My mom had a Trane a/c unit installed Aug. of 2008. Labor and all 4000.00. When she asked where the manual was, they told her it does not come with one.. how do we know she was sold a new one . This is the Model # 2TGB3F3OA

The answer to your question lies in the Serial number. Below is some info that might help. Also, I think Plumber 101 is a Trane dude, he might be able to help better.

Good luck.

TRANE
Trane used alpha codes in their serial numbers to determine year of manufacture. They started this in 1987 with the letter B and skipped the letters I, O, Q, U, Z
In 2002 they started their serial numbers with the year it was built.
The first letter of the serial number gives the year of manufacture as follows:

9=2009 8=2008 7=2007 6=2006 5=2005 4=2004
3=2003 2=2002 Z=2001 R=2000 P=1999 N=1998
M=97 L=96 K=95 J=94 H=93 G=92 F=91 E=90
D=89 C=88 B=87 S=86 Y=85 X=84 W=83

U=82(seventh digit)
T=81(seventh digit)
O, A=80(seventh digit)

Double check the model number I am not finding anything with the number you provided

what year is my trane a/c

Thank you for your quick response. Here is the serial # 8215LG36V

 

[Plumber101]

The model number you provided is for the air handler not the actual a/c condenser.

From what I am seeing is that it was made the 21st week of 2008.

Thank you Plumber101 for everything.. now to get them to give her a manual.
apparently they didn't sell her one big enough for 1500sq feet home, using a 2.5 ton a/c ...in SOUTH ALABAMA 30 MILES FROM THE BEACH..

I posted links for the manuals .. just click on them and print

Why do you need the manual are you having problems?

Size of my a/c

She's claiming it won't shut off setting at 78. 90degrees outside. The one she had before kept the house comfortable.The freon is perfect and all filters, no leaks.

 

[Plumber101]

Measure the temp coming out of the supply register and return grill and post it

 

[GENATAY]

what year is my trane a/c

OK. I'll be going to her house tomorrow, find someone w/ gauges. It is 80degrees in her home 93 outside. She set the thermostat at 73.

Make sure they have temp probes to measure air temps, and line temps.
Because pressures alone don't tell you anything.
