A&B Mechanical is a Union based, licensed and bonded contractor. Our company was founded over a decade ago but the key managers have all been in the HVAC industry for in excess of 20 years – all within the Bay Area. In a sentence, we understand the needs of companies and organizations that call the Bay Area home. Knowledge of Northern California industries and how the different climate zones impact heating, cooling, and refrigeration requirements make us an excellent design, service, and installation partner.

As a company, we also give back to the industry by supporting our key managers in their off hours roles as teachers in local union training programs. A&B only employs highly trained, experienced, union employees and the company has years of experience in all commercial and industrial HVAC/R applications whether the need be design, installation, or maintenance. Our mechanics are on call 24/7 and 365 days a year through our after-hours dispatching service so we can fully support our customers with critical systems.

We proudly stand behind our work and strive to keep your equipment in top condition through proper installation and maintenance programs tailored to your business needs.

We are centrally located in Downtown Livermore Ca.
