  • Unfortunately: We no longer produce this particular iQ Drive air conditioner. However, you can check out our other iQ Drive air conditioner, the FS4BG, for an alternative, ultra-efficient option.
  • Quiet Operation: This iQ Drive air conditioner operates at some of the industry's lowest sound levels — all the way down to 59 decibels.
  • Dehumidification Mode: Because of this air conditioner's iQ Drive technology, it can run longer at lower levels. This provides additional dehumidification assistance and increased home comfort.

The efficiency levels achieved by the FS4BI are truly outstanding. The technology employed in this smart unit is award winning. In fact, it has been voted a top choice by a leading consumer magazine.
