About Energy ETC, Inc.
Energy ETC, Inc. is a Union City-based building systems contractor holding a 5.0-star rating across two verified reviews. The company specializes in commercial HVAC optimization, serving property managers and facilities professionals throughout the Bay Area. Their core offering centers on Building Management System (BMS) assurance, combining 24/7 remote equipment monitoring with live helpdesk support to keep large commercial HVAC plants operating as designed.
What distinguishes Energy ETC from conventional HVAC contractors is their Connect-Monitor-Correct methodology. Rather than waiting for equipment failures, they proactively connect building systems to cloud-based monitoring, track conditions in real time, and correct problems before they escalate into costly repairs. Their helpdesk operates around the clock, providing immediate technical support without surprise emergency fees. This predictive approach aligns with their stated mission of eliminating tenant disruptions before they impact building operations.
One reviewer, Toby Ludwick, detailed a multi-phase engagement spanning chilled water system optimization, air handler performance tuning, comprehensive retro-commissioning, controller and infrastructure upgrades, and a complex fan system with fire alarm interlock. The work was completed after-hours with minimal tenant impact, described as virtually un-noticed by building occupants. Katherine Doroja specifically praised the team's responsiveness, customer service, and technical knowledge across all interactions.
What Customers Say
Both reviews award five stars, with one reviewer detailing specific project outcomes including retro-commissioning, infrastructure upgrades, and system optimization that reduced utility costs. Responsive service and knowledgeable technicians appear across both testimonials.
