Alliance Mechanical Group

Alliance Mechanical Group operates from 5838 San Fernando Road Unit B in Glendale, California, serving the greater Los Angeles basin with commercial and industrial HVAC, plumbing, and mechanical field services. The contractor holds California license #1015815 with classifications B, C-20, C-36, and C-16, indicating broad licensing across building construction, HVAC, plumbing, and sheet metal disciplines. The company has maintained continuous licensing since 1995, placing it among the longer-operating mechanical contractors in the region. Current rating stands at 3.0 stars derived from two customer reviews, a limited sample that provides limited insight into overall service quality but establishes a baseline for prospective clients to evaluate.

What distinguishes Alliance Mechanical Group from many residential-focused contractors is its deliberate concentration on commercial and industrial projects across diverse sectors. The project portfolio spans restaurants, fast-food chains, retail establishments, multi-family residential buildings, hotels, medical laboratories, hospitals, churches, clean rooms, and computer or electronic manufacturing facilities, plus commercial high-rise structures. This breadth reflects substantial experience navigating varied permitting requirements and building code compliance across multiple industries. The company maintains both workers compensation and general liability insurance, a critical consideration for property managers and business owners undertaking renovation or tenant-improvement projects.

One reviewer documented an air conditioning installation experience that ended with significant frustration, reporting multiple unanswered emails and phone calls regarding warranty or service coverage. The reviewer characterized the contractor as unprofessional and unreliable, noting the company would not respond to requests for follow-up work. This single negative account represents the entirety of publicly available customer feedback, and while two reviews provide insufficient data for statistical conclusions, the communication failure described raises a note of caution for homeowners considering this contractor.
