I did an install today on upflow American Standard CUB100C960-Furnace
Bv29-60 -evaporator coil
Aprilaire-2200

Replace 1982 Coleman single burner 100,00- with 2" hole in heat exchanger.Can't beleive the people in the house survived.Pulled coil to clean/wrong hole in drain pan the size of half dollar.

Just that I usally run service but,the calls were slow so I jumped in to lend a hand and had a good time today with the guy's. Start 10:00 and finished at 3:00..

Inspection tomorrow by city to see if I did a good job.
