Trane Premier 20 Heat Pump
Formerly XV20i
The Trane Premier 20 (formerly the XV20i) is the absolute top of Trane's residential heat pump lineup. It shares the same variable-speed Climatuff compressor technology as the Premier 18 but pushes efficiency ratings even higher with an enhanced refrigerant circuit design.
We install the Premier 20 and it's an exceptional system. However, we want to be straightforward: for most homeowners, the Premier 18 delivers nearly identical real-world comfort at a lower price point. The additional efficiency of the Premier 20 typically saves $100-150 per year in energy costs - meaningful, but the payback period on the price premium is long.

Is This the Right System for You?
Ideal For
The Premier 20 makes sense for homeowners who want the absolute highest efficiency available, plan to stay in their home for 10+ years, and value having the premium tier of any product they buy. It's also the right choice for very large homes where the cumulative energy savings are magnified, or for homeowners who are committed to minimizing their environmental footprint.
Consider an Alternative If
For most homeowners, the Premier 18 delivers 95% of the comfort and efficiency at a meaningfully lower price. The additional $100-150 per year in energy savings from the Premier 20 over the Premier 18 means a long payback period on the price difference. Unless maximum efficiency is your primary goal regardless of ROI, the Premier 18 is typically the better value in the premium tier.
