The new Climasure heat pump offers a 13-plus SEER rating and a heating season performance factor up to nine. When matched with a compatible variable-speed air handler or gas furnace from this company, the heat pump can achieve efficiency levels above 14 SEER and up to 9.5 HSPF, officials say. The Climasure 13-SEER heat pump operates under lower refrigerant pressures. The unit features a demand-defrost system that cycles the unit into defrost mode only when needed, reducing wear and tear, officials add. A high-pressure relief valve and solid-core filter drier help to extend the life of the compressor. A raised fan-coil guard protects from impact and reduces sound, according to the company. The heat pump is backed by a five-year warranty on parts and a five-year limited warranty on the compressor.
