The 20-SEER FS4BG iQ Drive air conditioner joins the other models in the iQ Drive product line and offers highly efficient, quiet performance. It is available in 2-, 3-, 4-, and 5-ton capacities. iQ Drive products include an inverter-driven rotary compressor to exactly meet a home’s demands. This particular model modulates between 49 percent and 118 percent of capacity. The FS4BG air conditioner features simple installation and includes an all-aluminum microchannel coil. The unit is compatible with most two-stage thermostats, and it does not require a shielded thermostat cable. The microchannel coil results in superior corrosion resistance, optimized heat transfer, and increased reliability.
