The Heil HCH9 is a two-stage heat pump with an efficiency rating of up to 19 SEER and 11 HSPF. The two-stage scroll compressor provides optimal temperature and humidity control and is protected by high- and low-pressure switches and a filter drier. Several sound-reducing features, including a variable-speed fan, soft-mount compressor, compressor blanket and Quiet Shift defrost, help keep operating noise as low as 66 decibels. The HCH9 can be paired with an Observer wall control for remote access and intelligent diagnostics. A galvanized steel grille panel cabinet features corner posts for increased durability and a high-gloss baked-on powder coat finish for protection against corrosion and weather hazards.
