Hi, I'm in final stages of building a new home and finally got the builder and his HVAC contractor to agree to upgrading my HVAC system (base unit trane builder grade AC 13 seer, and Trane XL90 gas unit - no heat pump) to include heat pump and higher efficient units (all energy star).
So now I need to make my decision quickly between two final components (the heat pump model). I'm debating between the XL15i and the XL16i.
Can any of you provide some input and feedback on either of these models and recommend which model to go with. I think the one major difference is that the XL16i is dual stage (whatever that means).
Here's the other components that will be consistent:
I will be maintaining the gas as the aux heat fuel, but will be upgrade to the XV90 (variable speed) model instead of the XL90.
Any feedback will be helpful.
