Roger,
Trane has been mentioned here recently several times in an unfavorable light

Subject: [RFI] Another look at Geothermal H&V
I attended a seminar on GeoThermal H&V yesterday pushing the Trane units.
They use a variable speed fan that sounds like it may be controlled by pulse
width modulation.
I asked if they would guarantee no RFI and the salesman said he'd have to
get back to me. He's coming out Friday to give me a quote, but they know
I'm not interested in even trying it if they can not give me a written
guarantee ahead of time.
It seems like Trane came up on here a while back but I've been unable to
find a reference to it.
