Comfort Features
A single-stage air conditioner is the most basic model, with airflow on or off. A two-stage model offers high- and low-stage cooling as conditions require and therefore can provide enhanced comfort levels. Variable-speed AC systems include premium comfort features such as multiple stages for more precise temperature control and more consistent comfort.
Sound Performance
Air conditioners with variable and multi-stage compressors provide ultra-quiet operation compared to models with single-stage compressors. In addition, models that include sound blankets and our Silencer System II™ design can further reduce noise levels. If your AC unit is located near a bedroom window or patio, for example, sound performance might be an important feature to consider.
Energy Savings
Air conditioners are rated by their seasonal energy efficiency ratio (SEER2). The SEER2 rating of an air conditioner is much like miles per gallon (MPG) for a car: The higher the SEER2 rating, the more energy efficient the system.
Humidity Control
Reducing the humidity levels within your home can dramatically improve your comfort and indoor air quality. To help cool your home, your AC unit pulls heat and humidity out of indoor air, using your system’s blower to circulate the air. Models with a variable-speed compressor provide excellent humidity control because they can operate at lower speeds for longer times. So, they spend more time pulling humidity out of the air than models with a two-stage or single-stage compressor.
