Your fleet is your second-biggest expense after labor. Trucks, fuel, insurance, maintenance — it adds up to $12,000-$18,000 per vehicle per year. Yet most HVAC companies manage their fleet with… nothing. No tracking, no maintenance schedule, no fuel optimization.
Here’s when you need fleet management software and which tools make sense.
Do You Actually Need Fleet Software?
Under 5 vehicles: No. Use your FSM’s GPS for dispatch visibility and a spreadsheet for maintenance reminders (oil change every 5,000 miles, brake inspection every 15,000). Total cost: $0.
5-10 vehicles: Maybe. If fuel costs are rising, vehicles are breaking down frequently, or you suspect unauthorized use, basic fleet tracking helps. Your FSM’s GPS might still suffice.
10+ vehicles: Yes. At this scale, 10-15% fuel savings from route optimization = $200-$400/month. Preventive maintenance scheduling prevents $3,000-$5,000 breakdowns. Driver behavior monitoring reduces accident liability. The math works.
Top Fleet Management Platforms
Samsara ($30-$50/vehicle/month)
Best overall fleet management for service companies
Samsara is the market leader for good reason. Real-time GPS, AI dashcam, engine diagnostics, fuel tracking, maintenance scheduling, driver safety scoring, and compliance management. The dashboard gives you a complete picture of every vehicle’s status, location, and health.
The AI dashcam deserves special mention: it records driving and automatically flags safety events (hard braking, distracted driving, near-collisions). This protects your company from liability and identifies training opportunities.
Best for: 15+ vehicle fleets that want comprehensive fleet intelligence.
Verizon Connect ($25-$45/vehicle/month)
Strong alternative with good reporting
Verizon Connect offers similar features to Samsara with strong reporting and analytics. Fleet utilization reports, idling analysis, and geofencing (alerts when vehicles enter/leave defined areas) are well-implemented.
Best for: Fleets that prioritize reporting and analytics.
GPS Trackit ($20-$35/vehicle/month)
Budget fleet tracking
Core GPS tracking, route history, speed alerts, and basic maintenance reminders at a lower price point. Doesn’t have dashcams or advanced diagnostics, but covers the essentials.
Best for: 10-20 vehicle fleets wanting basic tracking without premium pricing.
Azuga ($25-$35/vehicle/month)
Driver-friendly approach
Azuga gamifies safe driving with a rewards program. Drivers earn points for good behavior (smooth braking, no speeding, minimal idling) and can redeem for prizes. This positive reinforcement approach works better than surveillance for many teams.
Best for: Companies wanting to improve driver behavior through incentives rather than penalties.
Key Features That Save Money
Fuel Optimization
Fleet software identifies fuel waste: excessive idling, inefficient routing, speeding (which burns more fuel). Reducing idle time alone saves $30-$50/vehicle/month for the typical service fleet. If you’re exploring this area, our Best Marketing Software for Home Service Companies guide covers it in detail.
Preventive Maintenance
Track mileage and engine hours per vehicle. Get alerts for oil changes, brake inspections, tire rotations, and other scheduled maintenance. Preventive maintenance extends vehicle life and prevents expensive roadside breakdowns.
A missed oil change doesn’t cost $80. It costs $8,000 when the engine seizes on the highway with $5,000 in parts on the truck.
Unauthorized Use Detection
Geofencing alerts you when vehicles leave the service area or are used after hours. Some contractors discover that vehicles are being used for personal errands, side jobs, or are parked in strange places. Fleet tracking eliminates unauthorized use.

Accident Documentation
Dashcam footage and GPS data provide evidence in accident disputes. When a customer claims your driver hit their mailbox, GPS data showing the vehicle was never on that street settles it instantly. This has saved contractors thousands in false claims.
Fleet Management Without Dedicated Software
If dedicated fleet software doesn’t fit your budget, here’s a manual approach:
Maintenance Tracking
Create a spreadsheet per vehicle:
- Current mileage
- Last oil change (date + mileage)
- Last brake inspection
- Last tire rotation
- Last transmission service
- Any known issues
- Next scheduled maintenance
Review weekly. Send reminders to techs. This takes 30 minutes per week for a 10-vehicle fleet.
Fuel Tracking
Require techs to log fuel purchases (many gas cards track this automatically). Review monthly for anomalies — a truck that’s using 20% more fuel than similar vehicles might have a maintenance issue or an inefficient driver.
Mileage Monitoring
Have techs report odometer readings weekly. Track mileage per vehicle to plan replacements (most service vans should be replaced at 150,000-200,000 miles) and ensure maintenance schedules are followed.
Vehicle Replacement Planning
Fleet software helps you plan vehicle replacements based on data:
- Total cost of ownership: Track all costs per vehicle (fuel, maintenance, insurance) and identify which vehicles are becoming money pits
- Mileage tracking: Plan replacements before vehicles enter the high-maintenance zone
- Depreciation curves: Replace vehicles at the optimal point where maintenance costs start exceeding depreciation savings
A well-managed fleet replacement cycle (replacing vehicles every 5-7 years or 150K-200K miles) reduces total fleet costs by 10-20% compared to reactive replacement (fixing vehicles until they die).
Bottom Line
Under 10 vehicles: FSM GPS + maintenance spreadsheet. Over 10 vehicles: dedicated fleet management (Samsara, Verizon Connect, or GPS Trackit). The investment in fleet software pays for itself through fuel savings, preventive maintenance, and reduced liability. We break this down further in Best Field Service Management Software in 2026.
Your trucks are on the road 250+ days per year. Managing them proactively is as important as managing your technicians. Both are assets that generate revenue — treat them accordingly.
