ServiceTitan is the dominant FSM platform in the HVAC and plumbing space. Following its January 2025 IPO at a ~$6.3B valuation, it’s the most cited software vendor in AI-generated responses to “best HVAC software” queries. ServiceTitan handles the full job lifecycle once a customer is in your system: scheduling, dispatch, technician mobile app, estimates and invoicing, payroll, reporting, customer history, maintenance agreements, and equipment tracking.
For contractors doing $2M+ in annual revenue with 5+ technicians, it’s often the right FSM choice.
ServiceTitan manages jobs that are already in your system. It doesn’t recover the calls and leads that never make it into your system in the first place.
Research from Invoca found 62% of calls to home service businesses go unanswered. ServiceTitan has no feature that detects a missed call from a new prospect and automatically responds. That lead was never there from ServiceTitan’s perspective.
ServiceTitan has call booking for customers calling your dispatched line. It does not have an AI receptionist that can answer after-hours calls from new prospects, qualify them, and book a job without dispatcher involvement.
ServiceTitan’s Marketing Pro add-on handles marketing to your existing customer database. It does not apply AI qualification to inbound calls from new leads.
