The Standard of Operation
A single-stage unit is either on or off, working at full capacity when in use. With this simplified mode of operation, this product provides the heating and cooling levels you’d expect.
Use Less Energy. Save More Money.
With efficiencies of up to 16.00 SEER2, the EL15KC1 can deliver significant energy savings. In fact, it can help cut your energy bills year-round. It may even help you qualify for energy rebates.
A Peacefully Quiet Environment
To reduce operating sound levels, the EL15KC1 uses a sound-dampening system with a precision-balanced, direct-drive fan to ensure smooth, quiet operation. This lets it operate at a volume as quiet as 72 dB, or the sound of a handheld food mixer.
