Frozen stock does not wait for a convenient time to start thawing. A freezer running just a few degrees warm can go unnoticed for hours, and by the time anyone checks, a full day’s stock can already be compromised.
Zeal Group handles commercial freezer repair Melbourne-wide, with ARCtick-licensed technicians who get units back to around -18°C before more stock is lost. Regular freezer maintenance is also available to help prevent faults and reduce unexpected breakdowns.

Zeal is a good commercial refrigeration company with a professional team! The temperature of my cool room was very high last week, and I called Zeal to find someone to help me. The responding time is super fast from them and a very awsome tech came to my cool room and fixed the problem quickly. From the start I called the service until they finished the problem, the whole process was super fast and professional, and all the people from Zeal were very kind. And the price is very GOOD!!! If my equipment is broken in the future, I will call Zeal without any hesitation.

My Coolroom broke down with all my fresh Mushrooms going bad at 1am in the morning on a Saturday / Sunday and Zeal Refrigeration saved my life and my business for the late night call out. He adjusted all the settings along with re wiring and replacing a fan so now my Coolroom is running perfectly! Thanks again 👍 - Jaz

Urgent call out 3pm as our main fridge broke. Not only was admin amazing in organising the tech, they arrived after hours around 6:00pm and carried out the repair DURING service.
We’ve been in F&B for close to 10 years but no company has come close to the professionalism of Zeal.
They will have all our work moving forward.

Common Issues That Require Commercial Freezer Repair Service
If stock takes longer than usual to freeze after a delivery, the freezer probably isn’t keeping its temperature right, often because shelves are overpacked and blocking airflow, or a fan is failing and leaving warm patches. It’s worth sorting early, since a freezer that keeps struggling to hold its setpointwill only get worse.
Heavy Frost or Icing
Thick frost usually comes from a faulty defrost heater, timer, or door seal, which lets ice build up on the coil and drags down cooling. Get any frost caused by defrost failure checked before it puts your stock at risk.
Water Leaks or Pooling
Water pooling under the freezer is usually a blocked or iced-up drain, or a drain heater that’s died. Sometimes it’s just a damaged or badly positioned drain tray. Either way, sorting it fast stops a slip hazard in a busy kitchen.
Noisy or Hot-Running System
A freezer that’s getting louder, running non-stop, or pushing up your power bill is working too hard, often due to dirty condenser coils or not enough airflow around the unit. Keeping it clean and giving it space helps cut compressor stress linked to noise and high power bills.
Refrigerant Leaks
Weakened cooling, slow temperature recovery, or oily marks around the pipes point to a refrigerant leak, with frost on just part of the coil as another warning sign. A licensed tech needs to find and fix the leak before recharging, since refrigerant loss can lead to full freezer failure.
Control or Probe Faults
Faulty sensors or controllers can give wrong readings, false alarms, or random shutdowns, and sometimes show a safe temp even while the freezer’s warming up. Get unexplained temperature issues or repeat alarms checked early, since catching afreezer probe error sooner keeps readings accurate.
Freezer Types We Repair
Common commercial freezer setups we work on include:
Upright & Underbench Freezers
Reach-in units near the cookline or under a bench, opened constantly during service.
Chest Freezers
Top-opening units that hold cold air well, used for bulk or long-term storage in cafés and bottle shops.
Walk-In Freezers
Large-capacity cold rooms used by food manufacturers, central kitchens, and distribution centres.
Display Freezers
Glass-door units in supermarkets that keep stock visible while holding temperature in front of customers.
Blast Freezers
Units that rapidly chill food to freezing temperature, used in food production and central kitchens.
Freezer Brands We Repair
Brands covered include Williams, Turbo Air and Hoshizaki underbench and upright units, Bromic chest and ice cream display freezers, Skope ActiveCore freezers, Hussmann and Thermaster. Freezers differ in how they defrost, drain, and control temperature, so we identify the model from the data plate and check parts before the repair starts. Parts for most models are carried on the van, with lead times confirmed on site if something is missing.
Our Commercial Freezer Repair Process
Initial Assessment
Tell us the temperature, any alarms, and how much stock is at risk, so urgent jobs are booked first.
Fault Diagnosis
A commercial freezer technician checks the defrost system, drains, seals, and electrical supply to find the fault, then quotes the cost before any repair begins.
Repair
Common faults, such as worn seals, faulty heaters, or temperature probes, can often be fixed in one visit using parts carried in the service van. Refrigerant leaks, however, take longer to resolve, as a licensed technician must locate and repair the leak before recharging the system.
Testing & Handover
Temperatures and the defrost cycle are checked until the unit settles, with notes left on what was wrong and what was fixed.
Commercial Freezer Maintenance in Melbourne
If a freezer starts icing up faster, running longer than it used to, or the door seal feels a bit soft, that’s usually the early stage of a fault, not yet a breakdown.
Freezers are opened far less often than fridges, so they don’t need servicing as frequently, but when something does go wrong, especially the defrost system, the consequences tend to be more serious. Here’s what a service visit covers:
Clean condenser and evaporator coils to keep heat transfer and cooling stable
Check refrigerant levels and defrost cycle to prevent temperature drift
Clear and flush drains to stop pooling water and refreezing
Calibrate controllers and probes, and check airflow around the unit
Inspect door seals, hinges, and heaters to stop warm air getting in
Restaurants, cafés, pubs and clubs, where under-bench and upright freezers sit close to the cookline and are opened constantly through service.
Supermarkets and bottle shops, where display and storage freezers have to hold temperature in front of customers.
Food manufacturers, central kitchens and distribution centres, where walk-in and blast freezers run under heavy load.
Cold storage environments, where frozen food has to stay frozen without a break.
Frequently Asked Questions
Do you repair commercial freezers after hours and on weekends?
Yes. Urgent faults are attended at night, on weekends, and on public holidays, with a target of on-site within 2 hours. For a confirmed time, call 1300 104 210 or see emergency repairs.
What should I do if my commercial freezer stops working?
Keep the door shut, call for a repair straight away, and move stock to another freezer if possible. Australian food safety advice suggests a full freezer holds food frozen for up to 48 hours with the door closed, and a half-full one for about 24.
Why is my commercial freezer not freezing?
If the compressor is running but the freezer stays warm, the cause is usually one of the faults covered above. If the compressor will not start at all, that is an electrical fault rather than a cooling problem.
Is it cheaper to repair or replace a commercial freezer?
Repair is usually the cheaper option for most faults, including seals, heaters, and sensors. Replacement tends to make more sense for older units with a major fault like compressor failure, and a technician can advise after diagnosis.
How much does commercial freezer repair cost?
Cost depends on the fault, the parts, and the unit size. Door seals, heaters, and sensors are usually the smaller jobs, while a compressor replacement is typically the biggest, and the repair is quoted after diagnosis.
