Compare a refrigeration unit's technical features with service actually available in your region. Ask for written coverage rather than a marketing description.

Use failure records to list location, first notification, technician arrival, repair and parts waiting time. If records are missing, keep that gap visible in your decision.

Ask providers which locations and hours they cover, and how critical-part availability is confirmed.

Compare responses with contract terms for attendance, interim remedies and charges. Request records of service actually delivered too.

Change the number of fleet brands only after your own records show the training, parts and service burden.

Assess maker warranty, dealer service and independent repair support as separate items.

If considering a spare container or unit, check which failure and delivery scenarios it would cover using lost-trip records.

If service coverage on your routes is unclear, include that uncertainty and need for written confirmation in the purchase decision.
