Ductless Heat Pumps

Warm up to savings

Ductless heat pumps provide heating and cooling to homes with no, or poorly operating, ductwork. Often referred to as a “mini split,” it consists of one outdoor heat exchanger unit and up to two separate, or “split,” units mounted on the interior wall.

Ductless heat pumps operate without ductwork, eliminating potential loss of energy from leaky or unsealed ducts, making your home more energy efficient and lowering energy costs.

Ductless heat pump benefits

  • Effective in low temperatures. Ductless heat pumps provide consistent heat when outside temperatures drop to 14°F or lower. 
  • Quiet, comfort and control. Ductless heat pumps are quiet and compact, and can heat or cool individual rooms or zones—each controlled by its own thermostat. 
  • Better air quality. Ductless heat pumps have a built-in air filter, which can improve air quality in homes without ductwork. 
  • Save energy and money. Ductless heat pumps can cut heating costs by up to 40 percent, when compared to a standard electric furnace or electric baseboard heater.
  • Easy installation. Ductless heat pumps use no connecting ductwork, resulting in easier installation and less disruption in your home.

Energy Trust offers an $800 cash incentive per residence. The incentive is limited to a maximum of one incentive per home and is available to offset the cost of one outdoor unit and one indoor unit installed per home. Additional indoor or outdoor units are unlikely to produce significant additional energy savings and are not eligible for additional Energy Trust incentives. Customers who install more than one outdoor unit and/or more than one indoor unit must submit Form 300DHP along with their incentive application.

To qualify for this incentive:

  • Residence must use electric resistance heat (examples include: baseboards, ceiling and wall heat or electric forced-air furnaces) as the primary heat source
  • The ductless heat pump replaces the electric resistance heat in the main area of the home* 
  • Unit must be inverter-driven with a minimum five-year warranty
  • Ductless heat pump line sets—the pipes that transfer coolant between the outdoor and indoor units and are wrapped with insulation to prevent heat loss—must be enclosed by the line set cover. To prevent insulation deterioration from the sun, Energy Trust recommends wrapping the insulation with UV tape.
  • Unit must be installed by a contractor who is trained by the manufacturer on the specific heat pump brand, and who attended a NW Ductless Heat Pump Project orientation webinar. View a list of qualified contractors

*Please note: newly built homes, new additions, homes with existing heat pumps, boilers or gas furnaces do not qualify for this incentive.
