About this product

The MRCOOL® Universal® Series 36K DC Inverter Heat Pump Condenser is designed to deliver dependable, high-efficiency heating and cooling—even in the most extreme weather conditions. Whether you're facing sweltering summer heat or freezing winter temperatures, this unit ensures steady, year-round comfort. With an impressive 18 SEER2 efficiency rating, it offers substantial energy savings without compromising performance, making it an ideal replacement for outdated, energy-hungry systems. Engineered for flexibility and convenience, the 36K Universal® condenser features a compact footprint that allows for installation in space-constrained areas. Its smaller size makes it an excellent fit for homes with limited outdoor clearance while still delivering powerful, whole-home comfort. Installation is quick and hassle-free—especially when paired with the optional MRCOOL® NO-VAC® Quick Connect® line set (sold separately). This innovative, pre-charged line set eliminates the need for traditional vacuuming, flaring, or refrigerant handling, reducing installation time, labor costs, and complexity. At the heart of the system is advanced DC inverter technology, which allows the compressor to continuously modulate output based on your home’s real-time temperature demands. Unlike traditional systems that cycle on and off, this inverter-driven condenser maintains more consistent temperatures, reduces power consumption, minimizes component wear, and keeps noise levels to a minimum. Whether you're upgrading an aging system or installing a new HVAC solution, the MRCOOL® Universal® Series 36K Heat Pump Condenser offers a winning combination of efficiency, performance, and quiet operation. To ensure long-lasting confidence, it’s backed by a 10-year parts warranty and a 2-year limited labor warranty.
