Walk-in cooler and freezer repair in Miami covers the condensing unit outside or on the roof, the evaporator and defrost system inside the box, the controls, and the door and gaskets. Our dispatch sends a technician any hour from the Medley head office or the SW 117th Ave service office, because a walk-in climbing past its safe range can cost a restaurant its product overnight.

The job
Why walk-ins fail, and why it's always urgent
A walk-in is a refrigeration system with a very large box attached. The condensing unit rejects heat outdoors or on the roof, the evaporator inside pulls heat out of the air, a defrost system keeps the evaporator from icing, and the box itself, its panels, door and gaskets, holds the cold in.
Any of those can let the temperature climb. Restaurants, markets and caterers can't wait for morning, so these calls are dispatched like a no-cool call at home.

What we see on this job
Walk-in not holding temperature
When a walk-in drifts warm, we check the easy causes first: a door left ajar or not closing, a gasket that no longer seals, an evaporator fan that stopped, or a condensing unit whose coil is packed with grease and dust. Then we check the refrigeration itself: pressures, the charge, the compressor and the controls. We tell the manager what can be fixed now and what needs a part, and we advise on moving product to another box while the repair is finished.
Evaporator icing in a walk-in
A block of ice on the evaporator coil means the defrost system isn't clearing it, airflow is blocked, or warm, moist air is getting into the box. Freezers are especially prone because every door opening brings in humid kitchen air that freezes on the coil. We check the defrost heaters, the defrost timer or control, the termination sensor and the drain line heater, which can freeze solid and leave meltwater with nowhere to go. We thaw the coil safely and fix what stopped defrost from working.
Door gasket and closer replacement
Worn door gaskets and closers are among the most common and least costly walk-in problems, and they account for a surprising share of warm boxes and icy freezers. A gasket that is torn, flattened or hardened lets warm air in all day. A closer or hinge that doesn't pull the door shut leaves it open a crack after every trip. We replace gaskets, adjust or replace closers and hinges, and check the door heater on freezers so the door doesn't freeze to its frame.
Local conditions
Walk-ins and storm season in Miami-Dade
After Hurricane Irma, about 92 percent of FPL customers in Miami-Dade lost power, and some went more than a week without it, which is the kind of outage that empties walk-ins across the county. Grade-level condensing units in coastal areas also face flooding, and salt left on their coils after a storm speeds corrosion, so post-storm restarts get an electrical and coil check before the box is reloaded.
