I have a quote on a new American Standard System.

Can somebody tell me what these units translate in comparison to models in the Trane line?

3.5 ton 12 seer heat pump
condenser model #2a6h2042a1

3.5 ton variable speed air
handler model # twe040-e

The rep advised the combination of both will give me a total seer rating of 13.0. Is this true?

Aside from the cabinets and logos are there any other differences?

Does one brand tend to run any more expensive than the other?
