Why reefer repair is different
A reefer unit keeps a load cold or frozen. When it fails, the clock is running on the cargo, not just the truck. A trailer of food or medicine sitting in the sun with a dead unit is an emergency that can cost far more than the repair. That urgency shapes everything about a reefer repair business: dispatch speed, after-hours coverage, parts on the truck and clear communication with the customer.
Reefer work also mixes skills: diesel engines that drive many units, refrigeration systems, electrical and controls, and the trailer or truck itself. See MetaFleet for reefer repair.
Refrigerant certification
U.S. EPA regulations under Section 608 of the Clean Air Act, at 40 CFR Part 82, Subpart F, require that technicians who maintain, service, repair or dispose of equipment that could release ozone-depleting refrigerants into the atmosphere be certified. EPA describes the types of certification and the approved certification programs. Check with EPA guidance and your certifying organization which certification applies to the units your technicians work on, and keep copies of each technician's certification on file. Refrigerant handling rules also cover venting, recovery equipment and records, so read EPA's Section 608 pages in full.
Services to offer
- Road calls for units that fail in transit.
- Yard calls at distribution centers and drop yards.
- Pre-trip and pre-season checks.
- Scheduled maintenance on the unit's engine and refrigeration system. See preventive maintenance interval and engine hours.
- Diagnostics and controls work.
- Trailer repairs such as doors, seals, lights and brakes, if you have the skills.
Many reefer units track their own engine hours, which makes hour-based maintenance schedules practical.
Mobile, shop or both
Mobile work goes to the unit, which saves the load. A shop is useful for bigger repairs, overhauls and work that needs a controlled space. Many reefer businesses do both. Decide which you will lead with, and make sure your dispatch and invoicing handle both kinds of job. See field service.
Treat loaded units as urgent
When a call comes in, ask first whether the unit is loaded, what the cargo is, and what temperature it needs. That decides priority. Capture the unit number, trailer number, location, unit make and model, and the alarm or fault the driver sees. A dispatcher who knows a loaded trailer is waiting will move it ahead of an empty one. See how to dispatch mobile diesel technicians.
Parts on the truck
Reefer road calls often fail on a part the technician does not carry. Stock common parts on each service truck based on the units you see most, and track what is on each truck. See service truck inventory and special order part.
Records
Fleets that run reefers want records by unit: what failed, what was done, parts used, engine hours, and any refrigerant work. Motor carriers must keep inspection, repair and maintenance records for vehicles they control under 49 CFR 396.3, and your invoices and repair lines often become part of those records. Keep refrigerant records as EPA rules require. See how to write a repair line with the 3 Cs.
Pricing
Reefer pricing usually combines:
- A service call fee and travel or mileage.
- Labor at your labor rate.
- Parts with markup.
- Refrigerant and recovery charges.
- An after-hours rate.
Quote before you roll, and get approval before work grows. See how to send estimates customers approve.
Fleet accounts
Refrigerated carriers, food distributors and grocery fleets need reliable reefer service. They value fast response, after-hours coverage, records by unit and clean invoices. Offer scheduled maintenance as well as road calls, and they will call you first when a unit fails. See how to win fleet maintenance contracts.
After-hours coverage
Loads move day and night. Decide who is on call, how calls reach them, and what rates apply. Tell callers the after-hours rate before you roll, and consider a card hold for new customers. See after-hours rates for mobile mechanics.
Choosing which units to service
Reefer units come from several makers, and each has its own controls, parts and diagnostic tools. Many new businesses start with the makers they know best and the fleets nearby run, then add others as they hire and train. Being honest with a caller about which units you can fix is better than rolling and failing.
Getting paid
Reefer road calls for unknown carriers carry payment risk. Take a card hold or payment by link for new customers, and bill fleets on agreed terms with a monthly statement. Send the invoice from the job the same day, with clear repair lines and parts. See truck repair invoice: what to include.
Technicians
Reefer technicians need refrigeration, diesel and electrical skills, plus the right certification. Hiring is hard, so training matters. Pair new technicians with experienced ones on calls, and keep notes from past jobs where the whole team can see them.
Pre-season work
Every fleet has its own busy season. A unit checked before that season is less likely to surprise anyone in transit. Offer pre-season checks in a slower period, scheduled at the yard, and use them to build fleet relationships. A pre-season visit can cover a look at the engine, belts, filters, refrigeration performance, controls and alarms, and the trailer's doors and seals, based on the unit maker's guidance and the fleet's own forms.
Communicating with the customer
A reefer customer is often thinking about the load more than the unit. Keep them updated: when the technician is on the way, when they are on site, what was found, and when the unit is cooling again. Send the estimate for approval by link so work is not held up on a callback. If the unit cannot be fixed on site, tell them quickly so they can arrange to move the load.
Equipment for reefer work
Beyond general diesel tools, reefer technicians usually need refrigerant recovery equipment, gauges, leak detection tools and diagnostic tools for the unit makers they service. EPA's Section 608 rules include requirements for recovery equipment, so check them before buying. Keep equipment on each service truck tracked like parts, so you know who has what.
Example: a loaded reefer road call
Example only. This illustration does not describe any specific shop.
A driver calls at night: the reefer on a loaded trailer is showing an alarm and the box temperature is rising. The dispatcher records the call, marks it urgent because the trailer is loaded, and offers it to the on-call technician with reefer skills who is closest and has common parts on the truck. The customer gets the after-hours rate up front and a card hold is placed. The technician finds the fault, sends an estimate the driver's company approves by link, fixes it, and records the repair lines, parts and engine hours. The invoice goes out before the technician leaves.
Common mistakes
- Treating a loaded reefer call like any other road call.
- Rolling without the common parts.
- Losing track of technician certifications.
- Weak records by unit.
- Invoicing days after the call.
How MetaFleet helps
MetaFleet runs mobile and in-shop diesel and heavy-equipment repair, including reefer work. Calls are recorded and become jobs, dispatch ranks technicians on skills, availability and drive time, technicians write shorthand that becomes repair lines with suggested hours, preventive maintenance can track engine hours, and invoices go out with a pay link.
