A refrigeration failure is more time-sensitive than an HVAC failure. Every hour a walk-in drifts warm puts more of your inventory at risk.

We service commercial refrigeration for restaurants, grocers, convenience stores and food production across the Tri-Cities: walk-in coolers and freezers, reach-ins, prep tables, display cases and ice machines.

The faults are their own discipline — refrigerant charge in low-temperature applications, defrost timing and termination, evaporator fan and heater circuits, door gaskets and heaters, condenser fouling, and controls that have been changed over the years until nothing terminates properly.

Planned maintenance matters even more here than on comfort cooling. A condenser coated in kitchen grease may run fine until the first sustained hot spell and then fail when you need it most.

Response
Let the office know a walk-in is warming up, and we will move the call up the day’s schedule.
How it works

When a walk-in starts to warm up

  1. Call the office

    Let the office know it is a walk-in warming up, and we will move the call up the day’s schedule.

  2. We find the cause

    We check the charge, defrost timing and termination, fan and heater circuits, door gaskets and the condenser.

  3. We repair it

    We find and repair leaks, and set the controls so every cycle terminates properly.

  4. We help prevent the next one

    Condenser cleaning and planned maintenance help prevent most of the summer failures we see.

Refrigeration calls from food businesses get priority, because your stock is on the line.

Common questions

Before you book

How fast can you respond to a walk-in failure?

We prioritize refrigeration calls from food businesses, because your stock is at risk. Call (423) 357-1922 and tell the office it is a walk-in warming up, and we will move the call up the day’s schedule.

The freezer keeps icing up.

Usually a defrost problem — the timer, the termination sensor or the heater circuit — or warm moist air getting in past a failed door gasket. Both are routine to diagnose and neither gets better on its own.

Do you maintain refrigeration too?

Yes, and we recommend it. Kitchen environments foul condensers quickly, and scheduled cleaning prevents most of the summer failures we get called to.
