As one of the largest HVAC service and maintenance contractors in California, FSI handles approximately 1000 service requests each month in addition to performing routine preventative maintenance on over 600 commercial maintenance accounts.

Our service program guarantees a two-hour response time to all requests throughout the state. But, not just anybody shows up – consistency is critical.

Our crews are comprised of skilled, long-term employees, ensuring that when service is needed, the technicians who perform repairs or maintenance will be knowledgeable about your building or facility, and can get right to work performing needed tasks.

Because our service teams are stationed across California, they are expert at serving the different regions and the varied climate and geography that impacts each client’s unique HVAC needs.
