We hold temperature logs and food-safety pressure in mind on every call: pull-down times, superheat and subcooling numbers, defrost termination, and whether the box can safely hold product until the part arrives. When a repair needs a component we do not carry, we stabilize the load first and tell you plainly what the box will do overnight.
What we repair — and how we find it
Box not holding temperature
Low charge, restricted metering device, iced evaporator, failed defrost termination or a condenser choked with grease and lint.
Compressor short cycling
Pressure control setpoints, contactor and start components, overload trips, and head pressure caused by a dirty or undersized condenser.
Refrigerant leaks
Electronic and nitrogen leak location on suction lines, evaporator returns, brazed joints and Schrader ports, then evacuation and weighed-in recharge.
Iced or flooded evaporators
Defrost heaters, termination thermostats, timer or electronic defrost boards, drain-line heat and blocked condensate drains.
Controls and monitoring
Electronic controllers, sensors out of calibration, door switches, alarm setpoints and remote temperature monitoring that never trips.
Doors, gaskets and panels
Torn gaskets, sagging hinges, closers and sweeps that let humid Maryland air in and drive an evaporator into constant frost.
