Hey thank-you very much.!

compressor 100

As requested. By the way the suction connection is on the top. New unit is the same tonnage.

Looked everywhere but must have lost it.

Update picture please,

Hey selfemployed, Can you please repost or update this thread call "Ge 10 ton"? Thank-you

Very good post. The first time I used this method was in 1969. I was a GE dealer. Used to use the torch with what GE called "A Lazy Flame". Great to use on dog hair. That serial # is Feb. 1972. I have a lot of old res. units stll kicking with the dome top. Installed thousands of them. Love that roto-com and the 3 legged mount. Some even had a fuse on the run wire.

what does the air handler look like?

I got one too

Hi i am currentlya business owner and i have one of this unit and the compressor just went bad and i cant find one, im going to upgrade and i see there quite a few fans of this old GE's, anyone interested in buying this dinassour?

INFORMATION YOU NEED IS IN YOUR NECK OF THE WOODS.

That compressor looks like a 7 tonner.You'd be suprise to see that baby run as its name implies- for many years to come

Those old GEs just keep on going. I worked at an apartment complex and the majority of their units were old GEs from 1972-73. and a lot of them are still going today. I didn't like the trickle circuits tho when I was just starting out in HVAC I would get the crap shocked out of me all the time.

Old equip.

Nice pics alltemp they do last beyond their time. Had to clean and replace gaskets on a few condensers like those. gschra11- that was a joke inpart The old stuff just wouldn't quit and were built to last. Cost of repairs causes most equip. to be replaced today, even when its less than 10 yrs. old. Thats not all bad.

Yea but lower seer units last longer and don't have many gadgets to replace so they cost less in the long run.

Not true... if you compare a heat pump made today to one made even 20 years ago, you'll find there are no mechanical timers, coils, relays, etc. Many of these components have been replaced by simple solid-state controls, and have thus eliminated potential component failures. Air Conditioners made today are made pretty much the same as 20 years ago... motor, compressor, contactor, capacitor.

I give you that the quality of the components themselves may have changed. That compressor is a tank, and nobody makes them like that anymore.

Water Tube Condenser

Shared this before , this old Carrier R12 was running when we changed it out...

They don't make quaility coils like this any more.

This coil installed flat and the louvered condensate pan caught dripping condenstae. 40+ years old and no leaks :-)

LOL

coil crud

Could also install a UV light near the coils. The light will clean the crud off quickly and prevent it ever coming back. Just leave the light on.

Thanks

I'll give that a try. Printed to show trane dealer I use to work for. If it works I don't care if it sounds crazy.

The propane torch trick

Spine-fin is all-aluminum, and since the way they make it involves aluminum spines sticking out instead of aluminum plates, the spines can bend very easily. For this reason, you can't hit it with a jet of water because:
1. The spines will bend over and the condenser will become useless
2. The spines don't like to release dirt, lent, cotton-wood fuzz, whatever.

Therefore, the only way to clean Spine-Fin is the propane torch trick.
1. Turn unit ON.
2. Take as many panels off of the unit as you can. For GEs and even most Tranes/American Standards, you have two that you can take off. (Opposite each other)
3. Tell the homeowner that he/she is going to see smoke and not to call the fire department, everything is ok. (Actually had this happen once)
4. Get a propane torch, light it, and put the flame on the spine-fin. Go down each row with the torch. Don't keep it on one spot, keep it moving, but don't rush through it either. You want to see the dirt glow red, smoke, burn up, etc.
5. Do all four sides, even the ones with the panels still on. GE and even Trane and American Standard today have made their cabinates able to stand the flame without hurting the paint.
6. When the coil looks grey, (ashy) then you have burned everything. Turn the unit OFF.
7. Take a garden hose and gently spray the coil with a shower of water. DO NOT HIT IT WITH A STREAM!!! Everything on the coil is all ash now and will wash away very easily with gentle water.
8. If you did it right, the coil will shine and look brand new.

...and don't worry, the head-pressures won't sky-rocket while you've go the torch on it, because you are just spot-heating the condenser.

No, this isn't some crazy thing I dreamed up. This is what Trane said to do at one of their training sessions. It actually works very good.

Hope this helped.

Propane torch trick? Could you elaborate on that?

That looks like classic spine-fin coil to me... Same thing AS/T uses today.

Didja use the propane torch trick to clean it all? It's the only way to clean spine-fin. I have a blast everytime I do that. Guess I'm a real geek.
