This is a follow-up comment from my reply a year ago.
My local furnace contractor who has a good reputation came out for our yearly service. A year ago this Sept, the furnace wouldn’t fire because of oxidation in the heat box after one season of heating. The corrosion spot was only the size of a silver dollar, but it was enough the plug the center orfice on one of heaters. This year the corrosion is ten times what is was a year ago – a major concern. The local contractor (installer) took pictures and checked again the intake and exhaust piping to the outside of the house, and deemed it acceptable. Somehow, moisture is getting into the heat box area which is galvanized steel and should be stainless. They were good enough to add a bleed off port and tube on the PVC intake pipe prior to entering the heat box, so that moist air will hopefully be intercepted prior to reaching the heat box. I will keep an eye on this furnace as the third heating season begins. I would not purchase this furnace again in spite of the very good reviews I read about it two short years ago.

Diane,

I had the Trane XV95 installed in October of 2010. I researched numerus furnaces and the Trane was the most expensive, but I did get the Federal Rebate that ended that year. We turned the furnace on on Sept 14, 2011 and the unit didn’t work. The repair man just left, and fixed the problem. We had moisture in the Heat Box (his term) that caused corrosion and plugging of the burner ports. Moisture/water is what killed our last two furnaces, so I’m not very pleased at the moment. The techniciam feels that the water came form the PVC Intake Pipe that draws in outside air. He inspected the pipe on the outside of the house and said they were installed properly and perhaps better (height) than they are required.
I informed the techinician that I would wait a few days and call the salesperson who sold us the unit eleven months ago. I’m giving him time to contact Trane directly to find any history with this problem, and I expect answers from them next week. The heating season has arrived here in Wisconsin, and I’m hoping for a good response.

Chris,
Did you every get a price from Bobby on what he paid for his Trane system? What pricing did you get? I am being quoted a XV95 100,000 BTU furnace with a XL16i A/C unit and Clean Effect filter for $7500. after rebates. Let me know what you have on pricing.
Thanks

Hi Bobby. I was in the market for a new furnace and instalation of a new central air unit. I had an HVAC specialist come to give me a quote and he suggested to same two units that you mentioned (Trane XV95 and the Trane XB14). I was wondering what was the price quote?? Thanks
