The MRCOOL® Signature Series TruInverter™ 48K BTU 230V Multi-Position Air Handler delivers powerful, energy-efficient comfort for homes. Built with TruInverter™ variable-speed technology, it continuously adjusts output to match real-time demand, providing smooth, consistent temperatures while reducing energy use, system wear, and operating noise.
Using next-generation R-454B refrigerant, the system offers excellent heat transfer with a much lower environmental impact, helping meet modern efficiency standards while lowering long-term operating costs.
The air handler supports upflow, downflow, and horizontal installation, fitting easily in attics, closets, crawl spaces, or mechanical rooms. When paired with a compatible TruInverterâ„¢ Heat Pump Condenser, it provides reliable heating and cooling in every season.
Installation is faster and cleaner thanks to MRCOOL® No-Vac® Quick Connect® line sets, which arrive factory-charged with R-454B refrigerant, eliminating the need for vacuum pumps or refrigerant handling. The system works with most third-party smart thermostats, and optional TruInverter™ electric heat kits add supplemental or emergency heat for cold climates.
Backed by a 10-year parts warranty, the TruInverterâ„¢ 48K delivers efficient, flexible, and dependable whole-home comfort.
