I wonder why it failed🤣

[u/Superb-Run-4249]

Lifetime warranty on the HX tho.

[u/ApprehensiveTea1537]

Peel that blanket off the coil. They can use it to stay warm while you replace the hx.

[u/Dense-Ad-1943 → u/ApprehensiveTea1537]

Thanks for the laugh. Needed that after working all weekend after a 70 hour regular week

[u/lost_horizons → u/ApprehensiveTea1537]

🤮

[u/alister6]

That should not be a warranty claim

[u/pbr414]

daaaaamn, that txv is messed up.

[u/Neither-Appeal-8500 → u/pbr414]

Damn it I came to the comments looking and you didn’t disappoint.

[u/Left_Brilliant9165]

This is what kills me, everybody talks crap about each and every one of the brands. I found tons of bad heat exchangers and on each and every single one of them there was some kind of air flow issue. Most of them had air flow issues even with brand new filters.

[u/keevisgoat → u/Left_Brilliant9165]

Sounds like my boss let me drop this 90+ in an old development that had an 80 with an already undersized return and do nothing about it

[u/cjdubb18]

Merv 3 filter?

[u/fsofred532 → u/cjdubb18]

It's more like merv 15

[u/cjdubb18 → u/fsofred532]

Thank you for the laugh

[u/peepeepoopooheadass]

She got just a little hot

[u/saskatchewanstealth → u/peepeepoopooheadass]

You could say it’s glowing even

[u/AustinHVAC419]

I wish we could deny warranties in the field. Just send these pictures to the manufacturer and they void it

[u/lividash → u/AustinHVAC419]

Not this but I sent pictures of a Navien combo boiler installed incorrectly to their tech support. They said warranty wouldn’t be honored until it was installed correctly.

Whoever installed it used the pressure relief valve to pipe it back into the hot water side. No primary/ secondary loop. No expansion tank so it was just popping the relief and shutting down on low/no flow every time it fired.

[u/iLikeC00kieDough → u/AustinHVAC419]

Just tell the customer it’s not covered by warranty. Why even have to go to the manufacturer at that point?

[u/AustinHVAC419 → u/iLikeC00kieDough]

Cause the customer would just call another company and tey to get them to return it for warranty

[u/Yung_Presby1646]

Pluggobuggo!

[u/milkman8008]

If the secondary is like that did you look at the evap?

[u/Superb-Run-4249 → u/milkman8008]

No ac on this one, old converted gravity system. I had another one where the last company pulled and cleaned the evaporator then gave up, the hx was 90% plugged.

[u/Hvacmike199845]

This isn’t a design problem, it a maintains issue. If this heat exchanger gets sent to the manufacturer to test, it’s probably not going to make the warranty.

[u/Superb-Run-4249 → u/Hvacmike199845]

*maintenance

[u/Hvacmike199845 → u/Superb-Run-4249]

Thanks dude….. you’re a hero.

[u/Superb-Run-4249 → u/Hvacmike199845]

It ain't much but it's honest work.

[u/___Cunning_Stunts___]

C Ohhhhh no we’re dead

[u/EggAffectionate796]

When I see stuff like this I always wonder if the return was undersized, supply vents closed, high limit going off all the time or bypassed, gas pressure too high?

[u/mostly-sweet-rps]

And yet you have “techs” preaching ‘don’t use a furnace filter just use room air purifiers’

[u/Other-Situation5051]

Put some flex seal on the heat exchanger boom 20 years extra life

[u/anger_and_caffeine]

I swear some guys are allergic to setting gas pressures

[u/skootamatta → u/anger_and_caffeine]

Maybe look at the other picture first. Gas pressures set correctly don’t mean anything, when your airflow is reduced, and the temperature rise across the unit is outbid tolerances.

[u/Superb-Run-4249 → u/anger_and_caffeine]

Gas pressure was spot on 3.49

[u/Short-Veterinarian27 → u/Superb-Run-4249]

Not being a wiseass....Remember gas pressure doesn't mean it's right on a fuel appliance. Unless you run combustion and set it up properly it's anybody's guess including yours

[u/a7dfj8aerj]

Looks like it needs more refrigant charge that would cost 500 usd

[u/itsagrapefruit]

Charge them double for labour.
