Guide
The GWP heat pump rebate helps eligible Glendale homeowners replace qualifying heating and cooling equipment. However, the amount depends on the existing system, new equipment, and program requirements.
Glendale Water & Power offers residential rebates for eligible customers. First, the property must receive service from GWP. Then, the installed equipment must meet the applicable program requirements.
Qualifying heat pumps must meet current ENERGY STAR standards and the program’s efficiency requirements. GWP also requires an AHRI certificate documenting the equipment combination. Because eligibility depends on specific equipment, confirm the requirements before purchasing.
GWP offers $1,000 per ton when an eligible customer replaces gas or gas/electric HVAC with qualifying electric heat pump equipment. The maximum rebate is $5,000. This tier also covers qualifying ENERGY STAR mini-split heat pumps.
For example, a qualifying three-ton system would correspond to a $3,000 rebate before other program limitations. However, GWP reviews eligibility and the supporting documentation. A finalized Building & Safety mechanical permit is required for this rebate.
Homeowners who already use a heat pump may qualify for a different incentive. GWP offers $500 per ton for eligible heat pump replacements. The maximum rebate under this tier is $2,500.
The new system must meet the program’s ENERGY STAR and efficiency requirements. Also, GWP requires an AHRI certificate for the equipment. The program provides this rebate as a utility bill credit.
Some heat pump installations require additional electrical capacity. So, homeowners may need to consider a panel upgrade during project planning. However, not every home needs one.
GWP offers a $1,000 rebate for eligible electrical panel upgrades paired with qualifying heat pump installations. This includes qualifying heat pump HVAC and heat pump water heater projects. A finalized electrical permit is required for the panel incentive.
First, confirm that your GWP account and residential property meet the program requirements. Next, verify the equipment’s ENERGY STAR qualifications and obtain the AHRI certificate. Also, collect the required purchase documentation and applicable finalized permits.
Submit the application through the GWP rebate process within 12 months of the purchase date. The deadline runs from purchase, not the date you begin researching equipment. Because funding and program terms can change, review GWP’s current instructions before applying.
