HVAC Feedback appreciated -

I have a Trane. It was installed in 2007. It is a VERY noisy system. It heats and cools the house, but I don't like it. Installer sucked, salesperson promised the world, the usual bs you get with contractors.

I would do a LOT of research before you go with a Trane. Look into Carrier, for instance.

Everything I've read after I had mine installed and had noise problems said that the design and size of the ductwork has a lot to do with how well it works. Check references!
