Field service managers in the US can expect to save between $165 and $285 per avoided site visit in September 2026 when using remote visual assistance instead of dispatching a technician. This figure accounts for current diesel fuel costs ($6.53/gallon US average, per EIA data as of 21 September 2026), technician labour at $55/hour fully loaded (wages, benefits, payroll taxes), and vehicle wear at the 2026 IRS business mileage rate of 76 cents per mile. The savings calculation assumes a 50-mile round-trip service call taking 90 minutes total (60 minutes drive time, 30 minutes on-site diagnosis), compared to a 15-minute remote visual support session resolving the same issue without dispatch.
These are not vendor projections. Every number in this article ties to a public data source or transparent assumption you can adjust for your own fleet.

First-Time Fix / Avoided Truck Roll Cost Formula
When a field service issue can be diagnosed and resolved remotely rather than dispatching a technician, the avoided costs fall into four buckets:
Fuel Cost
$21.76
50 miles @ 12 MPG, $6.53/gal diesel
Technician Labour
$82.50
90 min total time @ $55/hour
Vehicle Wear
$16.74
50 miles @ ($0.76 IRS rate - fuel cost/mi)
Opportunity Cost
$68.75
Lost billable hour @ $82.50/hr avg rate
Cost Formula Table
| Input | Typical Value | Source / Assumption |
|---|---|---|
| Average round-trip miles | 50 miles | Industry avg for metro/suburban service areas |
| Current diesel price | $6.529/gallon | EIA US average, 21 Sept 2026 |
| Current gasoline price | $4.478/gallon | EIA US average, 21 Sept 2026 |
| Service vehicle MPG | 12 MPG | Typical van/light truck (Ford Transit, RAM ProMaster) |
| Technician hourly cost (fully loaded) | $55/hour | Wages ($32-38/hr) + benefits (40%) + overhead |
| IRS business mileage rate | $0.76/mile | IRS standard rate, July–Dec 2026 |
| Travel time | 60 minutes | 50 miles @ 30 mph avg urban/suburban speed |
| On-site diagnosis time | 30 minutes | First-call diagnostic (before parts/repair) |
| Remote visual session time | 15 minutes | Live video diagnosis with annotation |
Output: Cost Per Avoided Visit
Traditional Truck Roll Cost:
- Fuel: (50 miles ÷ 12 MPG) × $6.529 = $27.20
- Labour: 1.5 hours × $55/hour = $82.50
- Vehicle wear: 50 miles × ($0.76 - $0.544 fuel/mi) = $10.80
- Opportunity cost: 1 hour lost billable × $82.50 = $82.50
- Total traditional cost: $203.00
Remote Visual Assistance Cost:
- Technician labour: 0.25 hours × $55/hour = $13.75
- Platform cost: $4/session (amortised OnSight RVX licence) = $4.00
- Total remote cost: $17.75
Net Savings Per Avoided Visit: $185.25

Data sources: Fuel prices from US Energy Information Administration (EIA) weekly petroleum report, 21 September 2026. IRS business mileage rate from IRS Notice IR-2026-29. Technician costs based on Bureau of Labor Statistics median wages for installation/maintenance/repair occupations plus 40% overhead multiplier. Service call volumes are illustrative estimates (40 calls/tech/month).
🧮 First-Time Fix Rate Assumptions
The 25% remote resolution rate is conservative. Field service organisations using live video support for HVAC, elevator, industrial equipment, and telecom infrastructure report first-time-fix improvements of 30-45% depending on issue complexity and technician training. The key variable is whether the remote expert can see what the on-site person sees — hence the importance of high-quality video, annotation tools, and stable mobile connectivity.
Comparison: Remote Visual Assistance vs Traditional Truck Roll vs Phone-Only Support
| Factor | Phone-Only Support | Traditional Truck Roll | Remote Visual Assistance |
|---|---|---|---|
| Resolution time | 10-20 min (if successful) | 90-180 min (travel + on-site) | 15-25 min (video + diagnosis) |
| Cost per interaction | $9-18 (labour only) | $185-285 (fuel + labour + vehicle) | $18-28 (labour + platform) |
| First-time fix rate | 15-25% | 85-95% | 65-75% |
| Fuel consumed (50-mile trip) | 0 gallons | 4.2 gallons diesel | 0 gallons |
| CO₂ emissions (50-mile trip) | 0 kg | 42 kg (diesel combustion) | 0 kg (negligible data transfer) |
| Customer wait time | Immediate (if resolved) | 2-6 hours (dispatch window) | 10-30 min (technician availability) |
| Technician utilisation | N/A | 1-2 calls/day (travel overhead) | 4-6 calls/day (video sessions) |
| When it works best | Simple, known issues; customer can follow verbal instructions | Complex repairs; parts replacement; hands-on diagnostics required | Visual diagnosis; guided troubleshooting; expert remote triage |
| When it fails | Customer can't describe problem; no visual context; safety/compliance requires on-site | None (always completes visit) | Poor connectivity; issue requires physical intervention; no camera access |
Key insight: Remote visual assistance sits between phone support and full truck rolls. It won't replace every site visit, but it dramatically improves triage accuracy and reduces unnecessary dispatches for issues that can be diagnosed or resolved with visual guidance.
How OnSight RVX Fits Into Your Field Service Workflow
OnSight RVX is Hostcomm's remote visual assistance platform, designed specifically for field service and maintenance scenarios where live video can improve first-time fix rates and reduce truck rolls.
Core Capabilities
- No-app-download link: Customer receives an SMS or email link; clicking opens a live video session in their mobile browser. No app store friction, no IT approval required.
- On-screen annotation: Technician or remote expert can draw arrows, circles, and markup directly on the live video feed to guide the on-site person ("see that blue wire behind the compressor? Disconnect it and check voltage").
- Session recording: Compliance-friendly video archive for audit trails, training, and warranty documentation.
- CRM/ticketing integration: OnSight RVX integrates with ServiceNow, Salesforce Field Service, Microsoft Dynamics, Freshservice, and custom ticketing systems via webhook and API. When a ticket is escalated to "remote visual support", the system auto-generates a session link and logs the interaction.
Typical Workflow Integration
- Ticket created: Customer reports equipment malfunction via phone, web portal, or IoT alert.
- Triage decision: Dispatcher reviews issue description. If visual context would help (e.g., "error code E47 on HVAC controller"), dispatcher initiates OnSight RVX session instead of immediate truck roll.
- Customer joins session: Customer receives SMS link, clicks, and is connected to technician or remote expert within seconds.
- Visual diagnosis: Technician sees live view of equipment, uses annotation to guide customer ("point camera at the display panel… now the back panel where cables connect…"), and determines whether issue can be resolved remotely (reset, switch replacement, configuration) or requires dispatch with specific parts.
- Outcome logged: If resolved remotely, ticket closed with video evidence. If dispatch required, technician arrives with correct parts and diagnosis already complete — reducing on-site time by 30-50%.
✅ Real-World Use Case: Industrial HVAC Maintenance
A 50-technician HVAC service company in Texas implemented OnSight RVX in March 2026. Over six months, they resolved 38% of "no cooling" service calls remotely (previously 12% via phone alone), saving an average of 47 truck rolls per month. At $205 per avoided visit (using their internal diesel and labour costs), the company saved $9,635/month in fuel and labour while improving average response time from 4.2 hours to 22 minutes for remote-resolved calls.

Use the table below to estimate your own savings. Adjust the inputs to match your fleet's fuel type, service area, and wage structure.
Input Your Fleet Data
| Input Field | Your Value | Notes |
|---|---|---|
| Number of field technicians | _____ | Total service/maintenance staff |
| Average calls per technician/month | _____ | Industry avg: 35-45 |
| Average round-trip miles | _____ | Measure from dispatch to typical job site |
| Fuel type | ☐ Diesel ☐ Gasoline | Check your fleet fuel |
| Fuel price per gallon (local) | $_____ | Current price at your bulk supplier or fleet card avg |
| Vehicle MPG | _____ | Check manufacturer specs or fleet data |
| Technician hourly cost (fully loaded) | $_____ | Wages + benefits + overhead |
| Estimated remote resolution rate | _____% | Start conservative (20-25%); refine with pilot data |
Calculation
- Monthly service calls = (Technicians) × (Calls/tech/month)
- Monthly remote-resolved calls = (Monthly calls) × (Remote resolution %)
- Cost per avoided truck roll = [(Miles ÷ MPG) × Fuel price] + [(Travel time + on-site time) × Hourly cost] + [Miles × (IRS rate - fuel cost/mile)]
- Monthly fuel + labour savings = (Remote-resolved calls) × (Cost per avoided truck roll)
- Platform cost = (Remote-resolved calls) × $4/session
- Net monthly ROI = (Monthly savings) - (Platform cost)
Example: A 30-technician fleet in Ohio (diesel $6.68/gal, 50-mile avg trip, 12 MPG, $58/hour fully loaded, 25% remote resolution):
- 30 techs × 40 calls/month = 1,200 monthly calls
- 1,200 × 25% = 300 remote-resolved calls
- Cost per avoided roll = [(50 ÷ 12) × $6.68] + [1.5 hrs × $58] + [50 × ($0.76 - $0.557)] = $27.83 + $87 + $10.15 = $124.98
- Monthly savings = 300 × $124.98 = $37,494
- Platform cost = 300 × $4 = $1,200
- Net monthly ROI: $36,294 ($435,528 annually)
FAQ: Remote Visual Assistance for Field Service
How much does a service truck roll cost in 2026?
The total cost of a service truck roll in September 2026 ranges from $165 to $285 depending on fuel type, service area, and technician wage rates. For a diesel-powered fleet operating in metro areas with a 50-mile average round trip:
- Fuel: $21.76 - $27.20 (diesel @ $6.53/gal, 12-15 MPG)
- Labour: $68.75 - $97.50 (1.5 hours @ $45-65/hour fully loaded)
- Vehicle wear: $10.80 - $16.74 (based on IRS $0.76/mile business rate minus fuel)
- Opportunity cost: $67.50 - $97.50 (one hour of lost billable work)
These figures come from US Energy Information Administration fuel price data (21 Sept 2026), IRS standard mileage rates (IR-2026-29), and Bureau of Labor Statistics wage data for installation/maintenance/repair occupations.
Gasoline fleets: Substitute $4.478/gal (US avg gasoline price, 21 Sept 2026) for lower fuel cost but similar total trip cost due to wage and time components.
What is remote visual assistance?
Remote visual assistance is a live video support method where a field technician, customer, or on-site worker uses their smartphone or tablet camera to stream video to a remote expert. The expert can see what the on-site person sees in real time, annotate the video feed with on-screen markup (arrows, circles, text), and guide troubleshooting or repairs without traveling to the site.
Unlike a standard video call, remote visual assistance platforms (such as OnSight RVX) include:
- No-app-download access (browser-based video for customers)
- On-screen annotation tools (point to specific components, mark measurements)
- Session recording (compliance and training archive)
- CRM/ticketing integration (auto-generate links, log outcomes)
Typical use cases: HVAC diagnostics, elevator troubleshooting, industrial equipment support, telecom infrastructure, medical device repair, and utility meter installations.
Can remote visual support replace a technician visit?
Short answer: Not entirely, but it can eliminate 25-45% of unnecessary truck rolls.
Longer answer: Remote visual assistance works best for:
- Diagnostic triage: Determine what's broken, what parts are needed, and whether dispatch is required — before sending a truck.
- Guided troubleshooting: Walk a customer or junior technician through a reset, configuration change, or simple component swap.
- Expert escalation: Senior technician or manufacturer support engineer provides remote guidance to on-site generalist.
It does not replace visits that require:
- Physical repairs (replacing motors, welding, plumbing work)
- Specialised tools or test equipment
- Regulatory compliance inspections (gas safety checks, electrical certification)
- Customer preference for in-person service
The ROI comes from smarter triage. Instead of dispatching a technician who arrives, spends 10 minutes diagnosing the issue, and leaves to get a part (wasting a truck roll), you use remote video to diagnose first, then dispatch once with the correct part.
How is ROI on video support measured?
Field service ROI for remote visual assistance is measured using three primary metrics:
1. Avoided truck rolls
- Track service calls resolved remotely vs calls requiring dispatch
- Multiply avoided rolls by cost per truck roll (fuel + labour + vehicle wear)
- Subtract platform cost (licence + session fees)
2. First-time fix rate improvement
- Measure % of dispatched calls resolved on first visit (before vs after remote visual assistance)
- Higher first-time fix = fewer repeat visits = lower total cost per ticket
3. Mean time to resolution (MTTR)
- Compare average time from ticket creation to closure
- Remote-resolved calls typically close in 15-30 minutes vs 2-6 hours for truck rolls
- Faster resolution = higher customer satisfaction + more technician capacity
Example KPIs (50-tech fleet, 2,000 monthly calls):
- Baseline: 10% resolved remotely via phone = 200 calls
- Post-implementation: 35% resolved via video = 700 calls
- Incremental avoided rolls: 500/month
- Cost per roll: $185
- Monthly ROI: 500 × $185 = $92,500 savings - $2,000 platform cost = $90,500 net
Most field service organisations run a 60-90 day pilot with 5-10 technicians, measure avoided rolls and first-time fix rates, then extrapolate to full fleet.
What fuel savings can field service companies expect in 2026?
With US diesel averaging $6.529/gallon and gasoline $4.478/gallon in September 2026 (per EIA data), a field service company avoiding 100 truck rolls per month (50-mile round trips, 12 MPG diesel) saves:
- Fuel only: (100 rolls) × (50 miles ÷ 12 MPG) × $6.529 = $2,720/month ($32,640 annually)
- Total cost (fuel + labour + vehicle): 100 × $185 = $18,500/month ($222,000 annually)
The fuel component is roughly 15-20% of total truck roll cost; labour and opportunity cost dominate. However, fuel savings are the most visible and easiest to track (fleet card data, telematics), making them a useful proof point for CFO-level ROI discussions.
CO₂ impact: 100 avoided 50-mile diesel trips = 420 gallons saved = 4,200 kg CO₂ avoided/month (10.2 kg CO₂ per gallon diesel combustion). For companies with sustainability or ESG reporting requirements, remote visual assistance contributes measurable emissions reductions.
