It started as one refrigeration shop in Portland with a name stitched from its two founders. Seventy years later it moves heat pumps, compressors and thermostats through 450-plus branches - and the contractors who buy from it once owned the whole thing.
Bedrock Energy
Bedrock Energy is an Austin-based geothermal startup making heating and cooling for commercial buildings cheaper and cleaner. By reengineering oil-and-gas drilling technology with real-time subsurface sensing and simulation software, Bedrock drills geothermal boreholes up to 5x faster, then designs and delivers ground-source heat pump systems that can cut a building's HVAC energy costs in half while slashing related air pollution.
Dandelion Energy
Dandelion Energy is an Alphabet (Google X) spinout that designs, installs, and finances residential and multifamily geothermal heating and cooling systems. By drilling ground loops that tap the earth's stable temperature and pairing them with a proprietary heat pump, Dandelion replaces fossil-fuel furnaces and air conditioners with a single all-electric system that cuts home heating and cooling bills while eliminating on-site emissions. The company has grown into the largest home geothermal provider in the U.S., installing thousands of systems and partnering with the nation's largest production homebuilders and multifamily developers to make geothermal a default option for new construction.
