Quick answer
Walk-in cooler and walk-in freezer repair across the Twin Cities covers sealed-system work (leaks, low charge, compressor and TXV), defrost circuits (heaters, terminators, defrost boards and timers), evap and condenser fan motors, door hardware and gaskets, drain-line freeze-ups, and remote rooftop or pad-mount condensing units. Every technician holds EPA Section 608 Universal certification and does recovery, brazing, deep evacuation, and factory-spec recharge in-house on Copeland Scroll condensing units, Heatcraft evaporators, and Bohn / Larkin sealed platforms. Commercial diagnostic is $199, credited toward the repair on approval. Most walk-in repairs land $385–$1,800 all-in; sealed-system and compressor work is always quoted in writing first. Same-day priority for food service when the call lands before 2pm, plus after-hours emergency dispatch. 1-year written parts-and-labor warranty on every job.

Repair vs. replace
Most walk-in coolers run 15–20 years if condenser fans, gaskets, and drain lines stay healthy. A single preventive condenser-fan replacement is roughly 3% of replacement cost — and avoids refrigerant recovery, disposal, and 4-week equipment lead times.
A restaurant walk-in stocked with $2,400 of protein and dairy crosses the HACCP 41°F / 4-hour line well before a same-day tech can arrive. A quarterly PM contract typically pays back on the first prevented spoilage event.
Lost service-window revenue at a Twin Cities restaurant routinely runs $2,400–$6,000 per closed dinner shift. A $585 same-day defrost-heater swap is a very different decision than a $14,000 walk-in replacement on a 4-week lead time.
A felted condenser coil can lift compressor head pressure 20–40°F, raising kWh draw 15–25% on the same cooling load. Quarterly cleaning is built into PM pricing and typically pays back on the next two electric bills.
EPA Section 608 Universal certified — recovery, brazing, deep evacuation, and factory-spec recharge are done by our own techs on Copeland Scroll, Heatcraft, and Bohn / Larkin platforms. We do not sub out refrigeration.
Liability and workers-comp certificates issued at no charge to the named insured / additional-insured on request. After the first paid visit, established accounts get Net-15 or Net-30 invoicing and PO acceptance.

If your equipment is down right now
Shift dairy, raw protein, and TCS prepped foods into a working reach-in or a neighboring walk-in. Log the time you started — your insurer and HACCP plan will both ask.
Photograph the controller and an internal thermometer. If product crosses 41°F for more than 4 hours, follow your HACCP plan and document anything discarded for insurance.
Remove the front grille and vacuum or brush the condenser coil on the condensing unit. A felted coil is the root cause about 40% of the time and often gets the unit running while you wait.
Look for a torn or compressed gasket, a propped-open door, or a stalled evaporator fan. Any of these will ice a coil overnight — clear ice off the coil and confirm fans spin freely before dispatch.
Sealed-system work requires Section 608 certification. Call (651) 364-7466 — commercial calls placed before 2pm typically get a same-day window with average on-site arrival under 4 hours across Minneapolis and Saint Paul.
Walk-in troubleshooting
Six failure patterns account for most walk-in cooler and walk-in freezer calls we run in the Twin Cities. Match the symptom on your box to the row below before you call — it shortens the diagnostic and tells us which parts to load on the truck.
Usual cause: Felted condenser coil, failed condenser fan motor, or low refrigerant charge from a slow leak
What we do: Coil cleaned, condenser fan amp-draw tested, superheat and subcooling read at the condensing unit, leak search with electronic detector before any charge is added
Typical all-in: $385–$885
Usual cause: Defrost heater burnout, failed termination sensor, stuck defrost board or timer, or a door gasket pulling humid air in
What we do: Coil cleared, heater resistance and termination sensor tested, defrost schedule reset to the box load, gasket and door sweep replaced when infiltration is the driver
Typical all-in: $385–$685
Usual cause: Drain-line freeze-up, failed drain-line heater wire, or a plugged P-trap outside the box
What we do: Drain line thawed and flushed, heater wire continuity tested and replaced, trap cleared and pitch verified so the line drains between defrost cycles
Typical all-in: $285–$585
Usual cause: Weak start relay or run capacitor, pitted contactor, high head pressure, or a low-pressure control cycling on charge loss
What we do: Start components tested under load, contactor replaced, head pressure and cut-in / cut-out setpoints verified, hard-start kit fitted on Copeland Scroll units where warranted
Typical all-in: $485–$1,485
Usual cause: Sagging cam-lift hinges, compressed magnetic gasket, failed threshold heater wire on a freezer door
What we do: Hinges shimmed or replaced, full gasket kit fitted, latch and strike realigned, threshold heater replaced on Kason and Component Hardware systems
Typical all-in: $285–$585
Usual cause: Failed temperature probe, defrost board fault, or setpoint drift on Danfoss, Ranco, Dixell, or Heatcraft Beacon II controls
What we do: Probe resistance checked against a reference, board or control replaced, setpoint, differential, and defrost intervals recalibrated to the product load
Typical all-in: $285–$685

FAQs
Restaurant walk-ins are dispatched as food-service priority — most Minneapolis and Saint Paul addresses get a same-day window when the call lands before 2pm, with average on-site arrival under 4 hours. After-hours emergency service is available when product is on a clock.
Yes — EPA Section 608 Universal certified. We do our own recovery, brazing, deep evacuation, and factory-spec recharge on Copeland Scroll condensing units, Heatcraft evaporators, and Bohn / Larkin sealed platforms. We do not sub out refrigeration.
Heatcraft (Larkin / Bohn / Climate Control), Copeland, Tecumseh, Bally, Russell, Master-Bilt, Norlake, Kolpak, Amerikooler, and Arctic — both self-contained top-mount units and remote rooftop / pad-mount condensing units, indoor and outdoor.
$199 commercial diagnostic, credited toward the repair when approved. Most Twin Cities walk-in repairs land $385–$1,800 all-in — a fan motor, contactor, or defrost heater lands at the low end; compressor or evaporator-coil replacement runs higher. Written 1-year parts-and-labor warranty on every job.
Yes — the platforms overlap. Freezers add defrost heaters, defrost termination sensors, drain-line heaters, and threshold heater wire, all of which we service. Low-temp sealed systems (R-404A, R-448A) are handled the same way as medium-temp cooler systems.
Yes. Remote Copeland Scroll rooftop and pad-mount condensing units are a standard part of our walk-in work — line-set brazing, receiver work, condenser-fan and head-pressure controls, and reconnect to indoor evaporators on the same visit.
Yes — quarterly PM contracts for restaurants, bars, breweries, and grocery covering condenser cleaning, refrigerant-charge verification, door-gasket inspection, drain-line clearing, and priority dispatch when something does fail. COI available same-day.
Fully insured with $2M general liability, EPA 608 Universal certified for all sealed-system refrigerant work, and background-checked technicians. COIs available same-day for property managers, landlords, and building GCs.
Yes. We issue COIs naming your property manager, hospitality group, hospital facilities office, or municipal account as additional-insured at no charge — typically the same business day. General liability and workers' comp are in force year-round; we can raise limits per contract on request.
First visit is card-on-file or COD. Once an account is established, we invoice Net-15 or Net-30 with itemized statements aligned to your accounting cycle. We accept POs from restaurant groups, hotel brands, property management firms, school districts, and city and county accounts. ACH and card payments both fine.
Yes — quarterly, semi-annual, and annual PM plans tiered by equipment count and equipment class. Every visit includes condenser cleaning, drain flushing, gasket and hinge inspection, electrical-tightness verification, controller and setpoint check, and a written report you can hand to insurers, health inspectors, or franchisors.
Every technician holds EPA Section 608 Universal certification covering R-404A, R-448A / R-449A (Solstice N40, Opteon XP40), R-290 hydrocarbon systems where code permits, and legacy R-22. Cooking-equipment techs are gas-certified for natural gas and LP on ranges, fryers, ovens, and combi-ovens.
Yes. We coordinate dock and freight-elevator windows in advance, badge in through hotel or hospital engineering, and work around banquet, service-window, and clinical-department timing. Overnight and pre-open service is available when a daytime window won't work.
Yes — after-hours, weekend, and holiday emergency dispatch is available for refrigeration, ice, and warewashing failures across the Twin Cities metro. A published after-hours premium applies and is confirmed in writing before the tech leaves the shop.
A 1-year written parts-and-labor warranty on every commercial repair — the same failure mode, on the same unit, within 12 months is covered at no additional charge. Some sealed-system components carry an extended manufacturer warranty on top; those terms are itemized on the invoice.
Yes. Truck-mounted reach-ins, undercounter units, generator-fed ice machines, and mobile prep tables are all serviceable — we typically shop-visit at your commissary or overnight parking rather than roadside so the unit can stabilize before diagnosis.
Yes. Written estimates are issued before any sealed-system, compressor, or major-component work. On request we provide inspector-ready documentation: repair scope, part numbers, refrigerant type and charge, and the date service restored the unit to spec.
