## Description

The MRCOOL Signature Series 18K Heat Pump System combines a high-efficiency condenser with a versatile multi-position air handler for reliable, year-round comfort. The condenser delivers up to 14.3 SEER2 and 11.7 EER2 efficiency and comes factory pre-charged with low-GWP R-454B refrigerant for simplified installation and compliance with modern standards. Features include a single-speed scroll compressor, inner-groove copper tubing, copper "A" coils with aluminum fins, intelligent defrost control, and built-in sensors for consistent, reliable operation. The air handler supports upflow, downflow, or horizontal installation in attics, closets, crawl spaces, and other tight areas, with a galvanized steel cabinet, insulated interior, and protective coil guard for durability. Operating around 60 dB, it ensures quiet performance while the PSC blower motor provides steady airflow. The system is compatible with most smart thermostats, includes a built-in filter rack, and offers optional electric heat kits for supplemental warmth. Backed by a 10-year limited parts warranty and limited lifetime compressor warranty, this Signature Series 18K bundle delivers efficient, flexible, and long-lasting comfort for residential spaces.
