About Matrix HG Inc
Matrix HG Inc operates from Novato, California, as a commercial-focused HVAC and building solutions provider holding California contractor license #812232. The company maintains a 5.0-star rating from a single verified client review and serves the Greater San Francisco Bay Area, including Novato and surrounding communities. With over two decades in operation, Matrix HG has completed more than 35,000 jobs while building relationships with over 2,500 client accounts. The company operates around the clock with 24-hour emergency availability seven days per week.
What distinguishes Matrix HG from many regional contractors is the scale of operations and breadth of in-house capabilities. The company maintains affiliations with multiple United Association trade unions including UA 38, UA 159, UA 342, UA 343, UA 393, UA 467, and UA 469, indicating access to a trained workforce. Their service portfolio spans chiller maintenance, direct digital controls engineering, sustainable systems design, and custom fabrication, allowing integrated project delivery from pre-construction through final installation. This combination of technical expertise and trade union affiliation positions them for complex commercial retrofits and new construction projects.
Given limited public review data available, specific customer scenarios cannot be verified. The company emphasizes relationship-focused service delivery and maintains 24/7 availability for emergency response across their commercial client base in the Bay Area.
What Customers Say
With only one client review on record, statistical generalizations are not possible. The single review awarded a 5-star rating, but insufficient data exists to identify patterns in customer sentiment or service experience.
