No. There is no trick either. Just fire u a mapp torch with a medium low to medium flame and play along the coil. You don't have to touch the coil cause the heat from the flame burns off the build up before the flame even gets near the coil.

And Ace, you got 30 years in like Uncle does....but he never stops learning even though he is not 100% health-wise.

Explain why it is asinine...the flame does not even touch the condenser..

If you can't explain why this method should not be used don't judge others who do use it, please.

Your statement about burning the side of a house is a far fetched one and is not a valid worry. You could cause that damage during the normal process of brazing a line set. And yet we don't go to mechanical connections to connect our evaps and condensers.

If we use your logic than we should refrain from fixing leaks in lines that are in tight joice spaces too....so we would have to run new line sets instead.

I am going to ask you again to please temper your responses. I am not your enemy.

Spine fin coils


A couple of things.
If you understand the engineering behind heat transfer you will understand that the transfer is at the edge of the alum fin.With spiney fin you have easily 2 or 3 more edge than flat alum fin design.
The reason no one else uses it is because it was patented up til abut ten years ago.As the patent expired Carrier jumped on it and even bought some machinery.Then they found out they didn't have the design to attach the alum coil to copper pipe.Trane still has the patent on that.
The other thing is that with flat alum fin it gets dirty from the actual tubing out,whereas the spiney fin collects "dirt" from the outside in.That may sound like a small thing but it makes cleaning the coil a lot easier..

Does this have something to do with the topic of burning the coil clean or are you just posting an interesting fact?

Rep, I believe that you are the only person that thinks that the spine fin coil is easier to clean.

Do you often clean them or are you a Trane salesman?

I strongly disagree with your opinion.

"The Tech" whoever he was is wrong it didn't state anywhere in the manual to take a torch to the coil to clean it he said he heard it at a Trane school/ Seminar whatever. No proof what School/Seminar whatever or who said it. I think it's nothing but BS. Maybe the way he's cleaning it really works but no where did Trane recommend to do this KOOK cleaning. This is a recording the real spine brush recommended for cleaning spine coils. Com' on PRO"S don't fall for this. By the way anybody see Santa Claus or the Easter Bunny lately.

Carrier had spine coils back in 1980 with that small trash can sized unit with the triangle shaped compression fittings. Not a bad unit as there are still a few running after 30 yrs.

I have had one oil furnace get flooded with oil and take off on me and needed the fire dept to keep the house from burning down. One of my plumbers burned 1/2 a house down soldering under a sink and caught the wall on fire. My company would fire us instantly if they EVER saw us doing that and with the devious customers these days they are just looking for ANY reason to sue or complain etc. My unit is now noisy because he burnt it yada yada yada. NO way would I ever do that procedure. Dry leaves in the unit and grass and bushes etc etc are just waiting for a disaster to happen. Once you have been thru a few fires you learn to be careful and not tempt fate.

Well everyone is intitled to their own opinion but I was told the same thing at school in Tyler TX.
Now cottenwoods are nearly everywhere but that is about the only reason to used the heat method to clean the coil.
Normally you just need to spray from the inside out for things like grass clippings.
Those coils are not that hard to clean and because they transfer heat so well,you will find very few with two or three layers of coil which also makes them easier to clean.

not getting into a pissing contest with you, i have stated my case and made it very clear.....if you don't like what I have to say then you have two choises........don't read my post or never apply to work for me.......either way Is fine with me. for the record, It doesn't surprise me that a Tirane manual would suggest a "lazy flame" to clean off cotton wood....i mean who benefits when you have to order a new coil, to replace the leaking one ? LMFAO @ you and Trane.....

Using a torch is very common place on the spine fin coils. Never heard of anyone losing a coil from doing it(lazy flame).

But each to his own.

Name calling however will not be tolerated.
