Signature 2.5 Ton up to 14.3 SEER2 30,000 BTU Split System Heat Pump
The MRCOOL® Signature Series 30k Heat Pump Condenser delivers reliable, energy-efficient performance year-round. With ratings of 14.3 SEER2 and 11.7 EER2, it offers consistent heating and cooling while helping homeowners manage energy costs in every season. Whether battling intense summer heat or chilly winter air, this system is built to maintain a comfortable indoor environment. The unit comes pre-charged with R-454B refrigerant, a low-GWP alternative that aligns with current environmental standards. This refrigerant reduces environmental impact without compromising performance. The pre-charged design speeds up installation, reducing both time and labor expenses. At the heart of the system is a rugged single-speed scroll compressor that ensures steady, efficient operation. Inner-groove copper tubing enhances heat transfer, while integrated pressure and temperature sensors protect against extreme conditions. An intelligent defrost function maintains reliable performance in cold weather by preventing frost buildup. Despite its powerful capabilities, the Signature Series 30k runs quietly at just 63 decibels. A sound-dampening top helps keep operational noise to a minimum, making it suitable for residential areas. For added durability, the exterior features a steel louver coil guard and wire fan discharge grille for extra protection. With sweat connection service valves and an easy-access gauge port, installation and maintenance are simple. Backed by a 10-year limited parts warranty and a limited lifetime compressor warranty, it’s a dependable investment in long-term home comfort.
