Description

The MRCOOL® 2nd Generation Universal® Series 36K Inverter Packaged Heat Pump is designed to deliver dependable heating and cooling while lowering energy costs and environmental impact.
Built with advanced DC inverter technology, the compressor runs at variable speeds to match your home’s exact needs, maintaining steady comfort without the frequent system cycling seen in older systems. This reduces wear on components, improves efficiency, and helps the unit operate at a whisper-quiet frequency.
With an impressive 18 SEER2 rating, this packaged system significantly reduces energy consumption while still providing strong airflow and performance. It is engineered to handle extreme climates, delivering reliable heating in temperatures as low as –22°F (–30°C) and cooling in conditions as high as 125°F (52°C). No matter the season, homeowners can count on consistent comfort and efficiency.
Environmentally conscious design is another advantage. The Universal® 36K uses R-32 refrigerant, a modern, lower-GWP alternative that reduces environmental impact compared to traditional refrigerants. This makes it a sustainable and forward-thinking choice for today’s homeowners.
Installation is simplified with a versatile multi-position design that supports vertical upflow/downflow and horizontal configurations.
Built for durability, the MRCOOL® Universal® Series 36K is backed by a 10-year parts and labor warranty, giving homeowners confidence in long-term performance. It’s a smart investment in comfort, savings, and sustainability.
