Commercial Fleet Services
From scheduled PMs to roadside breakdowns, our mobile diesel mechanics handle commercial truck repair for high-utilization fleets, regional carriers and terminal operations across Chicagoland and Will County.

PM-A, PM-B and PM-C service at your terminal or staging yard during off-hours and weekend dwell time. No deadhead miles, no driver shop hours.

24/7 Mobile Diesel Repair
Rapid-dispatch mobile units with diagnostics, welding and commercial parts inventory to fix roadside breakdowns on site, day or night.

Mobile DPF Regeneration & Emissions
Forced DPF regens and emissions diagnostics for Cummins, Detroit, PACCAR and Volvo engines, done on site so a clogged filter doesnโt mean a tow.

Diagnostic & Electrical Repair
ECM / TCM health scans, battery and alternator testing, starter repair and ABS wiring diagnostics for heavy-duty powertrain and chassis electrical systems.

Air Brake, Suspension & Air Systems
Inspection, rebuilds and emergency repair of air brake chambers, valves, lines and governors, plus wheel ends, steering linkage and trailer air suspension.

Heavy welding capability on every mobile unit for roadside and yard repairs, plus emergency hose swaps to stop leaks and get trucks moving again.

Trailer Repair & Maintenance
Structural PMs for dry vans, reefers and flatbeds: landing gear, door roll and seal, floors, crossmembers, lighting, wiring and brakes.

DOT Inspection & Compliance
Annual DOT inspections and pre-DOT audits that catch out-of-service violations early, with FMCSA / DOT BIT records kept audit-ready.
Built to Eliminate Downtime
Across the Chicagoland freight basins, unbilled driver hours, roadside breakdowns and out-of-service DOT violations cut straight into your operating margins.
ENCINA POWER brings yard maintenance to your terminal during off-hours and weekend dwell time. No deadhead miles to a shop, no drivers waiting on the clock and no unnecessary towing fees.
Unbilled Driver Downtime
Drivers sitting in a shop lobby on the clock instead of running loads.

Brake, lighting and tire defects that park a truck at a roadside inspection.
