Typically that design in the condenser panels (long circular holes for air thru the condenser fins) are Chinese made.

So 'assembled in Texas' really doesn't mean much.

It's interesting to note tho' that this equipment doesn't require any registration, you just install it and go.

However, a few gotchya's --- it is entry level equipment only AFAIK. 13 and 14 SEER in Air Conditioners. It appears it's more for home builder's than anything else.... because home builders rarely register the equipment.

10 years parts: Indoor / outdoor coils, Compressor

20 years parts: heat exchanger

5 year parts: motors, start up components etc.

You need a licensed HVAC contractor to get / exchange parts. (No DIY)

Replacement motors from Trane are typically quite expensive so hard to say what their angle is in this, other than being more competitive in the builder's market.

There's other rules / requirements above this but nothing new really. If you don't keep the installation invoice the start up date is moved to 60 days beyond the date stamp in the serial number to which the equipment was made.

So say you use a contractor who bought a bunch of this equipment, sat around in a warehouse for years.... 'start up' installation paperwork becomes quite important.
