Like other iQ Drive units, this model includes an inverter-driven rotary compressor for efficient, quiet operation. The unit can meet the cooling demands of the home by modulating between 49-118 percent capacity in five steps. The unit also operates at noise levels as low as 59 dBA. This model is compatible with most two-stage thermostats and does not require a shielded thermostat cable. Also, this unit includes an all-aluminum microchannel coil for increased corrosion resistance, heat transfer, and reliability.
