Freezer work is unforgiving: a defrost circuit that quits will bury an evaporator in ice within a day, and a slow leak shows up as long run times before it ever shows up as a temperature alarm. We read run time and superheat, not just the thermometer on the door.
What we repair — and how we find it
Freezer not holding 0°F
Charge, metering device, condenser rejection and evaporator airflow measured through a full cycle.
Defrost failures
Defrost heaters, termination thermostats, timers and electronic defrost boards, plus drain-line heat.
Ice buildup on coil or ceiling
Door infiltration, gasket and sweep failures, strip curtains and vapor-barrier problems.
Compressor lockouts
High and low pressure controls, overloads, contactors, start components and crankcase heaters.
Refrigerant leaks
Leak location, brazed repair, evacuation and weighed-in recharge with a written report of the leak site.
Drains and floor ice
Frozen condensate drains, heated drain lines, traps and pans.

Commercial Freezer Repair — questions we get asked
- Do you repair walk-in freezers?
- Yes. Walk-in freezers, reach-in and chest freezers, and the condensing units serving them — this page covers both walk-in and reach-in freezer work.
- My freezer coil is packed in ice. What now?
- That is almost always a defrost failure or heavy door infiltration. Switch refrigeration off so the coil can thaw, keep the door shut, and call 443-295-4865 — thawing while we drive out often saves an hour.
- How quickly can you respond?
- We offer emergency and priority commercial response in the Maryland / DC metro. Same-day is common from our Columbia base; we tell you honestly when the answer is next business day.
- Do you replace failed condensing units?
- Yes, when the numbers make repair uneconomical. We show you the readings behind that recommendation before quoting replacement.
- What does commercial freezer service cost?
- Commercial diagnostics are quoted by equipment and location before dispatch — call for pricing. Residential service calls are priced at checkout.
