comfort products and they would be able to tell you how to get a new heat exchanger. If it's not under warranty they'll typically cost upwards of $900, so it might make more sense to put in a new furnace. It might not be a bad ide to have a combustion analysis done on it to to confirm the heat exchanger is bad. If it's all rusted through and leaking as a consequence, then it's bad. Good luck!
@@ReubenSahlstrom I have a 1996 58MCA080 is there a way to inspect to see if my heat exchanger is bad maybe even using a Milwaukee inspection camera?
Mostly you'll know it has issues by seeing a few other odd things. If the exhaust is sooty, the rollout switch is tripping, or there is water dripping down from a over the blower motor, it's likely you have a bad heat exchanger.
th-cam.com/video/coLH6tEeT8c/w-d-xo.html In this video you can see the outer corrosion on the secondary heat exchanger, so if you were to non invasively inspect it with a camera this is what you'd look for.
@@ReubenSahlstrom swapping out a seized inducer motor tomorrow. The HVAC shop tech said since my trap hose cracked through that's a dead giveaway the heat exchangers are bad. He said the fluid gets acidic and damages the rubbery.
Also I understand there is an extended warranty because of a class action lawsuit on these furnaces.
could it be that carrier would give me a heat exchanger for free or does everything have to go through a dealer?
I am guessing they would be leery of sending it to someone who is not a dealer. Are you the original owner? If I were you, I would contact the dealer who sold it to you and have them confirm it's bad, and get a new one IF it's under warranty.
These furnaces had multiple recalls with there secondary heat exchangers and comes down to poor design and flaw in materials used, even if replacing it, the new heat exchanger is same design and material and may only last 4-6 years. Usually recommended to just toss these furnaces all together
Where can I find and purchase a heat exchanger for my Carrier 58MXA100-16 furnace? I can't seem to find parts lists or diagrams.
Good old 58mxa, huh? Not surprised the heat exchanger is bad. Carrier doesn't like to sell to private people, so you'll likely have to go through a dealer to get one. Depending on the age of the unit, and wether or not you're the original owner there may be heat exchanger warranty. The warranty typically covers the secondary heat exchanger and labor to install it if I remember correctly. If you have to buy the heat exchanger, I would recommend putting the money towards a whole new furnace, as the second heat exchanger typically lasts a fraction of time compared to the first.
I have water leaking out the bottom of my carrier furnace. This is what i need. where do i buy a heat exchanger.
Before you plan on replacing the heat exchanger, you should make sure you don't have a condensate backup. Take the white condensate trap out and wash it out really well. If those plug up water will back up in the heat exchanger and eventually find a way out.
In process of fixing this myself, I just can’t replace whole furnace at this time but I am in need of said baffle at about the 5:37 mark is it possible that you would know the part number for this baffle because without it I can’t move forward one I removed is trashed😢 thank you for any help
Carrier 58MXA100-11116
Unfortunately I don't have it, but I would recommend calling Comfort Products. If you give them the model number of your furnace they will be able to get you the baffle part number. Good luck on the project!
Found a parts list on website great help keep up the good work!!
Is there a lower cost supplier of these secondaries? I have an account with two suppliers and the one I need is still $1400+ for a 60k/100k.
I am not sure. It seems to me unless the part is covered under warranty it makes more sense to install a new furnace than to replace the heat exchanger.
can't you buy new furnace at cost for that kind of money?
Cheaper to buy a new furnace.
Shame on Carrier. They know this secondary heat exchanger design is flawed, yet they still manufacture it and do nothing to fix it even after it’s taken the lives of multiple people.
Actually, they don't use this secondary heat exchanger anymore. Still a big bummer about how poorly these old ones performed though. Tomorrow mornings video shows the newer design of heat exchanger.
@@ReubenSahlstrom better super late than never I guess…
probably if it's real old, you just replace the whole furnace-right!
Yes, quite often that is what we do. This heat exchanger was under warranty so we replaced it, but the owner decided to put in a new furnace anyway.
why not just buy a whole new furnace & new air duct system?!!!😁
Yeah why not?
It boggles my mind that companies charge over $5000 for these things.
Wrong. Never replace that junk. Right in the garbage. Install a new any brand and FIX THE DUCTWORK!!!!
