Description
The MRCOOL TruInverter MCAEAMPVT36D21BA is the 3-ton multi-position air handler matched to the TruInverter variable-speed heat pump. Its DC blower and electronic expansion valve work with the inverter condenser to deliver 1150 CFM of quiet, precisely controlled airflow. Optional TruInverter heat kits (5kW, 10kW, 15kW) add supplemental heat.
The MRCOOL® Signature Series TruInverter™ 36K BTU 230V Multi-Position Air Handler is designed to deliver powerful, energy-efficient comfort for homes and light-duty applications. Built with advanced TruInverter™ variable-speed technology, this system continuously adjusts output to match real-time demand, maintaining precise indoor temperatures while using significantly less energy than traditional fixed-speed systems.
The result is quieter operation, smoother performance, and lower monthly energy costs.At the core of the system is next-generation R-454B refrigerant, which provides excellent heat transfer while dramatically reducing environmental impact. This modern refrigerant helps lower global warming potential while ensuring compliance with current and future efficiency regulations.Installation flexibility is a major advantage.
The air handler supports upflow, downflow, and horizontal configurations, making it ideal for attics, crawl spaces, closets, and mechanical rooms. Its slim, compact design fits where bulky air handlers cannot.
When paired with a compatible TruInverter™ outdoor heat pump condenser, the system delivers efficient heating and cooling in all seasons.Setup is faster and cleaner thanks to compatibility with MRCOOL® No-Vac® Quick Connect® line sets, which arrive factory-charged with R-454B refrigerant.
This eliminates vacuum pumps, refrigerant handling, and specialized HVAC tools, reducing labor and installation risk.The air handler works with most third-party smart thermostats, giving you freedom to choose your preferred control platform.
Optional TruInverter™ electric heat kits provide added heating support for cold climates or backup operation.Backed by a limited lifetime compressor warranty and a 10-year parts warranty, the MRCOOL® TruInverter™ 36K delivers efficient, flexible, and long-lasting comfort you can depend on.
