We wanted to do energy efficiency upgrades, but didn’t know where to start or what we needed. David helped us put together a long-term plan and figured out what we needed. They put in wall insulation, redid the attic insulation, removed our gas furnace and air conditioner in the garage and installed a heat pump in the attic, and installed a heat pump water heater. At some point we’ll have them get our crawl space in order too. We are finally on the verge of being 100% electric and removing our gas line! He teams handles all the permits and rebates, and has been patient through all of out delays with PG&E. I don’t know anything about this stuff, but the building inspectors have been impressed with both the equipment and the installation work, so I take that as a good sign!
