Commercial refrigeration & walk-in repair in the DMV
When a walk-in starts climbing, you're on a clock measured in inventory dollars. NEXUS BUILD repairs commercial refrigeration across DC, Maryland, and Virginia — walk-in coolers and freezers, reach-ins, prep tables, and line refrigeration — with 24/7 emergency dispatch because product doesn't spoil on a schedule.
We also install and replace walk-ins as part of our kitchen construction work, so our techs think beyond the compressor: door gaskets, panel insulation, drain lines, and airflow all get checked, because any of them can be the real reason your box can't hold temperature.

When the walk-in is warm at 10 p.m.
Call (202) 827-6511. We triage over the phone — sometimes a quick check keeps product safe until a tech arrives — then dispatch. If a repair can't happen immediately, we'll help you plan cold-chain triage so inspection day doesn't turn into a disposal day.
Frequently asked questions
How fast can you get to a failed walk-in?
Emergency refrigeration calls get priority 24/7 dispatch across the DMV. Call rather than email — the phone triage alone can save your inventory.
Repair or replace an old walk-in?
We quote both honestly. A failing compressor on a 20-year-old box with wet insulation is money down the drain; a gasket and a recharge on a solid box is a cheap fix. You'll get the real answer either way.
Do you do preventive maintenance on refrigeration?
Yes — coil cleaning, gasket checks, refrigerant verification, and drain clearing on a schedule. Most catastrophic failures telegraph themselves weeks ahead to anyone who looks.
Refrigeration acting up?
If it's failing right now, call (202) 827-6511. Otherwise, describe the unit and symptom and we'll schedule a diagnosis.
