PTCS Heat Pump Program

Contractors who are certified for the Bonneville Power Administration’s Performance Tested Comfort Systems (PTCS) heat pump program are welcome to apply to Cowlitz PUD’s program. There is a requirement to complete at least two (2) PTCS installations each year and maintain a performance bond on file with Cowlitz PUD. Only PTCS certified contractors currently on the Cowlitz PUD list are eligible to offer rebates for heat pump installations.

Ductless Heat Pump

Contractors who are participating in the Comfort Ready Home Program through the Bonneville Power Administration (BPA) are eligible to install and offer rebates for Cowlitz PUD customers. Contractors are responsible for pulling permits and may not defer permits to their customers. Contractors wishing to offer an “instant rebate” to their customer, shall request the customer’s signature on the rebate form. If this option is chosen by the customer, the contractor must show the discount on the customer invoice after sales tax is applied. Contractors can complete the rebate form, attach a copy of the AHRI certificate and final invoice, and submit it to Cowlitz PUD.

Insulation & Window Courtesy Contractors

Contractors who are interested in installing insulation and windows can offer rebates to Cowlitz PUD customers. However, it is not a requirement to be on the Cowlitz PUD Courtesy Contractor List.  Any contractor who is licensed/bonded with the Washington State Department of Labor and Industries is eligible. We ask that contractors successfully complete five projects before we will add your company information to our Courtesy List. Insulation and window rebates must be pre-approved.

Smart Thermostats

Cowlitz PUD offers rebates for Smart thermostats for customers who heat with electric forced-air furnaces and heat pumps. Contractor-installed Smart thermostats qualify for a $165 rebate; customer-installed thermostats qualify for a $140 rebate. Provide a copy of your receipt with a completed rebate form.

Heat Pump Water Heaters

Cowlitz PUD offers a $600 rebate for heat pump water heaters when replacing an existing electric storage-tank water heater because they use approximately 65-70% less electricity. They can be installed by a licensed contractor or by a homeowner. Provide a copy of your receipt with a completed rebate form.

Ductless Heat pumps (DHPs)

Contractors participating in the NW Ductless Program are eligible to install and offer rebates for Commercial Ductless Heat Pumps for Cowlitz PUD commercial customers.

Cowlitz PUD offers a rebate of $1,000/ton for retrofit installations (converting from electric-resistance heat to a heat pump).  The rebate is $150/ton for HVAC upgrades (replacing an old heat pump with a new heat pump).
