Commercial Ductless Heat Pump

Rebate amounts and program requirements are subject to change without notice. All homes or businesses are subject to inspection and usage data analyzed by participating in energy efficiency programs. Any rebates will be applied to past due amounts owed CPI before payment is issued.

Ductless Heat Pumps (DHPs, also commonly referred to as mini-splits) save energy using variable speed compressors to continuously match the heating and cooling load and avoid the on/off cycling of conventional heating systems. DHPs eliminate over-cooling and over-heating of spaces that is common with central air systems. By moving heat instead of creating it, DHPs are two to three times more efficient than electric-resistance heaters.

A DHP Retrofit replaces the existing zonal or forced-air electric-resistance heating system with a DHP.

A DHP Upgrade either: 1) replaces an existing DHP with a more efficient DHP (e.g., replacing a code minimum DHP); or 2) is an efficient DHP installed as part of a building addition project, new construction project or major renovation project.

Requirements and Specifications

  • These measures cannot be used to retrofit packaged terminal air conditioning (PTAC) units.

Preconditions – DHP Retrofit:

  • The space is conditioned by zonal or forced-air, electric-resistance heat as the primary heating source.No other heating sources are eligible.

Preconditions – DHP Upgrade:

  • The space is conditioned by an operational or failed DHP; or
  • The space is part of a building addition, new construction, or major renovation project


  • The installed DHP must be listed on the DHP Qualified Products List; and
  • The DHP outdoor condenser must meet BPA’s efficiency requirements per the table below.
  • A minimum 11 HSPF 11.
  • The incentive form and invoices must be completed and submitted to CPI.


DHP Upgrade: $300 per ton
DHP Retrofit: $1,000 per ton
