Hello:

Am about to invite contractors in for quotes on replacing our present
30 yr old gas, forced hot air heating system.

Consensus seems to be, I believe, after a lot of reading, that American
Standard and Trane offer the highest quality these days.

I always thought that they were the same company, with the same furnaces,
but labeled differently.

Are there any meaningful differences between the two brands ?
What in particular, etc.

Thanks,
Bob
