FIRST TRANE AC SYSTEM OVER 50 YEARS OLD STILL RUNNING STRONG

[@brnmcc01]

That is a 3 ton unit. My grandfather used to work for GE. He mainly worked at Broadway and Winter St Engineering in Fort Wayne where that condenser fan motor in that unit was made. He also was involved in a project in the 1960's to redesign all their hermetic motors, and visited the plant in Tyler, TX many times. That unit was made in the 6th week of 1971. The last 3 digits of the serial number represent the last digit of the year, then week of manufacture (YWW). The 36 in the model number is the 36000 of cooling. The fan blades were made by Lau in Indianapolis. Good units, I have a set of run capacitors I saved from a early 60's unit from a customers house I just replaced last year. Was a 5 ton, from 1964 when the house was built. Lasted until 2021, something broke inside the compressor, it didn't burn out though, just wasn't pumping anymore and made a terrible racket. The run caps are gigantic, and separate for fan and compressor. They were also made by GE, and still test perfect. 60 years old, and still work, because cans soldered shut, and probably filled with about a pound of PCB's. I'll never use them of course, and after washing off the 60 years of filth and dirt, the paint is still shiny and look new. I guess the dirt protected the paint from fading. My Dad's father just passed away just before last memorial day, almost made it to 102. Worked for GE from 1943 until 1977, then went to work for Copeland in Humbolt, TN then Sydney, OH before retiring in 1985. That's why they're such good units, designed by engineers of the same generation that developed the Apollo space program stuff etc.

[@Spector_NS5_RD]

3 ton from 1/4" x 5/8" (maybe even as small as 1/2" for that suction line) line set? I'm too lazy to do the research on this particular unit. Would this unit be rated at 4-6 SEER if this were, indeed, 3 ton?

[@brnmcc01]

@@Spector_NS5_RD Yes about 6 seer. 4 before he cleaned the condenser coil! That was most likely a 5/16 x 5/8 suction line. So 1/4" ID and 1/2" ID. Yes a little small, but if a short line set not an issue. For 410A and 3 ton, 3/8 and 3/4 is recommended up to 50 feet.

Spine fins were plugged solid, pulled it all apart, cleaned coils, replaced fan motor. Fired up quietly, instantly, pressures were rock solid. Didn’t even need a charge! Runs beautifully. 50 plus years old like me and still going.

G.E. 's roto-lock compressors were unbeatable!!!!! Way back in 1977 when I was a service trainee, I installed lots of these condensing units in central Florida. We had virtually no compressor failures!!! And years later, when I was self-employed on Long Island working all of the Hamptons, and Amagansett / Montauk Point,, I was installing the Trane units and I remember another service tech. telling me about ""SNOWBALL"".... a ~Roto-lock compressor~ that had been running ~deliberately~ with the blower in the air handler shut off for around 12 years!!! That was in 1988/89?!?! AMAZING!!! I WONDER WHEN OR IF IT DIED!?!?!?! CHEERS!!!!

[@phightphan]

GE's "Snowball" lasted almost 28 years, from late 1972 until 2000. Then Trane started up a "Snowball II" in 2000. Last I heard, it's still running.

That GE unit was the best unit we ever had, was supposed to have an outside wedding shower at our house but the forecast was for 100° we had over 40 blabbing women in our house and everyone remarked at how nice and cool it was, that GE had zero problems keeping the house at 72° on a 100° day with 40+ people partying in it.

[@khx73]

Notice the handy little covered access door for resetting that pressure switch @ 33:13.

[@Straycurrent]

That GE is nearly identical to the one I had at my previous house, installed in 1967. If I recall correctly, that control with the manual reset slider is a high press switch with a cap tube extending down into the compressor compartment onto the high side line. The cabinet metal was heavier gauge metal than the body of my car today.

[@markbeiser]

I haven't seen one of those in the wild in a few years. Looks like someone already screwed up the compressor capacitor setup for the trickle crankcase heat. There is supposed to be 2 capacitors, one that stays energized all the time, has a bleed resistor on it, and has that fuse in the circuit with it. The other gets placed in parallel with it when the contactor pulls in. The wiring of that contactor is interesting too, one pole just switches power to the run and start windings of the fan motor, the other pole does the run lead for the compressor, and brings the 2nd compressor run capacitor into the circuit. One leg of the line voltage connects directly the common leads for the compressor and fan motor, the other leg goes to both poles of the contactor. I've had to deal with the aftermath of coworkers getting the wiring wrong on them a few times over the years.🤣 I actually carry one of those GE contactors on my truck, but it has been at least 5 years since I've needed it.

He said his ac guy was keeping is going and it was fine. My dad was an executive and made very good money but grew up in the depression and was cheap. My mother did not work but she did the books and paid the bills. I told her they could save a lot of money on the electric bill, (remember Houston) if they put in a new unit. My good friend was a HVAC guy in the area and he replaced the GE with a Trane system and the electric bills in the long Houston summer was over $200 less a month in 1997 dollars.

My condensing unit is drawing 8.2 Amps When running Plus the air handler fan which I have not checked the amps lately . Pretty damn efficient. You must keep your house very warm as that has everything to do with how much electricity you use. If you never turned your air conditioning system on during the summer your electric bill would be very low so you’re not using any science with your statement. My electric bill is around $35 in the winter with gas heat. You can only compare your electric usage to you or an identical house and Ac. You cannot compare it to other people as there are many many variables involved from one house to another and system to system. Your electric bill has nothing to do with my parents house...
