MRCOOL Universal 36K BTU Inverter Packaged Heat Pump – Model MDPH18036D
The MRCOOL Universal® 36K BTU DC Inverter Packaged Heat Pump (MDPH18036D) provides powerful heating and cooling in a compact, energy-efficient HVAC system designed for dependable year-round comfort. Featuring advanced DC inverter compressor technology, this system adjusts its output in real time to match your home’s exact heating and cooling needs.
Unlike traditional HVAC systems that constantly turn on and off, the inverter-driven compressor operates at variable speeds to maintain steady indoor temperatures. This reduces energy consumption, minimizes mechanical wear, and allows the system to run more quietly while delivering consistent airflow and comfort throughout the home.
With an impressive 18 SEER2 efficiency rating, the MRCOOL Universal 3-ton packaged heat pump significantly lowers energy costs while maintaining reliable performance. It is engineered to perform in demanding climates, providing dependable heating in temperatures as low as –22°F and cooling capability in outdoor conditions up to 125°F.
This system utilizes R-32 refrigerant, a next-generation refrigerant with a lower Global Warming Potential compared to older refrigerants. The result is improved environmental sustainability and compliance with modern HVAC efficiency standards.
Installation flexibility makes the Universal Series ideal for both replacement systems and new HVAC installations. The unit supports horizontal, vertical upflow, and downflow configurations, allowing HVAC professionals to adapt the system to a wide range of residential layouts.
Designed for durability and long-term reliability, the MRCOOL Universal packaged heat pump is backed by a 10-year parts and labor warranty, giving homeowners peace of mind and dependable performance for years to come.
