The MRCOOL® Signature Series TruInverter™ 60K BTU 230V Multi-Position Air Handler delivers powerful, high-efficiency comfort for large homes and high-demand applications. Using TruInverter™ variable-speed technology, the system continuously adjusts output to match real-time demand, eliminating temperature swings while reducing energy use, noise, and system wear. Built around next-generation R-454B refrigerant, the unit delivers strong heating and cooling performance with a significantly lower environmental impact, helping meet modern efficiency standards while lowering long-term operating costs. The air handler supports upflow, downflow, and horizontal installation, allowing it to fit easily in attics, closets, basements, crawl spaces, or mechanical rooms. Its compact cabinet provides full-capacity airflow without the bulk of older systems. When paired with a compatible MRCOOL® TruInverter™ Heat Pump Condenser, it delivers reliable, high-output comfort in every season. Installation is simplified with MRCOOL® No-Vac® Quick Connect® line sets, which arrive factory-charged with R-454B refrigerant—eliminating vacuum pumps, refrigerant handling, and specialized tools for a faster, cleaner install. The system works with most third-party smart thermostats for flexible, app-based or voice-controlled operation. Optional TruInverter™ electric heat kits provide supplemental or emergency heating in colder climates. Backed by a limited lifetime compressor warranty and a 10-year parts warranty, the TruInverter™ 60K delivers efficient, durable, and future-ready whole-home comfort.
