Product Description MRCOOL® Signature Series 36K 3-Ton Cooling-Only AC Condenser (230V) The MRCOOL® Signature Series 36K (3-Ton) Air Conditioner Condenser is designed for homeowners who need strong, dependable cooling for larger living spaces while keeping operating costs under control. Whether you’re replacing an aging AC system or installing new equipment, this cooling-only condenser delivers reliable performance during the hottest months of the year. With an efficiency rating of 14.3 SEER2 and 11.7 EER2, this unit provides consistent, energy-conscious cooling without sacrificing comfort. It ships factory pre-charged with R-454B refrigerant, a next-generation, low-GWP refrigerant that meets modern environmental standards. The factory charge also helps reduce installation time and labor costs. At the core of the system is a durable single-speed scroll compressor, a proven design known for long service life and steady operation. Inner-groove copper tubing improves heat transfer efficiency, allowing the system to cool more evenly and respond quickly to temperature changes. Integrated pressure and temperature sensors help protect the system during demanding conditions. Despite its larger capacity, the unit operates at just 63 dBA, making it quiet enough for residential neighborhoods. A sound-control top, along with a steel louvered coil guard and wire fan discharge grille, helps reduce noise, protect internal components, and extend the life of the condenser. Designed to pair with MRCOOL® Signature Series multi-position or stud-mount air handlers, this cooling-only condenser is backed by a 10-year limited parts warranty and a limited lifetime compressor warranty, giving homeowners long-term confidence in their investment. If you’re looking for powerful cooling, quiet operation, and proven reliability, the MRCOOL Signature Series 36K AC condenser is a smart choice for larger homes.
