Queensland summers aren’t gentle—and neither is the toll they take on your commercial refrigeration systems. With temps climbing past 30°C and humidity averaging 70%+, now’s the time to prep your equipment before the heatwave hits. One failure can mean $5,000+ in spoiled stock, lost revenue, and unhappy customers. Don’t sweat it—these 7 practical tips will help you stay cool, compliant, and cost-effective all summer long.

1. Clean the Condenser Coils: Beat the Heat at the Source

Condenser coils work overtime in summer, releasing heat pulled from inside your unit. But in QLD’s dusty inland and salty coastal air, they clog fast—cutting efficiency by 20% and risking system failure.

Quick fix:

• Unplug the unit

• Brush or vacuum coils monthly

• For rooftop or outdoor units, rinse gently with a hose
  A clean coil means cooler performance—and lower energy bills.

2. Check and Clean the Evaporator Coils: Keep the Chill Flowing

Evaporator coils are your cold-makers. But dirt and ice act like blankets, choking airflow and slashing cooling power by 15%, per Carrier.

What to do:

• Inspect coils weekly

• Defrost if frost forms

• Clean with coil cleaner or a soft brush
  When clean, they maintain steady temps that keep products fresher, longer.

3. Inspect and Replace Door Seals: Lock in the Cool

Worn or cracked gaskets leak cold air and invite humidity in—forcing compressors to work harder and increasing power use by up to 30%.

QLD tip:

• Use the paper test: close the door on a strip of paper. If it slips out easily, replace the seal.

• Check quarterly in coastal areas where salt accelerates wear.
  New seals are a cheap fix with big returns in energy and performance.

4. Adjust Thermostat Settings: Smart Settings, Smarter Savings

Overcooling costs you—each unnecessary degree below spec burns 3–4% more energy.

Best practice:

• Set fridges at 5°C, freezers at -18°C

• Use a digital thermometer to double-check actual temps

• Log readings twice daily—especially during QLD’s peak heat

Finding the sweet spot protects your products and your power bill.

5. Ensure Proper Airflow: Don’t Let Your Units Suffocate

Refrigeration systems need room to breathe—blocked airflow leads to overheating and failure.

Check this:

• Maintain 1–2 metres clearance around units

• Keep vents unblocked

• Shade outdoor condensers where possible
  A clutter-free zone means a longer-lasting system—and fewer $5,000 compressor swaps.

6. Schedule Regular Maintenance: Prevention Beats Panic

Think of maintenance like a check-up—spot issues early, avoid disaster later. In QLD, where humidity and heat push systems hard, routine service is non-negotiable.

Your checklist:

• Clean coils

• Check refrigerant levels

• Inspect electricals and controls

• Clear drain lines (especially before the wet season)
  A technician can catch what you can’t—and save you from peak-season chaos.

✅ The QLD Advantage: Prep Now, Save Later

• A Toowoomba café saved $2,000 in stock by catching a worn fan before it failed.

• A Sunshine Coast retailer slashed their power bill 15% with pre-summer maintenance.

• A Brisbane pub avoided a $10,000 compressor replacement by clearing blocked coils in time.
