Walk-In Coolers & Freezers — FAQ's

What causes a walk-in cooler to stop holding temperature?

Walk-in coolers lose temperature for a few common reasons — low refrigerant, dirty condenser coils, faulty evaporator fans, damaged door gaskets, or thermostat issues. Sometimes it’s simply a blocked airflow or ice buildup. A trained technician can diagnose the exact cause quickly and prevent the problem from leading to food-safety risks or inventory loss.

Excessive frost usually happens when warm air enters the freezer. That could be from worn gaskets, a faulty door heater, a failed defrost cycle, or a refrigerant imbalance. If you see heavy frost on the coils, ceiling, or product, schedule a service call right away — it can damage the system and reduce cooling performance.

With proper maintenance, most walk-ins last 15–20 years. Components like compressors, fans, controls, and gaskets may need replacement sooner, which is normal. Regular service helps extend lifespan and reduces expensive breakdowns over time.

Yes. Commercial walk-ins run continuously and require routine maintenance to stay efficient. Scheduled cleaning, gasket inspection, temperature checks, and coil maintenance help prevent breakdowns, reduce energy use, and keep temperatures food-safe. Preventative maintenance is one of the best ways to avoid emergency repairs.

If your system is older, constantly losing temperature, using extra power, or needing frequent repairs, a replacement may be more cost-effective. New systems run quieter, cooler, and more efficiently. A technician can assess whether repair or replacement is the right move.

Yes — we provide 24/7 emergency service for commercial walk-ins. Temperature issues can lead to product loss and business interruption, so we respond quickly to get your system stable and prevent further damage.
