Walk-in Freezer Rooms Built & Repaired in Sydney
Walk-in freezer rooms designed, built, repaired and serviced to spec — sub-zero storage and blast freezing for kitchens, processors and cold storage. Thicker panels, heated door frames and a proper defrost cycle, sized for the load not guesswork. Whether you're fitting out a new room or your freezer just stopped holding temperature, we sort it across Greater Sydney.

Building a new freezer room — or rescuing one that's failing?
Most freezer room enquiries fall into one of these two. Tell us which you're chasing and we'll point the right tech and the right quote at it. Need a fast fix? Start with our commercial freezer room repairs in Sydney.
New install & fit-out
A new walk-in freezer from a clean sheet — or replacing a tired one. We size the refrigeration for the much bigger sub-zero load, supply and build the panel room with heated doors, and commission it to a stable frozen temperature.
- Site measure, heat-load calc & layout
- 100–150mm insulated sandwich-panel build
- Condensing unit + evaporator for sub-zero load
- Heated door frames, gaskets & strip curtains
- Electric/hot-gas defrost + written temp record
Repair, regas & service
Freezer creeping warm, iced over, leaking water or tripping out? A licensed tech finds the real fault — not just a re-gas — and gets you back in spec before stock thaws. After-hours failures go straight to our 24/7 breakdown line.
- Not holding temp / drifting above −18°C
- Heavy ice-up — failed defrost cycle
- Iced or jammed door, perished heated gasket
- Failed fan motor, contactor or controller
- Refrigerant leak found & repaired before any regas
The walk-in freezer, spec'd properly
A walk-in freezer asks more of every component than a chiller does. Here's what we specify and service for sub-zero rooms.
100–150mm PIR/PUR-cored panels — the thicker core a freezer needs so the unit isn't running flat-out forever.
A bigger, correctly sized condensing unit and low-temp evaporator to handle the deep sub-zero pull-down and hold.
Sub-zero doors need a heated frame so they don't ice shut, plus self-closers and gaskets that seal against frost build-up.
A proper timed defrost cycle clears coil ice so the freezer keeps performing — off-cycle defrost won't cut it below zero.
Digital controllers, high-temp alarms and data-logging so a drift gets flagged before stock is lost.

How cold is a freezer room? Walk-in freezers run frozen — typically around −18°C as common industry practice (not a fixed regulation). Like cool and cold rooms, the goal is to keep food well clear of the 5–60°C danger zone the NSW Food Authority and FSANZ warn about.
Indicative freezer room price ranges
A freezer room costs more than a chiller of the same size — bigger refrigeration, thicker panel and heated doors all add up. These are typical Sydney supply-and-install ranges for a standard walk-in freezer — we confirm your exact price after a site measure.
| Freezer room size | Typical use | Panel core | Indicative range* |
|---|---|---|---|
| Small modular (kitchen / venue) | Frozen stock, ice-cream | 100mm | A$10,000 – A$16,000 |
| Modular (retail / processor) | Bulk frozen storage | 100–150mm | A$16,000 – A$28,000 |
| Large / engineered cold storage | Warehouse-scale frozen hold | 150mm | A$30,000 – A$200,000+ |

What drives the price
Size & volume
More cubic metres = bigger refrigeration and more panel. The single biggest lever.
Target temperature
A deep freezer needs a far bigger unit, thicker panel and longer pull-down than a chiller.
Heated doors & defrost
Heated frames and an electric or hot-gas defrost cycle are essential below zero — and add to the build.
Plant location & pipe run
Remote condensers on a roof with long pipe and crane access cost more than a packaged unit.
Doors & access
Sliding doors, multiple doors, ramps and strip curtains all add to the build.
Controls & monitoring
High-temp alarms, data-logging and BMS integration for compliance-critical sites.
Freezer room, cold room or cool room?
A freezer room goes sub-zero — typically around −18°C to −25°C — to freeze and hold stock long-term, and it needs heated doors and a proper electric or hot-gas defrost cycle to keep working. A cold room sits at 0°C to +5°C for chilled storage, and a cool room a touch warmer at +2°C to +8°C for fresh produce and drinks. Get the type wrong and you'll either spoil stock or pay to over-refrigerate it.
