Walk-In Freezer Repair & Installation
Freezers fail harder than coolers: the defrost system works constantly, the temperature differential is brutal, and frozen inventory is usually the most expensive product in the building.
The failures we see most
Defrost heater and termination-sensor failures that let the coil ice solid, defrost timer and board faults, condensing unit and compressor failures, low charge from a leak, evaporator fan motor burnout, and door-seal and heater-wire failures that let the frame ice up and the door stop closing.
Fast stabilisation, permanent repair
We get the box pulling down again as quickly as possible, help you protect product, and then fix the underlying cause — with a written explanation of what failed and why.
Prevent the next one
Scheduled service with full defrost verification, coil cleaning, gasket and heater-wire inspection, refrigerant checks and temperature logging is dramatically cheaper than one lost freezer load.
Frost is the symptom, not the fault
A freezer packed with frost has almost always got a defrost problem rather than a cooling problem. Every freezer ices its evaporator in normal use, and every freezer is supposed to melt that ice off on a timed cycle. When the defrost heater, the timer or the termination sensor fails, ice builds until it blocks airflow completely — and then the box warms up while the compressor runs constantly trying to fix it.
Chipping the ice off gets you a day. It comes back within the week, because the thing that removes it is still broken.
Door seals cost more than people think
The single most common thing we find on a struggling freezer is not a failed part. It is a door that no longer seals — a torn gasket, a dropped hinge, or a heater wire in the frame that has failed so the door frosts itself shut and gets forced.
Warm humid kitchen air leaking into a freezer condenses and freezes instantly. That is where the frost comes from, that is what the compressor is fighting, and it is why the energy bill went up before anything obviously broke. A gasket is a cheap part.
What it costs, and when we come out
Commercial diagnostic is $120, or $200 outside Monday to Saturday 8–5 and on Sundays. A freezer failure is worth calling out of hours for in a way a warm dining room is not — frozen product has a much shorter grace period once it starts to thaw, and it cannot be refrozen and sold.

Walk-In Freezer Repair — questions we get asked
What temperature should a walk-in freezer run?
0°F or below, typically between -10°F and 0°F. Product quality degrades quickly above that even before it thaws.
Why is the freezer door frozen shut?
The door frame heater wire or the gasket has failed, letting humid air condense and freeze at the seal. It is a straightforward repair, but leaving it damages the door and drives up the refrigeration load.
What temperature should a walk-in freezer hold?
0°F is the working standard for frozen storage. A few degrees above will not spoil product immediately but it shortens shelf life and starts the freeze-thaw cycle that ruins texture. If your freezer is sitting at 15°F it is not 'a bit warm' — something is wrong.
My freezer is full of ice but the product is still frozen. Is it urgent?
It is not an emergency tonight, but do not leave it. Ice buildup means the defrost cycle has failed, and it gets worse in one direction only. Left long enough it blocks the evaporator entirely and the box warms up with the compressor running flat out, which is how a $300 defrost repair becomes a compressor.
Can thawed product be refrozen?
That is a food safety judgement rather than an HVAC one, and it depends on how warm it got and for how long. This is exactly why we tell people to write down the temperature and the time when they first notice a problem. Your health inspector will ask.
