MRCOOL Universal 36K BTU R-454B Heat Pump System (3 Ton)

MRCOOL Universal 36K BTU R-454B Heat Pump System

The MRCOOL Universal 36K BTU R-454B Heat Pump System is a complete 3-ton central heating and cooling solution engineered for dependable, year-round comfort and exceptional energy efficiency. This matched system combines a Universal Series Multi-Position Air Handler with a Universal Series DC Inverter Heat Pump Condenser, providing reliable whole-home performance while helping reduce monthly energy costs.

Powered by advanced DC inverter technology, the outdoor condenser continuously adjusts compressor speed to match your home's heating and cooling demands. This delivers quieter operation, improved efficiency, longer equipment life, and more consistent indoor temperatures compared to conventional HVAC systems.

The included multi-position air handler supports upflow, downflow, and horizontal installation, making it an excellent choice for attics, utility closets, crawl spaces, and other ducted HVAC applications. The system is also compatible with the MRCOOL NO-VAC® Quick Connect® Line Set (sold separately), simplifying installation by eliminating vacuuming and flaring. Optional Universal Series Heat Kits provide supplemental and emergency heat for colder climates.
