Introduction
A Costly Problem in Plain Sight
At ACRO Refrigeration, we’re used to receiving urgent calls from Brisbane and Gold Coast commercial kitchens—but this one stood out. A major Brisbane hotel, just two years old, reached out after staff noticed one of their under-bench freezers wasn’t holding temperature. The digital display read +17°C—dangerously high for a unit that should be maintaining -18°C to -20°C.
In a busy kitchen, that kind of temperature swing can mean spoiled stock, compliance breaches, and even temporary kitchen closures.

The Root Cause: A Blocked Condenser Coil
When our technician arrived onsite, the issue was immediately clear:
“The condenser coil was so clogged with dust, grease, and debris that you couldn't even see the fins.”
Despite the hotel being relatively new, the freezer’s location—under a prep bench, in a hot and humid kitchen—meant it had accumulated grime fast. Without regular cleaning, the coil couldn’t dissipate heat properly, forcing the compressor to work overtime with little effect.

The Solution: Deep Clean and Preventative Insight
Our technician performed a thorough clean of the condenser coil, using nitrogen to blow out embedded debris and a coil-safe cleaner to remove the built-up film of grease and dust. The airflow was restored, and within hours, the freezer temperature dropped to a steady -21°C.

What This Means for Your Business
This incident is a textbook example of how preventative maintenance saves money—and headaches. Here’s why:
- Dirty condenser coils are the #1 cause of freezer temperature failure in commercial kitchens.
- Even new equipment is vulnerable without a maintenance plan.
- A single service call prevented a potential compliance issue, stock loss, and equipment burnout.
Takeaways for Facility Managers and Chefs
- Schedule routine coil cleaning at least every 3–6 months.
- Inspect under-bench units more frequently, especially those in tight or enclosed spaces.
- Partner with a service provider who understands the pressure of hospitality and compliance requirements.
Don’t Wait for a Breakdown
If your refrigeration units haven’t had a coil clean in the past 6 months, you're likely running at reduced efficiency—and increased risk.
