Pierre Refrigeration Services repairs commercial reach-in heating systems for kitchens and stores across Snellville and Gwinnett County. A reach-in that runs constantly but sits warm is usually short of airflow rather than short of refrigerant — a condenser coil packed with grease and dust, or a failed evaporator fan. Pull the grille and look at the coil first.

What fails, and what it looks like

Your reach-ins live in the hottest, greasiest air in the building and breathe through a grille down at floor level. Most of what goes wrong follows from that.

Component What you see
Condenser coil Unit runs continuously, the compartment sits five to ten degrees warm, and the grille is furred with grey grease.
Evaporator fan motor Compressor is running and the coil is cold, but no air moves inside the cabinet and only the top shelf cools.
Door gasket Sweating or ice around the door frame, a visible gap at a corner, and a gasket that no longer holds a slip of paper.
Defrost control Cooling falls off a little more each day until the evaporator behind the rear panel is solid ice.
Condensate drain and pan Water in the bottom of the cabinet or on the floor in front of it, worst on humid days.
Start components A click and a hum every few minutes with no start, or a breaker that trips when the unit tries to run.

Symptoms on reach-ins & under-counters, and how long you have

Reach-ins usually give you a few days of warning. What yours is doing tells you whether it is a visit you can schedule or one you want today.

How a technician finds the fault

A reach-in is a small sealed system in a hostile spot, so we start with the two things your kitchen controls — air and doors — before anything gets connected to gauges.

  1. Measure the cabinet at product level

    Not at the vent and not on the built-in display. A thermometer in a cup of liquid on the middle shelf gives the number that matters for food safety.

  2. Pull the grille and look at the condenser

    In a kitchen this coil loads with grease as well as dust, and a blanketed coil is the single most common reason a reach-in runs all day and stays warm.

  3. Confirm the evaporator fan is turning

    A cold coil with no air over it cools nothing but itself. If the fan is dead the cabinet stratifies, which is why the top shelf freezes while the bottom spoils.

  4. Check the door seal end to end

    A slip of paper closed in the door should drag coming out. Where it pulls free, warm humid air is being pumped in every minute the unit runs.

  5. Look behind the rear panel

    The evaporator hides there. Ice across it means defrost has stopped working; a clear coil with a warm cabinet moves the diagnosis to charge or compressor.

  6. Test the electrical side under load

    Start components, relays and overloads are checked while the unit attempts to start. A hum without a start is usually there, not in the compressor itself.

What moves the cost of the repair

Reach-ins are the least expensive commercial refrigeration to fix and the easiest to let go too far. What decides which one you are looking at:

Pushes it up

  • A sealed-system repair, where recovery, brazing and evacuation start to approach what the cabinet is worth to you
  • A discontinued model where the fan motor or control has to be adapted rather than replaced
  • A unit built into cabinetry or under a counter run, which has to come out before anyone can reach the back of it
  • Several of your units failing together, which almost always means the kitchen ventilation is the real problem

Keeps it down

  • Condenser cleaning before the compressor has spent months running against high head pressure
  • Gaskets, fan motors, defrost controls and drain work, which are accessible parts and common stock
  • Catching a stratifying cabinet early, while it is still a fan motor and not a shelf of spoiled product
  • Having the model and serial off the data plate ready when you call

You get the diagnosis and the number before any work starts — and a plain answer when the unit genuinely is not worth saving, rather than a replacement quote you have to go and get a second opinion on.

Questions operators actually ask

Why is my reach-in cooler running constantly but not cold?
Nine times out of ten the condenser coil behind the grille is packed with grease and dust. The unit runs without rejecting heat, so it never satisfies. Cleaning that coil is routine maintenance, not a repair.
How often should a commercial reach-in condenser be cleaned?
At least twice a year, and quarterly in a kitchen with fryers or a griddle. Grease-laden air loads a coil far faster than dust alone, and a blanketed coil is what kills compressors in commercial reach-ins.
Why is the top shelf freezing and the bottom shelf warm?
That is stratification, and it means the evaporator fan has stopped moving air. The coil keeps making cold that never gets distributed, so it piles up at the vent while the rest of the cabinet drifts.
Why is there water in the bottom of my reach-in?
The condensate drain is blocked or the pan has shifted. Every cooler makes water as it defrosts, and it has to reach a pan or a drain — when it cannot, it runs into the cabinet instead.
Is a reach-in worth repairing or should I replace it?
Anything on the accessible side — fans, gaskets, controls, drains, condensers — is worth repairing on almost any unit. The honest replacement conversation starts when a sealed-system repair meets a cabinet that is already rusted or out of production.
My reach-in clicks and hums but will not start. What is that?
That is the compressor trying to start and failing, usually on a relay or a start capacitor rather than the compressor itself. Leave it off rather than resetting it repeatedly — each failed start heats a winding that has no way to cool.
