Advanced modulating technology in the new LX Series 16 SEER/9.0 HSPF heat pump contributes to more even temperatures and lower operating costs. Adjust its operating capacity for quiet, efficient operation to provide only what is actually needed to condition the space. Reducing compressor speed and decreasing airflow allows the system to operate longer without drastically over-cooling the space, improving dehumidification. In colder weather, a demand defrost feature minimizes heat pump operation. Features: Durable powder painted steel coil guards protect against corrosion and coil damage; balanced, direct-drive fan minimizes vibration and sound; coils optimized for efficient airflow and effective refrigerant circulation for optimal heat transfer; easy access to commonly serviced items; a sturdy fan guard; smooth edges for easier handling; and a compact footprint for easy hand trucking and placement on site. Fee-free, one-year labor limited warranty.
