Refrigeration is the single biggest line item in a supermarket's operating budget — typically 40–60% of total electricity use, and the most expensive single thing that can fail during trading hours. Hart Air designs, installs and services refrigeration for full-line supermarkets, IGAs, convenience stores and independent grocers across Brisbane and Moreton Bay.
From swapping a multi-deck dairy case overnight to project-managing a full CO2 transcritical refit, we know how to keep a supermarket cold without taking the shop offline.

What we work on across Brisbane supermarkets
Most of a Brisbane supermarket's refrigeration footprint falls into a familiar set of categories. We service all of them:
- Multi-deck open cases
Dairy, deli, prepared meals, smallgoods — typically 1.5m–3.75m runs with night blinds and air curtains.
- Glass-door upright freezers
Ice cream and frozen meals — 2-door, 3-door and 5-door cabinets, R290 or remote-rack.
- Service-over counters
Butcher, deli and seafood counters with refrigerated wells and rear coolroom support.
- Walk-in coolrooms & freezer rooms
Back-of-house cold-chain, link-loaded directly behind the multi-deck runs.
- Central plant & condensing racks
R448A/R449A racks, CO2 transcritical, hybrid CO2 cascade for full-line supermarkets.
- HVAC integration
Anti-sweat controls, store dehumidification and case heat-recovery into the warehouse HVAC.
The 5 problems we see most in Brisbane stores
- Air curtain failure on multi-deck cases. A blocked return-air grille or a leaning shopper destroys the cold curtain — cabinet temperature drifts up by 2–4°C within minutes. We re-balance airflow and re-stock to the load line.
- Iced-up evaporators in glass-door freezers. Usually failed defrost timers or blocked drains. Fast fix once isolated.
- Refrigerant leaks on long pipe runs. Long suction lines from rack to case have many joints. We pressure-test, locate, repair, recover and recharge.
- Condenser fouling on roof-mounted plant. Brisbane dust, pollen and ageing fan motors. Quarterly cleaning prevents most call-outs.
- Controller drift. Sensors out of calibration give false confidence. We re-calibrate as part of every service and replace probes annually.
Refrigerant choice in 2026
Refrigerant strategy is the single biggest decision in a supermarket refit. The Australian HFC Phase-Down is steadily reducing the supply of high-GWP gases — R404A in particular is becoming expensive and harder to source. Our default recommendations for Brisbane supermarkets:
- CO2 (R744) transcritical or cascade for full-line supermarkets >1,000m². Higher capex, dramatically lower lifetime refrigerant exposure and GWP.
- R448A or R449A for retrofitting existing R404A central racks. ~65% lower GWP than R404A and a clean drop-in for most rack designs.
- R290 (propane) self-contained cases for IGAs, convenience stores and grocers — limited by charge per circuit but very efficient.
R404A is service-and-survive only for existing equipment. We won't specify it on a new build.
Compliance: FSANZ, AS/NZS 5149, ARCtick
- FSANZ Standard 3.2.2 — chillers ≤5°C and freezers ≤-15°C target with documented monitoring. We supply calibrated probes and 4G data loggers integrated into your store BMS.
- AS/NZS 5149 — refrigeration system safety, machinery-space ventilation, charge limits, pressure relief.
- ARCtick licensing — refrigerant handling logs, recovery and decant records kept on file.
- Queensland Development Code MP4.4 — outdoor condensing rack noise limits at boundary, important for any supermarket near residential.
- Brisbane City Council and Moreton Bay City Council Environmental Health Officers regularly audit supermarket temperature records — our commissioning and ongoing service packages produce audit-ready documentation by default.
Energy & running cost
A mid-size Brisbane IGA can burn 350,000–650,000 kWh/year on refrigeration alone. At current QLD small-business tariffs of 28–34¢/kWh, that's $100,000–$220,000/year. Practical upgrades that consistently pay back fast:
- Doors on multi-deck dairy cases
Retrofit glass doors cut cabinet energy use by 30–45% and lift product temperature by less than 0.5°C.
- EC fan motors throughout
60–70% lower fan power across hundreds of fans = serious savings.
- LED case lighting
Less radiant heat into the cabinet, less refrigeration work, brighter merchandising.
- Heat recovery into store HVAC
Reclaim condenser heat for hot water and winter heating.
- Floating head pressure & EEVs
10–18% off compressor run-time, especially on cool Brisbane nights.
- QLD energy-efficiency rebates
Several state-level programs subsidise lighting and refrigeration upgrades for SMEs — we'll check current eligibility.

Trading without downtime
A supermarket can't go offline for a week. Hart Air stages refits in zones — typically one cabinet bay or one aisle at a time — with portable cold storage trailers parked at the back dock to hold stock during the change-over. Major plant works run overnight between trading hours. Most of our Brisbane supermarket refits hit zero closed-store days.
If a cabinet fails during trading, our emergency team is on call 24/7 — see emergency refrigeration repairs or our wider refrigeration repairs page.
