Your walk-in cooler or freezer is one of the most important assets in your business. Whether you’re storing food, beverages, flowers, or biological materials, keeping your unit in peak condition ensures product quality, energy efficiency, and long-term reliability. The best way to prevent costly downtime is through seasonal maintenance—small, routine checks that help you catch problems early.
While some tasks are straightforward and DIY-friendly, others require professional tools and expertise. That’s where Arctic Walk-Ins comes in. Our team can handle the complex repairs and calibrations so your system always runs at its best.

Walk-In Freezer Maintenance: 5 Common Mistakes to Avoid
Spring: Deep Cleaning & Reset
Spring is the season for fresh starts, and your cooler or freezer should be no exception. After months of winter wear, focus on cleaning and recalibrating.
- Clean condenser and evaporator coils to restore efficiency.
- Check door seals for cracks or warping from cold, dry air.
- Calibrate thermostats and alarms to make sure they read accurately.
- Look for corrosion or moisture buildup on walls, floors, and hardware.
- Evaluate startup performance if your unit was shut down over winter.
Summer: Peak Performance Check
Hot weather puts extra strain on refrigeration systems. A summer check-up helps prevent breakdowns when you need your cooler or freezer most.
- Monitor temperature fluctuations that signal stress from heat.
- Inspect fan motors and air circulation to avoid hot spots.
- Watch for excessive frost buildup in freezers.
- Clean drainage lines to prevent backups and leaks.
- Replace filters and check refrigerant levels to keep the system running smoothly.
If you notice your unit struggling in the heat, it may be time to inspect or replace key parts. Browse high-quality replacements at MyWalkInParts.com.
Fall: Prep for Cold Weather
As temperatures drop, take steps to prevent freeze damage and ensure reliable winter operation.
- Test defrost systems in freezers before the weather turns.
- Reinspect door gaskets to keep cold air in and warm air out.
- Inspect insulation and weather stripping for signs of wear.
- Confirm lighting and electrical safety inside and outside the unit.
- Schedule professional service to handle any lingering issues before winter stress hits.
Winter: Freeze Protection
Cold air outside your unit doesn’t always mean efficiency inside. Winter presents unique risks like ice buildup and heat loss through doors.
- Ensure doors fully seal to avoid heat leaks and ice formation.
- Check for ice accumulation on floors or thresholds that create hazards.
- Monitor efficiency when ambient temps are low—systems can overwork.
- Inspect heated door frames (if installed) to confirm they’re functioning.
- Perform emergency part replacements when necessary to avoid downtime.
