Trane Choice 14 Heat Pump
Formerly XR15
The Trane Choice 14 (formerly the XR15) is our recommended value option for Phoenix homeowners who need reliable cooling and heating without premium features. It's a straightforward, single-stage heat pump that does exactly what it's supposed to do - keep your home comfortable - backed by Trane's build quality and our lifetime workmanship warranty.
This system is the entry point to the Trane lineup, and it's a significant step up from budget brands. You still get Trane's Climatuff compressor, Spine Fin coil technology, and the full manufacturer warranty - features that directly translate to longer system life in Arizona's extreme conditions.

Is This the Right System for You?
Ideal For
The Choice 14 is the right system for homeowners who want Trane quality at the most accessible price point. It's ideal for budget-conscious replacements, investment properties, smaller homes, or situations where you want a reliable system without paying for advanced features you may not need.
Consider an Alternative If
If you're sensitive to noise, want precise temperature control, or plan to stay in your home long-term, consider the Priority 17. The two-stage compressor is noticeably quieter and more energy-efficient, which pays back over time through lower utility bills. The Choice 14 runs at full blast whenever it's on - functional but louder and less nuanced.
Pricing & Investment
The Choice 14 is Trane's most affordable split heat pump. Installed pricing varies based on home size (tonnage), installation complexity, and whether you're replacing a matching system or need modifications. We provide free in-home estimates with transparent, upfront pricing - no surprises. Financing is available to make your new system affordable.
Warranty Coverage
The Trane Choice 14 comes with a 10-year limited parts warranty when registered within 60 days of installation by a licensed contractor. As a Trane Comfort Specialist, systems we install are eligible for enhanced warranty coverage. We also provide our own lifetime workmanship warranty on the installation itself.
A2L Refrigerant Transition
Legacy model prefix: 4TWR4
The Choice 14 was previously sold as the XR15 with model numbers starting with 4TWR4 (using R-410A refrigerant). Current models use the 5TWR4 prefix with R-454B refrigerant. If you received a quote for a 4TWR4, that was the R-410A version - the replacement is the 5TWR4 with identical performance using updated refrigerant.
