• What are advantages of units with variable speed fans?

  • Platinum ZM Heat Pump.jpgVariable speed fans operate on a simple principle: they are able to spin at different speeds depending on the heating and cooling needs of your home. Usually, they operate at lower speeds, delivering a steady, reliable stream of warm or cool air to your home. When conditions become more extreme, the fan speed increases so that the system can meet increased demand, guaranteeing that on even the hottest days or coldest nights, your comfort needs will be met. Older systems simply switch on or off. Newer, variable speed systems lower your utility bills by only using the energy needed to heat or cool your home at any given time.  Consider the AccuComfort™ Variable Speed Platinum 20 from American Standard Air.  It can keep your home within .5 degrees of where you set the thermostat!
