To support the growth and effectiveness of heat pump installer networks (HPINs) in the Northeast, this report reviews HVAC-oriented energy efficiency contractor networks and HPINs in the region, including evaluation of interviews with a subset of programs. The analysis identifies best practices for program administrators that are considering establishing an HPIN or evolving an existing network to better accommodate cold climate air source heat pumps (ccASHPs). Successful HPINs typically have a tailored design and implementation strategy closely aligned with program and policy objectives. The research and interviews informing this guide suggest five key best practice areas relevant to any HPIN:
- Emphasize heat pump system sizing and design in required training
- Prioritize flexible continuing education offerings that highlight emerging innovations and best practices
- Provide continuous learning and accountability through meaningful quality assessment and quality control procedures
- Foster a community of opportunity and recognition to make contractor participation worthwhile
- Adapt programs and networks to local conditions but identify opportunities to align standards across the region
