What We Do

Reefer units installed, repaired and maintained.

We keep refrigerated trucks running cold — from the compressor to the cargo door. Whether you need a brand-new unit, an emergency repair or a scheduled PM program, OATAS has the bays, tools and experience to protect your load.

New Reefer Unit Installation

We size, source and install transport refrigeration units on 12 to 26 foot box trucks, straight trucks, vans and custom bodies — single-temp or multi-temp zones, with or without electric standby shore power. Every install covers mounting and roof sealing, wiring and controls, refrigerant charge, insulation and bulkhead work, then a full pull-down test at your target temperature before the truck leaves, documented for food-safety and DOT records.

Refrigeration Repair & Diagnostics

From compressor failures and refrigerant leaks to electrical faults and sensor alarms, we diagnose the root cause instead of guessing. We repair Carrier, Thermo King, Zanotti and most major reefer brands with OEM or quality-approved parts.

Preventive Maintenance Programs

Scheduled PM keeps your cold chain intact and your warranty valid. We inspect belts, hoses, refrigerant levels, condensers, evaporators, door seals and temperature loggers — then document everything for food-safety and compliance records.

Mobile Refrigeration Service

A down reefer means spoiled cargo. Our mobile team handles roadside diagnostics, jump-starts, electrical repairs and temporary cooling solutions across Cleveland, Akron, Canton and the surrounding Northeast Ohio counties.
