Make the estimate more accurate

  • Base hours on the damp season if use is seasonal.
  • Clean the filter and allow airflow.
  • A continuous drain prevents interruptions but does not directly reduce power.

Presets are estimates. Use your model label, an EnergyGuide annual-kWh figure or a safe meter reading when available. Compare old and new appliance payback.
