Trane Priority 15 Package Heat Pump
The Trane Priority 15 package heat pump is the higher-efficiency option in Trane's package heat pump lineup. With a two-stage compressor, it delivers better comfort and lower energy bills than the single-stage Choice 14 while maintaining the convenience of an all-in-one outdoor installation.
The two-stage operation means the system runs at a lower, quieter speed most of the time and only ramps to full capacity on the hottest days. If your home requires a package unit and you want the best available comfort, the Priority 15 is the premium choice.

Is This the Right System for You?
Ideal For
The Priority 15 is the right choice when you need a package unit and want the best comfort and efficiency available in this form factor. If you're replacing an existing package system and plan to stay in the home, the two-stage upgrade is worth the modest premium over the Choice 14.
Consider an Alternative If
If your home can accommodate a split system, even a mid-tier split heat pump like the Priority 17 will outperform this package unit in efficiency and comfort. Package units are best when space constraints make them the only practical option.
