The company also assists homeowners with navigating rebates, financing options, and tax credits available for energy efficiency upgrades.

Reviewers describe specific experiences with the team that illuminate their service quality. One San Francisco homeowner recounting a 2022 installation mentioned technicians David, Beto, and Homero coordinated duct work modifications to resolve comfort issues in a mid-century living room that previously relied on fireplace supplemental heat. Another reviewer praised David Hamburger for arriving personally despite a packed schedule to repair a furnace failure the week before Christmas, preventing a stranded pet from facing a freezing home. A Burlingame client noted the team coordinated smoothly with an electrical contractor to install a 220V line for a new heat pump water heater.
