year-round peak

Dual-purpose heating and cooling; peak kWh in January-February and July-August.

Ways to cut the cost

  • 1

    Set thermostat to 'heat pump' mode — not 'emergency heat' — except in true cold snaps

    Aux strip heat is 2-3x more expensive to run

  • 2

    Keep outdoor unit clear of debris and 18+ inches of snow

    Blocked airflow forces defrost cycles that waste 15-20% energy

  • 3

    Replace filters every 60-90 days

    Maintains as-designed heat transfer; dirty filters cut output 10%
