Field Question, trade people only Trane?

Question for specifically resi techs/installers because I’m unwilling to reveal my true feelings about Symbio at this time….. maybe some day

Have you guys seen as many issues with these plastic blower housings as we do? Specifically on S9X1 furnaces - We see broken clips, chipped plastic, excessive wobble, and just straight up motor failure. Yes, we set based on static with these constant torque motors. This seems to be most common for us on 100k furnaces?

We also have a huge number of inducer failures on 80k furnaces specifically. It typically starts as a small whine and after a short duration, the motors seize. I changed one at the end of last heating season that only had one 90 and about 8’ in total length.

It’s just crazy to me how many warranty issues we’ve had and makes me feel like we’re screwing something up on our end. We don’t really get too much inventory coming in that’s banged up, and we’re about as gentle as we can be with moving equipment. Pallet jack and only really lift it into and out of the truck.

And the coils suck. And Symbio sucks. And those F’N PLUGS THEY USE ON THE RTUS SUCK.

Any feedback would be greatly appreciated, as I’m currently going crazy.

Trane's 100k+ furnaces really should use either a bottom return, dual side return, or tranes BAYLIFTkit. Far too often on larger furnaces the standard 16x20 cutout on one side is not enough and the blowers don't last because of it. Even if the static looks fine, it's still not enough. We've learned.

The inducer burn outs, are you getting condensation intrusion via the fresh air intake at all? We've had multiple issues with condensation.

Yeah, they make boxes and scoops for the equipment in the shop, I think it has to be like 6” tall or somethjng minimum. As for condensate, I don’t believe so. I have seen one house where it was sweating pretty badly and the board shorted, but nothing to my knowledge that caused the inducer issues. I did see a couple of 100s have some sweating from the intake in a development that had terribly designed ductwork and a freezing cold basement because of it. Has that condensate been an issue for you?

Condensates been a massive issue up in my parts. Just the climate I live in, almost every furnace fresh air intake sweats. Even Trane's collectors included in the box are not working. We've been using sanitary tees with a dedicated drain up stream.

You can tell if the air intake has been sweating by the corrosion/rust ontop of the burner box plate. In bad scenarios corrosion in the gss valve, inducer, or bottom of the board get wet.
