Reduce Fleet Downtime With On-Site Service
For a commercial fleet, the cost of a repair is only one part of the expense.
Downtime can also mean:
• Lost employee hours
• Missed appointments
• Delayed deliveries
• Rental vehicles
• Towing costs
• Reduced productivity
• Lost revenue
When a repair can be performed properly on-site, Kool2U can reduce the time and logistics involved in transporting a work vehicle to a repair facility.
If shop equipment is required, the vehicle can instead be serviced at our San Antonio location.
The objective is to use whichever service method makes the most sense for the repair and the business.
​
Fleet Service for HVAC, Plumbing, Electrical & Contractor Vehicles
Service companies often operate vehicles under demanding conditions.
HVAC technicians, plumbers, electricians and contractors may carry tools, equipment and inventory while driving numerous stops every day.

• Check engine diagnostics

Kool2U helps businesses manage:
• Routine maintenance

• Battery and charging problems
• Cooling systems
• Check engine lights
• Electrical problems
• Heating and A/C systems
• Suspension wear

Fleet service can be coordinated around business needs to help reduce disruption to normal operations.
​
A Diagnostics-First Approach to Fleet Repair
Replacing parts without confirming the cause of a problem can become especially expensive when the same mistake is repeated across several fleet vehicles.
Kool2U's approach is to diagnose the failure before recommending the repair.
That may include:
• Scan-tool analysis
• Live data
• Bidirectional testing
• Oscilloscope testing
• Current-ramp testing
• Thermal imaging
• Electrical circuit testing
• Mechanical testing
• Manufacturer service information
This same advanced diagnostic capability is available to commercial customers as it is to individual vehicle owners.
