Bay Area Service Hub Review

Licensed since 2019 (operating as GDM Group, dba TRIO Heating Air Plumbing & Electrical) after rebranding from Pacific Air USA, this San Jose-based contractor holds an unusually broad B/C-10/C-20/C-36 license and specializes in heat-pump conversions, gas-to-electric electrification, installs, and repairs across the greater Bay Area. Reviews are strongly positive on communication, on-time arrival, no-pressure options-based selling, and transparent flat ('Set-In-Stone') pricing, with the multi-trade license letting them self-perform the electrical and plumbing that conversions require rather than subbing it out. Best for homeowners doing heat-pump/electrification work or wanting fast, communicative service who value upfront flat quotes.

Essential Q&A

What makes this contractor stand out?
A rare four-classification license (General Building, Electrical, HVAC, Plumbing) lets them self-perform the panel work and plumbing that heat-pump and electrification conversions require, paired with standout communication and no-pressure, options-based selling.
Who should hire this contractor?
Homeowners doing heat-pump or gas-to-electric conversions, or anyone wanting fast, well-communicated HVAC service who values transparent flat-rate quotes over the lowest possible bid.
Insider tip
Get the written 'Set-In-Stone' flat quote before work starts, and for installs confirm the permit is pulled and the city inspection passes — given a documented pre-rebrand code/callback issue, insist on the post-install inspection and ask for a specific well-reviewed technician by name.
