Commercial Ductless Heat Pump (DHP)

Commercial Ductless Heat Pump (DHP) logo
Ductless Heat Pumps are optimized for use in buildings without ductwork. They use variable-speed compressors to continuously match the heating and cooling load, avoiding the on/off cycling of conventional heating systems that result in fluctuating temperatures and high energy consumption.
  • Easy, low-cost installation
  • Improved indoor air quality
  • Quiet operation
  • Reduced energy costs

Incentive Information

All new ductless heat pumps (DHP) must have an AHRI certificate.

Replace existing electric resistance heat with:
•    Any DHP < 10.4 HSPF2 or < 11.0 HSPF: $1,000 per ton
•    Non-ducted DHP, minimum 10.4 HSPF2 or 11.0 HSPF: $1,300 per ton
•    Ducted or mixed DHP, minimum 9.4 HSPF2 or 10.0 HSPF: $1,300 per ton

Replace existing non-electric resistance heat with:
•    Any DHP < 10.4 HSPF2 or < 11.0 HSPF: Not eligible for a rebate
•    Non-ducted DHP, minimum 10.4 HSPF2 or 11.0 HSPF: $300 per ton
•    Ducted or mixed DHP, minimum 9.4 HSPF2 or 10.0 HSPF: $300 per ton

Requirements
1. You must be an active Cowlitz PUD customer served by a non-residential rate. To be eligible for an incentive, your account must be in good standing. Cowlitz PUD reserves the right to withhold incentive funds and apply to past-due account balance.

2. This incentive is available for retrofits and upgrades to existing buildings only.

3. Pre-conditions for a 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. A failed heat pump system operating with electric-resistance back-up heat is not considered electric-resistance for the purposes of meeting pre-condition requirements.

4. Pre-conditions for a DHP upgrade: The space is conditioned by an operational or failed DHP or air-source heat pump; or the space is part of a building addition, new construction, or major renovation project.

5. The new ductless heat pump must have an AHRI certificate of product rating documenting the DHP outdoor condenser meets BPA’s efficiency requirements below:
• Non-ducted systems: 10.4 HSPF2 or 11.0 HSPF
• Ducted or mixed systems: 9.4 HSPF2 or 10.0 HSPF

6. This incentive is not available for packaged terminal air conditioning unit (PTAC) retrofits.

7. Program requirements and available incentives are subject to change without prior notice.
Steps to Participate
1. Contact Cowlitz PUD Energy Efficiency Services to confirm eligibility prior to starting the project.

2. Upon project completion, submit the following items to Cowlitz PUD: A completed Ductless Heat Pump (DHP) – Retrofits and Upgrades Project Information Form, the AHRI certificate, and a copy of the installation contractor’s invoice, including the manufacturer and model number of the equipment installed.

3. Cowlitz PUD will verify the project meets program requirements. The incentive will be processed once verification is complete, and a check will be mailed within eight weeks of approval.
