BUYING GUIDE
Reefer unit hours, temperature pull-down, insulation, and CARB compliance — the checks that protect a reefer purchase.
A used reefer trailer inspection should cover the refrigeration unit hours, a temperature pull-down test, insulation condition, CARB compliance, frame, floor, doors, brakes, and tires. Sell My Rig Inspections performs all of these in a same-day reefer inspection for $350 flat, with reefer diagnostics and 200+ photos.
Record the unit make, model, and hours. Reefer units like Thermo King and Carrier have expected service lives measured in hours — high hours mean a major rebuild may be near.
The inspector runs the unit and verifies it reaches and holds set point. Slow pull-down points to a refrigerant, compressor, or insulation problem.
Check the walls and floor for delamination, water intrusion, and damage. Failing insulation forces the unit to work harder and shortens its life.
In California and several other states, reefer units must meet CARB rules. Verify the unit is compliant before you buy if you will operate in those markets.
Standard trailer checks still apply: brake lining, tread depth, suspension, and frame condition.
It depends on the unit, but many buyers budget for a major service around 12,000-15,000 hours. The inspection records actual hours and unit condition so you can plan.
