Shovels Empowers Carbon Free Homes: Achieving 100% Installation Targets with Our Contractor Matching Platform


Carbon Free Homes faced significant difficulties in connecting homeowners with qualified contractors for the installation of heat pumps, water heaters, and other climate-friendly appliances.

Despite a growing awareness and demand among homeowners for such technologies, the availability of trustworthy contractors who are capable, willing, and ready to take on these projects was limited. The traditional methods of finding these contractors were inefficient and often led to unreliable data that hindered scalability and effectiveness.


To address this challenge, Carbon Free Homes turned to Shovels, a comprehensive and filterable database drawn from over 100 million building permit applications nationwide, updated monthly. Shovels provides detailed, high-quality data that includes the type of permit filed, the date of filing, and the profile and contact information of the contractor.

This solution enabled Carbon Free Homes to efficiently connect homeowners with reputable contractors, significantly reducing the time and effort required to sift through data manually.


The collaboration with Shovels led to remarkable outcomes for Carbon Free Homes:

  • Achieved 100% of the target numbers for pilot installations of heat pumps, water heaters, and induction stoves in San Anselmo and Fairfax, Marin County, CA.
  • Streamlined the process of contractor matching, which was previously a major bottleneck, enhancing customer satisfaction and trust in the marketplace.
  • Facilitated a group buy program that provided homeowners within a service area access to more competitive bids and seamless installation processes.

This efficient system not only improved the rate of successful installations but also supported the expansion of Carbon Free Homes' service offerings, including the launch of their Collaboration Energy group buying platform.
