Founded in 2001, Sandium began as an installer of heating and air conditioning systems. Prior to that, we collaborated with a major manufacturing company, TRANE, contributing to the development of cutting-edge building analysis tools, comfort system controls, and commercial building performance contracting.
As a full-service HVAC company, we offer design, engineering, and installation services for heating & air conditioning systems, zone systems, high-efficiency water heaters, Home Performance contracting, energy auditing, and ventilation/air filtration services.
Sandium proudly holds multiple licenses, including C-20 (Warm-Air Heating, Ventilating and Air-Conditioning), C-2 (Insulation and Acoustical), and B (General Building Contractor).
Our bonded and insured team takes the time to listen to your specific needs, gathering essential data to provide custom solutions with holistic home energy, air quality, and comfort in mind – no cookie-cutter solutions here.
We actively participate in major rebate and incentive programs to pass along value and savings to our clients, managing all processes in-house for a seamless experience.
Each project is led by a skilled technician who manages the process from start to finish. Our factory-trained teams have deep expertise in Bay Area HVAC, ensuring respectful, courteous, and confident workmanship. Safety is paramount, and our teams undergo mandatory safety training twice a month to guarantee job-site safety.
To stand behind our quality, we offer a 100% Satisfaction Guarantee, as we believe in the excellence of our services.
