Trane XR90 Furnace Overview

One would think that after discovering that the plastic collector flange, (that Trane considers part of the heat exchanger), routinely develops “cracks” where it attaches to the plastic “transition piece”, it would have issued a factory warranty on the defective part that can lead to moisture leaking onto the control board, or worse, leakage of deadly carbon monoxide. It would appear to me that the crack was caused at the factory when some knucklehead overtightened the screws connecting the transition piece to the “collector box”, causing the screw attachment knob to develop a crack. So, a $1.00 piece of cheap plastic now necessitates a $1200 repair or a completed replacement. What a scam! What a racket! Shame on Trane and their “trane-wreck”.

Bought two Train furnace A/C units 7 years ago. Had them serviced for A/C and found that in both furnaces the condensing coils were gone and had to be replaced. The second furnace also had the heat exchanger cracked and it had to be replaced also. With the cost of these items, we decided to replace the second furnace and A/C unit. Needless to say, we did not buy a Trane. Both of these units should have lasted longer than 7 years. Contacted Trane and got no reply.

I own over 50 rental houses and have installed Trane systems when I updated the hvac systems in many of them. I have an installer that I trust to do the job right, they have never let me down in the last 20 years. I’ve purchased over 30 hvac units from them for my properties through the years and they will not install anything but Trane. I can attest to Trane’s dependability, as a land lord they are trouble free, never get service calls from renters on these units. I have also used the fact that I have efficient Trane equipement as a selling point. If you having issues with your Trane equipment I would first look to the installer, not the manufacturer. Never go cheap on your installer or you’ll eventually pay.

This was installed six years ago in new construction. It never performed well, the house took long to heat and cool and the temps were uneven around the house. This fall it began operating intermittently and erratically. Note that the warranty is five years. After three tech visits and $400 later it was discovered that the heat exchanger was cracked. Took some work to open it up and use a mirror on an extension rod but I saw the four inch long crack. Luckily it was guaranteed for life (however, $740 in labor to replace) but it is not available for at least a month, maybe more, in the dead of winter in Seattle. The crack in the heat exchanger makes the burner box run too hot, it shuts down after ten min triggering the high limit switch, it also has difficulty starting up because the draft inducer can’t produce the necessary pressure, a condition also created by the cracked heat exchanger. The circuit board is also operating intermittently, giving false signal that the high limit switch is open (four flashes on the diagnostic led on circuit board). The tech says it is a weakness in all Trane products. How about $400 for an upgraded replacement board? The dealer says we can replace the entire unit for $4000. The factory support has been non existent. The Trane web site sucks and they avoid any human contact. I am looking at other brands this week. My Trane Model # tdx1d120a9601ab, serial # 6302hbb7g.

I had this Trane XR90 for ten years. Every part in it has been replaced more than once except the heat exchanger. Now the heat exchanger is leaking gas and carbon monoxide. Learn from my mistake. Buyer beware!
