Walk-In Cooler & Freezer Repair in Raleigh, Durham & Chapel Hill
Repair, Diagnosis & Preventative Maintenance
Boer Brothers repairs and maintains walk-in coolers and walk-in freezers for restaurants and commercial kitchens across the Triangle, from the door and panels to the evaporator, condensing unit, and controls. Our rates are published, there’s no trip charge, and billing starts at dispatch. If the box can’t hold temperature during the repair, we can deliver a cooler trailer to your back door, same day in most areas, pending availability. Technicians are available 8 AM to 9 PM weekdays and 9 AM to 9 PM weekends. We’ve worked out of our Chapel Hill shop since 2007.

What Does Walk-In Cooler Repair Cost?
Walk-in cooler and freezer repair at Boer Brothers is billed by the technician hour at published rates: $130 an hour to evaluate the problem during regular hours, with a two-hour minimum, then $175 an hour for the repair, with no minimum. There’s no trip charge, billing starts when the technician is dispatched, and a second unit on the same visit, like the freezer next to the cooler, adds no fee. The total depends on what failed: a door gasket or fan motor is a shorter job than a compressor or refrigerant leak.
| Service | Rate | Minimum |
| Issue evaluation, regular hours (Monday to Friday, 8 AM to 5 PM) | $130 per technician hour | 2 hours |
| Repair, regular hours | $175 per technician hour | None |
| After hours and weekends (Monday to Friday 5 PM to 9 PM, Saturday and Sunday 9 AM to 9 PM) | $215 per technician hour | 2 hours |
| Installing customer-provided equipment | $200 per technician hour | None listed |
That puts the evaluation minimum at $260 in regular hours and $430 after hours or on weekends. Rates are per technician, so a two-technician job bills both. We eliminated the $95 trip fee and the $87.50 additional-unit fee.

Walk-In Coolers and Freezers We Repair
We repair walk-in coolers, walk-in freezers, and combination boxes on just about any brand, whether the refrigeration is a packaged unit on top of or beside the box or a split system with the condensing unit on the roof or a pad outside. We work on both halves: the refrigeration system that removes heat, and the box that keeps it out, including panels, door, gaskets, closer, door-frame heaters, and drain lines. The data plate on the condensing unit lists the model and refrigerant, and a photo of it helps when you call.
Why Is My Walk-In Cooler Not Cooling?
A walk-in cooler that won’t hold temperature usually has one of four problems: warm air getting in through a door that doesn’t close or seal, an iced-over evaporator or stopped evaporator fans, a condensing unit that can’t shed heat because of a dirty coil or failed fan, or a refrigeration fault such as a leak or failing compressor. The first three are usually the cheaper fixes. Before you call, check that the door closes and seals on its own, that product isn’t blocking the evaporator fans, and that the outdoor unit is clear of leaves, dust, and grease.
| What you’re seeing | What it usually means | What it usually takes |
| Box is warm, compressor never shuts off | Dirty condenser coil, low refrigerant, or warm air leaking in at the door | Coil cleaning, leak search, or door work |
| Ice on the evaporator coil | Defrost heater or timer fault, blocked drain, failing fan, or door left open | Defrost diagnosis and drain clearing |
| Frost or ice around the door frame | Worn gasket, failed door-frame heater (freezers), or a door that isn’t closing | Gasket, heater, or door closer replacement |
| Water on the floor inside the box | Blocked or frozen drain line, or a failed drain-line heater (freezers) | Drain clearing or heater replacement |
| Condensing unit hums, but fan or compressor won’t start | Failed capacitor, contactor, or fan motor | Electrical diagnosis and part replacement |
| Short-cycling or tripping the breaker | Electrical fault, control fault, or a failing compressor | Diagnostic; often decides repair vs. replace |
| Display and thermometer disagree, or temperature swings | Failed sensor, thermostat, or controller | Control diagnosis and sensor replacement |
What Temperature Does a Walk-In Cooler Need to Hold in North Carolina?
41°F or colder. North Carolina’s food establishment rules adopt the FDA Food Code, which requires time/temperature control for safety (TCS) food to be held at 41°F or below. The state’s 45°F allowance for older equipment ended on January 1, 2019, so a walk-in holding 44°F today is out of compliance even if it passed inspection years ago. The Food Code also requires the thermometer to read the warmest part of the box, often near the door.
If your walk-in can’t hold 41°F at that thermometer, call for repair rather than waiting it out, and follow your food safety plan for the product. Keep the door shut and log readings and times; the technician will use them.
How Often Should a Walk-In Cooler or Freezer Be Serviced?
At least twice a year for the refrigeration system, more often near a kitchen exhaust. Heatcraft’s manual for its air-cooled condensing units schedules wiring and connection checks quarterly and condenser coil cleaning twice a year. Restaurant rooftop condensers collect grease and dust faster than that, and a fouled coil makes the compressor run longer. A service visit should cover the condensing unit, evaporator coil and drain, defrost, door gaskets and closer, and a thermometer check against a reference reading.
Between visits, staff can log temperatures at opening and closing, confirm the door closes and seals, keep product off the evaporator fans, and keep the outdoor unit clear. Boer Brothers offers commercial maintenance agreements for walk-ins and the rest of your kitchen equipment. They aren’t contracts and can be canceled with 30 days’ notice.
Should You Repair or Replace a Walk-In Cooler?
Repair the part that failed unless the box itself is failing. A walk-in is an insulated box (panels, floor, and door) plus a refrigeration system, and the two wear out on different schedules. A sound box with a failed compressor needs a refrigeration repair, not a new walk-in. Replacement is worth discussing when panels are wet or delaminating, the floor has heaved, ice forms inside the walls, or the refrigeration system needs a second major repair in a short span. Manufacturers generally don’t publish a service-life rating, so age alone shouldn’t decide it.
Refrigerant rules matter too. Under the EPA’s Technology Transitions rule, new remote condensing units installed from July 27, 2026 must use refrigerant with a global warming potential under 1,400, dropping to 150 or 300 in 2032. R-404A, common on older walk-ins, is rated 3,922. Existing equipment is exempt: the EPA states that a system may be serviced and repaired throughout its useful life, including replacing components. So repairing an R-404A walk-in is legal and often the right call, but replacing its whole refrigeration system means a newer refrigerant. That’s the point to price both options, and we’ll give you the comparison before you spend anything.

Walk-In Cooler and Freezer Repair Questions
When can I get a technician out?
Technicians are available 8 AM to 9 PM weekdays and 9 AM to 9 PM weekends. Evenings after 5 PM and weekends bill at the after-hours rate. Call 919-336-0271 for the soonest opening.
What do I do with my product while the walk-in is down?
Move TCS food to working cold storage as your food safety plan directs. If you’re short on space, we rent mobile cold storage: a cooler trailer delivered to your back door, set up and plugged in, so you can move product in right away. Same-day delivery is available to most areas, pending availability.
Do you charge a trip fee or a diagnostic fee?
No trip fee. Billing starts at dispatch at the evaluation rate above, and there’s no extra charge to check a second unit on the same visit.
Is ice buildup in a walk-in freezer normal?
Light frost that clears each defrost cycle is normal. Ice that keeps building on the evaporator coil, door frame, or ceiling panels is not; it usually means a defrost fault, a door that isn’t sealing, or a blocked drain. Don’t chip it off with a knife or screwdriver: puncturing a coil turns an ice problem into a refrigerant leak.
Can you repair a walk-in freezer door that won’t seal?
Yes. The cause is usually a torn or flattened gasket, a closer or hinge that no longer pulls the door shut, or on a freezer, a failed door-frame heater that lets ice hold the door open. Fix it early: a leaking door makes the whole system work harder.
My walk-in is reading 45°F. Can I keep using it?
Not for TCS food. North Carolina requires 41°F or below. Follow your food safety plan, move what you can to working cold storage, keep the door closed, and call for service.
Will you repair a walk-in you didn’t install?
Yes, regardless of who built or installed it, on just about any brand.
